AirGate Modbus (Gateway RS-485/Wireless)

AirGate-Modbus is a wireless multifunctional gateway that allows the transparent and easy insertion of wireless branches into existing wired RS-485 networks. The AirGate-Modbus has four operation modes, Modbus Master, multiplexer, USB-RS-485 converter and simple wireless RS-485 extension. A proprietary protocol based on IEEE 802.15.4 facilitates operation in Star mode, allowing the connection of several wireless segments to an existing Modbus RS-485 network.
