[CA] [CA11] ST4000+ Drive Power Supply

[[email protected]]

Hello,

Currently my ST4000+ has a 12V connection and the drive motor is powered from ST4000+.

I am reconfiguring my system to add SeaTalkNG network.

Can ST4000+ be powered from SeaTalkNG and still provide power to the drive., or should the ST4000+ be directly connected to 12V power supply so that the drive is not getting power from SeaTalkNG?

If I have to connect 12v power directly to St4000+ and still communicate on SeaTalkNG then I would have to remove power from the spur cable to ST4000+. What is the detailed procedure for this? The SeaTalkNG will already have a power supply.

I've attached an image of my proposed configuration.

Thanks!

Andy

Welcome to the Raymarine Forum Andy,

Q1. Can ST4000+ be powered from SeaTalkNG and still provide power to the drive.,
A1. Negative. The ST4000+ is neither designed be powered by a SeaTalk bus, nor a SeaTalkng backbone.

Q1b. should the ST4000+ be directly connected to 12V power supply so that the drive is not getting power from SeaTalkNG?
A1b. Affirmative. Additionally and as indicated within the FAQ on this subject, the red lead of the SeaTalk Cable connecting the ST4000+ to the SeaTalk bus / SeaTalk to SeaTalkng Converter should be severed and then insulated to prevent shorting.

Q2. If I have to connect 12v power directly to St4000+ and still communicate on SeaTalkNG then I would have to remove power from the spur cable to ST4000+. What is the detailed procedure for this? The SeaTalkNG will already have a power supply.
A2. Please refer to the FAQ referenced within the response to Q1b.

Q3. I've attached an image of my proposed configuration.
A3. No configuration diagram has been attached to your thread. Should you desire for it to be reviewed, please attach the diagram to a follow-up post to this thread.

Hi Chuck diagram attached. I have not drawn the power supply to ST4000+.

Hope all looks I start my install this weekend!

Andy,

The diagram appears to be correct in all but the following aspects:

- the i60 Wind is shown connected to a backbone (blue) socket ... should be connected to a spur (white) socket.

- shift the SeaTalkng Power Cable to the other side of the 5-Way Connector to create a more balanced LEN load.

- annotate the diagram with my comments addressing how the ST4000+ should be interfaced to the SeaTalk to SeaTalkng Converter.
