8 AVX-400 Enova Twisted Pair Presentation Switcher Operation/Reference Guide AXLINK All AVX-400 units have an AxLink port and adjacent status LED (FIG. 10). This port allows the unit to be controlled from any AxLink Master such as a NetLinx NI Controller. A green LED shows AxLink data activity. When the AxLink port is operating normally, blink patterns include: Off - No power, or the controller is not functioning properly. 1 blink per second - Normal operation. 3 blinks per second - AxLink bus error. Check all AxLink bus connections. To use the 4-pin 3.5 mm mini-Phoenix (female) captive-wire connector for data communication and power transfer, the incoming PWR and GND cable from the 12 VDC-compliant power supply must be connected to the AxLink cable connector going to the Integrated Controller. FIG. 11 shows the wiring diagram. Always use a local power supply to power the Integrated Controller unit. Make sure to connect only the GND wire on the AxLink/PWR connector when using a separate 12 VDC power supply. Do not connect the PWR wire to the AxLink connector’s PWR (+) opening. ’ FIG. 10 AxLink Port The AVX-400 cannot be powered by this port or use the port to power other devices. FIG. 11 4-pin mini-Phoenix connector wiring diagram (using external power source) Top view Top view NI Master AVX-400 Local 12+ VDC power supply (coming from an external power supply) When you connect an external power supply, do not connect the wire from the PWR terminal (coming from the external device) to the PWR terminal on the Phoenix connector attached to the Controller unit. Make sure to connect only the AXM, AXP, and GND wires to the Controller’s Phoenix connector when using an external power supply. If the Master does not recognize that the AVX-400 is online again after you reboot the AVX-400, re-seat the AxLink connection or reset the Master.

9 AVX-400 Enova Twisted Pair Presentation Switcher Operation/Reference Guide DEVICE DIP Switches The 8-position AxLink DEVICE DIP switch sets the AxLink identification number for your AxLink device. Make sure the device number matches the number assigned in the software program. The following table describes the values on the AxLink DEVICE DIP switch. RS232 The RS232 control port is a bi-directional serial port used for display control via a PC or Novara ControlPad. Currently, the AVX-400 supports the Novara SP-08-AX 8-button keypad. The port uses a 3-pin 3.5mm Phoenix connector, and supports 9600 baud communications only. When communicating via RS-232, connect the wiring as shown in FIG. 14. When using a Novara SP-08-AX 8-Button keypad, connect the AVX-400 to the RS232 output port on the keypad. Consult the documentation for the Novara SP-08-AX 8-Button keypad for more information on the location of the RS232 port on the unit.

10 AVX-400 Enova Twisted Pair Presentation Switcher Operation/Reference Guide Configuration Port (PROG) The AVX-400 contains one low-speed type-B USB connection located on the front of the unit. Use a standard USB cable to establish a connection between the device and your PC's USB port. This connection enables you to program the switcher by using AMX DCS software. See the AMX DCS Software section on page 17 for more information. Power Connector The AVX-400 uses a 12 VDC-compliant power supply to provide power to the switcher through the front 2-pin 3.5 mm mini-Phoenix power connector. Use the power requirements information described in the product’s Specifications table to determine the power draw. The incoming PWR and GND cable from the power supply must be connected to the corresponding locations within the power connector. The current draw for the AVX-400 with no input plates is 750mA. The following table lists the current draw for each type of input wallplate you can connect to the AVX-400. You can use this information to determine the overall current draw of the AVX-400 and its components. To illustrate, an AVX-400 with 2 VGA wallplates, 1 Component wallplate, and 1 Composite wallplate draws: 750 + 140 + 140 + 160 + 110 = 1.3A FIG. 15 Configuration port FIG. 16 Power connector Wallplate Current Draw Component 160mA VGA 140mA Composite 110mA HDMI 98mA The above equation does not take into account an audio source, which can increase the draw by up to 1A depending on frequency and volume. This unit should only have one source of incoming power. Using more than one source of power to the Controller can result in damage to the internal components and a possible burn out. Apply power to the unit only after installation is complete.

