1x DMX Cable Tester

Application: In the performance site or project debugging, if some of the fixtures have unstable signals, or the fixtures are not controlled or unresponsive, you can use this signal line tester to test the signal, or test the signal line alone. You can use this signal line tester to test the signal or test the signal line alone. One end of the signal cable is connected to the signal output port of the console, and the other end is connected to this signal tester. 

Tip: During the test, it must be ensured that it is used in the context of the console's communication signals, and never allowed to test on a port other than the signal line. The refresh rate of each lighting console is different, so some testers may cause the LED indicator to flicker when testing the signal. (This does not affect the normal use of the tester)〉
