Broadcast Microwave Services 1 1 INTRODUCTION The DLC50 (Figure 1) is a control panel for airborne microwave systems in rotary or fixed-wing aircraft. It is user configurable for a large range of equipment and capabilities and is software upgradable. While the DLC50 is intended to functionally replace the HCP50-II, its capabilities extend far beyond those of the HCP50-II. Figure 1. DLC50 downlink control panel The DLC50 can control a transmitter, a receiver, an antenna actuator, RF Power Amplifier, and several external relays. See Figure 2. Control of transmitter and receiver are accomplished via dedicated or shared serial ports (user selectable). Remote control of DLC50 is possible by connecting another DLC50 via the remote control port. The remote DLC50 and the primary DLC50 will have equal priority control of all functions except the antenna actuator which remains dedicated to the primary DLC50. Alternately, the primary DLC50 may be slaved to an external flight computer for remote control, or a laptop may be used for direct access to the transmitter and/or receiver for transmitter/receiver maintenance. Updates of the DLC50 firmware may be made via the front panel serial port, while updates to channel plans, presets, preferences, etc. may be made via the front panel USB host port using a USB thumb drive. Configurations, preferences, and channel plans may also be saved to a USB thumb drive connected to the USB host port. A generic system diagram is shown below.

Broadcast Microwave Services 2 Figure 2. Generic DLC50 Microwave System Use of a BMS Power Voltage Relay (PVR) to distribute power to the microwave equipment enables the power switch on the DLC50 to control power to all attached devices. The PVR also provides a separate switched power connection for an external Power Amplifier (PA). The DLC50 is available in the models shown in Table 1. Any of these models may be used as a drop-in replacement for HCP50-II controllers when used with adapter cable 7314395012. Table 1.

DLC50 front and rear switches and ports descriptions Item Description 1 Panel Mounting Fasteners (Dzus) (x2) 2 Power Switch: Turns on the DLC50 control box and enables the external main system power relay, which in turn supplies power to all of the RF equipment (transmitters and receivers). 3 Antenna Actuator Switch: Primary control of antenna actuator; when switched to the “up” position, the TAA-101 retracts the antenna. When switched to the “down” position, the TAA101 deploys the antenna. The switch contains a “locked” position and must be pulled to switch. 4 Antenna Actuator Position Indicators: Green LED=Up, Amber1 LED=Down 5 Alarm Indicator: Amber 1 LED (dimmable) indicates fault condition. 6 OLED Display: Transmitter operating frequency and/or channel is displayed on the top line (6a) in double-size text. The middle line (6b) displays receiver frequency and status. During menu navigation it displays the active menu item. Other status may use the middle line while not navigating the menus. The bottom line (6c) labels the user- defined soft-keys. During menu navigation, the bottom lines become navigation keys.The OLED display is yellow 2. The display is dimmable. 7 Dual Rotary Encoder Control: A dual concentric rotary encoder with integrated push-button switch provides an intuitive means of navigating menus and making selections. 8 Preset Buttons: Three momentary pushbutton switches that are user-definable soft-keys. The user selected function is displayed on the bottom line of the text display (6c) above the key. 9 Transmitter Enable Button: A momentary pushbutton switch that toggles the RF enable command on and off. RF status is displayed on the text display. 10 USB Drive Port: Accepts USB thumb drive for updating firmware, channel plans, configuration, and presets. 11 Remote Port: Front panel access to the remote port (RS-232) allows a PC to be connected for configuration of attached transmitter or receiver, and other maintenance functions. This port is also available on the I/O Interface connector of the rear panel. Permanent installation connections should use the rear-panel connection for this port.. 12 Power In Connector: Power cable connection; see section 2.2 for details, pinouts. 13 I/O Interface Connector: Provides connections to various features such as dimming, Serial ports, and relay control; see section 2.2 for details, pinouts. 14 TAA-101 Actuator Control Cable Connector: Connects control cable to TAA-101 antenna actuator; see section 2.2 for details, pinouts. Note 1 - NVIS models use only class-B green LEDs Note 2 - NVIS models use a blue display and filter

