The controller serial interface operates at 57600 baud that can be accessed using any serial TTY interface program such as PuTTY or Arduino's own Serial Monitor tool. It provides a command prompt > indicating that it is ready to receive recognized the following commands.
-
+> CAL [num] <= * Sets the clock calibration for precise timing
-> CAL <= Displays the clock calibration setting
-> DIP [val] <= * Sets the competition format, overriding the DIP switch settings
-> DIP <= Displays the competition format setting
-> FAC <= Sets saved EEPROM values to their original defaults
-> GO <= Starts operation from zero seconds, equivalent to pressing the synch button
-> ID [string] <= * Sets the callsign that gets sent
-> ID <= Displays the saved callsign setting
-> LED [on|off] <= * Turns on/off LED pin
-> LED <= Displays the LED pin setting
-> RST <= Resets the processor
-> SPD ID [num] <= * Sets the ID code speed in WPM
-> SPD <= Displays the ID code speed setting
-> STA [on|off] <= * Turns on/off the starting tones function
-> STA <= Displays the starting tones setting
-> SYN [on|off] <= * Turns on/off synchronization using sync button or "GO" command
-> SYN <= Displays the synchronization setting
-> TEM <= Displays the processor's temperature in C
-> VER <= Displays the software version number
