In Topic: Ventus PRO is now available

19 April 2013 - 04:45 PM

Version 8.7.3 of Expedition has been updated to setup all the communications to Ventus Pro with a single command.

This include the 16 values that are essential for the START to work.Plus a further 31 useful values to display on various VENTUS screen.

 

Menus: Instruments/Network 0/Expedition/Expedition Settings  > Ventus  !

 

Great. thanks Nick.


In Topic: Nexus FDX server NMEA input....

18 April 2013 - 12:24 PM

Yep, got that. What I thought,  on single logical input. My server manual is 2002 and there are a few print errors. (ie pins 9&10 for nmea input!)

Trouble is,  I am half way over to n2k. Compass & gps.

I will set the compass to 1htz & try again. Then mux with gps & try that.

Woolfy's  out. (His 1/2day)

 

"The latest 6 axis compass sits in parallel with the displays" ?  and is connected to what pins or via pc?

Some subtlity here.... new wind is connected to log?

Sorry you've lost me.

Cheers for your thoughts.

 

 

 

 

if i don't miss my guess, maretron is n2k standard and nexus server is only nmea183?

Maretron SSC200 is both. And data is currently showing on a non-nexus 0183 display..

 

OK,
Nexus re-engineered a lot of their sensors two or 3 years ago. 
These are used  on both NX2 and NXR so they need to have "added value" functionality;  
and (given the inexorable march of Moore's Law** ) both memory and intelligence is incredibly cheaper now  than whenever they designed the server.
 
They choose to put lots of intelligence into the sensor heads for the new wind, GPS and gyrocompass . 
 
This had the advantage for the users that we could keep our existing server and instrument heads and  incrementally improve the system.  
 
The new smart instruments needed to interface 
to a digital bus and, perhaps luckily, the data bus used for the display instruments was suitable. So now when you install one of these "nSensors"
you connect it in parallel with the instruments.
 
All seems to work though sometimes I wonder if it is really a good idea to have all the wind calculation stuff at the top of the mast:) 
 
(I guess at some point soon they will have to junk the whole lot and switch to 
a new server supporting NEMA2000 and compatible with all the Garmin stuff.)

Pukka
On the nx2 server pins 10 and 11 are a single logical input. Manual section 2.7 should help you here.
Nexus's own compasses have separate inputs, my old compass used to connect to dedicated pins 9-12. The latest 6 axis compass sits in parallel with the displays and the new wind sensor on the data bus pins 5 to 8.

If you do use the pins 10 and 11 for the compass, then you need to get GPS data into the system , there are several ways to do this. Have a look at the 5 hz GPS thread on the forum or mail Woolfy .

How this helps.

Harry ,
Nick has been helpful with this, I will copy you some emails you have not had.

1. A problem that was preventing further testing has been resolved on his advice to use EXP system restore to delete
The previous exp display states . Nick tells me that it is not an winxp / win 7 version issue.
He is also enabling me to run a parallel Exp test on a desktop pc to try and eliminate any poss.
Problems . Am waiting for a code from cmap before I can run the parallel test.

I Have made a fairly rigorous check list to go thru manually of the Exp/ Ventus interface and comms
Setting for each time I restart Exp. I suspected and have now proved to my self that a few settings disappear on a restart.
This happened before this mornings races. Cross check found TTB and distance to line , plus damping had been turned off
In EXP. Set them back up for the races . Went us seemed to work ok. Shut down pc. Restarted just now and those item settings had gone again .note, this may be my pc .

NB. Have you ever see this issue before


Will check vs new install once I get charts running to see if the problem is in my laptop,
Cheers bob

Harry,

I have been unable to reproduce these problems so far.  

I have had issues with loosing the Ventus <--> EXP communication settings and parameters  in Expedition which naturally screws up the operation of Ventus Pro until restored.

 

So I guess I have to say sorry but whatever did go wrong it was not a fault in Ventus!

 

I will keep testing & trialing.
