Garmin GPS 19x NMEA 2000 Installation Instructions - Page 3

4 Adhere the under-deck mounting bracket to the mounting surface. 5 Secure the under-deck mounting bracket to the mounting surface with screws. 6 Connect the cable to the antenna ➌. 7 Route the cable away from sources of electronic interference, and connect it to your NMEA 2000 network (page 3). Connecting the Antenna to Your NMEA 2000 Network If you do not have an existing NMEA 2000 network, you must install a NMEA 2000 network on your boat. For more information on NMEA 2000, go to www. garmin.com. The antenna is packaged with a NMEA 2000 T-connector and a NMEA 2000 drop cable. You will use these two components to connect the antenna to your existing NMEA 2000 network. 1 Determine an appropriate location to connect the antenna ➊ to your existing NMEA 2000 backbone ➋. ➊ ➍ ➌ ➋ 2 Disconnect one side of a NMEA 2000 T-connector ➌ from the backbone nearest to the location where you want to connect the antenna. If you need to extend the NMEA 2000 backbone, connect an appropriate NMEA 2000 backbone extension cable (not included) to the side of the T-connector you disconnected. 3 Connect a T-connector (included) in the NMEA 2000 backbone. 4 Route a drop cable (included) ➍ from the GPS 19x antenna to the top of the T-connector you added to your NMEA 2000 network. If the included drop cable is not long enough, you can add a drop cable extension up to 13 ft. (4 m). If more cable is needed, add an extension to your NMEA 2000 backbone, based on the NMEA 2000 guidelines. Chartplotter Software To ensure compatibility with the antenna, upgrade your Garmin chartplotter or display device with the latest software. For more information, go to www .garmin.com/support. Configuring the Antenna To access the NMEA 2000 configuration menu on your Garmin display device, consult the documentation provided with your display device. Enabling and Disabling WAAS/EGNOS When enabled, WAAS (Wide Area Augmentation System)/EGNOS (European Geostationary Navigation Overlay Service) provides more-accurate position information. For more information on WAAS/ EGNOS, visit www.garmin.com. 1 While viewing the NMEA 2000 configuration menu on your display device, select the antenna. 2 Select Review > WAAS/EGNOS. 3 On a Garmin chartplotter, select On or Off. About the Speed Filter The speed filter setting on the antenna can help reduce unnecessary drift-alarm triggers as well as potentially sporadic position information. The speed filter averages the data provided by the antenna to provide smoother position data updates. The speed filter is most helpful when stationary or in low-speed situations. Setting the Speed Filter 1 While viewing the NMEA 2000 configuration menu, select the antenna. 2 Select Review > Speed Filter. 3 Choose from the following options: • Off-position information from the antenna is provided to the NMEA 2000 network as it is gathered. • On-position information from the antenna is gathered and averaged before it is provided to the NMEA 2000 network. Select the interval at which the position information is gathered. • Auto-the speed filter toggles on in lowspeed situations and toggles off in high-speed situations. Refreshing GPS Satellite Acquisition In some situations, if you have moved the boat many miles without using the antenna, for example, you can force the antenna to reinitialize and find your current position. 1 While viewing the NMEA 2000 configuration menu, select the antenna. 2 Select Review > Auto Locate. 3 Wait for the antenna to acquire satellites. Restoring Factory Default Settings You will lose all custom configuration settings when you restore factory default settings. 1 While viewing the NMEA 2000 configuration menu, select the antenna. 2 Select Review > Factory Defaults. Enabling GLONASS Satellites You can configure the antenna to acquire GLONASS satellites. 1 While viewing the NMEA 2000 configuration menu on your display device, select the antenna. 2 Select Review > Generic Config. 3 Enter "GLONASS=1;RESET". 4 Select Done. The antenna resets. Disabling GLONASS Satellites 1 While viewing the NMEA 2000 configuration menu on your display device, select the antenna. 2 Select Review > Generic Config. 3 Enter "GLONASS=0;RESET". 4 Select Done. The antenna resets.  3
