Reply to "Dongle, no output"

An update on this fault if it helps anyone else.

The circuit diagram shows Q1 an ESD device across both output lines and with a ground connection. I suspected it had done its job with the ultimate sacrifice so I lifted the ground pin from the SM device and I'm pleased to say we've now got good DMX output from the dongle.

Next step is to replace the duff diode with a PESD5V0L2BT, similar device and readily available then give it some soak tests.

One observation, the 'DMX indicator' LED between the XLR's is driven from the processor chip and bears no relation to whether there's good DMX at the output sockets.
