The Q71 external modem is another exciting development for DATRAN telemetry systems that can simplify future upgrades, and indeed spares holding for you.
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.
The Q71 is an RS232 device that provides the necessary DATRAN interface to conventional 1200bps radio systems. This allows you to standardise on the two serial port RTU and enjoy the flexibility to simply upgrade to high speed data radios/cellular IP etc in the future.
