[LW] [LW11] Ray 240 VHF with e120W

Dear Bdfritz,

Thank you for your post.

What is the indicator LED status on the ST1 to Stng convertor block displaying?

Has the STng backbone got its own 12v power supply or is it being powered from the SPX course computer?

You need to modify the ST1 to STng adaptor cable, currently it is carrying 12v to your Ray240. You need to snip the cable in half, rejoin the yellow to yellow and screen to screen with the red taped safely back. With this modification you will only be transferring seatalk data and not sending a positive supply to the radio. Is the GPS now available on the Ray240?

Many Thanks
Louise
