Figure 3-24 ACU Cable Connection (BUC Capacity: ACU supplies the BUC Power)
3.6.3 ACU Gyro Compass Cable Connection
The KA-160 ACU will accept Synchro, Step-by-step, and NEMA interface data for a
Gyro compass connection.
The ACU is configured with a terminal strip and a DB-15 port. Care must be taken
when completing these connections. These wires may conduct high voltages and can
damage equipment and/or cause personal injury.
For the synchro and step-by-step gyro inputs, the installer must enter the ship’s heading
information for proper operation. Also, it is recommended that a validation test be
conducted to determine whether the proper heading updates are being received on the
ACU screen.
If the ACU heading is being updated in reverse, the ACU can be modified to change the
polarity of the incoming voltage.
3.6.3.1 Synchro-Type Gyro Connection
In the case of the synchro-type gyro, use the 5 pins (R1, R2, S1, S2, S3) of the DB-15