Broadcast Microwave Services 4 1.1 Transmitter Serial Port (COM2) The transmitter serial port COM2 is used to control the attached transmitter and monitor its status. The serial port is setup in the configuration menu for the specific model of transmitter. The DLC50 will then configure the serial port for the correct control format and data rate for the specified transmitter. 1.2 Receiver Serial Port (COM3) Generally, the receiver will use serial port COM3. The receiver port is used to control the attached receiver and monitor its status.The serial port is setup in the configuration menu for the specific model of receiver. The DLC50 will then configure the serial port for the correct control format and data rate for the specified receiver. 1.3 Remote Serial Port (COM0) The Remote Serial Port (COM0) is a multifunction serial port that is accessible on both the rear panel and the front panel. The specific function is user selectable via the menu system. The remote port is disabled by default, but the following types of functions are supported: Remote Primary, Remote Secondary, Remote Client Serial, Pass-thru (TX port), Pass-thru (RX port), and Programming. Each of these modes is discussed below. Although the Remote Serial port is available on both the front panel and the I/O connector on the rear panel, more permanent connections (such as remote client, remote primary or remote secondary) should use the I/O connector on the rear panel. The front panel connection is intended to be convenient and compact for occasional short-term connections (such as TX pass-thru or RX pass-thru) during maintenance only. The remote primary and remote secondary modes allow a second DLC50 (the secondary) to connect to a DLC50 (the primary) that is installed in an aircraft. This allows the secondary DLC50 to act as a secondary point of control for the microwave equipment. The secondary DLC50 mimics the primary DLC50 providing identical displays and control of any attached transmitter and receiver. TAA-101 actuator control is reserved for the primary DLC only. On power-up, the secondary DLC50 will display an initial “splash” screen, then a second “splash” screen will display “Remote Secondary Mode” “Press any key to cancel”. A 10 second countdown will display. If a key is pressed during the 10 seconds, the remote port will be changed to disabled and the DLC50 will enter “normal” mode. If no key is pressed within the countdown, the DLC50 will enter Remote Secondary Mode and begin communications with the primary DLC50. To cancel remote secondary mode, select none in the config:remote port menu. “Remote Client Serial” mode uses the DLC50 variant of the WDTSII remote control protocol to control specific functions on the DLC50 and any connected transmitter or receiver through a single serial port. Commands are directed to either the transmitter, receiver, or DLC50 by use of selective addressing. Commands directed at the transmitter should use the address A5h. Commands directed to the receiver should use A6h as the address. And commands directed specifically to the DLC should be addressed to A4h. See separate DLC50 Remote Client Serial Protocol document. “Pass-thru TX port” mode echoes data to and from the TX serial port. This allows an easy method for direct connection from a PC to an attached transmitter without removing the DLC50 to access the rear panel connections. The DLC50 TX port must first be properly configured for the correct transmitter attached to the TX port. Baud rate and port settings are copied from the TX port settings. The second line of the display will show “Pass-Thru TX port”. While the DLC50 remote port is in pass-thru mode, all other communications to the receiver and transmitter ports will be inhibited. Pass-Thru RX port mode echoes data to and from the RX serial port (see Pass-thru TX port above.) Baud rate and port settings are copied from the RX port settings. The middle line will display “Pass- Thru RX port” on the second line of the display. While the DLC50 remote port is in pass-thru mode, all other communications to the receiver and transmitter ports will be inhibited. A programming mode is provided that uses the BMS update tool. The display shows a static warning that the program is being updated.

Broadcast Microwave Services 5 2 INSTALLATION Mechanical installation of the DLC50 in the aircraft requires 1.5” of vertical space in a standard MS25213 aircraft equipment panel. Dzus ¼-turn fasteners lock the DLC50 into the stardard rails. Installation location should allow for easy operator viewing and operation. Figure 5. Panel mounting dimensions recommended for the DLC50 (per MS25212C) 2.1 Installing the DLC50 (replacing an HCP50-II) Installing the DLC50 as a replacement for an HCP50-II in an existing installation is very simple. Power and Actuator cables are the same and can connect directly to the power and actuator connectors on the rear panel of the DLC50. The I/O connector has been expanded to 25 pins and requires an adapter to connect to the wiring harness in existing HCP50-II installations. 1. Connect the appropriate adapter cable, listed below, from the 10-pin connector of the existing wire harness to the 25 pin I/O connector on the DLC50. BMS provides the following cables for these connections: a. 7314395011 – DLC50 TO HCP50 ARINC (used when DLC50 replaces an HCP50 with a CTxx40ARINC transmitter) b. 7314395012 – DLC50 TO HCP50, CCII/HCII (used when DLC50 replaces an HCP50 with a CCII/HCII transmitter) 2. Connect the power and actuator cables to the appropriate rear-panel connectors. 3. Position the DLC50 into its mounting slot in the control panel and turn fasteners ¼ turn to lock in place. Consult Figure 5 for nominal panel size and dimensions. 4. Secure wire harness and adapter. 2.2 Installing the DLC50 (new installation) A new installation of the DLC50 will vary depending on the types of microwave hardware to be controlled in the system and how much of the system wire harness has been already prepared by BMS. (Contact BMS for assistance with wire harness design and prefabrication.) If the cable harness has been prepared by BMS, then most connections will already be made in the harness. Additional

Broadcast Microwave Services 6 functions which can be added at this time are external cockpit panel dimmer voltage (0-28V), remote serial connection (such as a secondary DLC50), and any external relay/switch controls that are desired Figure 6. DLC50 TO HCP50 harness (CCII/HCII) adapter (BMS# 7314395012) Figure 7. DLC50 to HCP50 harness (CTxx40ARINC) adapter (BMS# 7314395011) to be added to the open collector outputs OC1-OC4. See following sections for detailed electrical connections. Once all additional connections are added to the wire harness, installation in the instrument panel is as follows: 1. Connect the 25 pin I/O connector of the wire harness to the DLC50. To DLC50 To Existing Cable To DLC50 To Existing Cable

Broadcast Microwave Services 7 2. Connect the 4-pin power and 6-pin actuator cables of the wire harness to the appropriate rear- panel connectors. 3.

