MT166 Card Dispenser Serial Interface
The serial interface to the MT166-RF card dispenser uses 9600 baud, 8 data bits, even parity, 1 stop bit, and no parity.
Below are oscilloscope traces of the communications lines going into the card dispenser during communications. First is a trace of communications between the FasCard Touch Kiosk and the card dispenser:
Channel 1 (yellow): card dispenser serial port pin #2, touch kiosk transmitting to card dispenser
Channel 2 (magenta): card dispenser serial port pin #3, card dispenser responding to touch kiosk
The touch kiosk uses a 'proper' RS-232 driver, so when idle (logical 1) the touch kiosk's transmit line is roughly -8V and when signalling (logical 0) it is roughly +10V.
Second is a trace of communications between the FasCard Add-Value Kiosk and the card dispenser:
Channel 1 (yellow): card dispenser serial port pin #2, add-value kiosk transmitting to card dispenser
Channel 2 (magenta): card dispenser serial port pin #3, card dispenser responding to add-value kiosk
The add-value kiosk can only supply 0-5V to its serial lines, so when idle (logical 1) the touch kiosk's transmit line is close to 0V and when signaling (logical 0) it is +5V.
