SECTION 1 GENERAL INFORMATION 1.1 GENERAL The purpose of this manual is to describe the proper installation and operation of the Wegener Communications UNITY4000 MPEG Video Integrated Receiver Decoder. 1.2 INTRODUCTION The UNITY 4000 IRD is an integrated receiver/decoder designed to receive SCPC or MCPC DVB-compliant digital video signals transmitted by satellite. The input to the IRD is an L-band (950-2150 MHz) RF signal which is processed to produce composite video, audio, E-mail output, auxiliary data, and relay cueing signals. The IRD is fully network-controlled via the WCI COMPEL control system. The optional decryption feature for the IRD allows for use of WCI conditional access. Authorization of each IRD is under network control. In addition to network control, the IRD features a front-panel LCD interface for gathering local status information. In addition, limited control of the IRD (if allowed by the COMPEL network) may be implemented via serial port, connecting either to a local terminal (or via phone modem) to a remote terminal. The IRD has expansion ports for up to two add-in modules. Contact the Wegener Sales Department about available options. 1.3 UNPACKING AND INSPECTION Carefully unpack the unit and inspect it for obvious signs of physical damage that might have occurred during shipment. Any damage claims must be reported to the carrier immediately. Be sure to check the package contents carefully for important documents and materials. 1.4 PHYSICAL ENVIRONMENT Mount the UNITY4000 IRD in a standard EIA 19-inch equipment rack located in a clean, dry environment, and do not place unsupported equipment on the unit. Make sure that total rack power consumption does not exceed the limits of the AC branch circuit, and that a reliable earth safety ground is maintained. The unit will meet the full 10-40oC operating temperature specification only if adequate clearance around vent-holes is provided. The units may be arranged

SECTION 2 SYSTEM CONFIGURATION 2.1 UNIT OVERVIEW The UNITY 4000 IRD features several separate hardware components, including the DC switching power supply, the main motherboard, an L-band DVB receiver, front-panel keypad controller card, a front-panel LCD assembly, and the L-band RF switch. The DC switching power supply provides all internal regulated DC power. The optional L-band RF switch is installed in the Module 2 expansion slot, and provides network or (if allowed by the network) local user selection of up to four separate RF feeds. The selected RF feed output is connected to the DVB-compliant L-band receiver card. This card tunes and demodulates the input QPSK carrier, and then applies two layers of error correction decoding. Its output is the original (possibly encrypted) multiplex MPEG transport stream which was input to the uplink IF modulator. This stream then feeds the main motherboard, which decrypts (if necessary) the stream and then demultiplexes out the selected video and audio elemental streams. These are, in turn, de-compressed and converted back to the original analog source material for output. Meanwhile, the user may query the IRD using the front-panel keypad for input and the LCD to read the returned status information. 2.2 BLOCK DIAGRAM DISCUSSION Refer to Figure 1, Page 15 for the following discussion. The DVB-compliant receiver card demodulates the incoming QPSK carrier. It implements both FEC decoding and de-interleaving per the DVB standard. The decoded byte stream is output to the main board. The input to the main board is the multiplexed MPEG2 transport stream. If encryption is active, then the decryption function is executed. The resulting ÒclearÓ transport stream is then made available for output on the TRANSPORT OUT connector at the rear of the unit. In parallel, that stream is fed to the transport demultiplexer, this device selects the component elemental stream for selected video and audio programs, as well as the network control data streams. The selected video data is passed to an MPEG video decoder which converts the signal to linear digital video. This is then converted to analog NTSC in a final encoder for output. Meanwhile, the selected MPEG compressed audio stream is also routed to a combined decompression and digital-to- analog converter IC. The output is one stereo pair of audio signals (L and R) on Channel 1 at the back panel. In addition to the first stereo pair, a digital signal processor monitors and demultiplexes out another selected digital audio stream, which is also decoded and output as the stereo pair on Channel 2 at the back panel.

