    IR-200 MONITOR The IR-200 Monitor is normally mounted near, or on, the tank that it is tracking, usually with the Milltronics Rail Mount assembly (See drawing 0-8130004Z-DU-C). Ensure that the voltage selector switch inside is set for the power available to the unit and that liquid-tight connectors are used to seal all wires entering the enclosure.

  • Page 33: Communication Protocol

    The protocol defined in this document is used for all communications between a host computer and an InterRanger IR-200. The protocol allows the host computer to interrogate the unit to obtain information regarding the operation of the instrument. The computer may also program and control the operation of the IR-200 remotely.

    SETUP For RS-485 communication, the converter (Milltronics Part #20150158) uses 9600 BAUD as its default. Before running the program, ensure that all units are configured for 9600 BAUD rate (See BAUD RATE parameter) and that each has a unique address (See SERIAL ADDRESS parameter). A 9600 BAUD rate must be set in the IR200LOG program as well (See IR200LOG Software).
