Navigation Options
The E6474A software supports many navigators. Two
navigation options are available for in-vehicle installations:
• GPS/DR Navigator. See“Communicating with the Agilent
Direct Connect GPS/DR" on page 45.
• Garmin II Plus GPS receiver. An operator’s manual and
interface cable is supplied with the receiver. Connect the
interface cable per the instructions under “Garmin GPS
Receiver Connections" on page 41. The receiver can be
powered by internal batteries or by vehicle power.
Gyro Positioning
To avoid inaccuracies in dead reckoning, the Gyro in the Agilent
Direct Connect GPS/DR must be positioned so that it is within
10 degrees of vertical or horizontal. The Gyro must be set to
indicate the Up position on the unit as follows:
1 Position the unit either horizontally or on its right edge
(vertically).
2 Turn the Gyro Position knob counter-clockwise to loosen it.
3 Slide the pin so that it indicates the applicable Up position.
4 Turn the Gyro Position knob clockwise to tighten it.
