On the job continuity checker
for XLR and BNC cable runs. Put the box at one end and a connector at the
other and the leds will tell you if there's continuity on the cable. XLR can
also check presence of phantom power in an audio run, and DMX pulses where
it has been run in a 3 pin configuration. BNC can check presence of H
or V sync pulses.
The XLR & BNC Cable Tracer
is an ideal tool for troubleshooting cable runs. Faulty cables can be
identified, and tie lines can be identified at each end of a loom. Saves
time in set ups where cables have already been run, and where it is
impractical or impossible to check continuity by other means.
