some DMX input not working

Hi all,

A spooky thing is happening...

There is a compagnie with a console sending dmx into our gateway.

We use an AIP to send the data (adr 100) to sacn 36. This is not working.

We tested it on a simple dimmer and the dmx is coming thru.  If wo put it back into the gateway it does not got picked up by the gateway (net 3 response 4-ports)

With the dmx output on the ion it works. But with the output of the compagie it does not...

Where do i need to look?

With regards