DC return (GND) is connected to pin C of the four-pin power connector. DC input power to the DLC50 should be powered from the same circuit breaker as the rest of the microwave system components, including any external relays. The power switch on the DLC50 can control DC power to all components of the microwave system when a Power Voltage Relay (PVR) is used as a power distribution hub for the microwave system components. The PVR will provide continuous power to the DLC50. The DLC50, when switched on, will signal (using the “system power on/off” signal on pin D of the 4-pin power connector) the PVR to provide DC power to the connected equipment. BMS manufactures cable P/N 7314189010 to provide the power and power control connections between the DLC50 and the PVR. Contact BMS Customer Service for more information. 2.5 Transmitter Connections Transmitter connections to the DLC50 are generally limited to RS232 serial port COM2. Transmitter commands from the DLC50 to the transmitter are output on pin 4 of the 25 pin I/O connector. Status back from the transmitter will come back to the DLC50 on pin 5 of the 25 pin I/O connector. Data ground for the COM2 serial port is on pin 6 of the 25 pin I/O connector. CCII and HCII transmitters have the ability to daisy-chain RS232 signals. The CCII/HCII serial connections are labeled PC Status, and PC Command. CTxx40ARINC-HD transmitters use DATA_TX as status, and DATA_RX as command. In addition, the CTxx40ARINC-HD transmitter requires a switched 5V and switched 28V signal to be provided by the DLC50 controller. Switched 28V is available on pin 16, and switched 5V is available on pin 15 of the 25 pin I/O connector. Signal return (GND) for the switched voltage signals is available on pin 21. Do not attempt to power any devices from the switched 28V or switched 5V outputs from the DLC50. These are signal level only. The transmitter type must be set up in the configuration menu. See Configuration section.

Broadcast Microwave Services 11 2.6 RF Power Amplifier Connections An external RF power amplifier requires only a PA standby/operate signal connection to the DLC50. The PA standby/operate signal is available on pin B of the four-pin power connector. When a PVR (power voltage relay) is used in the system, this PA standby/operate signal will be routed through the PVR for cabling convenience. No special configuration is required for the PA. 2.7 Receiver Connections Receiver connections to the DLC50 are generally limited to RS232 serial port COM3. Receiver commands from the DLC50 to the receiver are output on pin 1 of the 25 pin I/O connector. Status back from the receiver will come back to the DLC50 on pin 2 of the 25 pin I/O connector. Data ground for the COM3 serial port is on pin 3 of the 25 pin I/O connector. The receiver type and serial port must be set up in the receiver configuration menu. Typically the receiver port configuration will be set for COM3. In some cases, the receiver may be daisychained to a transmitter. In this case, the receiver’s PC_command and PC_status lines will connect to the DS_Command and DS_Status lines of the transmitter. The receiver serial configuration must be configured for COM2 in this case and the receiver will have no direct connection to the DLC50. See Configuration section. 2.8 Remote Connections The remote serial port is a multifunction serial port. Connection to the COM0 port is available through both the front panel 2.5mm connector, and the rear panel 25-pin I/O connector. Only one device may connect to the COM0 serial port, so if a rear panel connection is made, the front panel connector will not be available for use. The rear panel connection should be used for any permanent or semi- permanent installations. The Remote Port (COM0) must be properly configured for the desired functionality prior to use. See Setup and Configuration section. External Computer Control If an external computer is used in the system to control the DLC50 and attached microwave equipment, the connections should be made to the rear panel connections. The commands to the DLC50 will connect to pin 8 of the 25 pin I/O connector. The status will come out of the DLC50 on pin 7 of the 25- pin I/O connector. Data ground is on pin 9 of the 25 pin I/O connector. The Remote port must be configured as remote client in the configuration menu. The external computer will communicate with the DLC50 using BMS DLC50 Remote Client protocol. (Contact BMS for more information.) Remote Control (Primary DLC50 to Secondary DLC50) A second DLC50 (acting as a secondary remote) may be connected to COM0 of the primary DLC50. Both the primary DLC50 and secondary DLC50 will use the Remote/Auxilary serial port COM0. The TXD and RXD data lines must be crossed (as in a null-modem) for proper connection. The remote serial port must be configured as “primary” on the primary DLC50 and “secondary” on the secondary DLC50. The secondary DLC50 functions as a remote terminal to the primary DLC50. No other signal connections should be made to the secondary DLC50. DC power must be supplied via the four-pin power connector as described in section 2.4. Figure 14. Remote Primary to Secondary “null-modem” connection

