2.0 Mounting and Environmental
Considerations
The EB450 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
sufficient passive or active ventilation to allow the radio
modem’s heatsink to operate efficiently.
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.
(see Fig 1 for details)
2.1 Typical Radio Setup
2.1 Full Duplex Considerations
The EB450 is designed for continuous full duplex
transmission. An automatic thermostatically controlled fan
will operate whenever the internal temperature exceeds
50 degrees Celsius.
2.2 External Duplexer Considerations
The EB450 is normally supplied with seperate 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.

3.0 Connecting Antennas and RF
Feeders
The RF antenna system should be installed in
accordance with the manufacturers notes.
The RF connectors used on the EB450 radio are N Type
female connectors. Always use good quality low loss
feeder cable, selected according to the length of the
cable run. Ensure all external connections are
waterproofed using amalgamating tape.
Preset directional antennas in the required direction using
a compass, GPS, or visual alignment and ensure correct
polarisation (vertical or horizontal).
System Port pinout assignments:
Pin 1 System port data out (RS232)
Pin 2 System port data in (RS232)
Pin 3 Not used
Pin 4 Shutdown
Pin 5 Not used
Pin 6 Not used
Pin 7 Ground
Pin 8 External PTT
Special user pinouts:
• Shutdown (Pin 4) - Active low for power save function
• External PTT (Pin 8) - Provides a manual PTT override
facility for enabling the transmitter. For testing this can
be activated by connecting PTT (Pin 8 ) to Gnd (Pin 7).

4.0 Communications Ports
4.1 System Port - RJ45
The System Port (available at the front and rear of the
unit) is a multi-function interface used for:
• Programming / Configuration of the radio
• Remote Diagnostics connections
To access these functions use the standard E Series
System Cable assembly (RJ45 Cable and RJ45 to DB9
Adaptor).
