WMO-400S Series High Performance Modem

Quick Overview

The WMO-400S Series Radio modems are a range of high performance modems. The modems have the ability to transfer data at 19.2kb/s over distances up to 100Km using a frequency range between 430 - 490MHz bands which are licenced and licence-free radio channels. The unit features two RS232 and one RS485 connection, (two data ports and one configuration port).

Details

The WMO-400S radio modem provides RS232 or RS485 connections by radio. It provides are wireless connection between a PLC and remote dataloggers, sensors and supervisory computers.

The WMO-400S has been designed to be easy to use and simple to install. It operates in the frequency range of 430-490MHz, with low and high transmitter power and a maximum achieveable range of up to 60 miles (100Km). Each modem can operate as a repeater and to a serial device, allowing the units to optimise the network and an increased range.
