Sorry not clear enough there: the Navman 3100 repeater has the 
following wires:-
Red: +ve 12v
Black: -ve and common nmea
Orange and Blue: navbus + /- <not used>
White: nmea input 1 - (think I used this one as a logical step)
Yellow: nmea input 2
Green: nmea input 3

No mention in the bumpf of nmea (0183) speed! It can theoreticaly take 
the sentences I am interested in repeating depth (DPT), speed (VHW), 
current set (VDR) and a few others.
There is only the need for 2 listeners - at the moment. The primary one 
is the DSC VHF which is fully functional and the secondary is the 
Navman 3100 repeater which I should like to display as much of the info 
the laptop is getting or producing.
In terms of listeners baudrate the Navman 7200 dsc vhf nmea is 4800 and 
I assume (eek!) that the Navman 3100 repeater is the same.
I will clarify if it is critical which nmea input wire is used for 
discriminating between sentences (maybe picky?) and required rate for 
the 3100.

CNP has the facility to send out instructions to autohelms and the 
sentences are nmea e.g.  BOD, HDG etc.. so thats reassuring.

I should also like to send waypoint and routes to the Garmin via NDC4 
(that may be a hassle switching from nmea to Garmin protocols) from the 
Tosh or maybe to the 3100 repeater if it's more legible and simpler.

That's my wish list! Am I expecting too much?

The paralleling up of listeners is reassuring - I did read it in the 
Actisense stuff now you mention it.

The great thing about this newsgroup stuff is your never alone and your 
experience is very often never unique - especially farting about with 
this sort of gear and not noticing it's going dark through the cabin 
windows! Thanks for the offer of the code translator - I should like to 
have a decko at it to see how it works. Take the pa out of my address 
above if you wouldn't mind.
