POWER SUPPLIES:
The E306 models require a 5VDC
source which can be provided from the universal 100-260V AC power supply containing plug types for
most regions which is included with the E306 device and is an option on the E312 models. A 5 VDC
Power over Ethernet (PoE) source can also be used.
The E312 models can run off of battery power or use the same (optional) AC power supply as the E306.
Using battery power requires 2 x AA alkaline batteries which will provide two years of battery life under
typical usage. Note that the AA batteries are not a backup to the external power supply; if the external
power supply is plugged into the E312, battery power is deactivated. Batteries should not be left in a
unit that is powered by the external power supply.
See below for information on how the unit’s
behavior changes when operating under battery power.
USING A POE (POWER OVER ETHERNET) SOURCE : The E306 and E312 and the
Gateway units are not native PoE devices but can be powered by a PoE source
using a standard PoE splitter. The PoE source should have a 5VDC output (not
12 VDC). The monitor and Gateway consume 0.5W and 0.7W respectively.
DEVICE PLACEMENT
DEVICE PLACEMENT

Do not locate the monitoring node inside of a fully
enclosed metal structure

Some separation from metallic surfaces improves radio
performance.

Mounting brackets provide some separation between the
monitoring unit and metal surfaces such as cabinets and
can at times improve radio performance meaningfully.
o
The optional mounting bracket (PN: MOUNT-
EGEM) is used with the E306. It comes with an adhesive pad and can also be fastened
using screws or cable ties. This same bracket can be used with the Ethernet Gateway.
