IMPORTANT: Please read the Owner’s Guide completely before proceeding. Introduction Thank you for purchasing the Airmar’s GPS Receiver and combined antenna. This sensor fixes position using Wide Area Augmentation System (WAAS). The compact housing is waterproof with a single removable cable. Data is output in digital NMEA 0183 and NMEA 2000® formats.
WARNING Navigation Aid Only: The sensor is only an aid to navigation and should never be solely relied upon. It is not a replacement for traditional navigation aids and techniques. Only official government charts contain all the information needed for safe navigation. Follow the safety precautions below to reduce the risk of poor product performance, property damage, personal injury, and/or death. WARNING: GPS Accuracy The GPS position and velocity accuracies are controlled by the U.S.
Cables & Connecting/Converting Hardware The GPS Receiver (sensor) can be connected in several ways. You must have the correct cable and any needed converting/connecting hardware before beginning the installation. Sensor Cables • NMEA 0183 Cable • NMEA 2000® Cable • NMEA 2000® Cable NOTE: Additional cable lengths are available.
Choosing the Mounting Location For a reliable GPS signal, selecting the best location for the sensor is very important. It can be mounted on a pole, rail, or flat surface. Choose a location that balances the requirements below. • The sensor must have a clear view of the sky to the horizon in all directions to receive satellite signals. Be sure there are no obstructions from buildings, boats, etc. However, the lower it can be mounted, the more stable it will be.
Installing CAUTION: Be sure to use the correct parts for your installation. Do not use the flush mount parts (gasket, part B) to mount the receiver on a pole. Using the wrong parts may allow water to leak into the unit. CAUTION: If you use a thread locker, use teflon pipe thread tape. Do not use a liquid thread locker as it may weaken the plastic, causing it to swell and crack. IMPORTANT: Plan the cable route between the sensor and the display and/or network before beginning the installation.
2. Decide if you want the cable to exit through the center or along the side of the pole/rail bracket. Slide the nut assembly onto the cable at the sensor connector. Do not connect the sensor at this time. a. Center exit—Pass the instrument connector end of the cable through the center of the pole. Be sure to leave several inches of cable extending beyond the nut assembly. b. Side exit—Place the cable side-exit adaptor (part D) over the cable.
Flush Mount 1. Remove the label from over the sensor unit’s socket (see Figure 3). Apply removable thread locker to the two studs supplied. Screw the studs into the underside of the sensor unit (part A). 2. Using the gasket (part B) as a template, position it at the selected mounting location upside down with the arrow facing forward. Mark the position for the two mounting holes and the center hole for the cable. 3. Using a 3mm or 1/8" bit, drill the pilot holes.
Cable Routing & Connecting Depending on the equipment you will be using, route the sensor cable to an Airmar Data Converter, Combiner, an NMEA 0183 display, an NMEA 2000 network, a laptop, or other device. After reading the cautions below, go to the appropriate instructions. CAUTION: Do not remove the waterproof connector(s) to ease cable routing. Buy a cable without a connector. Instructions for wiring are supplied.
No Connector on Display End: Wiring If your sensor cable does NOT have a connector on the display end, it must be hard wired. Referring to the owner’s manual that came with your display, connect the colored wires as show in Figure 4. CAUTION: Your sensor has either an RS422 or RS232 interface. You must follow the wiring diagram in Figure 4 that matches your sensor. If it is wired for the wrong interface, it will not transmit and receive data properly.
Connecting to an NMEA 2000® Network CAUTION: Only two termination resistors are required on an NMEA 2000 network. More than two will degrade the bus performance. Route the sensor cable to the NMEA 2000 network. Plug the NMEA 2000 connector into the network node (see Figure 5). Coil any excess cable and secure with cable ties to prevent damage. locator 10 sensor connector NMEA 2000 network connector 10 Figure 5.

Maintenance CAUTION: Do not disassemble the sensor. Removing the screws from the sensor unit (part A) will damage the waterproof seal, thus voiding the warranty. CAUTION: Do not immerse in water or pressure wash. Doing so may allow water to infiltrate the sensor, voiding the warranty. Since the sensor has no moving parts, it requires minimal maintenance. Clean with a soft damp cloth and mild household detergent.
