The DFD DMX512 Line Tester instantly displays the presence of the +Data and -Data signals when plugged into a DMX control line or feed-through connector. It serves as a perfect pocket sized tool for troubleshooting DMX512 cabling. Observing the indicators while fading all the dimmers from zero to full will detect if either line is stuck high. Swapped +Data and -Data lines can be determined by sending all dimmers to full.
