EFW Power Surge Cross posted from Cameras

seldom

My ASI1600MMC worked for a while today but when I reconnected and none of my Windows 10 computers recognize the camera. My warranty for the camera and filter wheel has about 9 months to run.

Further examination found that the camera worked when the filter wheel was disconnected, but if I connected the EFW filter wheel cable to the camera the camera disconnected. When I connected the EFW filter wheel to the laptop directly, the laptop gave me a USB Power Surge message. So I assume the power surge was shutting down the camera. Is there a way I can reset the filter wheel, or must I return it to ZWO?

Does this EFW can be recognized by computer as a HID device?

This EFW only appears as an Power Surge warning. Chad said that indicated a mechanical problem and it is being returned to ZWO.

OK, please return it for repair.

I have the same error. My engineer friends say probably another fried PCB. Given the trouble I had with returning my 6200 2.5 years after purchase. I decided to just purchase a replacement.

My EFW has developed the same problem. It is out of warranty now but I am reluctant to buy a new one if there is an known issue with it. What is the official response from ZWO regarding the issue? What causes it? Is there a fix? It seems like something is shorting to me.

AlanM It's a problem of the parts on the pcb, and need to ship back for repair.
