Default Seatalk NG Power pins on i50 display?

Hi,
Which are the 12V power and return pins on the Seatalk-ng connectors on the i50 display? Say when looking at back of the display, moving counterclockwise from the top, starting to left of the alignment key.

I'm trying to connect power to an i50 Depth display with the cable supplied with the display, but it looks like they expect a ST-ng bus kit is in place and I don't want to add the complexity when I only need 12V, So I plan to breakout the red and power wires in the A06049 cable supplied. This cable consist's of the 3 pin ST connector, short 3 wire cable, connected to the 6 pin ST-NG connector.

Does anyone have a schematic for the cable?

Any help or thoughts? Thanks

Best to get a Seatalk NG starter kit part number, T70134 you need to have a balanced NG network for things to work correctly.

Hi,
I don't want to install a network, just power the display. So I don't have a need to balance when there is no network. I'd just like knowing I have power on the correct pins.

You also need to know how to terminate the network correctly, unless you have this knowledge I recommend you to build a complete network.

There is no need to create a network to power a display. Termination is only needed for impedance matching of data lines with high speed signals , not DC voltage. All I am looking for is a verification by someone familiar with the pin out of which pins on the 6 pin Seatalk NG connectors are the +12V and 12V return. RayMarine just wants to sell hardware and not share details.

It's the red and black wire in the seatalk ng cable . If you have a seatalk ng cable to cut. The white and blue are data. It may have an unneeded yellow for seatalk 1
