5.2 Optional JCU mounting
Location requirements
When planning the installation location, consider the following
points:
• Select a position on your vessel that is close to the monitor
that displays the T-Series camera video output.
• Ensure the JCU is mounted at least 55 cm (21.7") away from
any equipment fitted with a magnetic compass.
• The JCU can be mounted to a dash or other surface in any
orientation.
• Consider cable lengths and cable routing.
Flush mounting
The standard method for mounting the JCU is a flush or panel
mounting arrangement.
Before mounting the unit, ensure that you have:
• Selected a suitable location. A clear, flat area with suitable
clearance behind the panel is required.
• Identified the cable connection required and the route that
the cable will take.
• Detached the front bezel to reveal the mounting screws.
Mounting the JCU
1. Cut the mounting hole according to the dimensions specified
in the mounting template included in this document.
2. Ensure that the unit fits into the removed area and then file
around the cut edge until smooth.
3. Drill four 6.4 mm (0.25 in) holes as indicated on the template
to accept the mounting screws.
4. Before mounting the JCU, insert the supplied ethernet cable
through the mounting hole and into the JCU ethernet port.
Ensure the cable gland sealing nut is tightened correctly.
5. Remove the 4 panel mounting clamps and insert the JCU in
place. Affix the mounting clamps to the screws on the other
side of the mounting surface, ensuring that the mounting
clamps are rotated outward from the JCU housing. Tighten
the screws to draw the mounting clamps up against the
mounting surface and then tighten another 1/4 to 1/2 turn. Do
not overtighten the screws.
i.
As shipped from the factory, the JCU can be mounted
to a panel thickness ranging from 0.79 to 4.45 cm (0.31
to 1.750 in). The clamps are set with the small “foot” on
the clamp facing towards the mounting surface, away
from the front of the JCU, as shown in the "Thick panel
mounting" diagram in this document.
ii. To mount the JCU to a panel thickness of 0.79 cm (0.31
in) or less, remove the clamps from the mounting screws,
turn them around and thread them back onto each of the
four screws. In this configuration, the clamp “foot” faces
away from the mounting surface and allows the clamp
to contact thinner panel surfaces while still allowing for
proper compression of the JCU mounting gasket to form
a watertight seal. This mounting configuration is shown in
the "Thin panel mounting" diagram in this document.
6. Once you have secured the JCU in place, replace the bezel.
