The SC1 uses the TR1 hardware board and special firmware for statin control applications.   The station controller has many uses in the ham shack including remote power control, relay control, remotely monitor battery voltages, a simple CW memory keyer, and others.  The SC1 can be configured to run on its own or be remotely controlled through the serial port or SierraBus RS485 network interface which can support multiple devices on the same network.  The SC1 board is also a great project platform when you plan to write your own firmware.
