Contact pin of the connector Instruction
1 - Unused
2 - Unused
3 B-Line Positive data(twisted pair cables 1)
4 RTS Sending requirement
5 GND_BUS Isolation ground
6 +5V BUS Isolated 5V DC power supply
7 - Unused
8 A-Line Negative data(twisted pair cables 2)
9 - Unused
Housing SHLD PROFIBUS shielded cable
+5V and GND_BUS are used in the fieldbus terminals. Some devices, such as light
transceiver (RS485) may get external power supply form these pins.
RTS is used in some devices to determine the sending direction. Only A-Line wires, B-Line
wires and shield are used in the normal application.
It is recommended to apply the standard DB9 connector of SIEMENS. If the communication
baud rate is above 187.5kbps, please follow the connection rules of SIEMENS seriously.
