NO ACCESS UNDER MOUNTING LOCATION
Follow these steps to deck mount the GPS receiver in a situation where you must route
the cable to the side because there is no space for a cable underneath the
mounting location.
1. Determine the best location, then test route the cable from the mounting
location to the control head.
NOTE: AS-EC10 10' extension cables are available from Humminbird® if your planned routing
exceeds 20', (6 m). Maximum cable length, including extensions, should not exceed 50' (16 m).
2. Confirm the cable length is good and route the cable from the receiver to the
control head. If holes are required to route the cable, they must be 3/4" (19 mm)
to allow for the cable connector. Secure the NMEA pigtail with electrical tape.
NOTE: Remember to caulk or seal screw holes and drilled holes as needed to protect your
boat from water damage.
3. The GPS receiver has two wire routing notches. Use the cable notch closest to
the intended cable route.
4. With the cable routed, position the GPS receiver in the planned mounting
location and mark the mounting holes with a pencil or punch.
5. Move the GPS receiver to the side and drill the two 9/64" (3.5 mm) pilot holes.
6. Align the GPS receiver's screw holes over the pilot screw holes and attach with
the #8 - 1 1/4" Phillips head screws. Hand tighten only!
FINISH ROUTING THE CABLE AND CHECK
GPS RECEIVER OPERATION
After installing a GPS receiver, you should perform the following procedure to finish
routing the GPS cable to the control head and to check to make sure that the control
head is working correctly.
1. Secure the cable along its path to the control head as needed with cable ties.
2. Plug in the GPS receiver cable into the Communications port on the control
head. See Testing the System Installation to use the System Status start-up
option and/or the GPS Diagnostic View to confirm a good installation.
