I have an autopilot Raymarine ST4000+ installed on my sail boat and a B&G
Network for speed and wind direction. I'm trying to send the NMEA data from
B&G to the ST4000. On the B&G instrument the output is a simple five holes
DIN connector. I've searched around for the wirings of this plug but it
seems the best kept secret (or I'm getting too old for this stuff).

Where could I find the description of the plug (without having to bring an
oscilloscope in the cockpit)?

Many thanks
Giuseppe

Try or ring 954-229-0208. They should be able to help
you.

You can probably find it or infer it from some of the diagrams at :

Check your email for two pdf files for Adobe Acrobat reader, Guiseppe.
I've sent these diagrams for NMEA connections the data below came from.
Larry


Female Network Connector
Wire Color
Pin 1 - Black - Supply Ground
Pin 2 - Red - +12V supply
Pin 3 - White - B&G Network Data
Pin 4 - Green - NMEA + or Alarm Out
Pin 5 - Screen - Shield

Male Network Connector
Wire Color
Pin 1 - Black - Supply Ground
Pin 2 - Red - +12V Supply
Pin 3 - White - B&G Network Data
Pin 4 - None - No Connection
Pin 5 - Screen - Shield

Notes:
1) The above connectors are found on the pigtails on the back of each
Network display as well as on the display interconnect cables
(p/n's NET-NC1, NET-NC3 and NET-NC9).
2) Pin 4 on the female plug on the display is used for NMEA instrument data
output on the following instruments: Compass, Data,
Speed, Tack, and Wind.
3) Pin 4 on the female plug on the display is used for the Network external
alarm (p/n 617-00-002) output on the Depth and Quad.
4) Pin 4 on the display interconnect cables has no connection on both the
male and female ends.

This is what I copied from the pdf file about Network instrument
connections I use on Lionheart. Each instrument's NEMA data stream comes
out the Green wire but does not connect to the next instrument. I use the
NMEA output wire from our Network Data Repeater instrument at the nav table
to output all the NEMA data from all the instruments into our NEMA network
multiplexer for Wind/Temp/Depth/Compass (from the Network Pilot autopilot),
etc. The Cap'n software hooked via a wireless router to the computer port
on the Noland multiplexer via a serial to Ethernet adapter displays the
NMEA data coming out of the B&G Network system. We have all B&G Network
instruments Wind/Speed/Pilot/Depth/Data on the boat, all daisy-chained
together.

By the way, you can extend the reach of any of these pigtails without
buying expensive B&G extension cables you can't fish through wiring runs
with the damned molded connectors already on them. Just cut pigtail wires
in the middle of them leaving wires on both the plug and the instrument. I
used shielded 6-conductor Belden from Mouser Electronics (www.mouser.com)
to keep my HF transmitter from trashing the data. Foil tape covers the
splices hooked to pin 5, the shield of the Network cabling. Works great.
