1.2 Unity 550 Product Overview
Digital
Television
Receiver
The Unity 550 Digital Television Receiver is a high-performance satellite Integrated
Receiver-Decoder (IRD) designed to meet the needs of the private television market-place.
Supporting both the PAL and NTSC video standards, the Unity 550 is uniquely positioned to
provide high-quality video, audio, and data to demanding customers. The Unity 550
supports DVB World Standard Teletext and Line 21 Closed Captioning and Extended Data
for enhanced video functionality.
Multiple data features are standard to provide additional ways to use spare digital spectrum
for revenue and operational control. A 38.4-kbps asynchronous output provides constant
streaming of control and user information. This data port is used for local and remote
diagnostics, COMPEL™ data delivery services, and auxiliary data. Using COMPEL, the data
output can control external devices, such as collection encoding systems and video
switching equipment. COMPEL is able to command the serial number to be displayed on
screen for asset protection.

Do not open the Unity 550's chassis cover.
The Unity 550 incorporates security labels over some of the screws. There are no user
serviceable components within the IRD. Tampering with the security labels, or opening the
unit, will void your warranty. If you have questions, contact the Wegener Customer Support
Department at the address or phone (fax) numbers listed in Chapter 5 Customer Service,
of this manual.

CHAPTER 2 INSTALLATION
This chapter provides instructions on unpacking, mounting, and connecting your Unity 550
as well as connector information including detailed pinouts.
2.1 Unpacking and Inspection
Carefully unpack the unit and its ac power cord and inspect 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.
Note: Please save the packing materials and original shipping containers in case you
must later return the unit for repair. Packing these units in other containers in such a
way that they are damaged will void your warranty.
2.2 Location and Mounting
The Unity 550 may be mounted in a standard 19-inch equipment rack or set up for desktop
operation. In either location, maintain a clean, dry environment for the Unity 550.
Precautions FCC-Mandated Suppression of Radio Frequency Emissions
WARNING This is a Class A product. In a domestic environment this product may cause radio
interference for which the user may need to take mitigating action.
If the Ethernet port has a cable connected to it, that cable must be properly shielded and
grounded to minimize RF emissions that could interfere with nearby equipment.
DANGER To avoid damage to the Unity 550 unit and other equipment, or personal injury, the following
items should be strictly observed.
Elevated Ambient Operating Temperatures in Rack-Mounted Units
When equipment is installed in a closed or multi-unit rack assembly, the ambient operating
temperature of the rack environment may be greater than the room's ambient temperature.
Therefore, consideration should be given to the ambient air temperature within the rack (not
just inside the room) when deciding if the maximum recommended ambient operating
temperature (TMRA) is met or exceeded.
Reduced Air Flow
Equipment should be installed such that the airflow required for safe operation of the
equipment is not compromised. The Unity 550 may be arranged in a rack without empty
spaces between units, if heat buildup is prevented by ensuring that the side vents remain
unblocked, and that there is adequate clearance around the vent holes.
Mechanical Loading
Rack-mounted equipment should be installed in such a way that a hazardous condition is
not produced by uneven loading. The Unity 550 unit is not very heavy, but total rack loading
must be considered. Also, do not rest any unsupported equipment on a rack-mounted Unity
550 unit.

Circuit Overloading
Consideration should be given to the connection of the equipment to the supply circuit and
the effect that overloading of circuits could have on overcurrent protection and supply
wiring. Ensure that the total rack or breaker power consumption does not exceed the limits
of the AC branch circuit. Appropriate consideration of equipment ratings should be used
when addressing this concern.
Reliable Earthing
When connecting the Unity 550 unit to the power supply, review the ratings of all equipment
in the circuit to ensure that the branch circuit, as well as the power source, will not be
overloaded. Also make sure that the unit is properly grounded and/or that a protected power
strip is used to attach it to the power supply
Rack Mounting
The Unity 550 unit should be installed in such a way that a half-inch clearance is allowed on
each side and a quarter-inch on the top to ensure adequate air flow. Ensure that a
hazardous condition is not produced by uneven loading, or by resting any unsupported
equipment on a rack-mounted Unity 550 unit.
Parts for the Unity 550 unit include 2 angle rack mount brackets and 4 rubber feet. For rack
mounting, do not attach the rubber feet as they interfere with the rack mounting.
1. Remove the 2 screws from the left and right sides of the unit.
2. Insert the angle brackets into the left and right sides of the unit ensuring that the screw
holes for the unit and brackets are aligned.
3. Secure the brackets by re-inserting the screws through the brackets and unit.
4. Install the unit onto the rack.
Note: The front brackets must be secured to the rack. If the front brackets are left
unsecured, the unit may shift forward and fall from the rack, and may result in
personal injury and/or damage to the equipment. The internal temperature of the
rack should not exceed 40oC.
Desktop Installation
Parts for the Unity 550 unit include 2 angle rack mount brackets and 4 rubber feet. For
desktop installation, do not attach the brackets.
1. Attach the 4 rubber feet onto the indented areas at the bottom of the unit.
2. Place the unit on a flat surface where it will not be subject to spills or impacts.
3. Route cables to the unit so that they will not be hit or pulled, causing damage to the
connectors or to the unit itself. Ensure a sufficient flow of cool air so that the unit's
operating ambient temperature range is not exceeded.

CHAPTER 3 OPERATION
This chapter provides information and procedures for powering up and operating the unit.
The IRD can be controlled via COMPEL, local terminal, modem (remote terminal), and OSD
(On-Screen-Display) push buttons. Normally, COMPEL is the primary method of controlling
the IRD, while the other control methods are supplemental. See COMPEL™ System Control
on page 18 for more information, and the COMPEL Manual for a complete explanation of
COMPEL controls.
3.1 Front Panel Controls And Indicators
Figure 3.1 shows the Unity 550 front panel controls and describes them in Table 3.1. The
IRD can be controlled via COMPEL Network Control, local terminal, modem (remote
terminal) and OSD push buttons. Normally, COMPEL is the primary method of controlling
the IRD, while the other control methods are supplemental.

3.2 LED Status and Alarm/Warning Conditions
The Unity 550 unit's only LED is Red/Green, located on the front panel, and labeled Status.
Table 3.2, lists the behavior of the Status LED during Power Up and Normal operation, as
well as the color and blink/flutter pattern shown during various Warning and Alarm
conditions.
The conditions are listed in the order of their display priority with highest priority at the top.
Note: The alarm conditions are those conditions preventing the delivery of video.
LED
definitions The following definitions of Amber, Flash, Blink, and Flutter explain the terms used in the
Status LED Display column of Table 3.2 on page 15.
Amber Red and Green turned ON at the same time.
Flash ON for 100 ms, OFF for 100 ms.
Flutter ON for 50 ms, OFF for 50 ms.
Blink LED is OFF for 1 second, then blinks ON for 250 ms and OFF for
250 ms between 1 and 12 times, according to the Alarm/Warning

pattern continues until the alarm/warning condition is cleared. (For
example, if the unit is displaying a "header search mode" alarm, the
LED will be OFF for 1 sec., then will blink (RED) ON for 250 ms and
OFF for 250 ms five times. It will then be OFF for 1 sec., followed