The control system on the main board is run by the main host processor. This processor interfaces with the COMPELª network as well as local users and then controls and monitors the unitÕs operations. To do its job, this processor accesses the control data streams recovered from the main transport demultiplexer. One of these may be a conditional access data stream (if used). The main processor sends this data to a separate secure microprocessor, which looks to see if its unit serial number is authorized to receive the broadcast signal and, if so, recovers the secret keys for decrypting the incoming encrypted transport stream. Meanwhile, the main host processor also communicates with several peripheral devices. It manages the data passed to/from the front-panel keypad controller (which lights status LEDÕs, manages an LCD display, and reads back keypresses). It manages the two serial ports which may be configured for printer, terminal, modem, or auxiliary data output. It also controls the L-band receiver daughtercard and any installed options modules (such as the RF switch). For maximum flexibility, and to make value-added upgrades easily possible, the operating unit software is stored in flash memory and may be dynamically replaced via the local serial port or from the satellite network control channel. 2.3 SPECIFICATIONS The receiver uses an integrated tuner and QPSK demodulator assembly. 2.3.1 L-Band Tuner The tuner specifications are shown below. Table 2.

The total AC current consumption with the 4:1 RF switch option and max LNB DC load is 0.8A at 115 VAC, and 0.5A at 230 VAC. 2.3.14 LNB DC Power The unit may feed DC power to an external antenna-mounted LNB using either the RF-In connectorÕs center-pin or a terminal on the rear-panel terminal strip (with an external DC power inserter). The nominal voltage supplied is +17 to +24 VDC, while the maximum load current is 250 Ma. The output is short-circuit protected by a thermal fuse. A rear panel MODE DIP switch may be used to activate/de-activate the DC output (See Section 2.4.2.1). An internal jumper (J22) is used to enable/disable DC power on RF-In center-pin. (Therefore, to get DC power on the RF-In center pin, both J22 and DIP switch must be set.) 2.3.15 Four Input / One Output RF Switch (Optional) 2.3.15.1 Description The module is installed into the MODULE 2 option-slot position on the back of the parent IRD. It allows the IRD to select one of four antenna / LNB inputs when its RF OUTPUT jack is connected via a 75-ohm coax cable to the IRD RF INPUT. There is no power pass for LNB DC power. (DC for the LNB is provided on the UTY4000 rear terminal strip and requires an external DC power inserter. No DC voltage is applied to any F connector.) The input and output RF connectors are Type-F jacks, and they are located on the option module rear panel.

Each Channel (Ch1 & Ch2) has a right and left mono pair. Each of these pairs is a balanced, low-impedance audio output, with terminals labeled Ò+, -, and com.Ó These are accessed through terminal strips which plug through the rear panel into the main PWB. These strips have screw terminals which accept standard audio cables. Please note that audio should be terminated with 600-ohm loads for correct output levels. 2.5.2 FCC-Mandated Suppression of Radiated Emissions In order to comply with the requirements of FCC Part 15 Subpart B, Class A emissions, please read the following instructions on the protection of all output wiring and cabling: For each monaural audio output (two per stereo channel), and for each alarm or user- controlled relay output THAT IS USED, a single ferrite core must be used for EMI emission suppression. The ferrite cores are supplied in the shipping container along with the Unity4000 IRD. Details on assembly of the ferrite cores on the wiring are shown in Figure 2. Note that each pair (or three, if the audio grounds are included) of wires must pass through the core twice. Be sure that this is done as close to the removable screw- terminal strip as possible. If minimal slack is used in the outer Òturn,Ó the ferrite core should be properly restrained by the wiring alone

2.5.3 Alarm Relay and Addressable Contact Closures The rear panel has an alarm relay and two network-controlled solid-state contact closures addressable from the COMPELª uplink computer. The alarm relayÕs ÒalarmÓ conditions are the same as the front-panel ALARM LED. The alarm relay is factory-set so that an alarm condition or the loss of unit power will cause the rear panel alarm outputs to short together (alarm relay closed). Ratings for the alarm relay and network-controlled closures are 100 Ma at 30 VDC. The two contact closures are controlled via the COMPEL command stream from the uplink. See the COMPELª Manual for the commands and structure for the relay closures.

