Gateway 4 port

Hello. I have a 4 port gateway, 3.4 port does not give an dmx signal, everything is correct in the settings, physically swapped places 1 and 4, port 4 works on port 1. Can I fix it?

  • Hello Rafael,

    You may be able to repair this by replacing the DMX chip. If you remove the silver screw on the top of that module you'll see a black chip like the picture below.

    You can pull that out carefully with a small pair of pliers. Note where pin 1 is, it's marked on the chip with a small black dot. If you move the chip from a  working one to a non-working one, and that fixes the problem, the chip has been damaged. You can buy new chips from our web store:

    Or many electronics suppliers.
