W0202 has been built to allow extension of RS485 bus using wireless technology wherever use of network cable is impossible or not cost effective. Use of two W0202 allows to build the wireless ‘bridge’ for the RS485 by building wireless remote island (one or more) for devices communicate via Modbus RTU / ASCII

Most suited for: submetering, lighting control
