Please observe the following:
• The interface modules can only be exchanged in devices in flush-mounted housing. Interface modules for
devices with surface mounting housing must be retrofitted in our manufacturing centre.
• Use only interface modules that can be ordered ex-factory via the ordering code (see also Appendix, Section
A.1).
• You may have to ensure the termination of the interfaces featuring bus capability according to the margin
heading „RS485 Interface".

The ordering numbers of the exchange modules are listed in Appendix A.1.
RS232 Interface
Interface RS232 can be modified to interface RS485 and vice versa (see Figures 3-8 and 3-9).
Figure 3-7 shows the C-CPU-2 PCB with the layout of the modules.
The following figure shows the location of the jumpers of interface RS232 on the interface module.
Surface-mounted devices with fibre optics connection have their fibre optics module fitted in the console
housing on the case bottom. The fibre optics module is controlled via an RS232 interface module at the asso-
ciated CPU interface slot. For this application type the jumpers X12 and X13 on the RS232 module are plugged
in position 2-3.
Figure 3-8
Terminating resistors are not required for RS232. They are disconnected.
