Connecting the Sine/Cosine Interface

(Optional)

The GyroTrac ADCU sine/cosine interface provides the following

outputs:

• sine

• cosine

• inverse sine

• inverse cosine

• reference voltage

Because the reference voltage is a reference output, not an input,

connecting this output to another reference output from an

autopilot or other system will cause problems.

In this case, connect the following wires from the autopilot (or

other system) to the green ADCU terminal strip connector:

Autopilot/Other System Wire Terminal Connector

Sine 12

Cosine 10

Internal Power Ground 7

(not chassis ground!)

Reference (INPUT) 8 (KVH Output)

DO NOT connect the autopilot or other system to the ADCU reference

output (ADCU terminal 8) if the autopilot has its own internal

reference. Review the user’s manual for the selected equipment.

Wiring Arrangement

Before connecting the Autopilot

internal ground to ADCU terminal 7,

use a low impedance voltmeter to

make certain that there is no DC

voltage between the two terminals.

A DC surge could damage one or

both systems.

The sine/cosine reference voltage is

an OUTPUT, not an INPUT.

Connecting this output to the

reference output for an autopilot or
