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 which 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
o
C operating temperature
specification only if adequate clearance around vent-holes is provided. The units may be
