Here's a few hex dumps off the DMX line. A "K" represents a break.

Get Current Address:
K CC 01 18 4C 52 00 7A 18 46 47 44 00 40 30 00 06 01 00 00 00 20 00 F0 00 04 6D
K CC 01 1A 47 44 00 40 30 00 4C 52 00 7A 18 46 06 00 00 00 00 21 00 F0 02 00 01 04 72

Set New Address:
K CC 01 1A 4C 52 00 7A 18 46 47 44 00 40 30 00 07 01 00 00 00 30 00 F0 02 00 01 04 83
K CC 01 18 47 44 00 40 30 00 4C 52 00 7A 18 46 07 00 00 00 00 31 00 F0 00 04 7E

I've also attached a text file with a discovery sequence. (I cut off the last few packets at the end to reduce the file size). Note that this is an exhaustive discovery. There are a number of shortcuts you can take to speed up discovery.

There dumps are from a DMXter4 talking to a HES Studiopix fixture.
