i dont know about this model but i have 3 of the CX995V units ...there isnt a way to daisy chain these units so what i had to do is, i bought an IR controlled Video switcher that had descretes for each input as well as power, ...i also have thumbnail pictures of all my movies using the mx-3000....in the macro string for each thumbnail it will select the proper input to switch to. you can also utilize the 3 different IR codes that the unit has that way there is no crosstalk between units...works for me like a champ.
