Wireless serial links... RS232 or RS485
The ELPRO 405U radio modem module provides RS232 or RS485 connections by radio. It can be used instead of serial cable to link PLC’s, dataloggers, supervisory computers and intelligent transducers.
The 405U has been designed to be easy to use and simple to install. It uses a low power UHF radio which does not require a radio licence*. The module is fully integrated with radio, power supply, serial ports and microprocessor controller housed in a strong industrial aluminium case.
The 405U includes a radio transceiver, allowing communications in both directions, so the modules can check and control the transfer of information.
