User manual GARMIN GSD 21 INSTALLATION INSTRUCTION

[. . . ] Within this period, Garmin will at its sole option repair or replace any components that fail in normal use. Such repairs or replacement will be made at no charge to the customer for parts or labor, provided that the customer shall be responsible for any transportation cost. This warranty does not cover failures due to installation errors, abuse, misuse, accident, or unauthorized alteration or repairs. THE WARRANTIES AND REMEDIES CONTAINED HEREIN ARE EXCLUSIVE AND IN LIEU OF ALL OTHER WARRANTIES EXPRESS OR IMPLIED OR STATUTORY, INCLUDING ANY LIABILITY ARISING UNDER ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE, STATUTORY OR OTHERWISE. [. . . ] If you experience difficulty with the installation, contact Garmin Product Support. If you are connecting a CANet compatible unit, follow the CANet installation instructions. Using the CANet installation optimizes the performance of the CANet-compatible units. CANet compatible unit devices features, such as UltrascrollTM, are affected if a serial installation is used. 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. NOTE: When using the chartplotter and GSD 21 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 21 to shut off. Using the module as a template, mark the location of the four mounting holes. If needed, additional mounting holes can be drilled in the side mounting flanges of the module. Attach the GSD 21 to the mounting location using appropriate fasteners. Mount the transducer according to the instructions provided with the transducer. Route the cables according to the CANet or Serial instructions to the mounting locations of the display unit. Use the appropriate tie-wraps, fasteners, and sealant to secure the cable along the route and through any bulkhead or deck. After installing the GSD 21 module, connect the power/data and transducer cables to the appropriate receptacle. Refer to the following CANet and serial wiring diagrams for connecting the GSD 21 to compatible Garmin units. NOTE: You can extend the CANet wiring of the GSD 21 power/data cable up to 80 ft (24. 38 m) total length using the CANet Connections Kit. NOTE: You can extend the serial/power wiring of the GSD 21 power/data cable up to 100 ft (30 m) total length. Use the CANet Extension Cable or 22 AWG, 4-conductor shielded cable for data connections and 18 AWG for power. WARNING: Do not connect or disconnect the transducer while the MFD and GSD 21 are connected and turned on . [. . . ] Codes are: Code Green blinking, on for 1 second, off for 1/2 second (slow blink) Status GSD 21 is servicing one directly wired connection and the display device is operating properly. In this state, the GSD 21 does not transmit any sonar signals and is not sending out any sonar information to display units. If a display unit is connected and this code persists, check the wiring. If the cause is a software error, the display unit can show the error. [. . . ]
