3 HARDWARE INSTALLATION
WARNING! 110/220/240V mains power must NOT be connected to any input terminal
of the 505U module!
The 505U module is housed in a weatherproof enclosure with external power and input signals
connected via a weatherproof connector at the bottom of the module.
Wires of up to 0.75 sqmm may be connected by soldering to the female connector supplied with the
unit. The antenna/coaxial cable connector is a BNC at the top of the module. Care should be taken
to ensure that this connection remains weatherproof, as the ingress of water will decrease radio
performance. If necessary, wrap the connection with weatherproofing tape.
Before installing a new system, it is preferable to bench test the complete system as configuration
problems are easier to recognise when the system units are close together.
Following installation, poor communications can be caused by:
•
Incorrectly installed antennas
•
Radio interference on the same channel
•
Obstructions in the radio path
•
Radio path too long
If the radio path is a problem, higher performance antennas or a higher mounting point for the
antenna may help. Alternately, use a 105U module as a repeater.
