Station Control Subsystem
The heart of the Station Control subsystem is the Texas Instruments DM8148 Host/ DSP
processor. In general, the Station Control Module (SCM) controls the entire coordination of the
repeater functions. Specifically, the Station Control subsystem provides for the following functions:
Contains and runs the preloaded repeater software
Manages inbound and outbound RF and Audio traffic
Provides an on-board USB port for local configuring, alignment, and diagnostics through the
following applications:
- Radio Management Configuration Client (RM)
- Tuner application
- Repeater Diagnostic and Control (RDAC) software
Provides an Ethernet port for IP site connectivity and remote RDAC
Provides General Purpose Input/Output (GPIO) connectivity for third-party controller interfaces
Provides analog repeater audio connectivity
Data and Control to the Receiver subsystem through the Serial Peripheral Interface (SPI) and
Synchronous Serial Interface (SSI) respectively
Data and Control to the Exciter subsystem through the SPI and SSI respectively
Control of the Transmitter’s set power through the SPI
Configuration and fault management
Generates the internal station reference
Provides control of the front panel indicator LEDs.

Basic Repeater Level Troubleshooting – RDAC and LEDs
Diagnostic tests are available for the Transceiver of the SLR 1000 Repeater.
If a problem occurs during station operation, it is logged as an alarm that is read with the Repeater
Diagnostic and Control application (RDAC). See the following figure for the RDAC diagnostic screen.
