DSUB–socket
A 9-pole DSUB–socket (PC–Interface, RS232) is used for the communication between PC
and a remote protection device via CC–2M. The connection cable between the PC and
CC–2M is the standard DIGSI–communication cable 7XV5100–4. It is a non–isolated
interface and therefore it is not designed for the transmission of time–critical data.
Figure 18 DSUB–socket at the CC–2M
The following figure shows a connection plan. A gender changer is required for the opposite
side.

Optical Fibres
The fibre–optic links (Figure 20) are provided with cover caps to prevent the ingress of dirt.
They can be removed by turning them 90° counter clockwise. When the interfaces are not
used, the cover caps shall not be removed.
