Mounting the V200n

Continued

Mounting

alignmen

If you have another accurate source of heading data on your vessel, such as a

gyrocompass, you may use its data to correct for a bias in V200n alignment

within the V200n software configuration.

Alternatively, you can physically adjust the heading of the V200n so that it

renders the correct heading measurement or add a software offset.

NMEA 2000
cable
considerations

Before mounting the V200n, consider the following regarding NMEA

2000 cable routing:

Do not

Ensure cable reaches appropriate

power source

Run cables in areas of excessive

heat

Keep cable away from corrosive

chemicals

Run cables through a door or

window jams

Connect to a data storage device,

computer, or other device that

accepts GNSS data

Crimp or excessively bend the

cable

Keep cable away from rotating

machinery

Place tension on the cable

Remove unwanted slack from the

cable at the V200n end

Secure along the cable route using

plastic wrapping

Improperly installed cable near machinery can be dangerous.
