Garmin GPS 19x NMEA 2000 Installation Instructions - Page 2

1 Use a pencil to mark the three screw locations and to trace the cable-hole in the center of the bracket. 2 Set the surface-mount bracket aside. Do not drill through the surface-mount bracket. 3 Drill the three 1/8 in. (3.2 mm) pilot holes. Note: If you are mounting the GPS 19x on fiberglass, it is recommended to use a countersink bit to drill a clearance counterbore through the top gelcoat layer (but no deeper). This will help to avoid cracking in the gelcoat layer when the screws are tightened. 4 Use a 1 in. (25 mm) hole saw to cut the cable hole in the center. 5 Place the seal pad ➋ on the bottom of the surface-mount bracket, aligning the screw holes. 6 Use the included M4 screws to attach the surface-mount bracket to the mounting surface. 7 Route the cable ➌ through the 1 in. (25 mm) hole and connect it to the antenna. 8 Verify that the large gasket ➍ is in place on the bottom of the antenna, place the antenna on the surface-mount bracket, and twist it clockwise to lock it in place. 9 Secure the antenna to the mounting bracket with the included M3 set screw ➎. 10 Route the cable away from sources of electronic interference, and connect it to your NMEA 2000 network (page 3). 8 Route the cable away from sources of electronic interference, and connect it to your NMEA 2000 network (page 3). Mounting the Antenna with the Cable Routed Through the Pole 1 Position a standard 1 in. OD, 14 threads per in., pipe-threaded pole (not included) in the selected location, and mark the approximate center of the pole. 2 Drill a hole using a 3/4 in. (19 mm) drill bit for the cable to pass through. 3 Fasten the pole to the boat. 4 Thread the pole-mount adapter onto the pole. Do not overtighten the adapter. 5 Route the cable through the pole and connect it to the antenna. 6 Place the antenna on the pole-mount adapter and twist it clockwise to lock it in place. 7 Secure the antenna to the adapter with the included M3 set screw ➊. ➊ Mounting the Antenna on a Pole With the included pole-mount adapter attached to the antenna, you can install it on a standard 1 in. OD, 14 threads per inch, pipe-threaded pole (not included). You can route the cable outside of the pole or through the pole. Before you permanently mount the antenna, test the mounting location for correct operation (page 1). Mounting the Antenna with the Cable Routed Outside of the Pole 1 Route the cable through the pole-mount adapter ➊, and place the cable in the vertical slot ➋ along the base of the pole-mount adapter. ➌ ➊ ➋ 2 Screw the pole-mount adapter onto a standard 1 in. OD, 14 threads per in., pipe-threaded pole (not included). Do not overtighten the adapter on the pole. 3 Connect the cable to the antenna. 4 Place the antenna on the pole-mount adapter and twist it clockwise to lock it in place. 5 Secure the antenna to the adapter with the included M3 set screw ➌. 6 With the antenna installed on the pole mount, fill the remaining gap in the vertical cable slot with a marine sealant (optional). 7 Attach the pole to the boat if it is not already attached. ➋ 8 With the antenna installed on the pole mount, fill the vertical cable slot ➋ with a marine sealant (optional). 9 Route the cable away from sources of electronic interference, and connect it to your NMEA 2000 network (page 3). Mounting the Antenna Under a Surface Notice Before attaching the under-deck mounting bracket to the surface, verify that the supplied screws will not penetrate the surface. If the supplied screws are too long, you must purchase surface-appropriate screws to complete the installation. Because the antenna cannot acquire signals through metal, it must be mounted under a fiberglass surface only. 1 Determine and test the location under a fiberglass surface where you want to mount the antenna (page 1). ➊ ➋ ➌ 2 Place the adhesive pads ➊ on the under-deck mounting bracket ➋. 3 Place the antenna in the under-deck mounting bracket. 2
