NMEA to Multiplexer to Yeoman Connection
Help please
I have a Ray marine set-up C120, Auto pilot SG3 etc, I have just bought a shipmodul NMEA multiplexer and a Yeoman at the boat show, I started reading all the manuals and have gone into info’ overload. Can anyone direct me to a schematic on how to get these talking to each other and where on the existing system I can get a NMEA feed from and back into it. Is there any pc software that makes use of NMEA information and displays, I am already running maptech. Much appreciate the help in advance. |

But first I need to know the type of multiplexer oyu bought, a -41 or -42, serial, USB or Bluetooth? What will be the function of the C120? Are you going to use the PC as primary navigation system?

Hi Meindert
The multiplexer is 42 BT The ps is secondary navigation for AIS and night time use / back up, I want to be able to click on the yeoman and load a track and it appear on the C120. I would also like to see radar on the pc? Very very grateful for your assistance. Regards |

There's only a few ways available to you in getting a full radar display on your PC, and NMEA ain't it... 1) Koden (resold by Nobeltec, SciTex) 2) Furuno + Maxsea 3) Raytech with HSB-2 interface You can get MARPA targets and a lollipop transferred thru NMEA, but that's probably not what you're looking for. For now, given your self-proclaimed info overload, I would forget about this. -- Kees |

You need a single NMEA - Seatalk and a single Seatalk - NMEA conversion somewhere. For reliability I would use the NMEA input and output offered by your S3G course computer. You haven't mentioned what brand of GPS you have. Assume it's raymarine, then the desired picture is: S3G NMEA out - 42 BT input 1 Yeoman out - 42 BT input 2 42 BT output 1 - S3G NMEA in +- Yeoman in 42 BT on Bluetooth -- PC Have fun, Kees |

I understand the 42 BT can convert seatalk to NMEA on inputs 4a 4b, so I was hoping someone might of already gone through the pain to get the best result for the set-up. Could I ask Meindert if he agrees this is the way to get the best out of the 42 BT? I've got the feeling your solution is the right way Kees, thanks again. Regards |

: Following Kees suggestions I have the yeoman working and have data, but I can't send waypoints to the chart plotter from the yeoman, also I don't seem to be able to benefit from data for winchart on my pc? My Yeoman XL pinout data shows: Data Spec NMEA 0183 4800 Baud 8 Data No parity 1 stop NMEA 0183-1 As NMEA 0183 (Adds 100 to waypoint number on output) NMEA 0183-2 As NMEA 0183 (Adds 200 to waypoint number on output) NMEA 0182 1200 Baud 8 Data (MSB set to 1) Odd parity 1 stop Navstar 2000 110 Baud 8 Data No parity 1 stop These are the speeds it runs when it is set to the various output data streams. Make sure your multiplexer and chartplotters are set to the correct speeds to receive it. Mine wasn't and it took a while. I had to slow the whole boat's 0183 data streams down to 4800 baud, 8-N-1 just to get it all to listen to the slow Yeoman data stream to get waypoints. It won't run 9600 baud, darn it... At 4800 the system seems to be plenty fast..... Your Yeoman manual shows how to switch output data streams between these. Ours is set to 0183-1 adding 100 to the waypoint number so I can see on the chart plotters and computer all waypoints in the 100 range came from the Yeoman, not the plotters or computer. Reduces (but doesn't eliminate, of course) confusion....sort of....(c; Another Yeoman issue is: Voltages O/P voltage TTL levels (0-5V) Sources 50 mA Don't hook it anyplace else but the multiplexer or the TTL voltage will suffer driving two loads. It'll only put out 50ma...output. System: Raymarine RL70CRC-H radar display/chart plotter w/Seatalk gyro-compass, WAAS-GPS, (compass normally off NMEA bus) Garmin 185 chart plotter/sonar (backup GPS normally off NMEA bus) Noland NMEA 4-port multiplexer Icom M-602 VHF DSC Icom M-802 HF-SSB-DSC B&G "Network" (NMEA 0183) instruments, Pilot, Data display, compass sensor (better than Raymarine's) Yeoman XL boards removed from portable foam lap board and mounted to bottom of mahogany chart table top to energize chart table....firmware upgraded... Let me know if you want to know what I did to get the Yeoman to work under the chart table. Works great without the Yeoman's workspace cluttering up the place...(c; -- Larry - 3rd mate, engineering S/V "Lionheart" (Amel Sharki 41 ketch) Charleston It's not mine but I get to play with it when the head is stopped up....(c; |

Hi 'autopilot', I'm haven't tried sending waypoints _to_ the Yeoman; I use mine only to send waypoints from Yeoman to GPS, does that work? I guess one problem would be what the name of the waypoint would be, as the Yeoman only has numeric waypoint ID's, and formatted z9999 as well (eg. 00001, 00002 etc.) if I remember correctly. I also don't understand what you're trying to accomplish specifically with Winchart, please elaborate a little. When you do, please also tell us what _does_ work (e.g. do you get GPS data in Winchart? Then at least one direction is OK.) Note that there are many different NMEA sentences; it's like a maze of twisty passages, all different. You may have to experiment with any and all equipment's NMEA sentence settings. -- Kees |
