CONTENT

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

FOREWORD

2. Wiring2.1 Input wiring The Output signals from the Synchro or Stepper are required to be connected to the

relevant inputs of the Gyro to NMEA Convertor, refer to the Gyro manufacturers

handbook if required.

6

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.
