I did four Halloween shows this year with the PropController and its bigger brother the PropDimmer and all worked perfectly. I used the PropDimmer only because it has on-board DMX hardware because I needed to run a commercial dimmer pack (I ran out of time to build a DMX board for the PropController, but plan to do that next year). Three shows were static with the controller wired directly to the PC, the fourth was on my home network (PropDimmer had a static IP but the rest of the network was DHCP).
