Industrial Bus (RS-485) wiring example
The bus leads via a 4-wire connection (two twisted pairs) from a Poseidon 1250 unit to two
daisy-chained sensors,
Temp-485 and HTemp-485 .
An S-Hub unit is daisy-chained via the RJ45 jack to the second HTemp-485 sensor using a
4-wire connection. The brown pair carries power, the blue pair is used for data.
Temp-485 and HTemp-485 sensors are connected to S-Hub connectors 1 through 3 using
6-wire connections (brown pair for power, blue pair leads the bus to the device, green pair
back from the device).
Connector 4 of the first S-Hub unit is used to connect a Spider converter with a patch cable.
The Spider unit is used to connect three Temp-1Wire 10m temperature sensors and one
door contact (the contact is connected to the blue pair of the RJ45).
Temp-485 and HTemp-485 sensors are connected to S-Hub connectors 1 through 3 using
6-wire connections (brown pair for power, blue pair leads the bus to the device, green pair
back from the device).
Connector 4 connects a Temp-485 sensor over a 4-wire connection (brown pair to power the
sensor, blue pair for the A/B signals of the bus).
The
Temp-485 sensor is configured to terminate the bus using the TERM jumper.
