ASI220mm mini PHD2 recognize

Dr_E

I have 120mini, 220mini, 174mini and 432mm
PHD2 DOES recognize the 120 and 174 when connected to 2400MC and 533MC
PHD2 DOES NOT recognize 220mini with same cabling whether plugged into camera, hub or directly into computer.

Please help. I would have gotten another 174 instead and may request refund.

More details:
Windows 10 Pro on mount PC
OS Does see camera (220mm and either 2400MC or 533MC). Both listed in Device Manager. PHD2 does not recognize 220mm. Other guide cameras recognized by PHD2.

Dr_E It is because the ASIcamera SDK file in the PHD2 installation folder is not the newest version.
You can download the SDK file here, and replace the same name file in the PHD2 folder.

I downloaded your version of ASICamera2.dll and copied it into the PHD2 diretory as you suggested, but after that PHD2 would not start and run into error as shown in the picture:

DedeM31 what is the SDK version you duplicate to the PHD installation folder? x86 or X64.
As PHD2 is a x86 version program, needs to duplicate x86 version SDK file.

thanks for the reply. i did used the wrong one, the x86 works for me.

thanks and regards

Tech@ZWO Hi,
I did what you told DEdeM31 to do but still not connecting to PHD2 with the ASI220mm. Is there an actual reason it is not connecting with windows 11, or is it a PHD2 problem? I've downloaded every driver that's been mentioned with no luck.
Thanks

Two ways to connect ASI220MINI to PHD2.
1 Via ASI driver.
Because PHD2 has not update to the latest version ASI SDK file Need to replace the x86 version SDK file in the installation folder of PHD2 manually, then choose 'ZWO ASI driver' to connect.

2 Via ASCOM driver
Just need to install the ASCOM platform and the newest ASCOM driver. then choose 'ASI camera(ASCOM)' to connect.

Here is the download link of ASCOM driver. https://www.zwoastro.com/downloads
