ABOUT THIS MANUAL
This manual was composed in Microsoft Word 97, and is configured to be used most easily as an
electronic document. It can be printed and used as a hard copy, but some features, such as links,
are not accessible in that mode.
If viewing the electronic version, we recommend you safeguard the original to avoid the effects
of somehow altering your master copy.
Cross-references
Cross-references are internally linked for easy access. If you are viewing the electronic version
of this manual, and see text that is blue and underlined, such as (Record of Revisions) you can
“click” your mouse on that text and “link” to that section.
When you are ready to return to the previous section, “click” on the web toolbar “back” arrow
and return. The web toolbar should appear automatically when you use a link, but if it does not
you can invoke it from Toolbars on the View menu.
Because many users will print the manual, we have also included the page numbers for most
links.
Table of contents
You can also link from the Table of Contents to any listed page. This also applies to the List of
Tables and List of Illustrations. Just “click” on the page numberfor any section, table, etc., you
want to move to. Return to the Table of Contents as described in the “Cross-references” Section
above.
Other Viewing Methods
In the electronic version, there are several methods of moving about a document. “Clicking”
Document Map or Online Layout on the View menu will open a window showing the document
outline. This is similar to the Table of Contents, and will allow you to move about the document
by “clicking” on a section. It has the advantage of not going away when you move to another
section. It also has the disadvantage of taking up screen space when it is open.
Another way to better view the document is to “click” on the “Up arrow” icon on the Web
Toolbar. This will minimize many of the toolbars, freeing most of the screen for viewing the
manual. “Click” the arrow again to restore the toolbars.

SECTION 1
GENERAL INFORMATION
1.1 INTRODUCTION
The purpose of this manual is to describe the proper installation and operation of the Wegener
Communications Model UNITY500 Digital Video Integrated Receiver Decoder.
1.2 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.
NOTE: Please save the packing materials and original shipping containers in case you have to
return the units for repair at some later date. Packing these units in other containers in such a
way that they are damaged will void your warranty.
1.3 PHYSICAL ENVIRONMENT
Mount the UNITY500 in a clean, dry environment, and do not place unsupported equipment on
the unit. Make sure that total rack or breaker 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 to +40oC operating temperature specification only if adequate clearance around vent-
holes is provided. In still air, this requires unblocked top vents. If several units are racked one
on top of the other, then forced rack cooling and/or ½ RU spacing is recommended for maximum
equipment lifetime.
To avoid damage to this and other equipment, or personal injury, the following items should be
strictly observed.
1.3.1 Elevated Operating Ambient
If equipment is installed in a closed or multi-unit rack assembly, the operating ambient of the
rack may be greater than the room ambient. Therefore, considerations should be given to the
TMRA, or Temperature inside the Mounting Rack, and not just inside the room.
* * * WARNING * * *
This is a Class A product. In a domestic environment this product may cause radio
interference, in which case the user may be required to take adequate measures.

Page 12 UNITY500
800001-01 Page 12 of 56
1.3.2 Reduced Air Flow
Installation of the equipment in a rack should be such that the amount of airflow required for safe
operation of the equipment is not compromised.
1.3.3 Mechanical Loading
Mounting of equipment in a rack should be such that a hazardous condition is not achieved due
to uneven loading. This unit is not very heavy, but total rack loading should be considered.
1.3.4 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.
Appropriate consideration of equipment nameplate ratings should be used when addressing this
concern.
1.3.5 Reliable Earthing
Reliable earthing of rack-mounted equipment should be maintained. Particular attention should
be given to supply connections other than direct connection to the Branch (use of power strips).
1.3.6 Desktop Installation
To set up the UNITY500 in a desktop environment, place it on a flat surface where it will not be
subject to being hit or pushed, and will not have anything spilled or dropped on it. Also, the
cables connected to the unit should be routed so they are not hit or pulled, which might cause
damage to the connectors or to the unit itself. Additionally, there should be sufficient flow of
cool air so the unit stays within its operating specifications. See Table 1(Page 13).
1.3.7 Rack Installation
When installed in an equipment rack, it is best that the UNITY500 be supported by angle
brackets or cross supports. These should be screwed or bolted securely to the equipment rack,
and be capable of supporting the unit and its connecting cables. If you have doubts as to how to
support the unit, call Wegener Communications Customer Support at the address shown in
Section 1.8 (Page 19). If you cannot do that, consult your supervisor or other authority. Do
NOT install the unit if you have doubts about the unit being safely supported.
There are also 4 holes in the front brackets, which are designed to accept screws for further
anchoring. It is also essential that these brackets be used so the unit cannot be moved forward
and fall from the rack.
It is always best to install the angle brackets or cross-members before setting the unit in place.
Then, prior to installing cables, put anchored screws or bolts-and-nuts into place on the front
brackets. Failure to do this can lead to pushing the unit out the front of the rack in later steps.

•RF Switch In (Optional Module)- Using 75-Ohm coaxial cable with a type-F connector,
connect up to four (4) RF inputs to this switch. Follow your service provider’s instructions
for proper connections. The exact antenna-to-switch connection is extremely important to
allow proper unit operation. If this module is not installed, go to “RF In” below. Ensure that
the unit’s F connector does NOT support the cable’s weight. (See Caution below.)
Note: LNB Power is DC-Blocked by the RF Switch, and is not available at any of the RF
Switch In connectors. (See RF In.)
•RF In – Using 75-Ohm coaxial cable with a type F connector, connect the output of the RF
Switch to this connector. If there is no RF Switch installed, connect the RF Input directly to
this connector. LNB power is factory set to ON. This power is available only at the RF IN
connector. (See RF Switch In.)
•Video Connections
-Composite Main: Connect the composite video output (labeled ‘Video Main’) to the
desired unit using a standard phono plug cable. The equipment it is connected to MUST
have a 75-ohm termination.
-Composite Monitor: Connect the second Composite video output (labeled ‘Video Mon’
to the desired unit using a standard phono plug cable.
* * * CAUTION * * *
When connecting cables to “F” type connectors apply a force of no
more than 12 inch/lb. (Finger tight). Avoid connecting adapters
directly to “F” type connectors. Use at minimum a 1-foot flexible
extension cable between “F” type connectors and adapters.
