Intermediate control systems such as the Martin Lighting Director (MLD) and the Martin Matrix must be bypassed when updating fixture software via the DMX link. These systems do not relay the update code correctly because it is not a DMX-compliant signal. This applies to all Martin upload devices: the MPBB1, MP-2, LightJockey DJ/Club 4064 DMX Interface, and the Case controller with version 7.3 or later software.

Remember to reconnect the DMX input and output after performing the update.
