Product Description

The RS485 wireless modem is a robust, and powerful wireless transceiver with  airspeed of 16000bps for long distance and high bandwidth communication.

Operating at 470MHz and up to 1.5W, RS485 provides powerful and secure two-way wireless communication. Such as  challenging outdoor environments for typical industrial monitoring and control applications such as oil and gas wells, compressor stations, fluid storage tanks and utility meters

In order to ensure the reliability and stability of the equipment, it adopts high-performance industrial 32-bit CPU and multi-layer software control and hardware protection mechanism.
