KW950E interface negative 35V step Gyro heading to 38400bps $HEHDT

This is a procedure to interface 4 wire negative step at ref. 35V to 38400bps nmea output. I had tested working on a tanker recently with MK37 Gyro compass.
I had study this connection and document down the procedure.

1. Connect step input to SK2, R+  = Ref, S1 = S1-, S2 = S2-, S3 = S3-
2. Link S1+, S2+, S3+ and R+ together
2. Set SW1 to 0000 1010 for 38400bps $HEHDT
3. Connect nmea output to SK3 data output A and B

KW950E interface serial Gyro heading from low speed 4800bps to 38400bps

As this has become a requirement to connect high speed nmea Gyro compass signal to radar. Typical set at baudrate of 38400bps.
KW950E was able to fulfill this requirement. During the interface of C-plath nmea Gyro signal to Sperry marine VMFT radar, we used KW950E to connect input with 4800bps and ouput 38400bps to both radar and both ECDIS.Be very careful, only one setting works with KW950E from NMEA 4800bps to 38400bps. Below were the procedures :
1. Connect 24Vdc into SK1 of KW950E
2. Connect 4800bps $HEHDT into SK5 data input no.2 - A and B
3. Connect data output into SK3 output no.1 - A and B
4. Set SW1 to 0001 1110 for 4800 input, 38400 output and HEHDT
5. Switch on power and you will get to see display blinking, press either increase or decrease to acknowledge the presence of signal input.

Setup completed. Please see attached pictures to see the connection details.
