HSC100 Quick Start Guide
3. Installation
Before starting installation select a suitable
location for the HSC100 Sensor. The ideal
position for a fluxgate compass sensor is in the
centre of the boat where pitch and roll is
minimised.
The HSC100 should also be mounted as far
away as possible from metal objects that are
regularly moved or electrical cables/equipment.
Effects from fixed metal objects can be
calibrated out, but if a metal object is placed
near or moved away from the sensor after
calibration, inaccuracies could occur.
The HSC100 should be fixed to a vertical
bulkhead in an upright orientation using the
fixing holes shown in the diagram. It does not
matter which direction the HSC100 faces, as
the azimuth can be set to North at any time.
4. Electrical Connections
The HSC100 is supplied with 15m of cable and this should be routed through the vessel to a suitable dry internal location
where it can be connected to the
boat’s DC power system and the equipment it will be interfaced with. The cable can be
shortened, lengthened or joined without problems.
The HSC100
should be connected to the boat’s DC supply via a 1 Amp fuse. The unit requires 8V to 30V DC supply
voltage. Typical supply current during operation is approx. 25mA. Note that the operation of the LED adds another 10mA
and that during auto-calibration the consumption can be as high as 60mA.

The HSC100 can provide compass data in two industry standard formats; NMEA0183 and Furuno AD-10 format. The
following section explains these two formats.
