RS-232 communication
MPC-684 has two RS-232 communication ports for interfacing to external devices.
You can control the ports by using commands.
One of the ports supports interfacing with the GP touch-panel (Digital corporation).
You can add more communication ports by using the MRS-402 board (max 4ch.)
