Parallel port address can not be read
Parallel port address can not be read
We just had the parallel port card recommended on this forum shipped over night from Jameco Electronics. After we install it, I/O test says "absent" by LPT1 LPT2 and LPT3. We got the address from device manager (57088) but when we type it into I/O Test, the new version suggested in this forum, it won't send bytes. We please need help ASAP!!! Our lab is shut down and have a major funded data collection that is stalled out because of this issue!
Are you using MediaLab or DirectRT?
we run both programs using direct rt to send ttl signals to physio coulbourne.
What are you using to test the output of the new parallel port card?
I/O test. that we downloaded from this forum.
I've been working with Paul on this issue, and here's what I know about the situation so far:
We installed a Rosewill RC-302 (http://www.rosewill.com/products/474/productDetail.htm) into our machine, and Windows XP SP2 detects it without any problems (see http://www.justinmyers.net/media/ttl/00.png). IOTest, though, doesn't see it at all (http://www.justinmyers.net/media/ttl/03.png). I tried a couple of different LPT port numbers (LPT1 and LPT3, given the device window at http://www.justinmyers.net/media/ttl/01.png), and none of them accept any new values from the IOTest application.
I also looked for the I/O addresses in Device Manager and found two ranges: DF00-DF07 and DE00-DE07 (http://www.justinmyers.net/media/ttl/02.png). I tried using every address in those ranges (with the new IOTest version from http://support.empirisoft.com/showthread.php?t=717 since I was having the same error as mugur65 described), but none of them worked. (As with the different LPT port options, they didn't accept the new values I was trying to send.)
As if that weren't all bizarre enough, the computer shipped with Vista Home Premium, and the card liked IOTest well enough after I installed it that time--but after we downgraded to XP (to get DirectRT to work), IOTest doesn't seem to like our port.
We then followed the advice of another thread on these forums (http://www.empirisoft.com/Support/showthread.php?t=644) and ordered the specific parallel card that thread recommended--and got the exact same result.
Thoughts?
If we could get you a copy of DRT for Vista, would that help?
I was able to parse the links above, by the way.
I may have a solution. John is making me a device that can send and read TTL signals to any given port address and should have it completed by the end of the week. I will then be able to test out some code that I think will solve the problem. I know you are under pressure to find a solution, but can you hold on until Friday or Monday? If so, I should be able to have something for you to try by then.
