AUXILIARY I/O BOARD
The Auxiliary I/O Board serves as the interface between a variety of aux-
iliary equipment external to the station (e.g., Trunking Controller) and the
Station Control Module (SCM). The auxiliary equipment can be Motorola
or non-Motorola equipment. If the Wild Card option is included with the
station, then some System connector inputs and outputs can be configured
through the RSS.
The Auxiliary I/O Board is installed behind the front panel, above the
Station Control Module within the option-card bracket, and is connected
to a 96-pin Euro connector (either J1 or J2) located on the backplane of the
station. The auxiliary equipment connections are routed from the System
connector (labeled J5, SYSTEM) to the Auxiliary I/O Board connector.
The Auxiliary I/O Board contains the following circuitry:
• 11 general purpose inputs (GPIs) which interface with customer
equipment.
• 11 general purpose outputs (GPOs) plus one dedicated relay driver,
which interface with customer equipment.
• Jumper fields provide routing of signals to and from the SCM.
