After a storm, and then some shadey guys ripping off our boats; I had to pick
upo some new electronics.

I picked up a garmin 498 sounder & Standard Horizon PS2000.

They both work fine, however, independantly.
When they try to talk (nema) is when I have a problem.

The VHF radio can read the position information from teh garmin. But the garmin
cannot read the information from the radio. (ie: DSC calls)

Garmin is telling me it "does work" and Standard Horizon is telling me that "it
does work" but it doesn't.

I have tried
DSC call
DSC position request
DSC distress

None of them make it to the gps, despite the radio picking it up. I have gone
over the nema wiring about 2 dozen times; so I fear it's a few hours away from
Garmin placing the blame on Standard Horizon, and then Standard Horizon placing
the blame on Garmin.

SO -- long way of getting to my question:
How can I test/see/read the nema sentence being sent from the radio to be sure
it's leaving the radio -- so I can send the gps in, and if it's not sending the
data, send the radio in?

Or, anyone have any bright ideas on what to try?

Thanks

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.

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.

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

You could have a couple of different problems here.

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?

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

Other than using a logic probe or oscilloscope, I'm not really sure how
you could view the signal real time.

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.

I'll be danged - I didn't think of that.

Learn something old every day. :)

Will it read display the sentence as transmitted?

Yup, hyperterm just displays as what arrives. You can save the data also.

Wait... I need my heart pills... there is something that Tom didn't already
know.... I ... neeed...my...nitro....

Hey - I told you, I've made an entire career of either forgetting stuff
or making mistakes.

Typo in above, should have read:

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

I didn't even notice that.

Yeah Mike, I know - hard to believe I'm not perfect.

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.
