CRS ColorCAL and Monitor Centre

[roblee_crs]

Hi PsychoPy team,

I, and at least one of our customers), are having difficulties using a ColorCAL II from Monitor Centre. I know this used to work, but I’m not sure how long ago. Details are below. I hope you can help!

Thanks!

What are you trying to achieve?:
Calibrate monitor with a CRS ColorCAL II from Monitor Centre

What did you try to make it work?:
Tried to select the ColorCAL II from the drop-down list of photometers.

Link to the most relevant existing thread you have found:

Konica photometers do not appear in dropdown after 2024.2.0 onward

In 2024.2.0 and later, the Konica photometers do not appear in the dropdown in Monitor Center. Below is what I see in versions prior to 2024.2.0. Any version after just says “Get more…”. Konica plugin installed via package manager. [IMG_4966]

What specifically went wrong when you tried that?:
Nothing is available in the list of Photometers in Montor Centre (only “Get more…”).

I have verified that I can use the ColorCAL from the terminal:
from psychopy_crs import colorcal
cc = colorcal.ColorCAL(port=‘COM3’)
cc.measure()
