NOTE

For a direct connection to DIGSI with interface RS232 jumper X111 must be plugged in position 2-3.

If there are no external terminating resistors in the system, the last devices on a RS485 bus must be config-
ured via jumpers X103 and X104.

Note: Both jumpers must always be plugged in the same way!
When the device is delivered from the factory, the terminating resistors are disconnected (jumper setting 1-2).
The terminating resistors can also be connected externally (e.g. to the connection module as illustrated in
Figure

). In that case the terminating resistors provided on the C-CPU- 2 processor board must be

switched off.
Jumper X90 has no function. The factory setting is 1-2.
