You can use up to 32 probes on the same RS-485 line when the communication speed is 19200 bps or lower. You must configure each probe on the line to have a different Modbus address.

RS-485 termination must not be used with HMP60/HMP110 series probes.
After power-up, it may take up to 2 seconds before the probe responds to any Modbus request.
