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 and network cables may be pressed into any 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 cables. 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 N-m (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 (3/16" - 1 3/16") (recommended). For surfaces over 30 mm (1 3/16"), locally supplied longer threaded rods are needed. 2 mm Distance Gauge 2 meters (6 1/2 ft) 16 AWG 4 meters (13 ft) 14 AWG 6 meters (19 ft) 12 AWG Wire Gauge Table Figure 1 Plate Scanner Power Mounting connector holes Mounting bracket Flat washer Spring washer M8 x 60 Network threaded connector rod Cable routing M8 nut options Figure 2 Figure 3 GMR 18/24 Marine Radar Installation Instructions GMR 18/24 Marine Radar Installation Instructions Cable Runs Route the cables as needed, depending on the type of mount you are using. It may be necessary to drill 31.7 mm (1.25") holes for routing the power or network cable. Garmin provides a rubber cable grommet which may be used to cover a cable installation hole. The grommet does NOT provide a waterproof seal. To waterproof the grommet, apply a marine sealant. Additional cable grommets can be purchased through Garmin or a Garmin dealer. When installing the power and network cables, observe the following: It is not recommended to cut the RJ-45 marine network cable, but the GMR 18/24 package includes a field install kit if it is necessary to do so. Make sure you save the end you cut. It is important that the wires are connected to the new RJ-45 connector the same way. To ensure safety, use the appropriate tie-wraps, fasteners, and sealant to secure the cable along a route and through any bulkhead or deck. Avoid running the cables near moving objects, high-heat sources, or through doorways and bilges. Avoid installing the cables next to or parallel to other cables, such as radio antenna lines or power cables. This is essential to avoid interference to or from other equipment. If this is not possible, shield the cables with metal conduit or a form of EMI shielding. Install the power cable as close to the battery source as possible. A minimum of 10.5 VDC is required during radar turn-on and operation. Reference the wire gauge table on the previous page when using extended runs of wire between the power cable and the battery. Final Wiring Connections Making the final wiring connections 1. Connect the Black ground (-) wire to the vessel’s negative power terminal. 2. Connect the Red power (+) wire (with fuse holder) to the vessel’s positive power terminal. Warning: Do not cut the fuse holder from the red wire. The fuse holder must remain in place for the GMR 18/24 to function correctly. Removing the inline fuse holder may damage your boat's circuitry. 3. For a stand-alone network (chartplotter and radar only), attach the RJ-45 marine network cable to the RJ-45 socket on the back of the chartplotter. For an expanded network (chartplotter, radar, GMS 10, etc.), attach the RJ-45 marine network cable to an open RJ-45 socket on the GMS 10 network port expander. Tighten the RJ-45 locking ring clockwise until it is firmly sealed. Note: If you are using a Garmin GPSMAP 4000 or 5000 series chartplotter, you may not need a GMS 10 network port expander. The GPSMAP 4000 and 5000 series chartplotters have multiple RJ-45 sockets. Stand-alone Network GMR 18/24 marine radar GPS 17 Garmin Chartplotter NOTE: When using the GMR 18/24 with a stand-alone network, the chartplotter and GPS antenna (GPS 17) must be installed according to their installation instructions. This diagram only shows how a GMR 18/24 radar communicates with a stand-alone network and does not illustrate the full wiring needs of the chartplotter or GPS 17. Note: Both the GMR 18/24 and Garmin chartplotter must be connected to a power source according to their installation instructions. This diagram only illustrates the network data connections. • • • • GMR 18/24 Marine Radar Installation Instructions Expanded Network Garmin GMS 10 marine network port expander Garmin GDL 30/30A marine weather/aud...
