Wireless serial modems allow RS232 and/or RS485 serial host devices to communicate transparently. Messages are routed between devices as broadcast or controlled mode.
The Elpro 805U-D radio modem provides RS232 or RS485 connections by radio.
It is a low cost wireless alternative for linking PLC’s, data loggers, supervisory computers and intelligent transducers.
The 805U-D has been designed to be easy to use and simple to install. It uses a low power 868MHz radio which does not require a radio licence in most European countries or South Africa.
The module is fully integrated with radio, power supply, serial ports and microprocessor controller housed in a strong industrial aluminium case.
