Trigger problem

[cansu.ozceri]

Hi, I am having problems sending triggers to biosemi active two system. ı use inquisit script. here is my code
<shape incentivecue>
/ shape = rectangle
/ size = (values.stimsize * 0.75, values.stimsize)
/ position = (50%, 50%)
/ color = red
</shape>
<port incentivecueeeg>
/ port = COM6
/ subport = data
/ items = ("00000001")
</port>
<shape nonincentivecue>
/ shape = rectangle
/ size = (values.stimsize * 0.75, values.stimsize)
/ position = (50%, 50%)
/ color = red
</shape>
<port nonincentivecueeeg>
/ port = COM6
/ subport = data
/ items = ("00000011")
</port>
<shape eraser>

/ size = (values.stimsize * 2 * 0.75, values.stimsize * 2)
/ position = (50%, 50%)
/ color = black
</shape>

ıs there a problem with port?

[cansu.ozceri]

When the port is defined as lpt1, it sends a trigger to another device. Is there LPT parelell Port in biosemiactive2?

Hi, I am having problems sending triggers to biosemi active two system.
I use inquisit(millisecond) task script.

I have no problem sending triggers on the same device with the com6 serial port in an experiment written in python.
This experiment written in inquisit sends triggers when the port is defined as lpt1 on another eeg device.
However, I see that when I define the port as com6 in my experiment script written in inquisit, it does not send triggers. What should I do?
Thanks for the help.

Hi,

I have no problem sending triggers on the same device with the com6 serial port in an experiment written in python.

This means that the hardware is working properly, the use of a com port means that you are using the Biosemi USB trigger interface (or compatible third party equivalent)
The Biosemi USB trigger interface communicates with the pc using a serial port, if you want to send triggers with inquisit then you will have to either change your software to write the triggers to a serial port in stead of a LTP port or use a Biosemi LTP/parallel port trigger cable (or compatible third party equivalent)