Broadcast Microwave Services 12 Laptop Connection A laptop may use the Remote/Aux serial port (COM0) as a direct connection to a connected transmitter or receiver for maintenance functions so long as the Remote/Aux serial port (COM0) is not connected to any other devices on the rear I/O connector. The remote serial port must be configured as “TX pass- thru” or “RX pass-thru” to connect to the COM2 or COM3 ports respectively. The COM0 port baud rate will be set up to match the selected transmitter or receiver port baud rate. BMS manufactures a serial cable (Figure 15; BMS P/N 7314395013) to allow connection of a laptop serial port to the DLC50 front- panel serial connector for pass-thru modes for transmitter and receiver maintenance. Figure 15. Front panel 2.5mm serial cable 2.9 Actuator Connections The six-pin actuator connector is a pin-for-pin connection to the TAA-101 antenna actuator. The actuator control and status LED indicators are active even when the DLC50 front panel power switch is off. BMS cable P/N 7314189070 provides the connection between the DLC50 and TAA-101 actuator. 2.10 Relay Connections Relay configuration is very flexible and customizable. The DLC50 provides four open collector transistors for controlling relays and external switches. Each relay driver (OC1, OC2, OC3, OC4) can be configured for manual control or automatic control based on frequency of the transmitter. An upper and lower frequency limit can be set in the configuration for each “automatic” relay. By careful planning of limits, multiple channel filters, sub-band filters, diplexers, and multiplexing switch arrays can be configured. Any relay in the transmission path (whether manual or automatic) can also be configured for hot-switch protection. If a relay is hot-switch protected, the transmitter will be forced off before switching, then the transmitter will be returned to its previous state after switching. See relay configuration section, or contact BMS Customer Service for more information. An external relay can be powered by 28V or less, but the relay must be powered by the same circuit breaker that powers the DLC50 or the PVR. Relay drivers in the DLC50 provide a switched ground to turn on the relay. Each relay driver can sink up to 500 mA. Only relays with built-in transient suppression diodes should be used, or transient suppression diodes can be added directly to the terminals of the external relay. SLEEVE

Broadcast Microwave Services 13 2.11 External Dimmer Connections A cockpit instrument dimming control voltage (0-28V) may be connected to the DLC50's "External Dimmer Control Input" to provide common dimming with other instruments in the cockpit panel. This external 0-28V signal may be connected to pin 14 of the 25-pin I/O connector. When connected to a common external dimming signal, manual dimming of the DLC50 from the dimming menu will allow trim adjustment of the DLC50 panel brightness to match other instruments at night time or night vision settings. If no external dimming control is desired, this pin may be left open (no connection). The DLC50 allows full manual dimming control from the front panel when not connected to an external dimmer control voltage.

Broadcast Microwave Services 14 3 DISPLAYS, CONTROLS AND MENU NAVIGATION The user interface on the DLC50 allows the user to navigate the menu system and monitor system status. The user interface consists of 4 pushbutton keys, a dual rotary encoder (with integral push button), a 3-line display and various LEDs. 3.1 Display and LEDs Figure 16. Normal Display The display is organized with the top line being double-height text, and the second and third lines being single-height text. The top line (double-height) is reserved for Transmitter channel/frequency status. If a channel plan has been loaded, the channel designator will show ahead of the frequency. If the selected frequency is not one of the channels in the channel plan, the channel designator will show as AN asterisk “*”. If no channel plan has been loaded, a blank space will precede the transmitter frequency. The second line is multi-functional, and will normally display the receiver channel/frequency information and selected meter status if a receiver is installed in the system. If no receiver is installed in the system, the second line may be blank or it may display other status information dependent on configuration. If a warning or fault occurs, the fault explanation will appear on the second line alternating with the normally displayed data. While navigating the menu system, the second line displays the current menu navigation information (menu group, item selection, etc.). Figure 17. Display showing TXEN status (transmitter on) The third line serves as a legend for the 4 keys below the display. The left-most key is the Transmitter Enable key. It is always available in all modes, and will display the current status for the transmitter. When the transmitter is off, the “TXEN” text will appear normal. When the transmitter is transmitting, the text will appear inverted against a solidly lit block as shown above. The other text on the third line displays the functions that the user has assigned to the three soft-keys. (See configuration section). Some soft-key functions toggle the state of the selected item (relays, encryption, decryption, etc.) In this case, the text will appear normal when the soft-key is toggled off, and backlit with inverted text when the soft-key is toggled on. During menu navigation, the third line text above the 3 soft-keys will change to navigation functions “EXIT”, “CANCEL”, and “OK”. The third line will return to the normal soft-key legends upon exiting the menu system. LED indicators provide a visual status of the TAA-101 actuator and alert the user to any system alarms. Actuator LEDs are activated by the upper or lower limit switches, indicating that the antenna has

Broadcast Microwave Services 15 reached its stowed “UP” or deployed “DN” position. While the actuator is in transition, neither LED will be lit. The alarm LED lights to indicate an alarm from the DLC50 or one of the attached microwave system components. The nature of the alarm will be displayed on the second line of the display. 3.2 Keypad The four-button keypad consists of the transmitter enable key (TXEN) and three user definable soft- keys. The TXEN key is dedicated to that function, and is always active. The soft keys may be configured by the user providing maximum flexibility for the specific installation or intended use. The third line of the display will identify the currently selected soft-key functions above each key. There are three basic types of soft-key functionality that can be assigned; toggle, immediate, and menu. 1. Toggle includes relay and encryption or decryption functions which turn on or off the selected item with each subsequent key press. When the selected item is turned on, it will backlight the legend text on the bottom line of the display. 2. Immediate includes specific channel or preset recalls. The channel or preset will immediately be selected when the key is pressed. 3. Menu functionality includes channel menu or preset menu and will launch the assigned sub-menu. The keypad is also used during menu navigation. When entering any menu or sub-menu, the three soft-keys change to menu navigation keys “EXIT”, “CANCEL”, and “OK”. EXIT immediately quits the menu system and returns to the normal display. Cancel backs out one level in the menu system. And OK, accepts the current menu selection or advances into a sub-menu. When the menu system is exited, the soft-key legends return to the user selected functions. See configuration section. 3.3 Rotary encoder The dual rotary encoder with integral push-button is used for menu navigation. This should be a familiar control to users of aviation GPS receivers and mapping devices. The outer knob of the rotary encoder is used to rotate through menu groups in the Expert Menus. The inner knob is used to rotate through menu items within the selected group. Once the user has navigated to the desired menu, the “OK” soft- key or inner knob is pushed to open that menu item. From there, the outer and inner knobs allow review and selection of various values and parameters in the selected item. Pressing OK will accept, pressing cancel will back out, and pressing exit will completely exit the menu system. Outer knob of rotary encoder selects menu group or selects edit field in sub-menus Inner knob of rotary encoder selects menu item in selected menu group or selects value for field in sub-menus Pressing inner knob enters sub-menu or accepts value change