11 AVX-400 Enova Twisted Pair Presentation Switcher Operation/Reference Guide Preparing Captive Wires You will need a wire stripper and flat-blade screwdriver to prepare and connect the captive wires. 1. Strip 0.25 inch (6.35 mm) of insulation off all wires. 2. Insert each wire into the appropriate opening on the connector (according to the wiring diagrams and connector types described in this section). 3. Tighten the screws to secure the wire in the connector. Do not tighten the screws excessively doing so may strip the threads and damage the connector. Wiring a Power Connection To use the 2-pin 3.5mm mini-Phoenix connector with a 12 VDC-compliant power supply, the incoming PWR and GND cables from the external source must be connected to their corresponding locations on the connector (FIG. 17). Follow these steps to wire a power connection: 1. Insert the PWR and GND wires on the terminal end of the 2-pin 3.5 mm mini-Phoenix cable. Match the wiring locations of the +/- on both the power supply and the terminal connector. 2. Tighten the clamp to secure the two wires. Do not tighten the screws excessively. Doing so may strip the threads and damage the connector. 3. Verify the connection of the 2-pin 3.5 mm mini-Phoenix to the external 12 VDC-compliant power supply.

Display control enables you to select a display to use for the output from your source inputs. Enabling display control makes the options for Make, Type, Model, and Display Power Down available. Make Select the manufacturer of the device you want to use. Type Select the type of device you want to use. Model Select the device model you want to use. Variable Display Polling Rate Use the up-and-down arrow buttons to allow only one command to execute in the set number of seconds. Switching Mode Click an option button to indicate the method you want to use to switch between source inputs. You can choose from Take-over Mode, Toggle Mode, and Priority Switching. Take-over Mode With Take-over mode, if you press the button on a wallplate connected to source input 1, then source input 1 becomes the active input. The same applies to source inputs 2, 3, and 4. Toggle Mode With toggle mode, if you press the button on any of the wallplates, then the selected video input changes to the next available input. For example, if you have all four inputs connected to video sources, pressing any button on any wallplate causes the active input to toggle from 1 to 2 to 3 to 4 to 1. If you only have inputs 1, 2, and 3 connected, the toggle sequence will be 1 to 2 to 3 to 1. Priority Switching Enables you to establish a priority order for displaying each input. The input device with the highest priority will always be sent to the output display as long as the input device remains powered on. When the power to the highest priority input device is turned off, the signal from the next active input device appears on the output display. These options are not available unless you select Priority Switching as the Switching Mode. See the Priority Switching section on page 20 for more information.

Enabling Display Control Display control enables you to select a display to use for the output from your source inputs. A display can be any type of video output device.

Select a Make, Type, and Model display from their respective fields. 4. Click Program Device to send the display device’s commands to the presentation switcher. Priority Switching Priority switching enables you to establish a priority order for displaying each input device. The input device with the highest priority will always be sent to the output display as long as the input device remains powered on. When the power to the highest priority input device is turned off, the signal from the next active input device appears on the output display. For example, you have a DVD player set at priority 1, a PC at priority 2, and a VCR at priority 3. If the PC is always powered on, it’s output is sent to the display provided the DVD player is currently powered off. When the DVD player is powered on, its output is immediately sent to the display. Powering off the DVD player returns the PC’s output to the display. The VCR’s output is only sent to the display if it is powered on, and the DVD player and PC are both powered off. To set up priority switching: 1. In the Device Setup area, click the Display tab (FIG. 29). 2. Click the Priority Switching option button in the Switching Mode section. 3. Use the options menus in the Priority Switching area to indicate the priority order for each input device.

AMX advises you to place the AVX in passthru mode prior to executing a dynamic user command. Putting the AVX in passthru mode disables interrogation, and thereby eliminates the possibility of the polling commands interfering with the dynamic commands you send. Because of this, the AVX does not filter the responses back from the device, and extra data may be delivered to you. Syntax: DCM$0D Variables: text = The name of the dynamic command to trigger Example: DCM$0DAMX_FREEZE Note: The dynamic command has to be in the device library for the command to trigger.
