You know, how people parse sentences is a fascinating subject.

Yep, sometimes the brain sees what it wants to see, not what is
actually there.

If I'm writing something really important, I'll try to sit on the
draft overnight and then read it again the next day before sending.

Reading it out loud is a great way to find mistakes.

What kind of sentence are you expecting the radio to send? Usually it
works the other way around with the radio receiving positional
sentences from the VHF.

DSC call info (for instance, the result of a position request)

To answer your question, you can read the data on your PC using the
hyperterminal utility under Programs Accessories Communications.
You will need a serial cable and working COM port.

Nice -- know where I can find the pin out for the serial cable?


Settings are usually 4800 baud, 8 data bits, no parity.

You could have a couple of different problems here.

That's what I figured...

Have you made the comm connection live on the GPS by selecting Comm port
1 or 2? Is there a similar selection on the radio?

well; no; I've connected by nema in/out

VHF NEMA OUT ---- GPS NEMA IN
VHF NEMA IN ---- GPS NEMA OUT
VHF GROUND - GPS GROUND

Check the wiring connections and make sure that you have NEMA out to out
and in to in. That's a common problem.

Wow -- then I totally fubar'd that installation -- since I read the manual; it
seems like "DATA OUT" form one device goes to "DATA IN" on teh other device....

I'll try it your way. Except the VHF radio is getting GPS data just fine, so
I'm betting that it'd fubar that up....

Out of curiosity, which model Standard is the radio? I ask because I
read somewhere what some Standard radios have a wiring misprint - I read
that on another forum.

VHF: Standard Horizon PS2000 talking
GPS: Garmin 498 Sounder

Thanks

Can you hook up a laptop and see what form the sentences take from
hardware "X" ?

I could; if I knew which way to plug in a wire to a com port....

"It don't work" isn't acceptable from tech support. "The two devices
will not communicate because......." leaves the door open to make it
happen.

That's why I'm frustrated & came here...

You need more information....

Like what? I'm out of ideas....

And you would exactly right.

D'Oh!!!

You have it right.

When I did mine, I had to open the comm 1 port on the GPS to engage the
NEMA data transfer. There should be a selection on your GPS menu tabs
to enable the comm port to engage dialog with the radio.

Sorry about that wiring mixup. :)

You are only interested in 2,3,5 on a 9 pin connector.
http://www.balances.com/scientech/im...2connector.gif
gives a picture. You can get an RS232 to USB cable for anywhere in the
range of $7 to a Belden at about $30. I got one at Fry's of the $7 variety
last year to run to my Garmin 162 for firmware and map uploads from the
laptop. IF no data coming in swap 2 & 3. A few years ago we got PCMCIA
RS232 comm cards for a project I worked on. the USB are cleaner and nicer
and cheaper. If you have an older PC they might still have a comm port.

Hmm. Nema only has 2 (data & common) common is, much of the time, just ground.

For instance, Garmin GPS has only 2 wires for NEMA (data IN and data OUT) --
you use ground for the common)

SO if I want to READ data, I'd just use 2 & (5 or 9)?

Thanks

Hmm. I'll have to look at it again.... I didn't see anything about com ports --
but I wasn't looking for it -- I"ll check it...

So you're theory is just that it needs a "bump" to get it going... I like it --
I hate computers, but I'm willing to try anything.

Sorry about that wiring mixup. :)
No worries...

I appreciate the advice.
