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. |