UTY4000-003 2.6 EXPANSION CARD CONFIGURATION The purpose of this section is to detail the jumper settings and labeling instructions for the Unity Expansion Cards. For more complete explanations of setup and operation of the expansion cards, see the individual manuals which accompany the cards. 2.6.1 Balanced Audio Expansion Card 2.6.1.1 Audio Card Jumper Configuration Jumper settings Ð Dotted and Non-dotted. The headers used here have 3 pins, so a jumper connecting 2 of these pins can connect pins 1 & 2 or pins 2 & 3. The ÒNormalÓ position of this jumper is marked by a dot on the silkscreen near either pin 1 or pin 3. Dotted Position Ð Jumpering pin 2, the center pin, to the pin nearest the dot. Non-Dotted Position Ð Jumpering pin 2 to the pin furthest from the dot. Installing one audio expansion card enables audio channels 3 and 4. You should set jumpers J2, J3, J4, J6, J7, and J8 on this Audio Card to the ÒdottedÓ position. Installing a second audio expansion card enables audio channels 5 and 6. Set jumpers J2, J3, J4, J6, J7, and J8 on this Audio Card to the Ònon-dottedÓ position. Leave the jumpers on the first audio expansion card in the ÒdottedÓ position, which will continue to enable channels 3 and 4 on that card. Either available module slot may be used with the Ònon-dottedÓ card, but that card will be the Channel 5 & 6 card. The ÒdottedÓ card will be the Channel 3 & 4 card. Each card should also be labeled appropriately. (See the following section.) 2.6.1.2 Audio Card Label Instructions When a single balanced audio expansion card is installed (In either Module 1 or Module 2 slot), channels 3 and 4 are used. You should set the jumpers on that card to the ÒdottedÓ position, and label the Audio Card Bracket as [CH4 CH3]. To label it: 1. Peel the [CH4 CH3] label from the backing. xx Press the label onto the rear of the Audio Card Bracket, within the blank rectangle provided or cover existing silkscreen text. * * * Caution * * * When 2 audio expansion cards are installed, one must have the jumpers in the dotted position, and the other must have them in the non-dotted position. Failure to correctly configure the jumpers WILL cause operational problems.

Page 28 of 75

When a second balanced audio expansion card is installed, channels 5 and 6 are used. The second card is installed in the vacant module slot and connected to the first card and the motherboard by a 3-connector cable, rather than the 2-connector cable used with a single card. The second card enables Channels 5 & 6 when the jumpers are set to the ÒNon-dottedÓ position. Labeling this card is done like the first card, except it will be labeled [CH 6 CH5]. 2.6.2 SYNC or ASI Data Card Jumper Configuration When you install one SYNC or ASI expansion card, set jumper J9 on that card to the ÒdottedÓ position. See Section 2.4.1.2 for details on ÒDottedÓ and ÒNon-dottedÓ jumper positions. When installing a second SYNC or ASI expansion card, jumper J9 on that card must be set to the Ònon-dottedÓ position. Leave jumper J9 on the first data expansion card set to the dotted position. * * * Caution * * * When 2 SYNC or ASI expansion cards are installed, one must have the jumpers in the dotted position, and the other must have them in the non-dotted position. Failure to correctly configure the jumpers WILL cause operational problems.

UTY4000-003 SECTION 3 OPERATION 3.1 MODES OF OPERATION This UNITY4000 has the capability of operating as an Audio-Only Integrated Receiver Decoder. It can also receive and process video signals, but is not normally used this way. The Audio-Only capability is accomplished by setting a software flag at the factory. This being the case, unit specifications are not changed from one mode to the other, but menus and displays are presented differently from those in an Audio-Visual UNITY4000 to accommodate this duality. 3.1.1 Power Up At power up, the unit does a quick checksum test on the EEPROM. If the test passes, the unit then initializes various devices and configures itself according to the EEPROM settings. It then waits for the receiver board to complete its boot up. When the receiver board completes its boot up, the IRD sends a tune request to the receiver board and the Welcome Banner to the serial port. The IRD then enters alarm mode until all of the alarm conditions are cleared. All of this takes about 25 seconds. Also, while in power up mode, each of the Unity 4000Õs LEDÕs will FLASH (See Table 13, Page 30.). 3.1.2 Boot Fail If any of the boot fail conditions occur, the unit will enter Òboot failÓ mode. While in this mode, the unit is essentially dead. All audio and video is muted, the alarm relay is closed, the general- purpose relays are all open, and the unit does not attempt carrier acquisitions, etc. 3.1.3 Alarm, Warning, & Normal See Sections 3.2.7 (Page 31) and 3.2.8 (Page 32) for a complete list of alarm/warning conditions and for information on the LEDÕs during these modes. The overall behavior of the IRD is very similar for any of these modes, and the following is a list of their differences: • Alarm and User Relays. See Sections 3.2 (Page 30) and 3.3 (Page 32) for details. • Video is alarm frozen if No MPEG Data for less than 5 seconds, No Video for less than 5 seconds, or in fade mode for less than 10 seconds. • Video is muted for all alarm conditions except Alarming Eb/No. • Audio is muted for all alarm conditions except Alarming Eb/No and No Video Data.

