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 10-40
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-to­analog 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.

5/6 1.63-30 Msps 2.5-46.078 Mbps 6.0

7/8 1.55-30 Msps 2.5-48.382 Mbps 6.4

2.3.3 Transport DEMUX

The transport demux is used to extract the desired video and audio streams from the multiplexed
data stream.

2.3.4 System Processor

The main system processor is an extended architecture processor, and uses flash memory for
microcode storage with download capability via either terminal or satellite channel.

The unit also has an MPEG2 video processor ASIC, and an audio processor ASIC.

2.3.5 Auxiliary Data Processing

An asynchronous user-data stream embedded in the transport stream may be routed to SERIAL
1 or SERIAL 2 ports under user or network control. The controller need merely supply the PID
of the MPEG packets bearing the data and the output baud rate.

2.3.6 Composite Video Encoder

The IRD supports the video resolutions given in Table 4. The unit automatically senses the
format (NTSC or PAL) and reconfigures the video decompression system accordingly.

2.3.10 Encryption

The WCI decryption option includes a secure microprocessor and a decryption ASIC. Different
levels of security may be implemented with software and ASIC changes.

2.3.11 Transport Output

The TRANSPORT output supplies the original received MPEG2 transport stream in
Synchronous Parallel format.

2.3.12 Option Modules for Expansion Ports

The IRD has two expansion slots Ð one high speed and one low speed. The high speed
expansion port provides the transport layer multiplexed stream while the low speed expansion

port provides the filtered packet data. An I

2

C bus provides control for option modules. The

specifications for individual modules are included in documentation for the module.

2.3.13 AC Power

The unit features a universal-input power supply. AC line is fed into a standard IEC jack. The
nominal inputs are 115 or 230 VAC ± 10% at 50-60 Hz ± 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.

UTY4000-011 Page 20 of 75

No user-accessible controls or indicators are located on the module.

2.5.1 Balanced Audio Outputs

There are two audio channel outputs on the 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 user­controlled 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 screw­terminal strip as possible. If minimal slack is used in the outer Òturn,Ó the ferrite core

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.

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.

* * * 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.

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.

Page 27 of 77 UTY4000-003

Page 28

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

* * * 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.

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.

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 general­purpose 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
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:

(Page 32) for a complete list of alarm/warning conditions

• 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 29 of 77 UTY4000-003

Page 30

• LEDÕs are unique for each of these modes.

3.2 LED & ALARM / WARNING CONDITIONS

The following definitions apply throughout this section:

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

FLUTTER

ON for 100Ms, OFF for 100Ms, É

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

UTY4000-011 Page 30 of 75

Page 31

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 31 of 77 UTY4000-003

Page 32

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.

* * * CAUTION * * *

E-mail messages should be read as soon as possible after receipt, because each message will

be over-written by the next one.

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).

Mode Alarm Relay User Relays

Normal Energized User Controlled

UTY4000-011 Page 32 of 75

Table 14. Relay Operation

Page 33

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. Press <SELECT> and the LCD screen ÒPRESET SELECT: / PORT 1:Ó will appear.

3. Press <SELECT> again to enable field editing, or press Ô¯Õ to move to the other
available port screens. Press <SELECT> when the desired port screen appears.

Page 33 of 77 UTY4000-003

Page 34

4. Then press the ÔÕÕ or Ô®Õ key several times to scroll through the available services.

5. Press <ENTER> to set the Port to the currently displayed service.

The audio settings discussed above are contained in an Audio Configurations Table, which is
factory set in an EEPROM. These labels are a local ÒshortcutÓ to allow quick selection of audio
programs. When selected, these labels configure the unit for a particular service, routing, and
attenuation level. The Audio Configurations Table may be set or changed using a terminal and
the Terminal Commands. See APPENDIX A (Page 50) for an explanation of Terminal
Commands.

