Control Overview
The heart of the Station Control Module (SCM) is the two Texas Instruments OMAP1710 processors. Each OMAP
processor contains an ARM Host and a C55 DSP processor. One of these OMAP processor is dedicated to
Receiver DSP operations, while the other OMAP provides for all other operations, including the transmitter
functions.
The SCM controls the entire coordination of the base station/repeater functions. Specifically, the SCM provides for
the following functionalities:
Contains and runs the preloaded base station/repeater software
Manages inbound and outbound RF and Audio traffic
Provides external speaker and microphone ports
Provides an on-board USB port for local configuring, alignment and diagnostics via the following
applications:
- Customer Programming Software (CPS)
- Tuner application
- Repeater Diagnostic and Control (RDAC) software
- Online Help
Provides an Ethernet port for IP site connectivity and remote RDAC
Provides GPIO connectivity for third party controller interfaces
Provides for analog base station/repeater audio connectivity
Data and Control to the Receiver via the SPI and SSI respectively
Data and Control to the Exciter via the SPI and SSI respectively
Control of the PA’s set power via the SPI
Generates the internal station reference
Provides control of the front panel status indicators
