Look inside the unit. Look and listen for loose bits of metal inside. Screws or some tiny strands of copper leftover from it's last repair. Also the DMX board may have some weirdness with a blown component or a solder bridge.</div><div><br></div><div>Dale </div><div><br></div><div><br></div><div><div style="font-size:9px;color:#575757">Sent from my Verizon Wireless 4G LTE smartphone</div></div><br><br><div>-------- Original message --------</div><div>From: Stephen Litterst via Stagecraft <stagecraft@theatrical.net> </div><div>Date:03/17/2015 12:18 (GMT-05:00) </div><div>To: Stagecraft <stagecraft@theatrical.net> </div><div>Subject: [SML] DMX Troubleshooting </div><div><br></div>Dear hive-mind,<br><br>I ran into an unusual situation this weekend. I moved three of my wash <br>units from one electric to another. In the new location, they had no <br>DMX signal, despite everything being plugged in.<br><br>Going through them step by step, I discovered that it was the unit at <br>the end of the chain that was the issue. When it was plugged in to the <br>DMX line, all the units lost their data signal. When I would unplug it, <br>the two upstream units regained their signal. I swapped out the cable, <br>and had the same results. In the end, we swapped out the light with a <br>spare. (I'm amazed I had a spare, to be honest)<br><br>Any thoughts on what might have changed inside the light? This is a a <br>Coemar iWash Halo, not a common fixture and getting a bit long in the <br>tooth. It's not worth spending a lot of money on, but neither do I have <br>the money to replace all of them with something newer.<br><br>Thanks!<br><br>Steve L.<br>-- <br>Stephen Litterst Technical Operations Supervisor<br>litterst@udel.edu Mitchell Hall<br>302/831-0601 University of Delaware<br><br><br>____________________________________________________________<br>For list information see <http://stagecraft.theprices.net/><br>Stagecraft mailing list<br>Stagecraft@theatrical.net<br>http://theatrical.net/mailman/listinfo/stagecraft_theatrical.net<br></body>
