I have several RX/TX receivers and an EX/RX receiver. They power up, Green data light is blinking and they are receiving the correct stream since a test light I have displays the right channels when I turn them on. The issue is that if I turn up a channel all the way, the test lights blink. It seem like the DMX transmission is getting interruppted. I have 1 TX/RX unit that is working flawlessly in Transmit mode. 2 TX/RX that are also working flawlessly. The issue is another two TX/RX and and EX/RX.
Any ideas on what I can check?
