Andor Timeout Error

[lrennaIOS]

Hello,

I have an Oriel DB401-UV I am able to connect to the camera and get different status information. I can also open and close the shutter, etc. However, it times out whenever I try to get an image (with snap or grab).

cam = Andor.AndorSDK2Camera() # connect to Andor SDK2 camera (e.g., iXon) print(cam.get_full_info()) cam.set_exposure(0.1) # set exposure to 100ms frame = cam.snap() # grab a single frame cam.close() # close the connection

There doesn't seem to be any obvious reason for why it would time out. Does it work with the native software (i.e., Andor Solis)?

Also, to further debug the issue, could you try the following code:

import time

cam = Andor.AndorSDK2Camera()
print(cam.get_full_info())
time.sleep(10.)
print(cam.get_full_info())

This will show if any properties changed during the acquisition,

[lrennaIOS]

I have to do something like this:

cam = Andor.AndorSDK2Camera(idx=1, temperature = -30, fan_mode = "on")
print(cam.get_full_info())
time.sleep(10.)
print(cam.get_full_info()) 

or i get:

And i get the same timeout error as before.

Unfortunately, I do not have access to Andor software.

[AlexShkarin]

OK, I see. Can you now try

import time

cam = Andor.AndorSDK2Camera(idx=1,temperature = -30,fan_mode = "on")
print(cam.get_full_info())
cam.start_acquisition()
print(cam.get_full_info())
time.sleep(10.)
print(cam.get_full_info())

to see if any settings change when the acquisition is started?
