Turns out there was a problem in the installer. We've updated 2.0.61004.5 with a fix.

Anyone who has run into this issue should uninstall Inquisit, download the current version and reinstall.

Please let me know if you see any more issues.

Hi Gerrit,

It's always possible there's a new bug. What is the exact error message you are seeing? Assuming it's "No device handle", there error indicates that for some reason, Inquisit is not able to connect to the specified port.

Try the following: open up Windows Device Manager and verify the location of the parallel port (e.g., LPT1, LPT2, etc). If you add a PCI parallel port to the machine, it will often default to a number other than 1. Make sure the port is enabled. Then make sure you are selecting the correct port number from the parallel port monitor.

Let me know the results.

Hi all,

for an experiment, I need to use a parallel port response box. Although everything works fine under the admin account, it does not run under a non-admin account and I receive the following error message:

Inquisit Error - Parallel port operation failed. - Line
Number: 235 - File:.\DirLptPort.cpp - Status Code: 9996 - Error Message: 'No
device handle'

Unfortunately, using the admin account is no solution due to the IT regulations
at our lab, that is, I need to find a solution for non-admin accounts. As has been proposed before, I have already uninstalled Inquisit, downloaded the latest Inquisit 2 version (i.e., 2.0.61004.7), and reinstalled it. This did not help. Again, I received the error message above.

Is there another option to overcome this problem?

Many thanks in advance!

Hi Sean,

Do you have any experience with using a PCI-DIO24 card (basically a PCI card) as a parallel port in Inquisit? My initial question to the forum was answered by someone who admitted he didn't have experience with that kind of interface.

Basically, we already have the newest trial version Inquisit sending a parallel-port signal successfully to our eye-tracker system. What we want to add on is another measurement modality, through a Biopac MP100 device, and we'd love for the parallel port signal to get sent there as well (unfortunately the eye-tracking and Biopac system can't be run on the same computer). One option we've considered is instead of using a PCI card (which a colleague had recommended but doesn't seem to be recognizable by Inquisit), to just divide the working Parallel Port with a splitter, so that the same port sends the same parallel port signal to two separate computers.

Any advice you have is much appreciated!

Looking over the specs for these cards, they apparently do *not* expose themselves to the system as parallel ports (LPT) and thus Inquisit currently is not able to use them. I'll repeat my previous statement that I think using a splitter cable on the existing native LPT interface is a strategy worth pursuing.

James,

I'm not familiar with this particular card, but Inquisit does work with other PCI-based parallel port cards. Here are some things to check:

1) Open up Windows Device Manager, and see if the card is listed under "Ports". If Windows doesn't recognize the cards as a parallel port, neither will Inquisit.

2) If it's listed in the Ports section, note the port number (e.g., LPT3) and be sure you are specifying that port number in your script

3) Right click the port in Device Manager, select Properties, and click the Resources tab. Note the IO range - this is the port's address.

4) Open the parallel port monitor in Inquisit, and select the port. Does Inquisit automatically select the address? If not, you'll need to specify it in the script.

Hope this helps,
Sean
