Connecting The Sounder; Cable Routing Grommets - Garmin GSD 26 Installation Instructions Manual

Connecting the Sounder

When connecting the power cable, do not remove the in-line fuse holder. To prevent the possibility of injury
or product damage caused by fire or overheating, the appropriate fuse must be in place as indicated in the
product specifications. In addition, connecting the power cable without the appropriate fuse in place will void
the product warranty.
Do not force a cable into its port. Forcing the cable can damage the pins. If the cable is properly aligned, the
cable should connect easily.
Before you connect the sounder to the network, power, and the transducer, you must mount the sounder
(Mounting the Sounder, page 2).
1 Route the cables using the appropriate tie wraps, fasteners, and sealant to secure the cables along the route
and through any bulkheads or the deck.
2 Install the locking rings on the marine network and power cables
page 6).
3 Connect the bare-wire end of the power cable to a 12 Vdc power source and to ground.
4 Apply dielectric grease to the end of the power cable.
5 Align the notch on the end of the power cable with the power port on the device, and press the cable into
place.
6 Tighten the locking ring.
7 Repeat steps 4 and 5 for the network cable, and connect the device to a transducer
a Transducer or Sensor,
8 Select an option:
• If your boat is equipped with a GMS 10 network port expander, connect the network cable to an available
port on the GMS 10.
• If your boat is not equipped with a GMS 10 network port expander, connect the network cable directly to
the network port on your chartplotter.

Cable Routing Grommets

When routing cables through your boat, it may be necessary to drill holes to route the cables. Cable routing
grommets can be used to cover cable installation holes. The grommets do not create a waterproof seal. If
necessary, apply a marine sealant after installation to weatherproof around the grommet and the cable. You can
purchase grommets from your Garmin dealer or directly from Garmin at www.garmin.com.
Connecting the Device to a Transducer or Sensor
You must install cord grip plugs in any unused cord grip to make sure water cannot enter the transducer wiring
block area and damage the sounder.
The terminal blocks are not removable.
