Chapter 2. INSTALLATION
This chapter provides instructions on unpacking, mounting, and connecting your U500 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 U500 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 U500.
2.2.1. 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 U500 unit and other equipment, or personal injury, the following
items should be strictly observed.
2.2.1.1. 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.
2.2.1.2. Reduced Air Flow
Equipment should be installed such that the airflow required for safe operation of the
equipment is not compromised. The U500 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.
2.2.1.3. Mechanical Loading
Rack-mounted equipment should be installed in such a way that a hazardous condition is
not produced by uneven loading. The U500 unit is not very heavy, but total rack loading
must be considered. Also, do not rest any unsupported equipment on a rack-mounted
U500 unit.

UNITY 500 USER’S MANUAL
800001-01 Rev. E 8www.wegener.com
2.2.1.4. 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.
2.2.1.5. Reliable Earthing
Reliable earthing of rack-mounted equipment should be maintained. Particular attention
should be given to supply connections other than direct connections to the branch circuit
(use of power strips, chassis ground lugs, etc.).
2.2.2. Rack Mounting
The U500 is sized as a single RU and will fit an EIA-standard, 19-inch-wide equipment
rack.
First install angle brackets or cross-supports capable of supporting both the unit and its
connecting cables. Screw or bolt the supports securely to the equipment rack.
Place the U500 on its supports and use four anchor screws or bolts and nuts to secure
the U500 front brackets to the rack.
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 during installation or operation. Failure to
secure the front brackets may result in personal injury and/or damage to the equipment.
2.2.3. Desktop Installation
To set up the U500 in a desktop environment, place the U500 on a flat surface where it
will not be subject to spills or impacts. Also 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 temperaturerange is not exceeded.
(See 2.2.1.2, Reduced Air Flow, on page 11.)
Locate the U500 and its cables to avoid impacts, spills, and pulling cables and to ensure
sufficient air flow. Failure to locate the U500 in a proper environment may result in
damage to the equipment.

3.4. Power-On Procedure
Apply power to the IRD. The unit initializes various devices and configures itself
according to the EEPROM settings. It then waits for the receiver section to complete its
power up test, which takes about 10 seconds.
When the receiver section passes its test, the IRD sends a tune command and the
Welcome Banner screen to the serial port.(An example is shown in Figure 3.2 below.) If
the unit is in Terminal mode, the banner displays on the terminal screen. The IRD then
enters Alarm mode until all of the alarm conditions are cleared.
Figure 3.2: Unity 500 Terminal Welcome Banner Screen
Your banner may be different from this example depending on the options purchased.
NOTE: The “Type H…” text at the bottom of the screen is shown only if the serial device
is set to Terminal mode.
3.5. On-Screen Network E-mail
The network may, through the COMPEL network control system, send e-mail messages to
the video (OSD) screen. The content, location, and duration of the messages are
essentially under the control of the network. The local user may neither move nor scroll
through the messages. If necessary, a message may be cleared by the local user by:
1. Either power-cycling the unit,
2. Or pressing the SELECT button on the front panel to get a local control menu and
then exiting out of that menu.
[See Section 3.7.2 On-Screen Display (OSD) Settings on page 21.]
3.6. On-Screen Display (OSD)
The OSD information is contained in a 14-line x 40-character display in the video output
from the receiver. This output is viewed on a monitor connected to the video monitor
output of the receiver. Turn it on by pressing either the SELECT or ENTER push-button on
the front panel. Remove the display by selecting EXIT from the Main Menu. When a
menu is first shown, the cursor is always placed on its first action field (or action-with-edit
field, whichever is first).
The OSD provides the following:
1. Carrier Status,
2. Signal Strength Monitoring,
3. Serial Port device selection,

3.7. Customizing and Viewing Settings for Your System
Though the Unity 500 is set up at the factory, you can customize its settings to fit your
system using the OSD and front-panel push buttons. You may also view those settings
and various status and version fields from the front panel, viewing on a monitor.
Note: The screens shown in Section 3.7 contain only sample data. The actual data for
normal operation will differ due to settings differences for each network or unit.
3.7.1. COMPEL™ System Control
The Unity 500 IRD is most often controlled via the Wegener COMPEL Control System. This
system is managed at the uplink site, sending a control stream with the usual audio and
video data streams. The COMPEL System addresses units, and commands them to
perform various functions.
Among its functions is the ability to enable or limit aspects of local control. (See the
following section for more on this capability.) Also, COMPEL has the ability to mute the
audio and video of an IRD if it is inadvertently tuned to a frequency it is not authorized to
receive.
If an RF Switch option module is installed, COMPEL will control which of the four RF feeds
is being processed. For more information on this, see the COMPEL Manual, or contact
your service provider.
