[CA] Splice SeaTalk1 to SeatalkNG

HI,

Im doing restoring a network, after damages in huricane, and one of my question is, I lost seatalk to seatalkNG cnoverter cable (yellow Plug), but i should be able to splice piece of of standard STng and seatalk1 cable with plug.

i done this:

seatalk1 RED to seatalkNG RED
seatalk1 SHIELD to seatalkNG Black
seatalk1 YELLOW to seatalkNG YELLOW

SatlakNG Shield not connected
SeatalkNG Blue not connected
SeatalkNG White not connected

Such spliced cable go betwen SmartPilot Course Computer and Yellow socket on STng coverter.

In my opinion all should work, I got Power On converter block, but no data is going Between SeaTak network where is only Depth and Autopilot and SeaTalkNG.

Converter socket are:
1. Blue - Terminator
2. White - Axiom Chart plotter connected by STng-N2K cable
3. Yellow - With spliced cable like above
4. White - Actisence N2K to nmea0183- thru STng to N2k cable, NMEA0183 to Si-tex radar
5. Blue - terminator

But i dont have reading of depth on Axiom Plotter, and Axiom pointed waypoint are not transferred to course computer. Axiom pointed way point is transferred properly to Si-tex radar screen by Actisense N2k-NMEA0183 gateway.

Should such configutration should work. What could be a problem, should i splice shield from stNG cable to black and to shield on SeaTalk1?

Please Help did i miss somethink, or axiom will not comunicate that way with S3 Smartpilot??
