Thanks for choosing Onwa KGN-200 Gyro to NMEA Converter. KGN-200 convert
the traditional gyro synchro and stepper signal into digital NMEA0183 signal and
display the heading in real time. It can provide NMEA0183 digital signal to various
equipments onboard such as ECS, Radar, AIS and Autopilot.
Before you start please make sure the package included the following items :
1) KGN-200 Main unit One set
2) Operator manual One copy
3) Input /Output connectors One set
4) Installation materials One set

Working with Stepper gyrocompass make connection of S1, S2, S3 and COM
to corresponding gyrocompass output. No connection for R1 and R2
Working with Synchro gyrocompass make connection of S1, S2, S3, R1 and
R2 to corresponding gyrocompass output. No connection for COM
Note: When heading indicator on KGN-200 is running opposite direction against gyrocompass heading you just require reverse the connection either 2 wires of
S1, S2 or S3.

OPERATION
There are 3 keys on the operator panel, , and .
1) Check all switches are correctly set, Sync/Step, Com +/Com-, Transmission ratio.
2) Check the output wires are correctly connected , RS422 RS232 AD-10.
3) Check S1 S2 S3 COM For Stepper or S1 S2 S3 R1 R2 For Synchro
are correctly connected. You will find the LED on the panel is flashing.
4) By using , keys to get same heading display on LED and gyrocompass.
5) Press once to confirm and you will find LED stop flashing. The heading
display on LED is synchronized with gyrocompass.
6) At that time you can check the setting by pressing key. Rnnn where
R=Transmission ratio and nnn is ratio setting.
7) If you want to re-adjust the heading display on LED, follow the steps
Press and hold key for 3 seconds, the LED start flashing
Press or to adjust the heading
Press to finish the adjustment
8) Press to increase the intensity of LED and to decrease the intensity.
