Andor IDus does not connect

[1234bnm]

Hey,

I am currently trying to set up a Spectrometer. for that I am using an older Andor Idus 490.

If I use the function Andor.get_cameras_number_SDK2() the feedback is 1 so I guess the implimentation of the dll worked

But if I try to connect the cam via cam = Andor.AndorSDK2Camera()

I get the following Error:

AndorSDK2LibError: function 'GetFastestRecommendedVSSpeed' raised error 20991(DRV_NOT_SUPPORTED)

is there a way I can solve this error?

best regards

Hello!

It looks like some of the standard functions are not supported by the camera, but the code does not account for it and raises an exception. Could you try and replace the file Lib\site-packages\pylablib\devices\Andor\AndorSDK2.py within your Python installation with the modified one and let me know if it fixes the issue?

Hello,

that worked like a charm; thank you verry much.

I am ontro the next error that has to do with the firmware I am gonna try to find a way to update it and let you know if I am getting any pictures.

Hello Alex,

I got the firmware updated (at least I thinks so) and now I am having a different Problem.

right now I am getting the Error :

AndorSDK2LibError: function 'SetMultiTrack' raised error 20068(DRV_P3INVALID)

when I want to initialize the Camera; do you have any idea how I can fix that.

Thanks fot the help!

Looks like a smilar problem: the camera does not support the "default" multi-track options set up during the camera connection. I would suggest opening the same AndorSDK2.py file (located at Lib\site-packages\pylablib\devices\Andor\AndorSDK2.py) and changing line 870 from

def setup_multi_track_mode(self, number=1, height=1, offset=1):

to

def setup_multi_track_mode(self, number=1, height=1, offset=0):

i.e., change the default offset value. In addition, if that works, could you also let me know what sensor size you get from the camera, i.e., what's the result of calling cam.get_detector_size()?

Hello Alex,

It does connect now and if I run cam.get_detector_size() the output is (512,1) which is what I was expecting.

Thank you verry much.

Hello,

I also have iDus camera (DU401A-BV) but in my case the initialization has troubles with the shutter.. I do not have an external shutter connected. Did this happen to you @1234bnm ?

You will find the output errors below,

Thank you very much,

Pedro.

Hello Pedro,

this error did not happen, while I was working with the camera.

[AlexShkarin]

Dear Pedro,

This error most likely means that the function GetShutterMinTimes is not defined in the Andor DLL. According to the documentation, it was introduced in version 2.93.300000.0, so most likely you just have an earlier version. To check it, you can run Andor Solis and go to Help -> About... in the top menu. It will be there under SDK Version 2 (e.g., 2.92.30008.0).

To fix the problem, you can replace line 531, which currently reads

return lib.GetShutterMinTimes()

with

return lib.GetShutterMinTimes() if lib.GetShutterMinTimes is not None else (0,0)

Let me know if this solve the problem, and if there are any other issues.

Sincerely,

Alexey.