3.4.1 Duplicating Audio Service

You may not set one service or audio-route to be received on multiple audio ports. Trying to do
this will result in the display of a Front Panel screen such as the one below.

s s s : S e r v I c e U s e d o n

P o r t X : m m m m m m m m m m m m m

Where sss is the name of the audio service being duplicated, and x is the port that is currently
using the service.

mmmmmmmmmmmmm is a message prompting the user as to the action to take. This may be
ÒMove to PortYÓ where Y is the port the service was requested on (This will MOVE the service
to Port Y.). The other option is ÒCancelÓ which will cancel the previous command. The
Up/Down arrow keys will change the option; pressing <ENTER> will execute the currently
displayed option.

3.5 AUDIO HANDLING

The selected program (See Section 3.4) has a number of separate compressed-audio data streams
associated with it. These are assigned 3-letter mnemonic designations. Any of these may be
routed to either the Ch1 or Ch2 stereo outputs on the back of the IRD (but not both!). The
selected stream is a stereo or dual-mono signal. It may be routed to the L and R connections in a
specific relationship to the original audio connections at the uplink MPEG encoder unit:

Table 15. Audio Handling

Stereo Original encoder L and R routed to corresponding L and R outputs on

IRD

Reverse Stereo Original encoder L routes to IRD R output, while original R routes to

the L output

1 on both* Original encoder L is routed to both L and R outputs on IRD

2 on both* Original encoder R is routed to both L and R outputs on IRD

UTY4000-011 Page 34 of 75

Page 35

* Originally, left ÒchannelsÓ were designated Ò1Ó and right as Ò2Ó. Now ÒchannelÓ designates
the selected audio program by PID.

3.6 UNIT CONTROL

The IRD can be controlled via COMPELª, terminal, modem, DIP switches, and Display / Push
buttons. Each of these methods of control is explained in the following sections, but you should
read the COMPEL manual for a complete explanation of the COMPEL system.

3.6.1 COMPELª

The COMPEL command stream from the uplink is usually the unitÕs primary source of control.
This asynchronous stream is muxÕed into the aggregate MPEG data stream at the uplink. An
IRD can also accept a local COMPEL command stream from its serial port if enabled by the
satellite program provider. However, it can only process one of these streams at any given time.
See the COMPEL Manual for a complete explanation of the COMPEL system.

3.6.2 Terminal

The terminal command interface can be accessed by setting serial port 2 ÒdeviceÓ to ÒTerminalÓ
(using front panel control). You may then access the terminal commands if you have a terminal
installed. These commands appear on a help screen and are documented in APPENDIX A of this
manual. With the exception of the ÒRÓ and ÒHÓ commands, they are only available if local
control is enabled. See APPENDIX A (Page 50) Terminal/Modem Commands, for a full list of
Terminal Commands, and their explanations.

3.6.3 Modem

The modem command interface is similar to the terminal interface. That is, it does not utilize
special handshaking or special control characters for this interface, and only supports auto­answer modems. In fact, the IRD does not distinguish between an attached terminal and a
modem. To access the modem command interface, the serial port 2 ÒdeviceÓ must be set to
ÒModemÓ (using front panel control). To access user commands, the user must enter the correct
password at the prompt. The user then retains access until (1) the ÒOHÓ command is received,
or (2) 10 minutes passes with no user input. As is the case for the terminal, the user commands
are restricted when local control is disabled. See APPENDIX A (Page 50), for a full list of
Terminal Commands and their explanations.

3.6.4 Dip Switches

The use of the four DIP switches is shown in the following table:

Dip Switch Function (UP is the most common state.)

Table 16. Dip Switch Function

1 NTSC Ð UP. PAL Ð DOWN

2 Reserved

3 Test Mode. UP:INACTIVE, DOWN:ACTIVE. While in test mode, the unit

pulses 831 Hz tones out each audio output. The tones are ON for 1 second,
OFF for 1 second, É. Also, a gray scale is output for video.

4 LNB Power. UP: OFF, DOWN: ON. Not under software control.

3.6.5 Display / Push Buttons

This interface supports the following functions:

1. Status.

2. Control.

3. Front panel E-mail.

See Section 3.9 (Page 41

) and APPENDIX B (Page 56) for more information on the Front Panel

controls and LCD menus.

