Hi,
I have troubles with sending signal to EEG (BIOSEMI program).

CODE:
<port erasereeg>
/ port = LPT1
/ subport = data
/ items = ("00000000")
Error: Failed to load parallel port driver

CODE:
<port feedbackeeg>
/ port = LPT1
/ subport = data
/ items = ("00001111")
error:Parellel port 1 not found on this machine.

How can ı fix it?

You probably need to install the inpoutx64.sys driver, which isn't packaged with the application anymore, because a number of anti-virus applications flag the driver as vulnerable.

Probably the easiest way to do that is to install an older Inquisit 6 build ( e.g. https://inquisit.millisecond.com/6/6_5/win/Inquisit_652.exe ), which still has the driver included. Reinstall Inquisit 7 after, so it can grab the IQX, etc. file extensions again.

For background: inpoutx64.sys is an (open source) Windows kernel driver used for TTL (Transistor-transistor logic) communication via a system's parallel (LPT) port. Unfortunately, the development of inpoutx64 has ceased and no drop-in replacement is readily available, given the legacy status of the parallel port as a communications interface.

Note that as of versionn 7.0.3, Inquisit 7 supports Lab Streaming Layer ( https://labstreaminglayer.org/ ) as an alternative interfacing option, so if your equipment supports LSL, that would be the way to go.

Thanks for answering, I installed the inpoutx64.sys driver as you mentioned,but I still have problems about the port.

Error:  Parallel port 1 not found on this machine.
code:
<port feedbackeeg>
/ port = LPT1
/ subport = data
/ items = ("00001111")

<port erasereeg>
/ port = LPT1
/ subport = data
/ items = ("00000000")

 What can I do for next step?
Thanks for your help,again.

The computer has a com6 port that works in an ERP task, lpt is defined in the inquisit script. How can I define the port as com6 for the task to run?
