EB45e Quick Start Guide
Introduction
Welcome to the Quick Start Guide for the EB45e Base / Repeater
Ethernet Radio. This guide provides step-by-step instructions, with
simple explanations to get you up-and-running.
Mounting and Environmental
Considerations
The EB45e Base Station is housed in a 2RU 19” rack enclosure.
The 4 mounting holes on the front panel should be used to secure
the unit to the rack.
The radio should be mounted in a clean and dry location,
protected from water, excessive dust, corrosive fumes, extremes
of temperature and direct sunlight. Please allow sufcient passive
or active ventilation to allow the radio modem’s heatsink to operate
efciently.
All permanent connections are made at the rear of the unit. This
includes: Power, Antenna, Communications Ports, Digital I/O
and System Port. The front panel has an additional System Port
connection point for easy access.
Warning: Where an EB45e is to be operated between 50ºC and
60ºC ambient, it must be installed in a restricted access location.
Full Duplex Considerations
The EB45e is designed for continuous full duplex transmission.
An automatic thermostatically controlled fan will operate whenever
the internal temperature exceeds 40 degrees Celsius and turn off
again when the temperature goes below 35 degrees Celsius.
External Duplexer Considerations
The EB45e is normally supplied with separate Tx and Rx ports for
connection to an external duplexing system.
Depending on the frequency band of operation and the Tx/Rx
frequency split, internal band reject duplexers are available.
Power Supply and Protection
The power supply should provide a clean, ltered DC source. The
EB45e Ethernet Radio is designed and calibrated to operate from
a 13.8VDC regulated supply, but will operate from 11-16 volts
(ltered) DC.
The power supply must be able to supply sufcient current to
provide clean ltered DC under the full current conditions of the
radio modem (i.e. When transmitting full RF power). See Section L
- Specications for more details of the power supply requirements.
Caution: There is NO readily serviceable internal fuse for
an EB45e or EH45e, and therefore they both MUST be
externally fused with a fuse and fuse holder (EB45e: 5 amp fast-
blow fuse, EB45e(20W): 8 amp fast blow fuse, EH45e: 1 amp slow
blow fuse).

20W Power Amplier option
The 20W power amplier is primarily used for the purpose of
overcoming Tx combiner losses. In such cases of a 20W power
amplier being required, an Rx preamp may also be required.
Note: 20W power amplier options may not be available in all
Countries. Please contact the factory to conrm availability.
