ok,, i built the ir probe, in fact,, i built 2 of em,, just in case i burnt the first one with my soldering gun. i cant get this thing to work.
im using win 98 se and digitrace. im not getting any errors. when i try to sample, im following the directions for the settings;

Set Trigger Channel to 8.
Set Pre trigger delay to 0.
Set Samplesize to 32768.
Set Sample period to 0.
Set Input Port (Hex) to 378, 278, or 3BC as appropriate.
Set Background and Foreground Color to your preference.
there is no conflict with 0378 on my lpt port.
it doesnt seem to be getting any signal at all .
should i be going to a different forum with this?
thanks,
mike

Have you tried CaptureIR?

If it works, I think you find it much more useful than digitrace.

I don't think anyone has tried it yet on win 98. I hope it works. If it doesn't, I can probably fix it.

ok,, i tried captureir. i downloaded the latest version of java rte. i got an warning message from java saying that my version of xp pro was not supported. i installed it anyways.
i loaded decodeir, and put port talk in the registry and the sys file in /system32/drivers directory. when i start captureir, everything appears fine and i get no errors. when i click "sample" the program closes.
the computer im working on has a dual boot. when i was working with digitrace, i was working in win 98se. ive been using xp pro with captureir. both versions of windows are clean installs (its an old doorstop that i recently put back into service with an amd 2-300 cpu).
im kinda running out of ideas here. if you have any tests i can run to verify that either of my ir probes are good, or anything else for that matter. i would appreciate it.
thanks,
mike

it appears that java is generating the message i found in my captureir directory. the top part of this message reads as follows;

An unexpected error has been detected by HotSpot Virtual Machine:
#
# EXCEPTION_PRIV_INSTRUCTION (0xc0000096) at pc=0x0af220fa, pid=1144, tid=1504

Current thread (0x0aba5898): JavaThread "PPortReaderThread" [_thread_in_native, id=1504]

siginfo: ExceptionCode=0xc0000096

i can include the entire message but its rather lengthy.
i think i may need a day off from this project, lol. and you are correct,,, it says "start capture". the version of captureir is prototype12 build 1 and signal decoder 2.33. ill have to work on that batch file, and ill let you know.
i appreciate your time,, many thanks
mike

i created a batch file using the edit command in msdos, i cut and pasted your file and replaced the path to match java on my machine. the file executed successfully with no errors. its still doing the same thing.
have you ever used netmeeting? if you were willing,, i would setup netmeeting on my machine and let you log in with desktop controls and you could look at it first hand. although,, that could turn into a real Rube Goldberg,. i think netmetting uses alot of recources, and as i said, that computer was a doorstop before i brought it back to life..
as another possible option,, i could send the whole shootin match to you,(remote, and probes) and ask you to create a code for me that would work with slingbox (you could also tell me if i got the polarity right on my probes). i would gladly pay you for your time.
i dont mind learning new things, but i dont have a ton of time to devote to my extra-curricular projects. i am a carpenter by trade, and im feeling a tad helpless here, lol.
again, many thanks for your time,
mike

I meant that the batch file ran without any errors, captureir still does not work. the batch file doesnt hang on the screen long enough to see what its doing.
as far as the ir probe,, i wired it the way it was in the document. with the ir sensor facing you and the wires pointing downward, the right wire goes to pin 1, the center wire to pin 9 and the left wire to pin 25 (pin 25 being the lower left pin while viewing the back of the connector.,. i suppose i could try reversing the two outer wires. i did see mention of some lpt port not having enough voltage (3.5). i have not checked the voltage at pin 9.

this is a cut and paste from the "how to build an ir probe" document;

The only source I know of for this IC is Mouser Electronics (www.mouser.com). The Stock No. is 512-QSE158, and the current price is 70¢. There’s no minimum order but you will have to pay for UPS shipping, so you may as well order the DB25M connector (Stock No. 156-1225, 99¢) and a DB25 hood (Stock No. 156-2025, 65¢).

these are the parts i bought from mouser (except the DB25 hood is on backorder). i bought enough parts to build 2 probes (in case i screwed one up).

no,, i dont know how to write a "pause" in that batch file. this is the batch file i have for captureir,,, "D:\Program Files\Java\jre1.5.0_11\bin\java -jar CaptureIR.jar"
i will try removing everything i have and starting from scratch.. and see where that gets me.[/quote]
