Before you begin, consider the following
installation guidelines for the belowdecks units.
• Select a mounting location in a dry, well-
ventilated area belowdecks away from any
heat sources or salt spray.
• Be sure the front panels will be easily
accessible to the user.
• Leave enough room at the rear panels to
accommodate the connecting cables.
• There are three options for mounting the
belowdecks equipment:
Option 1
- In the optional case
Option 2
- In an onboard equipment rack
Option 3
- To a horizontal surface
NOTE:
The CommBox-ACU and modem are sized to
fit a standard 19" (482.6 mm) rack, occupying 3U of
space.
• To use the supplied power/data cable, the
CommBox-ACU must be located within
100 ft (30 m) of the antenna. However, you
can order a 150 ft (45 m) cable if a longer cable
run is necessary (KVH part no. 32-1031-0150).
• Be sure the location provides adequate Wi-Fi
reception. Do not install it in an area
surrounded by metal or near any electrical
devices that emit RF noise.
