Front panel

The inside of the front panel showing the 2 toggle switches wired to a connector to plug into the logic board.

 

These switches control the transmitter enable and line relay signals. Each switch has 3 positions. 'Down', the signal is permanently on. 'Middle', it's permanently of. And 'Up', it's controlled by an RS232 input (RTS for transmitter enable, DTR for the line relay).

 

Also here are 2 more tapped spacers to mount the LED board.
