Checking Data Connections of Interfaces
Pin Assignments
The following tables illustrate the pin assignments of the various serial device interfaces, of the time synchro-
nization interface and of the Ethernet interface. The position of the connections can be seen in the following
figure.

Operator Interface
When the recommended communication cable is used (refer to the Appendix for the ordering number),
correct connection between the SIPROTEC 4 device and the PC or laptop is automatically ensured.
Service Interface
Check the data connection if the service interface (Port C) is used to communicate with the device via fixed
wiring or a modem. If the service interface is used as input for an RTD box, verify the interconnection
according to one of the connection examples given in the Appendix
System Interface
When a serial interface of the device is connected to a control center, the data connection must be checked. A
visual check of the assignment of the transmit and receive channels is important. With RS232 and fiber optic
interfaces, each connection is dedicated to one transmission direction. For that reason the data output of one
device must be connected to the data input of the other device and vice versa.
With data cables, the connections are designated according to DIN 66020 and ISO 2110:
•
TxD = Data outputg
•
RxD = Data input
