You cannot use the A22164 ST-STng Converter Cable in the manner which you have suggested. Please click here to view a FAQ addressing this subject.

I viewed the FAQ, but still have a question. May I restate my problem? I have the E22158 converter linked to a backbone. I would like to join an ST6001 pilot controller to this network. How is it done?

Should the ST6002 be the only SeaTalk device which additionally needs to be interfaced to the system, then the A22164 ST-STng Converter Cable would be used to interface one of the ST6002's SeaTalk sockets to the yellow SeaTalk socket of the SeaTalk to SeaTalkng Converter.
I have a similar connection question. Sister's boat has an ST4000+ and a new a75 MFD. I have the E22158, so I take it I need the A22164 to connect to one of the ST1 ports on the ST4000+? It would be so much simpler if the a75 had a NMEA0183 connection, like my e7d does. The E22158 has the NMEA cable, but reading the documentation, it doesn't sound like the converter will pass the track, etc., data strings through to the pilot, only location data?
Thank you!
Welcome to the Raymarine Forum brewgyver,

As indicated within the FAQ found here, the SeaTalkng to NMEA 0183 data bridging features of the SeaTalk to SeaTalkng Converter are limited to bridging the data items that would typically be necessary to support the GPS data requirements of a DSC VHF radio. Accordingly, when operating in SeaTalkng to NMEA 0183 mode, the SeaTalk to SeaTalkng Converter will not supply an autopilot with navigational data required to support the autopilot's Track mode feature. As such, a SeaTalk to SeaTalkng Converter would need to be used to interface the MFD to the ST4000+, and the autopilot's SeaTalk rather than NMEA 0183 interfaced would be used. To ensure that SeaTalk bus is being powered by the SeaTalkng backbone (which the SeaTalk to SeaTalkng Converter comprises or is part of), the SeaTalk cable which is connected the ST4000+ should be cut. It's yellow and shield leads would then be sliced back together, leaving the cable red leads cut. The red leads of this cable should then be insulated to prevent shorting. This action will prevent the autopilot's SeaTalk port from supplying power to the SeaTalk bus and thereby permit the SeaTalkng backbone to supply power to the SeaTalk bus.
Hi Chuck, thanks for the speedy reply!
I mistakenly bought the E70196 kit, not the E22158, but they appear to use the same converter, and just have different cables packaged in the kit, so I simply need to get the A06073 cable, disconnect the red (ve+) and connect only signal and shield as discussed, correct?

The SeaTalk to SeaTalkng Converter included with the E70196 VHF NMEA 0183 to STng Converter Kit is identical to that included with the E22158 SeaTalk to SeaTalkng Converter Kit. An A22164 SeaTalkng Converter Cable would be used to mate the SeaTalkng Converter the SeaTalk port of the ST4000+ or to a D244 SeaTalk Junction Block. Using an appropriate length of SeaTalk Cable having press-fit female plugs on each end, the D244 SeaTalk Junction block would then be interfaced to the SeaTalk bus to which the ST4000+ and any other devices having a SeaTalk communications interface have been networked. See my last response regarding cutting and then re-splicing the SeaTalk cable which will be connected to the autopilot's SeaTalk port.
Got it, thank you very much! Six hour drive for this work, so I want to get it right the first time!
You're welcome.
Welcome to the Raymarine Forum LulaNord,

Q1. I think Maretron's field installable DeviceNet M/F plug can be installed on the SeaTalkng backbone cables to permit one end of each cable to be mated to Maretron backbone. Right?

A1. Please click here to view a FAQ addressing this subject.

Q2. Is it true that one needs to cut one end of the SeaTalkng Backbone Cable and field install a Maretron connector?

A2. Yes.
