MX575A/B DGPS Compass
23
If you have another accurate source of heading data on your vessel, such as a
gyro compass, you may use its data to correct for a bias in MX575
alignment
using the MX CDU configuration. Alternatively, you may wish to physically adjust
the heading of the MX575
so that it renders the correct heading measurement,
however, adding a software offset (see pgs. 35-40) is an easier process if use with
an MX420/2, MX420/8 or MX420/AIS CDU.
2.3 Connecting to a Power Source
The first step to powering the MX575 is to 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 from, depending on your specific requirements.
Caution: Do not apply a voltage higher than 35 VDC as this will damage the receiver and void
the warranty.
To interface the MX575 power cable to the power source:
•
Connect the red wire (18 gauges) of the cable’s power input to DC (+)
•
Connect the black wire (18 gauges) of the cable’s power input to DC (-)
The MX575 features reverse polarity protection to prevent damage if the power
leads are accidentally reversed. The MX575, however, does not function with
reverse polarity.
Once the MX575 system has been installed, you’re ready to turn the system on by
applying power to it. The MX575 will start when an acceptable voltage is applied
to the power leads. Be careful not to provide a voltage higher than the input range
as this will damage the MX575.
