I have the ASI2600 MC Pro and ASI183 MC Pro cameras on two different setups. Both are interfaced (power and connection) through ASIAIR+. I get intermittent disconnects of either my ZWO EAF and/or ZWOASI120mini camera when connected to either camera's USB ports. This does not seem to happen when connected directly to the ASIAIR+. Is this a power issue or is there a problem with the USB ports on both cameras? I tried swapping cables around without much success. Many thanks for your comments. |

I had a similar issue. When I tried connecting my Lodestar guide camera into my ASI2600MC it froze. Since then I have connected a ZWO filter wheel and it works fine. Just a guess: only ZWO accessories will work.

I think if you are going to connect a USB device to the camera, the cable from the camera to the Aisair should be USB 3.0, like the duo uses: https://www.zwoastro.com/product/asi2600mc-duo/ |

It's not the data cable to the ASIAIR+, only the peripheral components like the guidescope and EAF. I do use a USB-3 data cable for image capture. Thanks.

Hi, have you check the settings of the 12v ports on the Asiair? They can be set at different power.

I have the asiair+ and it has not aged well. the sd card fails regularly and wifi bad. I actually don't trust the device I use it to power a dew strip now. that being said I would say that the usb ports on the camera are likely faulty as your other devices are working as expected connected directly to the asiair. (my asiair mini works flawlessly, but going forward will likely not replace the air device and go an alternative route.)

I recommend dropping back to USB 2 cables and see if that eliminates the problem. If it does then you can likely just leave it or do more troubleshooting. USB3 is notorious for problems. If you don't want to do that and you are using USB3, make sure that the bandwidth setting is set as low as possible. For some reason the ZWO drivers use a higher than necessary setting.

I don't own an ASI air. But from an outsiders perspective, the main power supply maybe is not able to deliver enough current or maybe the cable to the ASI air is too thin? I had those issues on other equipment as well. It seems, that some devices are deactivated by the USBs power controller to prevent problems. I can't say, if this is the case, but maybe you should at least have a look.

about the guide cam my own guide cam, the asi174mm mini, has a loose USB-C port it disconnects if I don't use some tape to make the USB-C connecter be at a slight angle inside the guide camera USB-C port I have this problem probably because I jerked the cable out of the port, and/or wiggled it too much before |

I, personally, haven't seen this problem with rather similar gear as yours, Michael. I'd really check out your power supply to the camera. I have my camera power connected directly to my power source that is over-spec'd to ensure that the camera will work with cooling and connected EAF & guide camera. For me, this works like a charm (the same power source runs my ASiair+, as well). You might like to try a good old-fashioned SLA battery to power your camera (12.5V @ multiple amps available)! It would at least eliminate that possible problem. Also, check that you aren't losing any power with your cable to the camera - again, an over-spec'd cable would be good to use, in case. Just my tuppence worth! Paul. |

Thanks Paul. I will continue trouble shooting as the issues I am having are only occasional. I am thinking adding a Pegasus Power Box to see if that sorts things.

Try a usb 2 cable from the camera to the pc. I bet you'll never have another problem again.
