Still not working. Sold my ASIAIR Plus because of this. However, really need this device for a portable setup so bought a ASIAIR mini. Still doesn't work with that either with the same error. Just won't trigger an exposure. However, as mentioned above, using a cable to trigger the exposure works fine, but is a clunky and inelegant solution because it creates a situation where the cable release is pulling on the camera (the longest cable release I can find is 19" long) unless the ASIAIR is mounted to the camera, which also comes with negatives.
