3 HARDWARE INSTALLATION
WARNING! 110/220/240V mains power must NOT be connected to any input
terminal of the 505K module!
The 505K 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 SMA female 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. Wrap both the antenna connection and input signal
connector 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.
The foldout sheet 505K Installation Guide is included with the product, with more detailed
information in the following

3.1 How to mount the
505K
The 505K module is housed in an
IP66
weatherproof aluminium
enclosure. To mount the 505K,
remove the four screws in the top
plate, and carefully remove the
cover. The two mounting holes
should now be visible.
It is important to effectively earth
the unit to help prevent radio noise
and static electricity damage. The
preferred method is to earth the
module using the mounting screws
to connect to an earthed surface.
If this is not possible, use an earth
lug in the mounting screw
connection and secure the other end of the wire to a good earth.
