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.


  • I changed the chip and the block itself, the side of the 3.4 port itself does not work, and everything is fine in the settings, several times the reset did not help
