Help, Nav software that puts my GPS to sleep.

Hello,
My name is Ryan and I'm up in Maine trying to get my Cap'n Software v-5.2.0 to work with my Garmin 182C. I have another program working just fine (SeaClear, but is isn't a nice as The Capt'n) and even when I fire up Cap'n, she sees the GPS at first.

The problem that I have is that after about 1 min of good GPS lock, I get an error saying "Your GPS appears to have gone to sleep" Then I have nothing. Any thoughts? I don't really want to spend $$ on a new, updated copy if I can get away with it. I've looked inside the GPS and there is no adjusting the settings. It's locked at NMEA in/out and 4800 baud.

Is there anywhere inside the Capt'n program (or in the file structure) I can tweak a setting?

Please help if you have thoughts. (Other than: "Go buy new software!")

Ryan

If you have more than one comm port on your computer, you could try it on a different comm port to see if the port is the issue. It might be an IRQ conflict. I kind of doubt that—especially since SeaClear seemed to not have a problem, but it is worth a shot. It could also be that you have some other software running in the background, like Palm Desktop or something similar that is grabbing the serial port from the GPS chart program.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

thanks for the thoughts. I'll make a DB-25 to test with.

I've been playing with this problem for a long time. Across several platforms, NT, XP and now VISTA. Also several different installs on different Laptops. So far, the problem has followed the software.

My laptop is set up as dual boot so I try everything on Vista first, if it acts squirrelly then i pop over to XP and confirm it is a Vista problem.. So far so good. Problem is still there on both OS's.

Thanks for the thoughts.

I'm hoping some one else out there knows of a setting in the program or a registry hack I can do.

Did a quick search and didn't find anything at first glance, but you may spend more time delving into their support docs. Could be a compatibility issue with this version...

Assuming that you have a USB GPS.... I'm willing to bet that this is a USB Driver issue. I had the same problem with my iPod Shuffle. When I'd first plug it in it would work OK for about 2 min. Then it would disappear. I downloded a patch from Microsoft a couple of months ago that fixed the issue. You may want to start at the Apple support website to see if you can triangulate on the problem that way.

Hope this helps!

This is interesting in that the GPS stays up while using Seaclear but not of the Cap'n. An interestign thing to try would be a serial port listener application which will pump all the data form your port to a screen. If the GPS is still transmitting data when the Capn says you are sleeping you can lean towards the application as the problem. If indeed there is no data coming through the port then you can look into an OS/driver problem or a possible hardware problem with the garmin.

Give this a shot, Tucows Downloads - Serial Port Monitor 3.31 Shareware Software

Good luck.

Thanks, but I've already ruled out the OS and the PORT issues. The port I'm using is a serial, (Com1) and I know the GPS is constantly throwing out data because SeaClear sees it for hours at a time. I even looked at the data stream using SeaClear's Port Listner thing. I know it's not an Operating System problem because I get the same results using NT, XP and Vista. SeaClear works just fine in vista. I did have to emulate NT to get Captn to install but that is where the program is intended to run (for my version 5.2.0)

I'm looking for some one who knows the inside of Captn and may know of a setting I failed to see or a Registry Hack that stops the program from thinking the GPS has fallen Asleep.

Thanks.

I'd even be happy with a "I tried it and it does not work with a newer Garmin 182C"

Check if your Garmin as an "auto shut off" or a function that help saving the batteries .
Check the software if you can adjust the number of read per second.

I doubt it is the Garmin 182c, as it works just fine with SeaClear. It is pretty definitely a bug in the version of Capn that you're using. It might be worthwhile to check their site and see if you can get the last bug patch for the version you have.

Open the "HyperTerminal" from your Windows when your GPS sleep again while using "Capn". If you saw NMEA strings displyed on the screen, then forget about "Capn". If not, ..... check the USB driver.
