The "offical" LXNAV V7 thread

Ted,
I may be misunderstanding your question, but I do not think that you can upload a task "to" the V7. You can upload a task to your GPS Logger (e.g. Nano) by going "through" the V7 (See setup example in section 8.4.2 of the manual). The relevant section on how to perform the upload is 5.1.2. In the "Direct Link" mode, the Oudie communicates directly to the Logger.

Okay, things are starting to make a little more sense. On page 16 (section 5.1.2)there is a turnpoint name ("Line 11") above the course direction indicator. When I saw that, I assumed I there was some task storage and processing in the V7. If the task is not in the V7, where does this turnpoint name come from? (From the Oudie, or from the logger?)

The Oudie will have to send the active TP coordinates in an RMB sentence
back to the V7.

The Oudie will have to send the active TP coordinates in an RMB sentence
back to the V7.

It must also be getting at least the WPL sentence and possibly is also
getting ROO sentences. I say this because the RMB sentence conveys the TP
coordinates but doesn't contain its name. Both ROO and WPL include the TP
name. WPL contains the name and coordinates of a TP: by comparing
coordinates between RMB and WPL the receiver can work out the RMB's
target TP name. ROO defines the task (in our terminology). All it
contains is a list of TP names in task declaration sequence.

The reception frequency differs depending on the sentence type. An RMC+RMB
pair are received every second with a third sentence appended. This
sentence is either an ROO or a WPL. The ROO and associated WPLs are sent
in a repeating sequence, one each second, so if you have 'n' turnpoints
in the active task, the sequence takes n+1 seconds to be sent.

I researched this some time ago when I wanted to understand why my SDI C4
wouldn't calculate wind unless the GPS it was attached to, a Garmin GPS
II+ at that stage, had at least one active waypoint. I ended up with the
Garmin plugged onto a PC and displaying each sentence as it arrived so I
could work out what was going on.

You need to ensure the baud speed for your logger is the same as the baud speed for the PDA (as the V7 gives the PDA direct access to the logger when declaring a task). This should fix the problem

Has anyone had luck uploading tasks from Oudie to V7? This topic isn't discussed in the user guide, and I'm not having any luck repeating the settings in the youtube video on the subject (device = "LXNAV - Nano", interface = "COM4:", speed = "4800bps".



In the video, there is very quick connection and transfer.



When I try it (using the latest V7 firmware and Oudie version), I get "Connecting" on the Oudie, and the communication icon on the V7, but nothing else.



thanks

I load tasks from an oudie through a V7 to a red box flarm/logger. The red
box has a basic flarm display and communicates with it at max 19200 baud
(this can also be set to a lower figure and determines the speed of the
whole link). Consequently I have to set the V7 GPS and V7 PNA links to
19200 and it works fine.
