Installation Procedures

The following order of mounting the scanner and attaching the Power/Network cables may vary depending on the installation location and mount used.

Mounting the Scanner

1.When a suitable mounting location is determined, verify that the mounting hole locations are aligned fore and aft, and then drill four 9.5 mm (0.37") mounting holes referencing Figure 1 below. (This step is not necessary if you are using a pre-drilled Garmin compatible or Raymarine® mount.)

2.Align the notch and locking ring on the power cable to the power connector. Press the 2-pin power cable to the power connector and the RJ-45 marine network cable to the RJ-45 socket (Figure 2). Turn the power cable locking ring clockwise until it stops. Tighten the RJ-45 locking ring clockwise until it is firmly sealed.

3.The power/network cable may be pressed into one of the five guide grooves molded into the bottom of the scanner case and secured under the cable hold-down plate (Figure 2). Avoid excessive bending or twisting of the cable. See the following “Cable Runs” section for more information.

4.Position the scanner on the mounting surface with the triangular mark on the case aligned to the front of the vessel. Apply a bead of marine sealant around each of the mounting holes on the mounting surface.

5.Install the four (4) M8 x 1.25 x 60 threaded rods into the Mounting Holes on the bottom of the scanner. There should be no more than 50 mm (2") extruding from the scanner when they are installed properly.

6.Fasten the scanner to the mounting surface using the M8 x 1.25 x 60 threaded rods (installed in the previous step), spring washers, flat washers, and M8 Hex nuts as shown in Figure 3. The nuts should be torqued to between 13.7-18.6 Nm (10-14 lb ft).

Note: The supplied M8 x 1.25 x 60 threaded rods can be used on mounting thicknesses of 5-30 mm (1 1/8") (recommended). For surfaces over 30 mm (1 1/8"), locally supplied longer threaded rods are needed.
