flickering problem with 20k dimmer

Turned on LightingTurned on Lighting Registered User
I have 8 20k dimmers and one is flickering very badly. I made sure the line was terminated and also tried it's own line off the opti. After reading some here I also added a dummy fixture patched into address 512 then even soft reset the DP2000. Does anyone have any suggestions? by the way, I also did swap the dimmer with one that was working fine on another light and got the same problem.

    also as a note. It worked fine when we were running it through Dragon Image Capture software dongle.

    Yeah, their bad too. I've had issues with older model 20K dimmers flickering like you say. It's basically the old chip set in the dimmer not up to par with the newer data from the Hog. I've had conversations with Strand about this. Not much came out of it. So what I do now is run the DMX from the DP thru a DMX converter(or conditioner), like the Pathway DMX Ultimate Converter. It's real purpose is to convert old data to DMX512, but this works too...and it complete eliminates any flickering.
    DMX testers will work too. I have a Gizmo, and if I run the data thru the Gizmo, it does the same thing.

    Scott, What mode do you run your Gizmo in? Are you using its "Patch Mode", or how do you set it up?

    I didn't realize the Gizmo did that. I pulled mine out, and found that it receives the DMX on its input, and re-transmits the data with more conservative timing. I'd always assumed that it just buffered the signal unless you were in Patch mode.

    I learned something today. Thanks!

    I just talked to someone with Doug Fleenor Desgins and they said they are coming out with a simplified version of the Pathway that will solve this problem with the 20k dimmers call a DMX Decelerator. Retails for about $200. Did anyone see these at LDI?

    I saw it, or something that sounds simlar... Don't remember what it was called, but same basic premise. It's supposed to slow the timing for 'less expensive LED fixtures' to reduce flicker.
