In praise of SB\'ers, and Tome in particular

It has often amazed me how much experience and more importantly, knowledge, there is among the particpants of this forum- well all of them really. Any subject that is broached, and query for help, even the pictures of unusual places posted on the forum always elicit a knowing response.
Now I had been trying to find a professional who could connect my Navman 5600 to our new Icom 601. I have had two or three shake their heads sagely, while tutting and frowning, and then telling me that these two pieces of equipment must actually talk different languages, despite the instruction books telling me different., because they couldn't get a GPS position on the DSC radio.
Fanfare of trumpets!!!
Then along comes Tome, who not only understands NMEA, but talks it himself. In a few minutes he had the problem solved, wrong connections on the radio input plug, and all was working fine.

A bit cheeky I admit, but it was amazing to see on Tome's computer the NMEA sentences all coming down the connection from the GPS, and then watching him read the same instruction book all the others hadn't understood, and setting all to rights.
So, I would like to publicly thank Tome, who I am convinced is a genius, and all the other Forumites who have helped me and my boat over the last two years or so.

Don't know what software Tome uses for looking at the NMEA data flow but NMEA Tool from http://www.nmeatool.de/ works well for me. You can save a "log" of data at any time for any duration and examine it at liesure. The software also gives you the format for all the NMEA sentences, which is very useful. You just need to feed the NMEA in on pins 2 & 5 of a PC serial port, tell NMEA Tool which port it is and your in business. I used it to confirm the heading input to my radar dispaly was being received 10 times a second rather than just believing manufacturers' specs.

Re: In praise of SB\'ers, and Tome in particular

Tome is a great fella but I've got pictures yer know..

Turned up on Asterie, scope in hand (had to get the manual out 'cause his memory 'aint too good) muttered and mumbled about the frequency of the fridge interference and mumbled about filters and things.

Anyway at the weekend he drops a filter on the table which worked as soon as i wired it in.

There is a waitress in the Langstone Hotel Northney who keeps asking after him.

And his PM mailbox is full..

Becky, you're very kind and most flattering. On the way back to the office my car broke down and I was pushed to the side of the road by 2 white van men impatient with me blocking the green light, which just goes to show that speaking NMEA isn't everything.

Lovely to meet you. Cornish Maid is a solid and lovely boat. I look forward to hearing updates on your passage South.

Thanks so much for the wine. Have resisted the temptation to open it as my dearest returns shortly from her teaching and we'll enjoy it together.

Fair winds
Tom

Looking at NMEA data is easy and you don't need anything special.

Connect NMEA A ( or NMEA +) to pin 2 of a 9 way D type female connector
Connect NMEA B (or NMEA - or else ground) to pin 5 of the same connector.

Plug this connector into your PC serial port

On your PC go Start, All Programs, Accessories, Communications, Hyperterminal

Set it to connect using COM1 (or whatever) and set the protocol to 4800 baud, 8 bits, 1 stop bit, no parity.

This is what Becky was looking at.

Re: In praise of SB\'ers, and Tome in particular

Yes, I used Hyperterminal in the first instance but came across NMEA Tool when searching for a data rate measuring element. Although the latter doesn't give a timing element, I found it easy to create a log over a manually measured time and then examine the log for number of sentance occurances after its creation.

For "system" NMEA monitoring, MaxSea on my "installed" boat PC provides an immediate on screen output from the Utilities menu as well as a real time translation of all sentences the software can utilise. I expect there are many other applications which can do this too.

Re: In praise of SB\'ers, and Tome in particular

WHen I tried to use Hyperterminal recently (to test the data from GPS into laptop), it was trying to create a dial up connection, and didn't offer me anything else. I was running out of time, so gave up and haven't investigated further yet.

Is this normal, and is it easy to resolve?

Re: In praise of SB\'ers, and Tome in particular

Set up a new connection in Hyperterminal, call it NMEA or suchlike
Make sure that you are connecting direct to a COM port as below (NOT through a modem)

Set baud rate etc as follows
