Page 10: General Information
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. -
Page 11: Security Labels
Please note the maximum per-unit power dissipation of 45 watts. SECURITY LABELS The UNITY4000 uses security labels over some of the screws. There are no user serviceable components within the unit, and tampering with the security labels or opening the units will void your warranty. -

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). -

Page 29: Operation
OPERATION 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. -

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. -

Page 35: Unit Control
Page 35 * Originally, left ÒchannelsÓ were designated Ò1Ó and right as Ò2Ó. Now ÒchannelÓ designates the selected audio program by PID. 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. -

LCD menus. 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. -

Page 40: Signal Quality Monitoring
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. -
Page 41: Display / Push Buttons
Page 41 Exceptions to the normal operation with respect to Carrier ID Tagging are: 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). -
