Is it possible that it would show up as 4 com ports?

On a Windows machine, you should know what serial COM port you are using. If you are using a USB-Serial adapter, you could check the device manager to see what COM port is assigned.

I don't know how that works in Linux...

If you want to know if you are looking at the correct device, open a terminal program (in Windows, Hyperterminal), connect to that port at 19,200 8N1, CAPS lock on and send TEST, enter. You should get TEST back from the console. Send VER enter, and you'll get a firmware version, NVER returns a different version of the version. :)

Anyone have any luck using a serial-to-usb converter and using the DSI-01 on a mac?

What is the pinout for the serial connector, please?

I am trying to connect it to the ArgentData OT3m dual-port TNC for APRS rather than through a computer.

The Davis interface is recognized when connected directly to the OT3m (and others).

Thanks!

2 TX
3 RX

5 GND

7-8 jumpered

(Or 2 is RX, 3 is TX, I always have trouble with that. Try it each way.)

How would i hook this thing up?  I know the ethernet end would probably hook to router and serial end goes to computer but where does the black thing and other end of cable go?? Sorry if this is dumb question just weighing my options on which station i should get. If i get the vue i will purchase this data logger.

The black thing goes inside your Davis VantageVue - be careful not to alter the angle of the pins.

Did the usually-enclosed instructions get misplaced?  They are what I followed for installation.

The RJ45 "ethernet" connector plugs into the Serial adapter then that plugs into the Serial port of your computer - or if you don't have a Serial port then use a Serial-to-USB adapter.

HTH ...

Should the following work?

I tried to get Minicom (console/terminal in Linux) to see the Davis by doing the following:

1. Opened a Console/Terminal
2. "ls -l /dev/tty*"
3. "dmesg | grep -1 tty"
4. I noted that ttyS0 and ttyS1 were listed, when I tried the
    following with ttyS0 the terminal stopped responding but
    with ttyS1 it appeared to work OK - though no output.
5. Closed Xastir.
6. Shutdown the laptop, connected the serial cable, restarted.
7. Opened a Console/Terminal
8. "echo -ne '\CO\xFF\xCO' > /dev/ttyS1"
9. "Minicom -D /dev/ttyS1 -b 19200 -o"

Nothing.

A little help, please?

Start simple.  Power up the laptop with everything connected.  To verify which port to connect to, unplug the usb - serial adapter, plug it back in, and do "dmesg | tail".  Skip step 8.  Fire up minicom (see here) and just type in TEST a couple times.

I just tried different settings:

1. Opened a Console/Terminal
"echo -ne '\CO\xFF\xCO' > /dev/ttyS0" (I tried S4, S3, S2, S1, but only S0 responded properly)

2. "Minicom -D /dev/ttyS0 -b 19200 -o"

3. CTRL-A then z

4. In the pop-up Menu "E" to to turn on Echo

5. Then on blank screen (no command prompt) type TEST and received TEST echo.

6. VER = Oct 25, 2010

7. NVER = 2.14

8. STRMON = scrolling groups of data

9. STRMOFF = data display off

10. Next I will look at the scripts & see what ArgentData says ...

Thanks!

It looks like you aren't properly escaping this string.  Aren't you missing an 'x' before the first 'C0'?  i.e.

echo -ne '\xCO\xFF\xCO'

not

echo -ne '\CO\xFF\xCO'  ???

Also, could you educate me why this command is necessary in the first place?  I don't have a DSI-01, so perhaps this is some necessary incantation to wake the interface up?  The incorrect (I think) formatting of the first string suggests you aren't really sending what you think you are sending, so it may not be necessary at all.

Sorry, that was a fat-fingered typo.

"echo -ne '\xCO\xFF\xCO' ..." is what I used

And, yes, you are correct - it was unnecessary.

I did it before I discovered the CTRL-A z pop-up Menu where I could select "E" and set the echo on.

Now I am waiting on a reply from the ArgentData folks as to how I might get their OT3m to process the data stream - or if I have to have some PC-based (Linux-friendly) app pre-process it.

I already have Xastir dealing with the APRS details of mapping, etc. via a USB link to the OT3m, and have read that I may need a Perl script if I want WX data to be integrated into Xastir, or perhaps I might be able to backround-process the data and ship it out the Serial port to the Serial port on the OT3m.

The OT3m has a primary and a secondary port.

Thanks!

If it is Perl scripts you are looking for, these scripts might get you started.  Or you could tear into this code if Python is more your thing.

Well, the old laptop I have been using seems to be dying.....have another one, but no serial port.  Any one use this with a usb to Serial port adapter?
Thanks

I you, or anyone else, finds a Linux app that can read the weather data - and especially if you can get it out to an Argent Systems APRS device - I'd sure like to hear about it.

Right now the DSI-01 is laying on the table completely useless.

Thanks for the link!

I have inquired on the Puppy Linux dpup Exprimo discussion list if someone could port it over to that distro.

I will report back if that works out & I am able to make some progress ...

Thanks again!

You are welcome.  If it is Python, it should be no big deal to port to another distro.  I have Python code I run on 4 or 5 distros and in most cases no mods required. And remember - Google is your friend!!

The Puppy folks are usually very helpful so I will wait on them.

I've tried compiling and porting and always make a mess of things - it's wiser for me to be patient.

BTW: IMHO Google is not my friend, they are unfriendly to privacy.

I SEARCH with ixquick or startpage or one of the others - just as good and private!

YMMV ...  ;-)

Thanks!

Hi I just have a few questions about the DSI-01 Serial Interface...

-Is this all I need besides software to connect a vantage vue to my computer to websites like wunderground?
-Will this work with an Apple I-Mac computer?
-I heard rumors of new firmware update might cause problems with third party cables is everything still working fine with latest firmware?
-Is the only difference between this and the Davis logger that the davis stores info yours wont but both can get weather stations on to the internet though a computer?

To date, I've seen only one report that confirms incompatibility between the latest VP2 ('AA' in the Mfg Code) and Vue ('MB') consoles and third-party adapters of various sorts. But there's no reason at all to doubt that report, which would also tie in with what one might predict with the new console versions and their known incompatibility even with older Davis loggers. So the working assumption has to be that the latest consoles are simply not compatible with the third-party adapters.

Are you saying that the incompatibility is in the hardware or the firmware?

What date of manufacture/serial number/firmware version ID's the "latest", please?

Thanks!

There's no totally definitive information as yet. (There's no v3.00 F/W available for download for instance). But my guess is that it's hardware and F/W jointly.

Mfg Code is 'AA' and 'MB' as above (actually there may be some 'MA' Vues out there, but I've not seen any).F/W on all these is currently v3.00.

I have been using this interface for several months now. 

I am very pleased with how easy it was to set up.  It works quite well even after extending the serial cable to at least 30 ft. 

I've had only complaint that I finally took the time to rectify today.  This interface creates RF noise heard on several frequencies on my Ham Radio HF bands.  A raspy chirp is heard every time the data is updated across the interface coinciding with measurement changes visible on the Cumulus software.  I placed a capacitor across the black and green conductors to remedy it.  As far as I can tell now, all is well. 

Again, I really appreciate the effort that went into putting this interface together!
