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.
