Power Switch
* The Ethernet RF Modem does not sup‐
port Power‐over‐Ethernet (PoE). The
device cannot be powered directly from a
PoE port on a compatible hub.
However, it may be useful to send power
on the unused wires of the CAT‐5 cable in
a situation where the radio will be
mounted in a location that optimizes radio
coverage, but may not have a power outlet
nearby. There are several third party
devices available that can inject the power
onto the cable and then remove it at the
remote side.

LEDs indicate modem activity as follows:
RSSI LEDs indicate the amount of fade margin present in an active
wireless link. Fade margin is defined as the difference between the
incoming signal strength and the modem's receiver sensitivity.
Standard Female RJ-45 connector is used to connect unshielded
twisted-pair CAT5 cabling.
7-28 VDC power connector
The antenna port is a 50Ω RF signal connector for connecting to an
external antenna. The connector type is RPSMA (Reverse Polarity
SMA) female. The connector has threads on the outside of a barrel
and a male center conductor.
The Reset Switch is used to reset (re-boot) the RF modem and force
the modem into AT Command Mode.
To reset (re-boot) the modem: Press and then immediately release
the Reset Switch.
To force the modem into AT Command Mode (at the default through-
put data rate of the modem): Press the Reset Switch and keep it
depressed for at least two seconds, then release.
