Raymarine Echosounder Only
If you are connecting a Raymarine echosounder(s), the cable
contains a green wire. Since there is no terminal on the PC board
labelled green, you will need to use the supplies in the plastic bag
marked Raymarine to connect the green wire. If you are connect-
ing two echosounders, follow the steps below with both cables.
1. Strip an additional 10mm (3/8") of insulation from the brown wire.
2. Connect the green wire and one resistor by inserting the end of
each into separate holes in the butt connector (see Figure 5).
With the wires pushed tightly against the far inside wall of the
connector, lightly squeeze the button with pliers until it
depresses. Gently tug on the wire and the resistor to ensure
that they are securely connected.
3. Cover the resistor with a sleeve. While holding the sleeve tightly
against the butt connector, twist the free end of the resistor
together with the brown wire. Be sure the resistor is completely
covered by the sleeve to prevent a short circuit inside the
switch.
4. The twisted pair will be connected to the terminal labeled
“brown”. Follow the instructions “Connecting the Switchbox” on
page 3.

Completing the Installation
1. From outside the switchbox, carefully pull each of the cables in
turn until 100 - 150mm (4 - 6") of the cable jacket remains inside
the box (see Figure 4).
2. Use a wrench to tighten the nut on each compression fitting to
make a water-resistant seal.
3. Arrange the wires neatly inside the switchbox. Be sure that no
bare wires are touching.
4. Using the screws supplied, attach the switchbox to the selected
mounting surface at the holes previously drilled.
5. Attach the switchbox cover with the screws provided for a
water-resistant seal.
6. If they are not connected already, connect the power cable to
the power source and the echosounder(s) cable(s) to the
instrument(s).
7. Fasten all the cables in place. Coil any excess cable and
secure with cable ties to prevent damage.
Parts
Lost, broken, or worn parts should be replaced immediately.
Obtain parts from your instrument manufacturer or marine dealer.
