Homemade DMX Tester

[CavezziMagnum]

Ok, I've made both 3-pin and 5-pin versions of these DMX Testers that are only testers and not testers/terminators. They are only good for testing if they is any signal coming through. Per tester I used (1) 270 ohm resister 1/2watt, 1 bi color LED (red/green), and some heat shrink-tubing and a bit of solder. It is more RED when there is a lot of signal going through (ex: controlling 3 moving lights at once), otherwise it is an orange-peach type color. It all fits neatly into the existing housing sent with the 3-pin connector.

Good Luck!

So I have to order some parts from an electronic store and thought I would order some LED's to make a couple of DMX testers, but when I pulled up the LED's on the Arrow website, it came back with 50,000 choices. I was hoping someone could help narrow down my selection. Are there some specifications I need to look for in an LED to put into the testers?

Thanks.
