Cable requirements
You must consider the following points before installing the system cables:
• You need to connect the scanner to the multi-function display unit and
power (and, if appropriate, via a SeaTalk
hs
switch).
• All cables should be adequately clamped and protected from physical
damage and exposure to heat - avoid running cables through bilges or
doorways, or close to moving or hot objects.
• Acute bends must be avoided. The digital cable for connecting the
Digital Radome scanner to a multi-function display and power source
has a minimum bend radius of 45mm (or diameter of 90mm).
• Where a cable passes through an exposed bulkhead or deckhead, a
watertight gland or swan neck tube should be used.
• Avoid cutting and rejoining cables.
Scanner cables
Running the cable to the scanner
DO NOT pull the cable through bulkheads using a cord
attached to the connector. This could damage connections.
The cable connector is at the rear of the scanner unit. If the unit is mounted
on a hollow mast, the cable may be run inside the mast and connected to
the unit. Make sure that the cable does not chafe where it enters and exits
the mast. To minimize electrical interference try to avoid running radar
cables near other onboard electrical equipment. It is also good practice to
avoid running radar cables in parallel with other antenna or power cables.
Digital cable
A digital cable, illustrated below, is required. This provides both power and
SeaTalk
hs
signals to the Digital Radome scanner. It is fitted with a
SeaTalk
hs
plug, and power cores for connecting to the scanner.
Digital cables are available in the following lengths:
• Part No. A55076 - 5 m cable.
• Part No. A55077 - 10 m cable.
• Part No. A55078 - 15 m cable.
• Part No. A55079 - 25 m cable.
The following extension cables are also available:
• Part No. A92141 - 2.5 m extension cable.
• Part No. A55080 - 5 m extension cable.
• Part No. A55081 - 10 m extension cable.
For boats with 12 V DC power systems, the maximum cable length is 25 m
(including any extension). If you need to run a longer cable length with a
12v supply, please contact Raymarine technical support for further advice.
Note: Do not make your own cables for use with the Digital Radome
scanner. Only use official Raymarine cables.
