Not having worked with the Heat Shrink Mylar, I'm not in a position to comment on that, but I might have a budget saving suggestion. I don't know about other places, but here we have regional BOCES (Board of Co-operative Educational Services) campuses that serve the public school districts. Amongst other things, they offer vocational training - including Auto Body work. Our local BOCES campus has such an oven and it might be cheaper than a commercial body shop. I'm not sure that it would be long enough to hold an 18' long flat though.

When I installed our new (used) Dimming system, I installed an XLR-5 connector on the cabinet, and runs of control cable to the projection / spot booth and to FOH. I currently plug in whichever cable I need. I'm wondering whether they could both be hard wired into the cabinet or would the unused cable run cause "Termination" problems. I know that the downstream end of a DMX run needs to be terminated - what about the Upstream end? It's a Colortran ENR system if that makes a difference.

You are currently doing it the safe way, even if it is a little more trouble. While trouble is not certain with long runs of unterminated cable, the probability is very high, and the effects catastrophic. If you do this on a video distribution, an 11m spur will neatly and completely remove the colour sub-carrier. A bit longer in the US: this is for a 4.43MHz sub-carrier. As I rermember, the NTSC sub-carrier is about 3.8MHz, which would make the length about 13m. The upstream end will be terminated by the DMX sender, but since DMX receivers are sometimes daisy-chained, the termination is often optional. There is often a switch somewhere marked 'bridge/terminate'. Check your manual. The termination always needs to go at the end of the run.

We had no problems as long as you only used one port at a time. I don't know if this is the "approved" method, but it was what the installer did for us years back, and it has worked fine.

Well, 'need' might be too strong a word. IIRC, the Ex-hall is eight feet higher than than the Arena floor, so if you start pumping water in the Ex-hall, the Arena becomes a swimming pool. This is, of course, all based on the rumour mill here in Tucson, so any resemblance to facts, living or dead, is purely co-incidental.

This is not recomended for DMX and is said to cause problems. A neater solution would be a 2 pole, 3 position rotary switch to select the feed you want to go to the dimmer racks.

David... I have used a switch in the past and it seemed to work well. Another option is that if you dimmer rack has two DMX inputs you could use one for each cable and just address the inputs to allow them access to all dimmers. This is what I am doing with a dimmer rack. The "A" input is used for the console and the "B" input is used by the architectural system. It seems to work rather well. kyle dugger ------------------------------ Date: Sun, 19 Dec 2004 22:13:20 -0500 (EST) From: Stephen Litterst Subject: Re: DMX question In-reply-to: Message-id: <1514.172.139.140.94.1103512400.squirrel [at] 172.139.140.94> References: > --------------------------------------------------- > When I installed our new (used) Dimming system, I installed an XLR-5 > connector on the cabinet, and runs of control cable to the projection / > spot > booth and to FOH.

First thing to check is if the ENR system allows multiple DMX inputs. I think it was an available option, so hopefully whoever had them originally got that option. Failing that, I'd suggst a DMX merger from Pathway, or Doug Fleenor. This should ensure that there will be no termination issues between the used and unused line.
