Setting Port Baud Rate - Ti525 Models - Siemens SIMATIC TI525 Hardware And Installation Manual

3.3.1 Setting Port Baud Rate — TI525 Models
Figure 3-4 shows the baud rate switch assignments for the communication
ports. Switches 1 and 2 on the first switch bank (DIP 1) set the baud rate for the
RS-232-C/423 port (Port 1). Switches 3 and 4 on DIP 1 set the baud rate for the
RS-422 port (Port 2). Switch position does not matter if a device is not connected
to the port.
You need to set only switches 1 and 2 for PPX:525–1102 and PPX:505–1104
models which have only an RS-232-C/RS-423 port.

Switches 5, 6, 7, and 8 on the first bank (DIP 1) are reserved for
factory testing and should all be turned ON.
