SeatalkNG to S1 course computer

[57BlueWolf]

Thank you for your assistance. I have done as you suggested, and now it seems the Control Head does recognize the Course Computer and gives me a heading. I still have 2 issues:
1) The Control Head beeps continuously with RUDDER REF as the message. Do I need to restore the factory resets to overcome this? I was not planning to use a Rudder reference and I understood I did not need to - am I correct?
2) Neither the i70 or the MFD recognize the Pilot - is that related to 1) above, as the Pilot is not yet fully functioning?
Many thanks again for your patience and assistance.