Broadcast Microwave Services 16 In the simple menus, the outer knob rotates through the available simple menu item or items that have been previously configured by the user. See configuration section. 3.4 Menu Navigation Menu navigation is guided by the second line of the display which will identify the menu group, menu item, or parameter to be selected or changed. The active field will be backlit on the display line. There are two sets of menus available in the DLC50: the Expert Menu, and the Simple User Interface (Simple UI). Each is explained below. The Simple UI is a significantly reduced subset of the menu system, is user configurable, and is trimmed down to just a few common functions and sub-menus that the user will want or need to access during operation. The Simple UI allows easy access to common functions without the need to navigate unnecessary menus. For example, the Simple UI could be configured to enable only the TX channel selection and Encryption sub-menus. In this case, rotating the outer knob will advance from normal display, to TX channel selection, to Encryption, and back to normal display. The navigation keys also appear while the Simple UI is activated. Accepting a selection or pressing cancel or exit will return to normal display. The Simple UI is set up under Configuration>Simple UI from the Expert Menu. To switch between Simple UI and Expert Menus, turn off the DLC50, then hold the 1 and 3 soft-keys in while turning the DLC50 back on. Release the soft-keys after the splash-screen appears. The Expert Menu system is the complete menu system that allows selection of all parameters and functions controllable in the DLC50 and the attached microwave equipment as well as system configuration functions. Using the rotary encoder, the user may navigate the Expert Menu system by first selecting a menu group with the outer rotary knob, then the menu item with the inner rotary knob. Pressing OK or the inner rotary knob will enter the selected submenu. There are 5 menu groups: DLC Presets, TX, RX, Other, and Configuration. A listing of the 5 menu groups and their associated menus is presented below. Menu groups (and associated menus): DLC presets Recall, Erase, Save. Allows management of DLC50 Presets which may be configured to include TX and RX presets, channels, frequencies, and encryption/decryption states, as well as relay states. (See Configuration>Presets Setup) TX Frequency, Channel, Power, Recall Preset, Encryption. Menus for controlling transmitter related functions. Menu group will not appear if no transmitter configured. RX Frequency, Channel, Recall Preset, Decryption, Meter type. Menus for controlling receiver related functions. Menu group will not appear if no receiver configured. Other Relay Control, Dim Control. Menus for controlling miscellaneous DLC50 functions. Configuration Language, RX serial, TX serial, Remote serial setup, USB Flash functions, External Relay Setup, Presets setup, Simple UI setup, Soft-key setup, key-timer setup, system. Menus for configuring DLC50 and its connected microwave system components. Notes: The TX group will not appear if there is no transmitter configured. The RX group will not appear if there is no receiver configured. Additional menu items that are unique to a specific transmitter or receiver will also appear in the appropriate TX or RX menu group when properly configured. For complete menu group, menu, and sub-menu listing, see Appendix.

Broadcast Microwave Services 17 4 SETUP AND CONFIGURATION The DLC50 can control a variety of microwave system components and is very flexible. But it must be configured for the equipment first. The configuration can be modified in the Configuration menu group of the Expert Menu system. The configuration menu group consists of language setting, RX serial setup, TX serial setup, Remote serial setup, USB Flash functions, External Relay setup, presets setup, Simple UI setup, softkey setup, key-timer setup, and system functions. Each will be described in the following sections. 4.1 Language Setup Configuration>Language English or Spanish languages may be selected. The default language is English. Other language modules may be added. 4.2 RX Serial Setup Configuration>RX Serial>RX Model Configuration>RX Serial>Port If a receiver is to be used, the DLC50 must be configured to communicate with it. The serial configuration consists of selecting the correct model of receiver, and designating a serial port for the receiver. Normally the receiver will be installed on the COM3 port. RX serial configuration is set in the Configuration>RX Serial menu. In some limited installations, a receiver may share a serial port with a transmitter in a daisy-chain connection. In a shared configuration, COM2 may be selected for the RX serial port setting. The DLC50 will communicate with the receiver on the selected serial port using remote address A6h. The receiver may need to be configured to communicate on this address before installation. If no receiver is used in the system, the RX Model should be set to “none”. 4.3 TX Serial Setup Configuration>TX Serial>TX Model If a transmitter is to be used, the DLC50 must be configured to communicate with it. The serial configuration consists of selecting the correct model of transmitter. The DLC50 will communicate with the transmitter on COM2 serial port using remote address A5h. The transmitter may need to be configured to communicate on this address before installation. If no transmitter is used in the system, the TX model should be set to “none”. 4.4 Remote Serial Setup Configuration>Remote Serial Setup The remote serial port (COM0) is a multifunction port. The Remote COM0 port may be physically connected to on the rear panel (IO connector) or the front panel (2.5mm round), but not both. It may only have one connection made to it at a time. The front panel connector is provided for temporary connection for maintenance. Remote connections, other than maintenance, should use the rear panel I/O connection to COM0. The following configuration types for this port are discussed below None - When the COM0 serial port is not in use, it should be configured to “none”.

