Channel Weirdness

First off, thanks to all who provided assistance in my palette questions...I appreciate the help!

I have a new one!

I have a conventional fixture, dimmer 62 patched into channel 70. I have a mover, channel 91 patched into channels 301-318. This is confirmed through the patch tab. I can use ch 70 and bring the fixture up and down. Here is where it gets funky. When I operate ch 91 (the mover), it works, but ch 70 is brought up to a low level. It does NOT show that it is at ANY level in the "tombstone" view. When I take ch 91 out, ch 70 goes out as well. Again, *nothing* is patched into ch 91 other than the moving light .

Any thoughts! Thanks in advance,

Hi Pat,

To start troubleshooting, bring up ch 91 and then do [about] channel 70. This should show you what is affecting ch 70. You can also do [about]{address} 62 to see what is controlling dimmer 62.

If the console is not sending out any level info for dimmer 62 when ch 91 is up, then I would look at your DMX routing and termination. Some more info on the physical layout of the system would help there.

Thanks Todd,

I think there is something happening with the data as I have the dmx chain terminated and the rogue fixture is still...well...roguey. I went through the "about" and everything was clear. Some of my students originally cabled the electric and frankly it is a spaghetti mess of data cables. I am going to pull everything down and re-cable. Maybe I can find the problem then!

Thanks again,

I wonder why a data cable would cause a conventional to light up. When I see this kind of interaction with conventional fixtures I start looking at the neutrals. Just a hunch but check the circuit and any power cables for polarity issues.

Good luck,

Hal