Page 30 of 75

• LEDÕs are unique for each of these modes. 3.2 LED & ALARM / WARNING CONDITIONS The following definitions apply throughout this section: Table 13. LED and Alarm Conditions BLINK LED is OFF for 1 second, and then blinks on count times ( ON for 250 Ms and OFF for 250 Ms). This overall pattern is continued. FLASH ON for 100Ms, OFF for 100Ms, É FLUTTER ON for 50 Ms, OFF for 50 Ms. AMBER RED and GREEN turned ON at the same time. The UNITY4000 has eight front panel LEDÕs, each of which is described below. 3.2.1 Carrier (Green) ON if receiver board is tracking (IRD not necessarily in tracking mode). Otherwise FLASH. 3.2.2 AGC (Green) ON if RF level is OK and receiver board is tracking. FLASH if RF level is HIGH or LOW and receiver board is tracking. Otherwise OFF (receiver board is not tracking). 3.2.3 MPEG (Green) ON if synced on MPEG stream. FLASH if no MPEG sync but locked on carrier. Otherwise OFF. 3.2.4 Cue (Green) ON while any relay is closed. Also, relay must be ON for a minimum of 1 second. Otherwise, OFF. Note that the relays are often used for local audio or video insertions. It is assumed that relay 1 is momentary and starts the systemÕs insertion equipment. The actual switch is accomplished by the local commercial insertion controller. 3.2.5 COMPELª (Green) FLUTTER if COMPEL addressed to unit within last 5 seconds (keep alive commands are not considered to be addressed to unit). ON if COMPEL. received within last 2 minutes. OFF if

Page 31 of 77

UTY4000-003 COMPEL is not required or unit is not in Tracking mode. Otherwise, FLASH (unit is in Tracking and no COMPEL within last 2 minutes). 3.2.6 Authorized (Green) ON if authorized for current program and have MPEG sync. FLASH if not authorized for current program. OFF if no program is available. 3.2.7 Alarm (Red) FLASH if any of following: (See Table 13, Page 30) 1. EEPROM Boot Failure. 2. Receiver board diagnostics Boot failure. 3. Receiver board communications Boot failure. 4. Secure micro / host ID mismatch Boot failure. ON if any of the following: 1. Receiver board run-time failure. 2. Fade mode > 10 seconds. 3. Installation mode > 10 seconds. 4. Carrier table search mode. 5. Header search mode. 6. Satellite search mode. 7. Alarming Eb/No. 8. No MPEG data > 5 seconds and locked on carrier. 9. Not authorized for current program. 10. Selected program not available. 11. Failure of an optional or special output (if allowed by factory reset control mask). 12. Overheating. Otherwise, OFF When an alarm or warning condition is active, that condition is displayed on the LCD. The IRD will not indicate (neither on LEDÕs and LCD) multiple conditions; it will indicate only the most critical condition. Alarm conditions are considered more critical than warning conditions, and the list of alarm and warning conditions shown above and below are listed from most critical (#1) to least critical (#4 or #12).

