ALR-F3700 “Hydra” Series
Interconnected Reader/Antenna Combination
Three Capabilities Combined
Each Hydra reader contains a full 30dBm UHF
Passive RFID reader, an 8dBic slim-line antenna
and a network PoE switch capable of passing
through (backwards or forwards) data and
power.
Each Hydra reader has at least 2 PoE ports
allowing them to be daisy chained together into
a “string” of read points by simply connecting
the PoE cable from one Hydra reader to the PoE
port of the next reader. This enables very simple
low cost connectivity and minimal cabling costs.
In the diagram below, Hydra Readers are simply
daisy chained together with an ALR-F800-X
(with Emissary) or your existing PC/Server at
the head of the chain of Hydra’s.

Data and Power Robustness
Hydra supports more complex network
topologies for solutions where additional PoE
power is needed or where there is a desire to
build in more robustness.
Examples include where a mesh type network
is desired for data/power robustness or where
there is a need to have a long network chain
with power injected at different points down the
network to extend the chain further.
