Also, just to make sure it's clear, I have a standard cat5 cable going from the ED to the LEv5. It is not a crossover cable, nor is it customized in any way. From what I read, without using a "combiner" in a reverse fashion, hooking up straight to an LE limits you to 512 channels (1 universe) which is fine. But it sounded like a straight cable going from the ED to the LE would work fine for those 512 channels, correct? Or do I need to make a custom cable... I didn't really see a spec on the pinout for the output from the ED, nor the input into the LEv5 beyond pins 1 and 2 being used for the DMX signal. Am I correct in assuming the ED sends out 4 pairs of DMX signals, including channels 1-512 on pins 1 and 2?
