2.2 Transducer Cable

A 30 ft (10m) cable is supplied with the transducer. The transducer cable may be
extended up to a maximum of 60 ft (20 m) using optional extension cables.
The transducer cable connector has a nut that has been removed to aid
installation. To allow you to complete the installation without cutting the cable,
ensure that any holes you drill are large enough to accept the connector, with the
nut removed.
After the cable has been run through the holes, this nut must be attached before
the cable can be connected, as described in
CAUTION: Do Not Splice the Cable
Do not cut the transducer cable or remove the connector. Do not
try to shorten or splice the cable. If the cable is cut, it cannot be
repaired. Cutting the cable will also void the warranty.
• For a Transom mount installation – route the cable up and over the top edge
of the transom as shown in Figure 2-2 . Secure the cable using cable clamps
(available from your local marine equipment supplier).
If you do not want to expose the cable on deck, you may drill a hole 13/16"
(21 mm) through the transom for the cable (with connector attached). To
seal the opening, use a feed-thru cap where the cable passes through the
transom.
• For either type of installation – run the cable through the interior of the boat.
• If the 30 ft (10 m) cable is not long enough, extension cables are available
from your Raymarine dealer. See Table 2-1 on page 25. Total cable length from
the transducer to the DSM must not exceed 60 ft (20 m). When you attach the
extension cable, be sure that the connections are watertight. Use Dow Corn-
ing DC-4 or an equivalent sealing compound to protect the connector assem-
blies.
CAUTION:
Do not pull on the cable as this can damage the transducer wires.

Transducer Cable Connections

The transducer cable connector (and Y-connector, if supplied) has a nut that has
been removed to aid installation. To allow you to complete the installation
without cutting the cable, ensure that any holes you drill are large enough to
accept the connector, with the nut removed (approximately 13/16" or 21mm).
