RS 232 Communication Port

Communication serial port connections and mini- mum
connection configuration are shown in the following
figures. The communication port mating connector is
supplied with the RS 232 PCB (AMP/Cannon or
equivalent 9-pin "D" type male connector). The external
cable (not supplied) between the host computer and
the controller requires some crossed wires so that
signals are connected correctly .
For example, the Transmit data signal from controller
(pin 2) must be connected to the host computer's
Receive data line (pin 3) and vice versa. Consult the
host computer's instruction manual for its serial port
connections