Broadcast Microwave Services 18 Primary – When two DLC50 units are connected together, the “primary” is the unit that connects directly to the microwave system equipment. (See installation section.) Secondary – When two DLC50 units are connected together, the “secondary” is the unit that is not connected to any other equipment and would be installed in a secondary operating position (possibly rear seat). It functions as a remote terminal and mimics the primary DLC50. Remote Serial – This setting allows an external computer to communicate with the DLC50 to control DLC50 functions and transmitter and receiver functions, as well as monitor all status. The external computer will use the BMS DLC50 Remote Client serial protocol to communicate with the DLC50. Pass-Thru TX – Used for Transmitter maintenance on COM2. Passes COM0 data through to COM2. The data rate is set by the protocol for the configured transmitter. Note – if receiver and transmitter are sharing COM2, then use “Pass-Thru TX” for maintenance on the receiver. Some levels of maintenance may require only one device on the bus at a time. Pass-Thru RX – Used for Receiver Maintenance on COM3. Passes COM0 data through to COM3. The data rate is set my the COM3 configuration. Note – if receiver and transmitter are sharing COM2, then use Pass-Thru TX for maintenance on the receiver. Some levels of maintenance may require only one device on the bus at a time. 4.5 USB Flash Functions Configuration>USB Functions The USB port may be used for loading and saving configurations, and presets. It may also be used for loading TX and RX channel plans, and software updates. To use the USB port, plug in a USB flash drive into the USB socket on the front panel. Go to the configuration menu group, and select USB Functions, then select the specific operation desired. USB loading operations will immediately access the specified file type selected and begin loading. Loading software will take a couple of minutes. The Alarm LED will flash with USB activity and the results will be displayed when completed. Other operations will complete almost instantly. If the correct file type or filename is not found, a “no file found” error will display. USB saving operations will save the file almost instantly. NOTE: The DLC50 will only access files in the root directory of the USB drive. USB operations use the following filenames: Software update DLCSOFT.hex DLC Presets file DLCPSET.dat TX channel Plan file DLCTXPLN.bin RX Channel Plan file DLCRXPLN.bin DLC Configuration file DLCCNFG.dat Filenames for any files to be loaded by the DLC50 must first be changed to match the above filenames for the type of file used. The same channel plan file may be used for both the transmit and receive channel plan, but they must be loaded separately and must be changed to the correct filename before loading. Contact BMS Customer Service department for Software updates or assistance with channel plans. Configuration files can be loaded and saved. If it is desired to archive different configuration files, rename them for easy identification, then copy just the desired configuration onto the flash drive and rename before loading.

Broadcast Microwave Services 19 4.5.1 Example: Loading a TX Channel Plan from a USB Thumb Drive Place the TX channel Plan file from BMS in the root directory of the USB thumb drive using the exact filename DLCTXPLN.bin (not case sensitive). 1. Turn on DLC50. 2. Plug in USB thumb drive. 3. Rotate outer knob until “Config: Language” is displayed. 4. Rotate inner knob until “Config:USB Flash” is displayed. 5. Press “OK” or end of inner knob. 6. Rotate inner knob until “Load: TX Channel Plan” is displayed. 7. Press “OK” or end of inner knob. 8. Unit will display “USB: Please Wait…” then “USB: Load … OK”. 9. Remove USB thumb drive and cycle power on/off. 4.6 External Relay Setup Configuration>External Relay Setup>RYn>Mode Configuration>External Relay Setup>RYn>Auto F Configuration>External Relay Setup>RYn>Invert Configuration>External Relay Setup>RYn>Hot SW Prot Mode - The 4 Open Collector relay drivers (RY1 – RY4) in the DLC50 can be configured as Manual or Automatic. Manual relays are commanded on or off by a user command (soft-key or menu selection) or as part of a DLC50 preset. Automatic relays are controlled by the frequency of the transmitter. Auto F sets the upper and lower frequency threshold for the specified relay. An automatic relay will be on when the frequency of the transmitter is between the lower and upper Auto F limits for that relay. (Unless invert is selected.) Invert inverts the frequency selection for a relay so that the relay is on when the frequency is outside of the upper and lower Auto F limits and off between the auto F limits. Hot Sw Prot – Hot Switch Protection for a relay assures that the transmitter will be off when the relay changes state. This option should be selected for any relays that are in the transmit RF path to protect the RF power amplifier and the relays from possible damage. When a hot switch protected relay is to be switched, the DLC50 will command the transmitter off (if it was on), switch the relay, then restore the transmitter to its previous transmitting state (standby or transmit). The relay control configurability allows multiple channel filters, or sub-band switches to be automatically controlled. An array of 4 channel filters can be controlled using only 2 relay drivers as shown below.

