[CA] Adding STNG and N2K to exisiting Seatalk

[Grantj]

Chuck, thanks for the quick response.

Thanks for clarifying that the C-120's ST port does actually output 12V onto the buss - I have received conflicting information on this. I have an unused R55006 Junction box, that I think I could use to break out the red power leads from each MFD, and combine the yellow/drain wires together to make a single SeaTalk connector to the E25049 5-way block. Does this sound acceptable?

I understand the SeaTalk-SeaTalk NG convertor does NOT support data bridging of AIS data from the STNG buss to the ST bus. Fortunately the Em-trak B300 unit has both N2K and NMEA 0183 outputs, as well as multiplexing capability, so I should be able to get the 0183HS data directly to both C-120's NMEA ports, as well as on to the N2K network for translation by the Actisense gateway as well. At least, that's the plan.

If I buy a new E22158 kit, wouldn't it automatically ship with the latest firmware? I know I can't update it from a C-120, which is unfortunate... how do I confirm the firmware version before I leave the store??

Also - does RM publish a list of approved PGN-Seatalk sentences that are supported over the SeaTalk-SeatalkNG convertor yet? If not, is that in the works, or are they intentionally withholding that information?

Finally - having a difficult time getting the software upgraded to 5.16 on the C-120's, using a 8MB Compact Flash card, cleanly formatted as FAT, and just the two .DOB and .pkg files in the root directory. Is there any reason this shouldn't work? I got two blue screens and gave up... (see attached)

Thanks for all your help!
