Plug the RS485 (and sensor) cable connector into the gauge.
Sensor cable
RS485 cable
Lock the RS485 (and sensor) cable connector.
The gauge can now be operated via RS485 interface ( → 37).
The optional 24 V power supply ( → 52) allows RS232C operation of the BPG400
gauge with any suitable instrument or control device (e.g. PC).
The instrument or control device needs to be equipped with a software that sup-
ports the RS232C protocol of the gauge (
→ 31).
