Problem with TTL, Parallel Port, I/O test (case 1098)

Hi,

I'm working with Patrik Juslin's Music and Emotion research team. We are currently trying to send a trigger to the BIOPAC system from MediaLab when a piece of music starts playing. We send the trigger to BIOPAC MP150 via UIM100C. To try the I/O test, we followed the instructions of Media Lab. When everything was connected and we opened the IO test page, "LPT1:error", "LPT2:error", and "LPT3:error" showed. We also tried entering "888", but it didn't work. We are using MediaLab 2010 on Windows 7, 64 bit version. We tried to use this parameter (d3, <128:888:3000), but obtained no response from the computer running BIOPAC. We are using VScom LPT Class (LPT3) card on both computers. The drivers are updated. The hardware information tells us that LPT3 is being used, but we still get the "LTP3: error" message. In BIOPAC, we followed the instructions on how to connect the Printer Port setup ribbon cable, but the program still receives no trigger. It would appear that there is no signal sent out from MediaLab through the port. We would be very grateful if you could help us out with this matter and, if possible, send us a step-by-step guide to solve the problem.

Best regards,
Goncalo

Hi! If you poke deeply in the PC's Device Manager control panel, you'll find the parallel port you're using. Click on it, then look through the tabs on the displayed window. What address is the port assigned to?

May also simply be a v2010 compatibility issue with Windows 7. A number of TTL issues were resolved for Windows 7 in version 2012. Any chance you could try that on one of your machines to see if that resolves it?

Hi,
Thank you so much for the replies.

I have this information in Device Manager:
VSCom PCI011H-EP1 controller
Ports for this card: Parallel 1 -->LTP3

Resources: I/O-Interval E030-E037
I/O-Interval E020-E023
I/0-Interval E000-E01F
Memory Interval 00000000FE500000-00000000FE500FFF

I already downloaded MediaLab version 2012. Just waiting for the code.
Please let me know if this is the information you required.

Thank you so much,
Goncalo

Trial code sent. Do update us on your progress...

Hi,

Since I installed version 2012, I/O test does not even start when I click on it. I'm trying to send a trigger to BIOPAC, when a piece of music starts playing. Could you tell me if this parameter example is correct? (d3, <128:888:3000). If it?s correct what kind of reaction should I get in the other computer screen?

Thank you so much,
Goncalo

Which version of v2012? There's a full version number in the 'help' menu...

Version 2012.4.118

It's realy strange. After installing this version, IOtest.exe does not run. And before installing v2012 IOtest was able to run. Even tried using compatibility mode and still nothing.

Hi,

I/O test still does not run. We uninstalled v2012 and recovered the windows 7 system to a previous date where I/O test v2010 worked. I/O test worked great again with this version.

Today we bought a new license to v2012 and uninstalled v2010 from the system again. The same problem occurs I/O test simply doesnt run. Is this a known issue?

Thank you so much,
Goncalo