3.7 SERIAL PORTS

The UNITY4000 contains two serial ports. Any of four ÒdevicesÓ may be assigned to either
serial port, though higher-speed processes should prefer port 1 because it has more buffering.
Also, any device may only be assigned once, with the additional restriction that if either the
terminal or modem is assigned, the other cannot. Communication is fixed at 1 stop bit and 8 data
bits, and there is no handshaking. The serial portÕs behavior for each of its device types is shown
in the following table.

Table 17. Serial Device Settings

Device Serial Port Behavior

Printer Configured to B, P, 8, 1 (See note 1). All input data is ignored.

Aux Data Configured to B, P, 8, 1 (See note 2). All input data is ignored.

Terminal Configured to 19200, N, 8, 1. The unit responds to the terminal/modem commands as

described in Appendix A.

Modem Configured to B, N, 8, 1 (See note 3). The unit responds to the terminal/modem

commands as described in Appendix A.

Note 1. For Printer: ÔBÕ may be 1200, 2400, 4800, 9600, or 19.2k baud; ÔPÕ may be ÔOÕ for Odd, ÔEÕ for

Even, or ÔNÕ for No parity.

Note 2. For Aux Data: ÔBÕ may be 1200, 2400, 4800, 9600, 19.2k, or 38.4k baud. ÔPÕ may be ÔOÕ for

Odd, ÔEÕ for Even, or ÔNÕ for No parity.

Note 3. For Modem: ÔBÕ may be 9600, or 19.2k baud; parity is always ÔNÕ for No parity.

UTY4000-011 Page 36 of 75

Page 37

3.7.1 Printer Device Handling

For the Printer device, there are three legal output types: COMPEL E-mail, COMPEL
Requested Reports, and Raw COMPEL (binary) data. If allowed, then the uplink, through
COMPEL, may elect to send E-mail or request report dumps. (See the COMPEL Manual about
COMPEL E-mail.) The report dumps are the same as those the local user may select using the
ÔRÕ terminal commands. This causes the literal COMPEL data stream to be output on the
assigned serial port. (Note that this will include non-printing characters!)

3.7.2 Aux Data Device

This device is defined to allow for async data streams to be carried within the Transport stream
and their raw payloads output on an IRD serial port. The PID of these streams may or may not
be assigned to a Service within a PMT. To recover the data, the IRD need only be given the PID
and baud-rate. This may be done through COMPEL command, or by the local user. Local users,
if allowed by the ÔLocal Control EnableÕ setting, uses the AUXDATA terminal command or the
Aux Data submenu under Hardware Setup/Serial Ports in the front-panel LCD control screens.

3.8 RECEIVER FUNCTIONS

Note that throughout this manual, the term valid carrier means the absolute value of the difference
between the LNB LO and the carrier is > 950 MHz and <

2150 MHz.

3.8.1 Perms, Temps, Searching & Settings

The term settings is used throughout this document and includes the following parameters:

Table 18. Settings Parameters

{RF_In} Value from 1 Ð 4, specifying the RF input (if RF Switch is installed)

Carrier The downlink frequency specified in MHz with up to two decimal places.

This valueÕs absolute difference with the LNB LO frequency must be ≥ 950
MHz and ≤ 1450 MHz.

Data_rate The data_rate is the MPEG2 transport rate in Mbps. (See Table 3, Page 17,

for allowed ranges.) This figure can have up to three decimal places.

Fec_rate The inner FEC code ratio, which can have one of the following values: _, 2/3,

_, 5/6, or 7/8.

Tag_site Value of 0-14 specifying the location of this carrierÕs tag frequency. See

Section 3.8.4 ( Page 40) for special note on the use of Tag Site 15 to disable
the requirement for Carrier ID Tags.

[program] The program number from the MPEG Program Association Table. This must

be a number from 1 to 65535. If omitted or an Ô*Õ is entered, the unit will
select the first available program stream. Note that this number points to the
PID for the Program Map Table for what we might call a ÒserviceÓ (a single

video channel and associated audio signals).

