Humminbird 1155C - Manual (Page 25)

Access Under Mounting Location
Follow these steps to deck mount the GPS receiver when routing the cable down through the mounting
location:
1. Determine the best location, then test route the 20' (6 m) cable from the mounting location to the
control head.
NOTE: Installation details may vary with unit configuration.
2. Mark the mounting location and drill a 3/4" (19 mm) hole for the cable and cable plug. Route the
cable.
3. Cover the cable hole with the receiver. Make sure the receiver is flush on the surface and mark
the two mounting holes with a pencil or punch.
4. Move the receiver to the side and drill two pilot holes using a 9/64" (3.5 mm) bit.
NOTE: Remember to seal screw holes and drilled holes as needed with marine-grade silicone sealant to protect
your boat from water damage.
5. Align the GPS receiver screw holes over the pilot screw holes and attach with the
#8 - 1 1/4" Phillips head screws. Hand tighten only!
NOTE: If the mounting surface is thin and made of a lighter material, a backing material may be needed below
the mounting surface.
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 cable with electrical tape.
