3. MX575 Operation
The MX575 D/GPS Satellite Compass is powered by connecting the Red (18
gauges) and Black (18 gauges) to an 8 to 36 VDC power source. Once powered,
the MX575 will proceed through an internal start-up sequence, however it will be
ready to communicate within a few seconds.
Typical time to first fix when the unit is first turned on right out of the box is within
1-2 minutes from startup. The SBAS or beacon lock may take several minutes to
acquire from startup.
3.1 MX575 Antenna Cable
The MX575 antenna cable assembly is composed of 7 twisted pairs, only 3 pairs
are used to connect to the MX CDU. The thick Red and Black wires (18-Gauge)
are Power and Ground. The thinner wires (24-Gauge) are signal wires. Unused
wires should be cut and wrapped with electrical tape to prevent accidental contact
with other wires. The standard antenna cable supplied with the MX575 is 15
meters long. For longer cable run, a 30-meter cable can be ordered from your
dealer.
