Installation Instructions; Selecting A Mounting Location - Garmin GSD 22 Installation Instructions Manual

The GSD 22 must be properly installed according to the following Marine Network installation instructions to get the best possible
performance. If you experience difficulty with the installation, seek the assistance of a professional installer, or contact Garmin Product
Support.

Selecting a Mounting Location

• Mount the GSD 22 in an out-of-the-way location that is dry and well ventilated.
• Avoid mounting the device where it can be submerged in liquids or exposed to extreme temperatures.
• Mount the GSD 22 so that the LED is visible.
• Allow enough clearance for attaching the cables.
Installing the GSD 22
1. Place the GSD 22 in the selected location. Using the GSD 22 as a template, mark the location of the four mounting holes.
2. Attach the GSD 22 to the mounting location using appropriate fasteners.
3. Mount the transducer according to the instructions provided with the transducer.
4. Route the cables using appropriate tie-wraps, fasteners, and sealant to secure the cable along the route and through any bulkhead or deck.
Refer to the following sections: GSD 22 Wiring Connection, and Marine Network Wiring and Cables.
5. Connect the power/data and transducer cables to the connectors on the back of the GSD 22.
6. Refer to the Marine Network wiring diagrams on
Note: You can extend the power wiring of the GSD 22 power/data cable up to 100 ft (30 m) total length using 18 AWG wire. Transducer cable
extensions are available through your Garmin dealer.
GSD 22 Wiring Connection
To install the power, transducer, and network cables:
1. Align the notch and locking ring tab on the black Power cable with the POWER port on the front of the GSD 22. Carefully press the cable in
until it is firmly seated. Do not force the cable, as this may damage the pins!
2. After the cable is seated, turn the locking ring clockwise until it stops.
3. Repeat steps 1 and 2, attaching the transducer cable to the TRANSDUCER connector on the GSD 22.
4. To connect the GSD 22 to your Garmin Marine Network, insert the RJ-45 connector into the NETWORK port on the back of the GSD 22 and
turn the locking ring clockwise until it stops.
With power applied to the circuit, test the installation by pressing the POWER key on the front of the chartplotter. The GSD 22 turns on
automatically when the chartplotter is turned on.
When using the chartplotter and GSD 22 on battery power only (engines off) for extended periods of time, be sure there is enough available
amperage to run the devices for the time period. Running other onboard devices at the same time can lower the available amperage, causing the
chartplotter and/or GSD 22 to shut off. Check with your local marine dealer or installer if problems persist.
CAUTION: During peak transmit conditions, the heat sink might become hot.
NOTICE: Do not connect or disconnect the transducer while the chartplotter and GSD 22 are connected and turned on. Doing so might damage the
GSD 22.
