GNSS DOPs
Provides a single transmission
containing GNSS status and dilution
of precision components (DOP) that
indicate the contribution of satellite
geometry to the overall positioning
error. There are three DOP parameters
reported: horizontal (HDOP), Vertical
(VDOP), and time (TDOP).

Powering the HS80/MX575C
Power considerations
For best performance use a clean and continuous 12-24 VDC power supply. The HS80/
MX575C power supply circuit features reverse polarity protection but will not operate with
reverse polarity.
See “Power” on page 34 for complete power specifications.
Connecting to a power source
¼
Note:
This section refers to powering the MX575C unit via the serial cable connection. The
HS80 power is taken from the NMEA 2000 main buss. Follow the standard procedure for
powering up via NMEA 2000.
Before you power up the HS80/MX575C you must terminate the wires of the power cable as
required. There are a variety of power connectors and terminals on the market from which to
choose, depending on your specific requirements.
Warning: Do not apply voltage higher than 36 VDC. This will damage the receiver and void the
warranty.
To interface the HS80/MX575C power cable to the power source:
•
Connect the red wire of the cable’s power input to DC positive (+)
•
Connect the black wire of the cable’s power input to DC negative (-)
The HS80/MX575C will start when an acceptable voltage is applied to the power leads of the
extension cable.
Electrical isolation
The HS80/MX575C’s power supply circuit 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).
