quote:Indicators:
Each of the four output channels have a set LED indicators, a
red and a green. Without an incoming DMX signal the red LEDs
will function as a power indicator. When a DMX signal is applied
the LED’s will serve two functions:
1. These indicator will indicate pin polarity. A solid red LED will
indicate pin 3 is hot (positive). A solid green LED will indicate
pin 2 is hot (positive).
2. When shorted or bad cable is connected to a particular channel
the LED will turn off. This is useful to immediately identify
bad cables or lines.
Well this is from the latest manual from the elation website.