The IRD is acting on one of three groups of settings at any given time, each of which is described
in the following table:

UTY4000-011 Page 38 of 75

Table 19. Settings Types

Page 39

Temp These settings are entered via COMPEL or the TEMP / TEMPCH terminal

Perm The perm_settings are entered via COMPEL or the PERM / PERMCH

Description

commands. The unit is said to be inserting when it is configured to the
temp_settings. The maximum length of an insert is approximately 18 hours
(65535 seconds). An insert terminates when (1) it times out, (2) an ABORT
command is received, (3) power is cycled, or (4) an invalid header is seen. Any
Temp commands received while the receiver is currently inserting are ignored.
If a Perm command is received while inserting, the perm_settings are updated
but not acted on until the insert is terminated.

commands, OSD interface, or automatically from within a search mode (see
below). The perm_settings are the only settings group that are stored in
NVRAM.

Satellite Search modes. When the unit finds what it is looking for in the search
mode, it copies the search_settings to the perm_settings. These are then
considered to be the active settings.

3.8.2 Settings Table (or Search Table)

This is an internal database retained in nonvolatile memory (NVRAM) which contains a list of
alternate carrier settings. Each valid entry is a complete description of a carrier/program setting
(as used in a PERM command). This list is entered at customer request at the factory, and may
be edited using COMPEL commands or ADDS and DELS terminal commands. The entries are
referred to as Òtable entriesÓ or Òsearch settings entries,Ó etc. The Settings Table is typically
used for one of two possible operations: (1) As a shorthand way for a local user to preprogram
particular carrier/program combinations and quickly tune the IRD to them; or (2) as a source of
alternate fallback carriers in the event that the ÒnormalÓ carrier is lost (or has a failure in its
COMPEL stream). The Carrier and Header Search IRD modes are examples of this second
operation.

Page 39 of 77 UTY4000-003

Page 40

3.8.3 Signal Quality Monitoring

The IRD provides the following signal quality information:

Table 20. IRD Signal Quality

Eb/No An average Eb/No reading. An Eb/No is taken approximately every 500 Ms,

and the Average Eb/No is a 10 second running average of these readings.
Display of Eb/No is based on readings from the OEM DVB receiver
daughtercard.

The Eb/No alarm is generated when the average Eb/No is found to be lower
than the ÒSNR Alarm Level.Ó A margin warning is generated when the
average Eb/No is not yet low enough to be in full alarm, but it fails to exceed
that alarm threshold by the ÒMargin OffsetÓ (in Db).

RF Level Unit will show WARNING if the RF level is detected to be above Ð20 dBm or

below Ð60 dBm.
Signal Fades A counter is maintained for transitions from Tracking to Fade mode.
RF Glitches A counter is maintained for carrier ÒhitsÓ. A ÒhitÓ is when the receiver board

detects one or more uncorrectable Reed-Solomon frames, yet small enough

not to cause a transition from Tracking to Fade mode. Note that an RF hit

will induce a hit on the unitÕs video/audio.
Availability Shows the percentage of time that the unit has been locked on a carrier since

that carrier was first acquired.

3.8.4 Frequency Tagging

Under normal operation, the IRD can only acquire carriers that contain frequency tags
(EXCEPTION: See next subsection.). These tags are inserted in the COMPEL control stream at
the uplink and are used for identifying the carrierÕs frequency. Tagging was mandated, because
without them, the IRDs could have locked on some other, nearby, (adjacent) carrier while looking
for the intended carrier. The tuning can be off by several MHz, which is due to minor offsets in
the LNB and within the receiver itself. Traditionally, the tags have been sent at a rate of every
100 or 125 Ms. The IRD supports both single and multiple tags. The tag_site, which is part of
the settings, tells the receiver which of these possible tags to use. An exception to that Protocol
is that this IRD only allows for Tag Site designations from Ô0 to 15Õ inclusive, and Ô15Õ is
specially reserved (see next). To reduce processing overhead, the unit only looks for tags while
in the Get Tag sub-mode or when tag_testing. The IRD does not provide an indication of time­since-last-tag.

