RS232 Interface
The RS232 interface can be transformed into a RS485 interface and vice versa, according to Figure 3-17.
Figure 3-15 shows the PCB C-CPU-2 with the layout of the boards.
Figure 3-16 shows how jumpers of interface RS232 are located on the interface module.

Figure 3-16 Location of the jumpers for configuration of RS232
Terminating resistors are not required. They are disconnected.
Please observe that in surface-mounted devices with fibre optics connection the CPU module is equipped with
an RS232 interface module. In this application, the jumpers X12 and X13 on the RS232 module are set to posi-
tion 2-3, unlike the arrangement shown in Figure 3-16.
Jumper X11 is used to activate the flow control which is important for the modem communication.
