AH sorry forgot it was a MY DMX thread
simply go into the generic folder and select generic dimmer. it should be just a 1 channel profile and add as many of those for as many pars you have. and you can even re name them later on once they are added to the software. another thing is make sure the generic par profiles match the channels that you are using with the DP-DMX20L. Lt me know if you need me to elaborate. Sincerely,
