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.

Connecting the Speed Pulse

When connecting the Speed Pulse cable, the following wiring

scheme is used:

Figure 24 Setting the Gyro pin. If the unit is set on its right side, the pin is set at the alternate position.

CAUTION

The dead reckoning system is comprised of the Gyro and the Speed

Pulse (odometer) connection. The connection of the Speed Pulse cable

is vehicle-specific and should be performed by persons trained to do

such installations.
