Normal Usage

The G2 Display Head provides graphical and text information about the vessel position and

attitude (speed, heading, turn rate). Two (2) Display Heads can be driven from a single

Distribution Unit.

The G2 display provides three different levels of display pages. The first level pages (DISP

mode) shows information typically used during vessel operation including graphical and text

displays of vessel operation. Pressing the DISP button repeatedly will cycle through the

Display pages.

The second level pages (INFO mode) show more detailed operational parameters such as

sensor smoothing constants, and GPS operational information (number of satellites, type of

fix, etc). Pressing the INFO button repeatedly will cycle through the Display pages.

The third level pages (SETUP mode) allows you to change operating parameters in the

Vector Series GPS compass. Operating parameters include:

• message rates for NMEA messages,

• message rates for binary message,

• sensor smoothing constants,

• sensor bias adjustments, and

• sensor filter aids.

Pressing the SETUP button repeatedly will cycle through a series of setup pages.
