that are sent by the multifunction display to any devices
connected the NMEA output port.
Enables you to specify the appropriate port speed for the
equipment connected to NMEA Input port 1. Use the AIS 38400
option for AIS receivers.
Enables you to specify the appropriate port speed for the

Description
Determines how all bearing and heading data is displayed in.
This does not affect how the chart or radar displays are drawn.
This setting compensates for the naturally occurring offset
of the earth's magnetic field. When set to Auto, the system
automatically compensates, and displays the compensation
value in brackets. To enter your own compensation value, use
the Manual option, then specify the value using the Manual
Variation setting (see below). This value is also transmitted to
any other connected Raymarine instruments.
When the Variation Source menu item is set to Manual (see
above), you use the Manual Variation setting to specify the
compensation value that you want to use.
In order for your GPS receiver and multifunction display to
correlate accurately with your paper charts, they must be using
the same datum.
The default datum for your multifunction display is WGS1984. If
this is not the datum used by your paper charts, you can change
the datum used by your multifunction display.
When you change the datum for your multifunction display, the
chart grid will subsequently move according to the new datum,
and the latitude / longitude of the cartographic features will also
change accordingly. Your multifunction display will attempt to set
up any GPS receiver to the new datum, as follows:
• The internal GPS receiver will automatically correlate each
time you change the datum.
