Page 5: Introduction
INTRODUCTION Overview The HS75 GNSS compass supports GPS, GLONASS, Galileo, QZSS, and BeiDou satellites. The HS75 GNSS antennas are separated by 20 cm (7.87”) between phase centers, resulting in a heading performance of better than 0.75° RMS. The HS75 can provide heading and positioning updates at 10 Hz and delivers positioning accuracy of 0.6 m 95% of the time when using differential GPS corrections from Satellite Based Augmentation Systems (SBAS). -
Page 6: Installation
INSTALLATION Wiring guidelines Before mounting the HS75, consider the following regarding the NMEA 2000 cable routing: ® • Avoid running the cable in areas of excessive heat. • Keep cable away from corrosive chemicals. • Do not run the cable through door or window jams. •... -

VHF interference VHF interference from cellular phones and radio transmitters may interfere with GNSS operation. VHF gain pattern GNSS gain pattern VHF antenna HS75 Minimum horizontal spacing: 2 m (6.5 ft). Minimum vertical spacing: 2 m (6.5 ft). Minimum cable separation: 0.3 m (1 ft) for the first 5 m (16.5 ft). Mounting orientation Mount the HS75 parallel to, and along the centerline of the axis of the boat. -
Page 8: Mounting Options
You can enter a heading offset from a compatible display unit. You will have an offset in the pitch/roll output if the unit is not installed on a horizontal plane. Alignment The top of the enclosure incorporates sight design features to help you align the enclosure with respect to the vessel. - Page 9 Surface mounting with adapter Secure the upper adapter to the HS75 using the supplied mounting hardware. Tighten to a torque of 11 - 13 Nm (8 - 10 lbs-ft). The maximum thread depth engagement must be no more than 12 mm (0.50“).
- Page 10 Pole mounting Screw the jam nut onto the 1-inch pole, then screw the pole mount bracket onto the pole. Do not tighten the pole mount to more than 5.4 Nm (4 lbs-ft). Feed the cable either through the hollow pole or through the opening in the pole mount bracket. Connect the NMEA 2000 drop cable to the HS75, then secure the pole mount bracket to the ®...

Wiring The HS75 has a standard NMEA 2000 Micro-C connector, used for both power and data ® communication. Purpose Shield NET-S (+12 V DC) NET-C (DC negative) NET-H NET-L Electrical isolation The HS75 power supply is isolated from the communication lines and the PC-ABS plastic enclosure isolates the electronics mechanically from the vessel (addressing the issue of vessel hull electrolysis). -