Page 32 of 75

Note that the Alarm LED is only ON when the unit is either overheating or unable to produce video, or if a secondary output has failed (and if control mask allows for alarm or warning display). 3.2.8 Warning (Amber) ON if any of following: 1. E-mail received but not read. (See caution, pg 3-4, and Section Error! Reference source not found., Page Error! Bookmark not defined..) 2. Secure micro run-time failure. 3. Marginal Eb/No and locked on carrier. 4. RF level is HIGH. 5. RF level is LOW. 6. Fade or Installation mode < 10 seconds. 7. No MPEG data < 5 seconds and locked on carrier. 8. COMPEL required and no COMPEL within last 2 minutes. 9. Selected audio not available. 10. Failure of an optional or special output (if allowed by factory preset control mask). Otherwise, OFF. 3.3 RELAYS This IRD supports 1 alarm relay and 2 solid state user relays. These user relays are controlled via COMPELª and the modem/terminal interface. The following table shows the behavior of the relays for each of the modes. The sense of the alarm relay is set by an internal jumper (J17) on the unit motherboard to be either Normally Open (close on energize) or Normally Closed (Open on energize). Table 14. Relay Operation Mode Alarm Relay User Relays Normal Energized User Controlled * * * CAUTION * * * E-mail messages should be read as soon as possible after receipt, because each message will be over-written by the next one.

UTY4000-003 Warning Energized User Controlled Alarm De-energized User Controlled Boot Fail De-energized Open Power Off De-energized Open Note that the alarm relay is de-energized when the IRDÕs power is off. Power loss will look like any other alarm. 3.3.1 Pulse Command For Relay Closures A command may be issued via COMPEL which sets the state of a relay for a set time period. At the end of that time, the relay will change states. For example, Closure 1 can be commanded to close at a set time and to remain closed for a time up to 260 seconds. When the COMPEL command is received, the relay will close immediately for the set time period. At the end of that time, the relay will open. If the closure is commanded to go to a state it is already in, it will remain in that state until the time has expired, and will then change states. Up to four of these Pulse Commands can be processed simultaneously, with excess ones being ignored. Any number of Pulse Commands can be sent by COMPEL as long as no more than four are being processed at one time. 3.4 PROGRAM SELECTION Programs may be selected by network control and (if allowed by the network) by local user. A multiplexed MPEG transport stream supports a number of separate programs. Each program has several audio data streams, or a single video and several audio data streams, in the main transport stream. The programs are designated with a number, but if none is supplied by the selection command (e.g. the Ô*Õ designation), the lowest in numerical order will be selected by the IRD. There are several ways to select an audio service. This can be done from the uplink via COMPEL, or from the terminal. However, it can also be easily done via the Front Panel. Available service have had their settings loaded into a settings table at the factory. If authorized, users can scroll through these services and select the correct one. (See Table 23, Page 44, for the menu structure.) To assign a service to a Port: 1. From the Home Screen, press the Ô¯Õ key until ÒAudio SettingsÓ shows on the LCD. 2.

There are a variety of warning and advisory screens which are only shown in unusual situations. It is not possible to show all the conditions where these screens might be displayed in this table. However, these screens are shown in APPENDIX B (Page 56) along with explanations as to the conditions that generated them. 3.9.3 E-mail E-mail messages may be sent from the uplink to the Unity4000 and displayed on the LC Display. To view E-mail messages, follow these steps: 1. When an E-mail message is received, the Warning light will be turned ÒONÓand the following message will normally be shown on the LC Display: W A R N I N G :

APPENDIX A TERMINAL/MODEM COMMANDS Commands described in this section detail command syntax and action taken. Commands consist of a command field and a parameter field. Each command field and parameter field is space delimited. Optional parameters are indicated by square brackets, [ ], and conditional parameters are indicated by braces, {}. For example, COMMAND_NAME parameter1 {parameter2} [parameter3] indicates that parameter1 must be entered, parameter2 entered only when a certain condition is met (certain option is installed, etc.), and parameter3 is optional. Both commands and parameters may be entered in upper or lower case; the interface is not case-sensitive. Incorrect or incomplete commands result in ÒInvalid CommandÓ being displayed at the terminal. Parameter errors on User Commands generate ÒInvalid parameter nameÓ where parameter name is the name of the incorrectly entered parameter. A.1 STATUS COMMANDS These commands show status and help displays, but do not allow for changes to that status. A.1.1 H [command] command: Any of the terminal command names (H, R, TEMP, etc.). If an ÔHÕ or any invalid command beginning with an ÔHÕ is entered and command is omitted, the whole help screen will be displayed, consisting of a list of all available commands and a brief description of each listing. If an ÔHÕ or any invalid command beginning with an ÔHÕ is entered and command is a valid User Command Name, then detailed help for command is displayed. * * * CAUTION * * * Terminal / modem commands fall into two categories, Status Commands and Control Commands. If Local Control is disabled, only Status Commands will be accepted by the unit. No Control Commands will be accepted until Local Control is enabled. For more information, see the commands listed below.

