These are accessed through DB-9 connectors, which plug through the rear panel into the main PWB. -
Page 24: Alarm Relay And Addressable Contact Closures
2.5.3 Alarm Relay and Addressable Contact Closures The rear panel has an alarm relay and two solid-state contact closures addressable from the COMPEL™ uplink computer. This relay’s “alarm” 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 33: Sources Of Control
SOURCES OF CONTROL The unit can be controlled via COMPEL™, terminal, modem, or Display / push buttons. Each of these methods of control is explained in the following sections, but you should see the COMPEL manual for a complete explanation of the COMPEL system. 3.6.1 Local Control Enabled/Disabled In some instances Local Control of a unit may be restricted by Network Control at the Uplink. -
Page 34: Serial Port - Command Syntax
SERIAL PORT - COMMAND SYNTAX The UNITY4422 contains two serial ports. These are labeled Serial Port 1 and Serial Port 2. Each can support a printer, a terminal, a modem, or an auxiliary data device. However, there are restrictions as to what device combinations can be used at one time. There are only 2 rules for this, and they are shown below. -

control source, the specified configuration is immediately stored for the specified device. The serial port is configured accordingly, whenever the serial_port.device is device when local panel control has been enabled by the satellite program provider. If serial_port.device is device at the time this command is issued, and the configuration differs from the current configuration, the output_buffer is cleared and the port is reconfigured. -
Page 36: Signal Quality Monitoring
The unit is acting on one of three groups of settings at any given time, each of which is described in the following table: Settings Group Temp These settings are entered via terminal commands. The unit is said to be inserting when it is configured to the temp settings. -
