If your experiment freezes, OpenSesame has chosen the wrong serial port and you must enter the device name manually. By listing allowables and omitting 5 as allowable, it should ignore the 5 response. None timeout — A timeout value in milliseconds or None for no timeout. And, lastly, are TTL pulses “5” signals sent out during the disdaq period??? If you do not specify a device, the plug-in will try to autodetect the SR Box port. It is connected to serial port COM1, which is probably the default setting. The SR Box must be in sending mode when you call [srbox.

I just wasn’t certain if the 4-button box on the 3T was already set to map out a keyboard numerical response i.
If your experiment freezes, OpenSesame has chosen the wrong serial port and you must enter the device name manually. By listing allowables and omitting 5 as allowable, it should ignore the 5 response. Small 4-button box on 3T. Aug 07 2: Cheers, Jeff Reply author: You can set your input parameters to expect button 5 as a trigger start signal, and then only pay attention eevice buttons for user responses.
I appreciate your time and input. This is done automatically by the srbox plugin when the experiment finishes. There has devcie some ePrime confusion this past week with the installation of version 2. Aug 07 4: I’m not an ePrime expert but I suspect you do need to specify that you are using the SRBox device in the software. I’d say the advantage of having the scanner trigger is one of precision — an automatic trigger is going to be more exact timing-wise than a person hitting both buttons at once by hand.
The NeuroScan box is still connected. So you want to Prep the scanner, then set your paradigm to start waiting AND dsvice sure your paradigm knows to include the Disdaq period, if any, before actually srbbox the task. I believe that is the standard ePrime arrangement.
And, lastly, are TTL pulses “5” signals sent out during the disdaq period??? There are also SR Box compatible devices by other manufacturers, which may differ in the number of buttons and lights and often use a USB connection, which emulates a serial port. You need to call [srbox. There is an inventory of all hardware connected at each scanner at: None timeout — A timeout value in milliseconds or None for no timeout.
They are also sent during prescans. Jul 24 4: If you do not specify a device, the plug-in will try to autodetect the SR Box port. However, on some systems this freezes the experiment, so it is better to explicitly specify a device.
What would be the advantage of doing this other than avoiding having the tech to simultaneously press keys to start the scanner and task? Turns on sending mode, so that the SR Box starts to send output. Small 4-button box on 3T Printed from: Are the four keys for this box already mapped to the task computer keyboard?
I now know what the problem is, but not how to implement the change. Assuming you’re using the eStudio GUI to make the changes, open the properties for the object linked to response collection. The SR Box must be in sending mode when you call [srbox. Let us know if you can’t.
Sends a single character to the SR Box. Srboxx srbox object is created automatically by the srbox plug-in, and you do not generally need to call the constructor yourself. Small 4-button box on 3T Posted on: The ePrime SRbox is not set up as a keyboard device on our scanners.
