8.5 Cable Runs

Consider the following before installing the system cables:
• You need to attach the power cable and the scanner cable. Additional
cables will be required if you are installing an integrated system.
• All cables should be adequately secured, protected from physical damage
and protected from exposure to heat. Avoid running cables through bilges
or doorways, or close to moving or hot objects.
• Acute bends must be avoided
• Where a cable passes through an exposed bulkhead or deckhead, a water-
tight feed-through gland or swan neck tube should be used.
• Secure cables in place using tie-wraps or lacing twine. Coil any extra cable
and tie it out of the way.
• Avoid cutting and re-joining cables (if necessary, refer to the notes below).
You need to run the following cables:
• Power/NMEA Input cable, supplied with the display unit. This has a con-
nector plug at one end for connecting the display unit, and 7 wires at the
other end for connecting the power supply and optional NMEA inputs (see
Section 8.11, Integrated Systems).
CAUTION:
Do not pull the cable through bulkheads using a cord attached to the
connector. This could damage the connections.
• Inter-unit cable, supplied with the scanner unit. This is Vinyl-covered and
shielded, with a connector plug at one end for connecting to the display unit
or extension cable; the other end of the radome scanner cable is fitted with
an 8-way plug and power cores (covered by a clear protective sleeve) for
connecting to the scanner.
• SeaTalk/NMEA Output cable, optional, with SeaTalk connector(s) at
one or both ends.
Rejoining Cables
You should avoid cutting and re-joining cables. If this is necessary you must:
• Fit a ferrite on each side of the join. The specific ferrite to use depends on
the cable type - contact Raymarine for details.
• Take care not to damage any of the wires. Make sure that all the wires and,
in particular, the screen are reconnected correctly.
If you are mounting the scanner on the mast of a sailboat, and will need to
unstep the mast, you should install a suitable junction box inside the boat.
