Please note the following:
• The interface modules can only be replaced in devices for panel flush mounting and
cubicle mounting. 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“.
Table 3-10 Exchangeable interface modules
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 3-9
and 3-10).
Figure 3-8 shows the PCB of the C-CPU-1 with the layout of the boards.
The following figure shows the location of the jumpers of interface RS232 on the inter-
face module.
Devices in surface mounting housing with fibre optics connection have their fibre
optics module housed in the console housing. The fibre optics module is controlled via
an RS232 interface module at the associated CPU interface slot. For this application
type the jumpers X12 and X13 on the RS232 module are plugged in position 2-3.

Terminating resistors are not required for RS232. They are disconnected.
