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
