Hey guys quick question, We are custom automotive shop and have a toyota sienna we turned in a personal limo for a client. i have a kp4000 in there now which controls everything including the power seats by using a bunch of cc62's. The client wants to add motorized curtains and also operate with the kp4000 which is not a problem but being as the do not make the cc62 anymore i just sorced out a 12 relay board with ir remote i wanted to make a button on the 4000 that will open or close all the curtains at one time (there Are 5) is the a way to send 5 ir codes at the same time without closing one then the other and so on?
