RS485 and RS232 Interfaces
5.2.2 Pin Assignment
5.2.2.1 RS232 Communication Module CM-232 DB9
X310
The RS232-Interface is connected to a PC or a controller via
the 9-pin D-Sub socket X310.
The assignment complies with the standard, so that only an
RS232 connection cable (1:1) is required.

5.2.3 RS485 Bus Termination
Attention!
The passive bus termination (connection of a termination resistor), is required at the physically first
and last client. It can be activated by the CM-485 and CM-485T DIP Switch S1.
By default, the bus termination is set to OFF.
It is important to implement a correct termination. Otherwise, no communication is possible via the
RS485-Interface.
As an alternative, the active bus termination is possible via a corresponding circuit:
The active termination is only allowed once on each branch. The bus termination via an external cir-
cuit and via DIP switch at the same time is not allowed.
Pay attention to the ground wiring. This will protect the communication bus against high noise level.
For easy wiring the signal terminals A and B have parallel contacts.
