Introduction

RFR400 433MHz Router is an efficient and powerful data repeater suit for different applications. It supports both star and mesh topology that can significantly extend the coverage range. Besides, RFR400 have two mode of operation, one is auto-organized mode and the other self-assigned mode.

RFR400 is suitable for non-network environment to repeat the signal back to reader. It can be plug and play by setting auto-organized mode.

There are failover and load balance functions to avoid failure or overload of single node.

Implementation Notice







Keep away from potential RF radiators such as electronic / radio equipments for minimizing interference, i.e. engine, monitor etc, utilize the channel clear detection feature to pre-scan the interference and then choose the best place to setup the reader. And readers should be mounted at reasonable height for better performance.

RFR400 supports wide range of antennas for different coverage areas, high quality SMA coaxial cable may be use to separate the antennas from Reader.

RFR400 is typical indoor used, for outdoor environment the Reader can be protected in a NEMA enclosure. The operation performance will be reduced the negatively impacted by nature weather conditions such as moisture, excessive temperature.
