General Description

The simple un-expensive DMX Tester and Terminator will allow users to see if a device is properly sending or receiving a DMX Signal.   Also will work as a Terminator and prevents the fast DMX signal from bouncing back down the line and causing flicker and other problems.  It is safe to leave this product connected all the time.

How it Works:

Green LED:  The LED will blink back and forth green and red, but the green will over power the red.  If you see mostly green then is working properly. 

Red LED:  if you see red only then you have DMX signal problem such as inverse polarity.

No LED:  If the LED is off then you have pin 2 or 3 cut off.
