Route The Cables - Humminbird ONIX8 Installation Manual

Routing the Cables
Route the Transducer Cable
The transducer cable has a low profile connector, which must be routed to the point where the
control head is mounted. There are several ways to route the transducer cable to the area
where the control head is installed. The most common procedure routes the cable through
the transom into the boat.
NOTE: Your boat may have a pre-existing wiring channel or conduit that you can use for
the transducer cable.
1. Unplug the other end of the transducer cable from the control head. Make sure that the
cable is long enough to accommodate the planned route by running the cable over the
transom.
NOTE: The transducer can pivot up to 90 degrees in the bracket. Allow enough slack in
the cable for this movement. It is best to route the cable to the side of the transducer
so the transducer will not damage the cable during movement.
2a. If you are routing the cable over the transom of the boat, secure the cable by attaching
the cable clamp to the transom, drilling 9/64" diameter holes for the #8 x 5/8" wood
screw(s), then skip directly to Connect the Transducer Cable.
2b. If you are routing the cable through a hole in the transom, drill a 1 1/8" diameter hole
above the waterline. Route the cable through this hole, then fill the hole with marine-
grade silicone sealant and proceed to the next step immediately.
3. Place the escutcheon plate over the cable hole and use it as a guide to mark the two
escutcheon plate mounting holes. Remove the plate, drill two 9/64" diameter x 5/8" deep
holes, and then fill both holes with marine-grade silicone sealant. Place
the escutcheon plate over the cable hole and attach with two #8 x 5/8" wood screws.
Hand-tighten only!
4. Route and secure the cable by attaching the cable clamp to the transom. Drill one 9/64"
diameter x 5/8" deep hole, then fill hole with marine-grade silicone sealant, then attach
the cable clamp using a #8 x 5/8" screw. Hand-tighten only!
NOTE: If there is excess cable that needs to be
gathered at one location (as shown in the
illustration), dress the cable routed from both
directions so that a single loop is left extending
from the storage location. Doubling the cable
up from this point, form the cable into a coil.
Storing excess cable using this method can
reduce electronic interference.

OUTE THE ABLES
Use the procedures in the following section to route and connect all cables to the control
head.
CAUTION! Do NOT mount the cables where the connectors could be submerged in water
or flooded. If cables are installed in a splash-prone area, it may be helpful to apply
dielectric grease to the inside of the connectors to prevent corrosion. Dielectric grease
can be purchased separately from a general hardware or automotive store.
CAUTION! Do not cut or shorten the transducer cable, and try not to damage the cable
insulation. Route the cable as far as possible from any VHF radio antenna cables or
tachometer cables to reduce the possibility of interference. If the cable is too short,
extension cables are available to extend the transducer cable up to a total of 50'. For