The Audio Configurations Table entry in location (1-30) is set to service (XXX) with route (S,R,1,2) and attenuation (0-14). A.2.5 CSEL port location Select Table Entry. port: any available audio port number. location: the number of the location in the Audio Configurations Table (1-30). This command allows you to assign a table entry to a port. Its ÔnormalÕ use is to display a config. report (R CFG), and then assign one of the labeled outputs to a port. For example, to assign output ÒRockNovaÓ in table location 23 to port 2, the command is ÒCSEL 2 23.Ó A.2.6 MUTE [source][source] source: If no source is specified then video, async data, and all audios are selected. Source can be any of the following: V To indicate Video. A[/string] To indicate Audio. An ÔAÕ without the string indicates all audio outputs. The string, which has no spaces, can contain one or more individual audio outputs (1L/1R/2L/6R), one or more paired audio outputs (1/2/6), or any combination of these. Multiple outputs must be separated by forward slashes. Mutes the specified outputs. Example: MUTE V A/1L/2/4/6R, mutes the video, audio Port 1 left, Ports 2 and 4 left and right, and audio Port 6 right.

6 Ð Header Search time: Time-out value in HH:MM:SS format. Valid range up to 4660 hours (except 30 seconds for fade). Timeout.source is set to time. The timeout sources are defined as follows: (1) FADE timeout: The amount of time that the unit software will allow the receiver card to re-acquire a faded carrier Òon its ownÓ without some intervention. (2) INSTALLATION Timeout: The amount of time that the unit will attempt to initially acquire (or, after FADE timeout) re-acquire the carrier before searching for alternate carriers found in the Settings Table (called ÒCarrier SearchÓ mode). (3) CARRIER SEARCH: The amount of time the unit will remain in CARRIER SEARCH before attempting SATELLITE SEARCH mode [not defined currently]. (4) NO COMPEL: The amount of time the unit will remain parked on a carrier after it has last received a valid COMPEL network header before attempting to re-acquire carriers in its Settings Table to see if they carry valid COMPEL network traffic (called HEADER SEARCH mode). This is only applicable to IRDs whose COMPEL REQUIRED status is REQUIRED. (5) HEADER SEEK: The amount of time a unit in HEADER SEARCH mode will loiter on a carrier it has acquired awaiting valid COMPEL pack headers before proceeding to attempt the same on other carriers in the Settings Table. If it acquires a valid COMPEL header, it reverts ot TRACKING mode. (6) HEADER SEARCH: The amount of time the unit will remain in HEADER SEARCH before attempting SATELLITE SEARCH mode [not defined currently]. A.2.16 SNR alarm_level margin_offset alarm_level: Units of Db with range from 5.0 Ð 14.9 and can have one decimal place. margin_offset: Units of Db with range from 1.0 Ð 10.0 and can have one decimal place. Sets alarm_level and margin_offset accordingly. A.2.17 TEMP settings time settings: See Perms/Temps/Searching & Settings Section. time: Length of insert in HH:MM:SS format. Valid range is 00:00:00 to 18:00:00. Will handle data rate rounding as explained for PERM. Unit sets its temp_settings to settings. See Perms/Temps/Searching & Settings Section for more information. A.2.18 TEMPCH location time location: Value from 1 Ð 48 indicating location in settings_table. time: Same as for TEMP. Unit sets it temp_settings to those retrieved from the settings_table according to location. A.2.19 UNMUTE [source][source] source: Same as the MUTE command. Identical to MUTE except specified services are unmuted.

