2 GSD 22 Sonar Module
INSTALLATION INSTRUCTIONS
INSTALLATION INSTRUCTIONS
The GSD 22 must be properly installed according to the following CANet or Marine Network installation instructions to get the best possible
performance. Refer to your chartplotter to determine the correct installation method. To complete the installation, you need appropriate
fasteners. If you experience difficulty with the installation, contact Garmin Product Support.
The module should be mounted in an out-of-the-way location that is dry and well ventilated. Avoid mounting the module where it can be
submerged in liquids or exposed to extreme temperatures. Be sure to mount the module so that the LED is visible.
To install the GSD 22 sounder module:
1. After the location is chosen, place the unit. Be sure to allow enough clearance for attaching the cables. Using the module 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 according to the CANet or Marine Network instructions on the next 3 pages. Use appropriate tie-wraps, fasteners, and
sealant to secure the cable along the route and through any bulkhead or deck.
5. After installing the GSD 22 module, connect the power/data and transducer cables to the appropriate receptacle.
6. Refer to the following CANet or Marine Network wiring diagrams for connecting the GSD 22 to compatible Garmin units.
NOTE: You can extend the CANet wiring of the GSD 22 power/data cable up to 80 ft (24.38 m) total length using the CANet Connections Kit.
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 port on the unit.
4. If networking the MFD with the Garmin Marine Network, insert the RJ-45 connector into the NETWORK port on the back of the unit and
screw the locking ring in clockwise until it is firmly seated. The CANet installation does not require the NETWORK port.
With power applied to the circuit, test the installation by pressing the POWER key on the front of the MFD. The GSD 22 turns on
automatically when the MFD is turned on.
WARNING: During peak transmit conditions, the heat sink might become hot.
WARNING: Do not connect or disconnect the transducer while the MFD and GSD 22 are connected and turned on . Doing so might damage the
GSD 22.
NOTE: 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 units 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/installer if problems persist.
