Hope this is not too late, but I just found info from Rich at Dove when I had an issue with submasters not recording on a TechMaster a few years ago.If submasters are not recording because the “RECORD” indicator will not go out, and if it is not a defective submaster slide pot, it may be that...

I don't have the schematic but here is a spec sheet.

Rich Howe is your man at Dove Systems. Great guy and always very helpful. Give him a call at 805-541-8292. Do you mean that you can no longer record on any of the submasters (to the left of the master fader and crossfader) or that you cannot bring anything up using the the X or Y rows of faders...

Yep, adding the diode does appreciably increase the delay. Thanks for continuing to think about this! I did test with two different controllers and varying number of active channels; circuit seems to work just fine now.

I tried this and it didn't stop the chattering, BUT, I changed the capacitor to 10mfd and it seems to work great...very solid relay triggering. Will continue testing with a different number of channels up at different levels to make sure it will perform consistently. Then will have to take it...

Yep, good ol' Forrest Mims, circa 1996. Here is my collection:

So in my quest to come up with a DMX-sensing relay by spending $500 in my labor vs. $296 for the ETC CSR-D unit, I have built the following light-sensing relay circuit which turns on a relay when light hits the LDR (Light Dependent Resistor). It works quite well.My idea is to use the classic...

Received word today from the owner that Teatronics is still alive, just having some website and telephone issues. Website is back up now.

Great info, thanks so much!

I saw their website was still active a year or two ago after I found out the owner had died. Thinking someone had taken it over, I ordered some stuff. No communication and no merchandise. I should have called first but didn't. PayPal refunded my money.

My use case: I have two sources of DMX in a small theatre. A conventional 48-channel console with manual faders and a Fleenor PRE-10A remote preset panel. All the lights are conventional, but I am going to install some DMX "strip lights" to light a cyc, which probably won't get used a whole...

Does anyone know of a small pc board (like the cheap import 3-channel DMX relay boards) that is not DMX address based? I need a unit that will activate a relay as long as the DMX stream is present. Northlight used to make one but they are out of business.

They are impossible to interchange. The Colortran i96e series is physically about 3/4" wider and 1 1/2" deeper than the ETC D20. See comparison photos below. The Colortran module is the gray one.

I know the owner of Teatronics (not Teatronix) but have not talked to him for quite a while. If you will PM me, we can compare phone numbers. Looks like their website is down. Hope nothing has happened to him.

I've had good luck with the Altman SpectraCyc 200. You might think about getting demo units in for a shootout.