Broadcast Microwave Services 20 Figure 18. Diplexer subband switching configuration example Figure 19. Multiple subband filter array configuration example Using an external booster relay, a similar filter array for receive filters (that provide rejection of the transmitted signal) could be controlled with the same two relay drivers. That still would leave 2 available relay drivers for additional functions such as antenna switch, or other ancillary function. A booster relay is required if relay switching current exceeds 500 mA. Contact BMS Customer Service for more information. 4.7 Presets Setup Configuration>Presets Setup The DLC50 can store up to 20 highly configurable presets. These are not to be confused with transmitter or receiver presets which are separately controllable from the TX or RX menus. The DLC50 presets allow the user to create presets that contain any or all of the following settings: Name, TX channel, TX frequency, TX preset, TX RF power, TX encryption state, RX channel, RX frequency, RX preset, RX decryption state, and relay state (of manual relays only). So a single DLC50 preset could recall both an RX preset and a TX preset, and another could store TX frequency only, while another could store receiver channel only. Each possible parameter that can be stored in a preset is selected or deselected in the preset setup configuration. When a DLC50 preset is saved, only the parameters selected by the user, will be saved in the DLC50 preset. The Preset setup list may be changed for each preset if desired. 4.8 Simple UI Setup Configuration>Simple UI The DLC50 has an extensive Expert Menu system that provides a broad range of controls and options for system configuration, control, and maintenance tasks. But only a few items will generally need to be changed or accessed during actual system operations. The operator typically will be performing many other tasks in addition to managing the DLC50 so the Simple User Interface (Simple UI) was created to

Broadcast Microwave Services 21 limit the accessible menus and functions to only those items the user will need or want to have access to during normal operation. The following items may be included in the Simple UI: Recall DLC Preset, TX Set Chan, TX Set Freq, TX Set Preset, TX Set RF Power, RX Set Chan, RX Set Freq, RX Set Preset, Encrypt Toggle, Encrypt Menu, Decrypt Toggle, Decrypt Menu, RY1 Toggle, RY2 Toggle, RY3 Toggle, RY4 Toggle, Dim Control. Just one or two items included in the Simple UI combined with thoughtful soft-key assignments will streamline the operation of the entire microwave system. To toggle between Simple UI and Expert Menus, hold down soft-keys 1 and 3 while switching on power. The current selection confirmed on the display after the splash-screen. 4.9 Soft-Key Setup Configure>Soft-Key Setup>Key n> The three soft-keys may be assigned any of the following functions by the user: PSET Launches DLC Preset menu Pnn Instantly selects preselected DLC preset # nn. TXCH Launches TX Channel menu TXPS Launches TX Preset menu Txxx Instantly selects TX channel # nn from the TX channel plan stored in the DLC50. TPnn Instantly selects TX preset # nn stored in the transmitter. RXCH Launches RX Channel menu RXPS Launches RX Preset menu Rxxx Instantly selects RX channel # nn from the RX channel plan stored in the DLC50. RPnn Instantly selects RX preset # nn stored in the receiver. ENCR Toggles encryption on/off. DECR Toggles decryption on/off. RY1 Toggles relay driver 1 (must be configured as manual relay) RY2 Toggles relay driver 2 (must be configured as manual relay) RY3 Toggles relay driver 3 (must be configured as manual relay) RY4 Toggles relay driver 4 (must be configured as manual relay) DIM Launches Dim Control menu to allow manual dimming or dim level trimming. 4.10 Key-timer Setup Configuration>Key-Timer The Key-Timer functions as a menu activity timeout timer. While in the menu system, if there is not key or rotary knob activity for the selected time-out period, the DLC50 will exit the menu system and return to the normal display. The default key-timer value is 20 seconds. Values of 10-60 seconds may be selected, or the time-out timer may be disabled by selecting “off”. 4.11 System Functions Configuration>System The system menu will allow the user to read back the firmware version of the DLC50. (Some transmitters and receivers will also report their firmware versions to the DLC50 and may also be reviewed in this menu.) The “Restore Defaults” option can be used to recover from a bad configuration file load or in some cases, may be required when updating software. Selecting the “restore defaults” option will overwrite any configuration settings that have been entered. It is recommended to save configuration to the USB flash drive before restoring defaults.

