Even if they did the next test is with a insulation tester and here we need a 500 volt test voltage then just to completely stump you the RCD needs testing at 15ma, 30ma, and 150ma and the last test must be timed to see it does it in less than 40ms and I just can't see you operating a stop watch that quick. Be careful not to touch the other pins or the side of the connector while testing. You may need to look up a diagram of your DMX cable to find the polarity of the pins. Be careful not to touch the other pins or the side of the connector while testing.
