jexjexjex Posted August 27, 2009 Share Posted August 27, 2009 Hi All. I've just had a user on the phone with what I think is a DMX issue that I could use a few pointers on. They're using a DMX Betapack1 that's being operated by a Strand 200 and there have been no problems with the kit until today. Normally, the pack hads been powered up before the desk and there have been no issues, but tonight for some reason, the desk was powered up first. When the pack was fired up, and all the channels came up full even though all the faders on the desk + the grand master were set to zero. After shutting down everything and reverting to "normal switch on order" everything is OK. Anyone shed any light on what may be happening? I should point out that the pack is one of a pair, is operating Ch.7 to 12 and the DMX line runs into this pack first. The other pack is giving no issues. All input greatfully accepted.

TimmyP1955 Posted August 29, 2009 Share Posted August 29, 2009 Swap the addresses and the connection order of the packs, and see if the problem stays with the pack or stays with the particular position & address set. Link to comment Share on other sites More sharing options...
k.gen04 Posted August 29, 2009 Share Posted August 29, 2009 Is the DMX line run NOT with mic cable, but DMX cable? Has the end of the DMX line been terminated with a 120 Ohm resistor between the data + and -? Link to comment Share on other sites More sharing options...
