The MAC III Profile user manual from Revisions D to G contained incorrect information about setting pan and tilt limits by DMX on Channel 27 in Basic 16-bit mode and Channel 30 in 16-bit Extended mode to avoid collisions in the rig, for example. This error is corrected in the MAC III Profile user manual Rev. H.

The correct information is:

DMX VALUE         PERCENTAGE       FUNCTION
     60-64                    22-23                Set pan/tilt limit: head must stay inside defined limits (limits define safe zone)
    70-74                    26-27                 Set pan/tilt limit: head must stay outside defined limits (limits define no-go zone)

This correction only applies to setting pan and tilt limits via DMX. The user manual has had a correct description of setting pan and tilt limits using the fixture's control panel and display since the feature was released in the MAC III.
