The following information will help you troubleshoot in the event that your iPad does not recognize the DUO-CAPTURE MK2:
Be sure that the COMPUTER tab on the back of the DUO-CAPTURE MK2 is set to “TAB” and not "44.1" or "48". If this needs to be changed, disconnect the USB cable from the DUO-CAPTURE MK2, change the switch to TAB and then reconnect the USB cable to the DUO-CAPTURE MK2.
Be sure that you have updated the iPad to the latest version of iOS.
If you are using batteries, try brand new, unused batteries.
Try a different USB cable connecting the DUO-CAPTURE MK2 to the Apple iPad Camera Connection Kit or Apple Lightning to USB Camera Adapter.
Note: Due to low quality manufacturing, 3rd party camera connection kits may cause issues such as noise or inconsistent connectivity. Because of this, we recommend using Apple branded camera connection kits only.
