Problems with SRBox Generating Response

[Julia Dipassio]

Hi everyone,

I'm running into a problem with the SRBox 200A. It's connected via Serial port and is ready to go, however when I run my experiment it's not receiving feedback. The goal is to have participants rate their preferences for images on a scale of 1-5.

I've been reading about task events and watching some videos (ie, how it operates as a "cause and effect" essentially), however I've had problems with details regarding the parameters for serial ports.

Some troubleshooting I've tried:

- made sure it appears in the experiment object properties (collection is presses only)

- for the slide properties, the allowable response options are {ANY} (the responses are 1 through 5, however I've read that's already configured within the device).

- Time limit is set as "until feedback"

- Task events are slide.onset time and Slide.SRBOX(1).Press.  

- For  Slide.SRBOX(1).Press.--> Task Name: Serial --> Action: WriteByte. The parameters are Custom, data type Integer. 

- For SlideOnsetTime, its the same parameters as above (serial as task). 

Any help would be appreciated. Thanks so much.

Did you start by running the demo program that comes with the SRBox and make sure that that works? I would always start by doing some sort of simple "Hello world" type demo before trying to incorporate something new into a larger program. "Better to start from success than from failure."

Hi David,

As it turns out, the problem actually resided within the Port settings - in the experiment object properties, I had to change the properties of device  "Serial" so that it was connected to COM Port 1, and SR BOX to be connected to Port 2. I appreciate your help, thanks so much!