UTY4000-011 Page 40 of 75

Page 41

Exceptions to the normal operation with respect to Carrier ID Tagging are:

xx If the IRD is in the nonvolatile ÔISOG EÕ state (see ÔISOGÕ terminal command),

the Carrier Tags are not required. When in the GET CARRIER submode, and
Carrier Lock is achieved, then the unit state transitions directly to TRACKING
(passes through GET TAG).

xx If the Carrier Setting shows Tag Site Ô15Õ, then that is treated as an ÔISOG EÕ command

which is only effective as long as the IRD remains tuned to that Carrier Setting.

3.9 DISPLAY / PUSH BUTTONS

3.9.1 Overview

The front panel consists of a 2 X 20 Display and six push buttons. Essentially all control
available through the terminal is available via the front panel. The front panel can also be used to
view a COMPEL down-loadable text message. This message is volatile and can contain up to 512
characters. The Display can be in one of the following modes:

Table 21. Display Modes

Mode Description

HOME Display shows ALARM or WARNING message (if applicable), or RF

switch position, carrier frequency, program ID and TEMP (if inserting).
Display returns to this screen after push buttons are inactive for 5
minutes or if both ENTER and SELECT buttons are pressed

simultaneously.

SN Unit Serial Number displayed for two seconds if ENTER is pressed while

in HOME screen.

MENU Entered from Home mode. Display shows menu for each available

command group.

PARAMETER Entered from Menu mode. Display shows specific parameter associated

The table above lists screens shown in normal operation. 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

To view

E-mail

messages may be sent from the uplink to the Unity4000 and displayed on the LC Display.

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:

APPENDIX A

TERMINAL/MODEM COMMANDS

* * * 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.

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.

UTY4000-011 Page 50 of 75

Page 51

A.1.2 R type [page]

type: Indicates the type of report as follows:

C - Carrier Status
CFG Ð Configurations Table
P - Parameters
G - Group Status
NC - Network Controller Status
M - MPEG
R - Relay Status
S - Settings Status
ST - Settings Table
SP - Serial Port Configuration

[page]: This option can have a value of 1 to 8 and is only applicable for the group status report.
Indicates the page to be reported. If omitted, all eight pages are reported and scrolls off the
terminal screen.

A.2 CONTROL COMMANDS

Again, these commands are only active when ÒLocal ControlÓ is enabled. They are the
commands by which you may change unit settings.

A.2.1 ABORT

Insert is terminated.

A.2.2 ADDS location settings

location: Value from 1 Ð 48 indicating location in settings_table.

settings: See Perms/Temps/Searching & Settings Section.

The settings are added to the settings_table at the specified location. Will also handle data rate rounding as
explained for PERM.

A.2.3 DELS location

location: Value from 1 Ð 48 indicating location in settings_table.

The entry in the settings_table at the specified location is deleted. Ignored if only one entry in
settings_table.

A.2.4 CADD location route service attenuation

Set Audio Configurations Table Entry.

location: Value from 1-30 indicating location in the Audio Configuration Table.

route: S-Stereo, R-Reverse Stereo, 1-Ch1 on both, 2-Ch2 on both.

service: Three-letter audio service.

Page 51 of 77 UTY4000-003

Page 52

attenuation: 0-14 Db attenuation level

.

This command assigns a ÔLabelÕ to an audio configuration and places that label and configuration
into the Audio Configurations Table. 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.

A.2.7 OH

(Modem control only) When in a terminal control session via a modem, this discontinues user
(password-authorized) access.

A.2.8 PC device baud parity

device: P or M, for Printer or Modem, respectively

baud: 9600 or 19200.

See Section 3.7 for details.

A.2.9 PERM settings

settings: See Section 3.8.1.

Unit sets its perm_settings to settings. See Section 3.8.1 for more information.

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
continuing for some time, is said to ÒFlash.Ó See Table 13, Page 30. Also, see ÒBlinkÓ
and ÒFlutter.Ó

, with the pattern

UTY4000-011 Page 74 of 75

Page 75

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)
