RS232/485 interface
Options for using the serial interface include transparent data transfer, control of
connected devices or operation of the unit with a terminal program. Depending
on the setting, the interface works with the RS232 or RS422/485 protocol. The
protocol used depends on the current configuration (see page 56).
The pin assignments depend on the protocol used.
Note
For RS422/RS485 pin assignment is also possible for 2-wire connection.
– Connect the TxD+ with the RxD+. TxD+ then is equivalent to DATA+.
– Connect the TxD- with the RxD-. TxD- then is equivalent to DATA-.
