The Q71 is an RS232 device that provides the necessary DATRAN interface to Tait TM9315 Radio.
Until now, DATRAN RTUs have been available in two hardware variants:
● Internal 1200bps modem and one RS232 serial port
● Two RS232 ports, no internal modem (eXcel family only)
With more and more DATRAN systems converting to high speed data communications, 1200bps RTUs have become less popular.
The two RS232 port RTU variant is the cheapest RTU in the family and of course, allows you to connect both a data radio and a PLC/HMI etc.
