This makes sense based on the sequence of the dimmers that are functional. Have you pulled the modules/cards out and metered at the bus inside the rack? Double check that there is power at your disconnect/mainbreaker incoming feed at the load side. From there, work your way in to the rack and inspect and meter all power connections (at both sides if there is a breaker/fuse in-line). Keep working you way in until power doesn't meter and you should find the problem. Classic case of "High Impedance Air Gap". Some one mentioned a Single Phase/ 3 Phase switch... that probably isn't the case as that would give you 2/3 of the rack instead of the 1/3 you've got.

Control is an ETC Insight over DMX. Dimmers 1,2,7,8,13,14,19,20,25,26 work fine. Full control. So that's 10 out of 30. My gut says that there's a power problem on the other two phases. Metered the incoming power and everything reads fine. Any ideas? I'll be calling Lite-trol in the morning, but would rather not have to pay Steve Short to come out here (or send the rack in to him).

This makes > sense based on the sequence of the dimmers that are functional. True, but the fail-on of dimmer 5 puzzles me. It has power, otherwise it couldn't be stuck on. > Have you pulled the modules/cards out and metered at the bus inside the > rack? That's this morning's task. What's frustrating is that the rack has no buss bars. Every dimmer has an individual wire feeding from the breaker, and an individual wire returning to the neutral buss. But I'll meter each slot, as well as shuffling around the control cards. Thanks for the input everyone. I've got a few numbers to call when I get on-site this morning and pull this thing apart again.

After five minutes on the phone with Litetrol we figured out the problem -- The ME had addressed the rack incorrectly. On the LMI-RD racks, the addressing is counter-intuitive so it looked right to me, but wrong to the rack brain. Kevin at Litetrol had heard years ago the correct addressing and that solved the problem. Now to track down a manual for the rack so next time I can RTFM before panicking. :) Thanks again for all the swift responses. Steve L. -- Stephen C.

Well, I'm not sure how to address the rack as anything but dimmers 1-30, but the correct settings for that are 01, 05, 09. This is an LMI RD rack, *not* the L-86 racks. The L-86 racks at least have the formula written on the control card. Steve L. -- Stephen C.

It emulates a 12 channel two scene preset board using our USB to DMX converter. The program is completely usable as-is or you may modify it to suit your needs. You may download the program and/or source files from: www.interstellar.com/support.html Notes: 1. This program only works with the Model 4201 USB to DMX512 Converter. 2. If you've installed the optional serial port driver, it MUST be uninstalled before the using the demo program. To uninstall it, see your manual or contact me for assistance. 3. If you wish to modify this program, it was created using Microsoft Visual Studio 6.0 (C++) and WIN98DDK. If you need a copy of the DDK, please contact me for a CD (it's 44MB). As always, comments welcome. ---------- Jerry Durand Durand Interstellar, Inc. 219 Oak Wood Way Los Gatos, California 95032-2523 USA tel: +1 408 356-3886 fax: +1 408 356-4659 web: www.interstellar.com ------------------------------ End of Stagecraft Digest #52 ****************************
