This is an Elation Wi-Fi transceiver. I connected the DMX cable directly to the device, and it worked correctly. So, I identified that the issue is with the transmitter. However, today, I was thinking about how to solve it because the transmitter only allows changing Wi-Fi signal transmission addresses. But changing the addresses didn't help.
Completely by chance, I found this error on the fixtures. In the "Edit Fixtures" section, I reloaded the fixture file from the library, and everything started working.
By the way, in firmware ZerOS Version 7.13.2, I have a bug where the indicator for the fader page keeps flashing all the time.
