Connection example via RS-485

The bus leads via a 4-wire connection from a Poseidon 1250 unit to two daisy-chained sensors,
Temp-485 and HTemp-485 . Two twisted pairs are used for the connection.

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 is used to connect three Temp-1Wire 10m sensors and one contact (door contact connects to
the blue RJ45 pair).

The second S-Hub unit is connected with a patch cable to the Spider output.

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).
Termination is enabled at the Temp-485 sensor using the "TERM" jumper.
