REQUEST-RESPONSE PROTOCOL (RS-485)
A different data protocol is used on RS-485 interface which allows connection of multiple units on
the single RS-485 line. Before the units are connected on the single RS-485 bus, each unit must be
configured with a different device identifier. The device identifier is configured by using the PC
Configurator Utility. Refer to Chapter 5 for instructions.
The request-response protocol, unlike NMEA protocol, does not automatically report periodic flow
measurement readings. Instead, when the unit is polled form the data logger, it responds with the
current averaged flow velocity measurement.
