Port deteceted but no trigger is sent

Mojtaba

Hi everyone,

I am trying to send triggers (1,2,...) through a pserial port from a PC computer (windows 10) to an fNIRS device (NIRScout). It seems that OpenSesame recognizes the port (COM1) and run pretty well without showing any error. But on the recording software, I see no trigger. I wonder whether can help me to find the solution.

Thanks ahead,

Mojtaba

I followed the steps that Jerik explain as below:

Managed to get this working without using test mode by downloading the Binaries only from http://www.highrez.co.uk/downloads/inpout32

Unpacking the Win32 folder.

Running  InstallDriver.exe as Admin

Copy the file inpout32.dll from Win32 to c:\Windows\SysWOW64\ and rename it to dlportio.dll

The experiement runs but I receive no trigger on the recording computer. I appreciate any tips.

Best,

Mojtaba

Hi,

We're having exactly the same problem. Port is initialized, trigger is logged, but no trigger on the recording computer (using g-Recorder by gTec for EEG).

We urgently need to resolve this. Any suggestions or help would be appreciated.

Best,

Hi Michelle,

Hard to say what is wrong without having access to your hardware. I would recommend trying to interact directly with the port via the pserial package (in a python shell or something like that). Then you will have more control over what is happening and might even see an actual error message that you can work with.
