Make Your Own DMX Signal Tester 

YOU SAVED MY TIME I TEST ALL CABLES AND FIXTURES BEFORE EVERY SHOW BIG THANKS BRO IVE MADE ONE FOR DMX MALE AND FEMALE

Good video, not only useful for DMX cable testing but the actual footage had perfect angle, clarity and time..

Made it today and it works great! Thanks Joe :)

That was awesome very simple, nicely explained and demo.

god your good! Well done Joe great vid. I`m there now with dmxing, but the cable issues can complicate things and why does it always happen when your running short on time!

Dude great video! I know its old but still awesome

Ha! I never thought to make one of those! Thanks!

Great vid as always!

very cool joe, thanks for sharing!!

hello.. i would like to ask the configuration for the LED if you have an idea regarding the play and lightings? thanks

Great Video Joe. Very interesting! :)

Can i use it also as a microphone signal tester ?

This is soo cool and easy, I need to do it, thanks :)

Great video! Thanks, what size of LED do you recommend? 3, 5 or 10mm?

***** So you used 110 ohms resistor to test a DMX XLR Cable. If I wanted to make one for a Mic Cable, what would I need? 80 ohms or is that not the way it works?

Great Video.

What job does the resistor have?

Hey, often times I install a lot of LED bars for weddings and partys and sometimes I plug a cable and all the led bars starts to do random patterns and colors. The problem was the cable but if I plug this tester in that cable, what will it do?

Hi Joel. I'm setting up a dmx system using QLC software on a Raspberry pie. I've bought a basic dmx capable rgb lamp but I'm unable to control the lamp. The problem maybe the DMX interface for the RasPi. My question is if there is a voltage in the DMX output are we to assume that data is also present?

Hi, for XLR DMX terminal without led, is favorite the 120 or 110 ohm resistor ? Thanks

Yes!

Will this work with an audio signal

very usefull tips

Hi joe, i tried doing this using a 120 ohms as i could not get a 110 ohms resistor, but it didn't work. We use an input voltage of 220 - 230 AC here, does that mean i should be using a different rating resistor. Plz advice. Thanks.

would this work with xlr cables

Brill really useful, still pin 2&3 for a 5pin dmx plug?

Great!

Can I use this as a terminator? So basically 2-in-1? Because basically it's just a terminator with a LED in it, isn't it?

mi pui dire il valore della resistenza ?

Resistance value

ciao vorrei sapere il valore della resistenza in om per fare un connettore

cause of the resistor it does the job of a terminator to right ?

Can i do it without resistor?

its better to use a 2 colour LED, cathode to 1 (with a risistor*), and the 2 anodes to pin 2 and 3, this way you test all the signal wires instead of just 2 and 3, it is allso more fail prove.... *find out what is the right risistor there a a real simple formula: 120 Ohm minus risistance of the LED equals the resistance of the risistor (this is different for all type of leds)
