RJ11 cable and either a D9 or D25 serial port connector. Before installing the V24 board it is
necessary to break out the thin plastic tongue in the moulding to allow the R J11 socket to fit in the
side of the case.
Before connecting SMDR port to the terminal device, check that the transmit (TX), receive (RX) and
ground pins of the terminal device are RS232 compatible to ensure serial data transmission
compatibility. The terminal device can be a Serial ASCII Printer or Computer.
