Whirlwind DMX35T

Plug a 3 or 5 pin XLR type cable into the corresponding SEND and RECEIVE jacks on the DMX 35 tester. Rotating the test knob through the 5 positions (3 for 3 pin XLR cables) “sends” voltage to the corresponding LED and pin of the cable connected to the SEND jack, through the cable and back to the pin and LED receiving the voltage at the RECEIVE jack. Rotating through all the positions will indicate how a cable is wired by lighting the corresponding SEND and RECEIVE LEDs. Cables with shorted conductors will light additional SEND and RECEIVE LEDs identifying which wires are shorted. Cables with open conductors will only light the SEND LED. The “SHELL TO PIN 1” LEDs will light if the shell of the XLR is connected to pin 1 of the XLR at either end.
