Introduction 1 Overview • • • • • • The HS70 is a complete GPS compass and positioning system in a single enclosure that requires only one power/data cable connection. With its NMEA 2000 and NMEA 0183 support and ease of installation, the HS70 is the perfect solution for marine applications.
Installation 2 Mounting Location This section provides information on determining the best location for the HS70.
HS70 Alignment The top of the HS70 enclosure incorporates sight design features to help you align the enclosure with respect to your vessel. To use the sights, center the small post on the opposite side of the enclosure from you, within the channel made in the medallion located in the center of the enclosure top as shown in the figures below. Alignment accuracy when looking through the long site is approximately +/- 1° Alignment through the short site is approximately +/- 2.
Note: You do not necessarily need to orient the antenna precisely as you can enter a software offset to accommodate for any offset in heading measurement due to installation. Before fix mounting the HS70 • • • Choose a location that meets the mounting location requirements Use the mounting template, mark and drill the mounting holes as necessary for the mounting surface Attach the cable to the HS70 and secure the cable Fix mounting the HS70 1. Mark the mounting hole centers on the mounting surface. 2.
Connecting the cable 1. Align the cable connector keyway or the NMEA 2000 adapter with the HS70 connector key 2. Rotate the cable ring clockwise until it locks. The locking action is firm, but you will feel a positive “click” when it has locked 3. Securing the cable Ports NMEA 2000 Port Powering the HS70 when used in a NMEA 2000 installation To power the unit via NMEA 2000 connection, follow the standard procedure for powering of a NMEA 2000 network.
Power/Data Cable Considerations The HS70 uses a single 15 m (49 ft) cable for power and data input/output. The receiver end of the cable is terminated with an environmentally sealed 12-pin connection while the opposite end is unterminated and requires field stripping and tinning. Depending on the application and installation needs, you may need to shorten this cable.
Default Parameters The table below provides details on the default port settings, available baud rates, differential age, elevation mask, and default differential mode.
3 Operation GPS Overview For your convenience, both the GPS and SBAS operation of the HS70 features automatic operational algorithms. When powered for the first time, the HS70 performs a “cold start,” which involves acquiring the available GPS satellites in view and the SBAS differential service. GPS Operation The GPS receiver is always operating, regardless of the DGPS mode of operation. The following sections describe the general operation of the HS70’s internal GPS receiver.
The heading arrow located on the bottom of the HS70 enclosure defines system orientation. The arrow points in the direction the heading measurement is computed (when the antenna is installed parallel to the fore-aft line of the vessel). The secondary antenna is directly above the arrow. Note: The HS70 moving base station algorithm only uses GPS to calculate heading. Differential corrections are not used in this calculation and will not affect heading accuracy.
4 Troubleshooting Sympton Possible Solution Receiver fails to power • • • • Verify polarity of power leads Check integrity of power cable connectors Check power input voltage (6 to 36 VDC) Check current restrictions imposed by power source (minimum available should be > 1.