Broadcast Microwave Services 22 5 OPERATION This section contains instructions for specific common operations of the DLC50. It is organized by operation topic. The following topics are discussed: selecting a TX channel, selecting a TX frequency, Selecting a TX preset, setting encryption, setting RF power level, changing the RX meter display, Dimming the display. The Display, Controls, and Menu Navigation section (chapter 3) should be consulted prior to operating the DLC50. 5.1 Selecting a TX or RX Channel A TX channel plan must already have been loaded into the DLC50 or the TX channel select menu will not appear. Navigate to the TX>Channel menu and press the OK button (or inner knob). The channel number will backlight indicating the field that is being edited. Rotate the inner knob until the desired channel is indicated and press OK or press the inner knob to accept. Notice the channel number and channel frequency are displayed on the top line of the display. RX channel selection is similar, except the process starts by navigating to the RX>Channel menu. Receiver channel and frequency will be displayed on the second line of the display. 5.2 Selecting a TX or RX Frequency To select a transmitter frequency navigate to the TX>Frequency menu and press the OK button (or inner knob). The 1000’s digit of the transmitter frequency displayed on the top line will be highlighted. Use the outer knob to highlight different digits of the transmitter frequency, and use the inner knob to change the value of the highlighted digit. Press OK when finished. The top line of the display will now display the new frequency. If the selected frequency matches a channel in the the TX channel plan, the corresponding channel number will also be displayed. If the frequency does not match a channel in the channel plan, an asterisk “*” will display in the channel number location. If no channel plan is loaded for the transmitter, then the channel number location will be blank. RX frequency selection is similar, except the process starts by navigating to the RX>Frequency menu. Receiver channel and frequency will be displayed on the second line of the display. 5.3 Recalling a TX or RX Preset TX presets are memories located in the transmitter that, depending on the transmitter model, store frequencies, modes, and other settings. Refer to the specific transmitter’s manual for information regarding the the number of transmitter presets and their contents. To select a TX preset, navigate to the TX>Recall Preset menu and press OK. Use the outer and inner knobs to indicate the desired TX preset number and press OK. The new transmitter frequency will be displayed on the top line and the display will return to the normal display. RX preset selection is similar, except the process starts by navigating to the RX>Recall Preset menu. The new receiver frequency will be displayed on the second line of the display. 5.4 Recalling, Saving and Erasing a DLC50 Preset DLC50 presets can be customized by the user in the Configuration>Presets menu. Individual DLC Presets may be assigned to Soft-keys, or the DLC preset menu can be launched by a soft-key or from the Simple UI. (See setup and configuration chapter) To recall a DLC50 preset: 1. Navigate to DLC Preset>Recall and press OK.

Broadcast Microwave Services 23 2. Rotate the inner knob to select the desired preset (P01-P20) and press OK. To Save a DLC50 Preset: (saves current settings of parameters in preset parameter list) 1. Configure the preset parameter list (see Configuration>Presets menu). 2. Navigate to DLC Preset>Save and press OK. 3. Rotate the inner knob to select the desired DLC preset number (P01-P20) and press OK. 4. Using the inner and outer knobs, set the description text (up to 16 characters) and press enter. To erase a DLC50 preset: 1. Navigate to DLC Preset>Erase and press OK. 2. Rotate the inner knob to select the preset to be erased and press OK. 5.5 Setting Encryption or Decryption The TX>Encryption menu has 3 sub-menus for encryption on/off, encryption type, and encryption key (or PIN). Navigate to the TX>Encryption menu and press OK. Using the outer and inner knobs, select the desired on/off setting, and the encryption type. (Note AES and BISS encryption require optional licensing.) For BMS type encryption (BMS-4, BMS-A and BMS-B), turn the outer knob to display PIN and press OK. Use the outer and inner knobs to set the 4 or 6 digit key. Press OK when finished. For AES or BISS type encryption (BCRYPT-A, BCRYPT-B, BISS, BISS-E), rotate the outer knob to display “select AES Key” then rotate the inner knob to select the key index number (1-16). Press OK when finished. RX decryption is similar, except the process starts by navigating to the RX>Decryption menu. 5.6 Setting RF Power Level If the attached transmitter supports multiple RF output power levels, the TX>RF Power menu will let you select the desired RF power level. Navigate to the TX>RF Power menu and press OK. Rotate the inner knob to select the desired power level and press OK. 5.7 Changing the RX meter Type The meter display type can be changed between RSSL (Received Signal Strength Level), BER (Bit Error Rate) and RSQ (Receive Signal Quality which is a hybrid of RSSL and BER). To change the receiver meter type navigate to the RX>Meter Type menu and press OK. Rotate the inner knob to the desired meter type and press OK. The new meter type will be displayed on the second line of the display. 5.8 Dimming the Panel and Display The DLC50 panel brightness can be controlled by a common external 0-28V cockpit instrument dimming circuit, or it can be manually adjusted. Depending on the installation, if an external dimming control is connected to the DLC50 dimming input, then the external control should generally be used to adjust the panel brightness. In this case, the DLC50 dim menu will allow the panel brightness of the DLC50 to be trimmed to match other instruments at low-level settings of the external dimmer. In installations where the DLC50 is not connected to the external dimming control, the Dim menu can be used to adjust the DLC50 brightness over the entire adjustment range.

Broadcast Microwave Services 24 With External Dimming Control 1. Adjust the cockpit common dimming control to the night operation level (or NVG level if so equipped). On the DLC50, navigate to the Other>Dim Control menu and press OK. 2. Rotate the inner knob to increase or decrease the brightness of the DLC50 front panel until it matches the illumination level of the other instruments on the same external dimmer control. Press OK. The DLC50 brightness will now track the other instruments connected to that dimmer control. Without External Dimming Control 1. Navigate to the Other>Dim Control menu and press OK. (This menu may also be assigned to a soft-key or can be added to the simple UI for easy access). 2. Rotate the inner knob to the desired brightness and press OK.
