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!
***** 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?
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 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.
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)
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 :)

Great vid as always!
That was awesome very simple, nicely explained and demo.
Ha! I never thought to make one of those! Thanks!
Dude great video! I know its old but still awesome
very cool joe, thanks for sharing!!
Can i use it also as a microphone signal tester ?
Great Video Joe. Very interesting! :)
hello.. i would like to ask the configuration for the LED if you have an idea regarding the play and lightings? thanks
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?
What job does the resistor have?

Will this work with an audio signal
would this work with xlr cables
Great Video.
Hi, for XLR DMX terminal without led, is favorite the 120 or 110 ohm resistor ? Thanks

Simon Phillips im guessing you already resolved this?
Yes!

very usefull tips
Brill really useful, still pin 2&3 for a 5pin dmx plug?
yes
mi pui dire il valore della resistenza ?
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?
*****
thanks :)
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 ?
That was my question as well. Isn't this set up a 'Terminator Plug' because of the resistor?
Can i do it without resistor?
you can DO anything you want, but id not recommend it:)