APPENDIX C GLOSSARY OF TERMS AMBER - An LED with the red and green both ÒOn.Ó ASIC Ð Application-specific Integrated Circuit: A general term for any highly integrated circuit (in a single package that historically very complex operations solders to a printed-circuit-board) implementing. BLINK - An LED which is ON for 250 Ms and OFF for 250 Ms, with the pattern continuing for some time, is said to ÒBlink.Ó See Table 13, Page 30. Also, see ÒFlashÓ and ÒFlutter.Ó CAUTION Ð A highlighted statement ÒcautioningÓ the reader to use care so the equipment does not malfunction or cause a problem such as program outage. (See ÒWarningÓ) COMPELª - WegenerÕs patented satellite network control system. This is a system which features a control data stream embedded along with the payload services, where a single central control site may control all aspects of network operation: database management, program selection and setup by site, grouping of sites, scheduling, etc. DAC - Digital-to-Analog Converter. A device that converts a sequence of numbers representing signal amplitudes in electronic binary format to actual analog signals. EEPROM Ð Electrically-Erasable Programmable Read-Only Memory. This acronym is used to describe any non-volatile memory device which can be read- or written-to a nearly unlimited number of times, but which retains its last written data when power is turned off. FEC Ð Concatenated FEC: Forward Error Correction. A method of mapping digital data for transmission over a noisy, error-creating medium, and then un-mapping it, such that error-reduction is achieved. This allows for lower-power (but wider bandwidth) carriers to be used than would otherwise be required on a satellite link. Concatenated FEC means that a bit-level convolutional FEC is embedded ÒinsideÓ a byte or frame-level Reed-Solomon FEC within the transmission path. This is done to create a far more powerful error-reduction system than either type of FEC alone could provide. FLASH Ð An LED which is ON for 100 Ms and OFF for 100 Ms, with the pattern continuing for some time, is said to ÒFlash.Ó See Table 13, Page 30. Also, see ÒBlinkÓ and ÒFlutter.Ó

Page 75 of 77

UTY4000-003 FLUTTER Ð An LED that is ON for 50 Ms and OFF for 50 Ms, with the pattern continuing for some time, is said to ÒFlutter.Ó See Table 13, Page 30. Also, see ÒBlinkÓ and ÒFlash.Ó MCPC Ð Multiple-Channel-Per-Carrier. Means that one or more services or programs are present on a particular radio-frequency carrier. NTSC Ð National Television Standards Committee. This is a shorthand description for the standard 525-line, 30-frames-per-second analog baseband television signal format used in the US MPEG, MPEG Transport Stream Ð Moving Picture Experts Group. This catchall abbreviation is used to describe the digital compression (redundancy reduction) of linearly-digitized audio and video signals as well as the mode of multiplexing and transporting that compressed data. The Transport stream is a packetized system consisting of a sequence of 188-byte packets, each with a sync-byte and a specific payload identified by a payload ID (or PID). The stream contains packets not only for the compressed audio and video, but also auxiliary data, program information and allocation data, and conditional access information. PID Ð Payload Identifier (or ID). See ÒMPEG.Ó PROGRAM Ð A single video channel and associated audio signals. QPSK - Quadrature Phase Shift Keying. This is a popular mode of transmitting digital information by varying the phase of a radio-frequency carrier. SCPC Ð Single-Channel-Per-Carrier. Only one service or program is present on a particular radio-frequency carrier. SETTINGS TABLE Ð An internal table of alternate carrier/program settings stored in the IRDs non-volatile memory (remembered through power cycles). This table may be used in the following ways: (1) If an IRD is unable to acquire the commanded carrier, then it will, after an appropriate time-delay, search for and lock onto any carriers in the table it may be able to find. (2) If local control is enabled, a user may, through the front-panel or terminal command, tune the IRD to a new setting found in the table using the shorthand of the Settings Table entry number. WARNING Ð A highlighted statement ÒwarningÓ the reader to use care so the equipment is not damaged, or a person injured. (See ÒCautionÓ)
