5.3 Serial Interfaces COM A and COM B
The CAN-CBX-COM2 module is equipped with two serial interfaces (COM A and COM B).
The base version CAN_CBX-COM2 2x RS-232 (esd-order No.: C.3055.02 ) comes with two RS-232
drivers.
The serial interface COM A is configured as RS-232 interface.
The serial interface COM B can be individually configured as RS-232, RS-422, RS-485 or
TTY-interface via Piggybacks.
In the following the wiring of the serial interfaces is shown relating to the data direction. The figures
explain the short terms of the signals used in the chapter “Connector Assignment”.
5.3.1 RS-232 Interface
In this example for the connector cable an adapter cable from the 7-pin PCB plug connector to the
DSUB9 socket is shown. This cable is designed for the direct connection of the CAN-CBX-COM2 to
a PC without a Null modem adapter.
For the individual connector assignment we recommend an adapter cable with freely configurable
DSUB connectors and sockets. Please ask for cables configured according to your specific
requirements, if required.
Attention !
Please note that the function of the control signals depends on the software drivers of the
serial interface used.
