AL5001 Evalution DMX Support

[VideoPlus]

Hi,we just got to card of this model and our problem is that
we got 3 different DMX models.BOTEX MPX-405,NEO-NEON DMX,LITE-PUTER DX-4020A.
So,AL5001 only working stable with one,NEO-NEON DMX.
My question is,where is the problem? in DMX models or AL5001 NOT supporting
every DMX model?
By the way,2 other models when connected to AL5001 EVO,power signal not stable from them,the light jumps ON and OFF every 5 sec.

Thank You.

Did you check whether these fixtures are really complying to DMX-512 USITT 1990 or DMX512A? Many cheap fixtures can't handle the speed, RDM packets, or don't comply to the levels of RS485.
