Lightning Connector Notice
ID TECH has had to update the lightning connector component on iMag Pro II due to the previous connector going end-of-life. During the validation of the new connector, ID TECH found that certain legacy iOS revisions were not able to work with the pass-through charging feature of the device. Below is a chart indicating which revision of the iMag Pro II are affected, and which iOS versions are supported for each:

IDMR-AL30133 Rev J (and below)
