SharpCap Forums

Hi,

In 2025-12-31 night using 4.1.14089 version all was OK but in 2026-01-01 when I updated with 4.1.14091, the connect is failed with my iOptron CEM70G

I exit SharpCap, and and I tried to connect with Ioptron commander app, ??? failed too ???

What do you think happen dur the install procces ?

Best regards

Have beautiful 2026 year

Hi Marc,

this sounds very much like the failure to connect is unrelated to the change in SharpCap. You've done the right thing by testing direct from iOptron Commander, and the fact that you cannot connect there basically proves that the SharpCap change has not caused whatever is going on (anyway, the change between those two versions is purely related to the crash when hovering over the new menu item).

I think the things to check for you are

* physical connections to the iOptrion mount - check all cables are still firmly plugged in
* Power to the mount - check it has power and switches on
* Check Windows Device manager - look in the Ports (COM and LPT) section. There should be a COM port there for the mount - pull the USB plug to the mount and one should vanish, put the plug back in and it should reappear.
* Check the settings in iOptron commander for the COM port - make sure it matches the one that is vanishing and re-appearing when you pull/replug the USB cable

Hopefully something in that list will point you in the right direction.

cheers,

Robin

OK thanks Robin, I will see that on the nest clear night
