Ok, I've got the resistor wired in now and I'm still getting the same issue. I am now getting periods of 'led off' which I've not seen before, the data comes through very slowly, I've seen 8 fields appear after some time, however the values don't really change. I've tried resistor values 4K7, 2x 4K7 in series and then 3x 4K7 in series. I get slightly more data not inverted than I do inverted but its still basically the same as very slow and not complete.
Thank you very much for your help with this. We have a new MacArthur HAT v1.1. Almost everything worked fine in version 1.0 and only the seatalk1 feature needed some additional work. We think seatalk1 should work for everyone in v1.1 out of the box.
This time only a few units have been made for the people who provided some feedback on seatalk1. Would you like to get the new board for free and help us close this issue too?
Also small bugs have been fixed, applied some design suggestions from the testers and changed some connections so that the different wiring modes are more consistent.
We will also send you the new documentation with all the changes.
Yes, more than happy to continue to test. Very excited about V1.1. Have been using the V1.0 HAT now for a little while and everything other than the seatalk1 link has just worked.
I will respond to your email. Look forward to testing it.

Hi All
Apologies that it's taken me a little while to install the new card.
I'm on the boat today and doing the testing. Just to recap, I have the power option.
I've wired the board as per the new documentation and keeping it simple, I just have the SeaTalk 1 (yellow data cable ) connected.
Unfortunately, I now how nothing coming through in Signal K for the SeaTalk network. I've checked the configuration to make sure that the GPIO settings are correct and I've tried it with the invert signal set on and off.

sorry my last message was a little confusing. What I meant was that I hadn't connected anything else to the card other then the SeaTalk One network. (re: my comment about the yellow data cable).i.e. I hadn't connected up the CAN bus, etc
As for the wiring, it's exactly the same as the documentation. The 12v is connected directly to the battery, GND is connected to my main neg bus bar. I have a 12v switch wire connected on the Seatalk One interface next to the yellow SeaTalk data cable.
My SeaTalk instruments - Autohelm - Depth - Wind are all running from a separate switch on my panel.
I can't see any yellow LED blinking
I'm also not getting the SeaTalk link error that I previously had on the autohelm
