NOTE
The RS485 interface in devices of the SIPROTEC 4 series is a D-Sub 9 connection with a connected terminal
resistor.
If you connect devices from the SIPROTEC 5 series with devices from the SIPROTEC 4 series, then use a Y
adaptor with the order designation 7XV5103-2BA00. Complete the connection on the last device with a
terminal resistor. For the SIPROTEC 5 device, use a terminal resistor with the order designation RS485-
Terminator 7XV5103-5BA00.

Figure 4-5 Communication with a Single Master Using an RS485 Bus
The preceding figure shows the cabling using the new RJ45 sockets in a simplified format. The serial RS485
bus can be extended by simply connecting Ethernet patch cables from device to device.
