I have both USB and RS232 hardware box's. The usb box has worked fine with the 5 Star fixtures and smaller effects. When I cam to use it with some Coema ISPOT 575s that have a high demand on DMX channels I had some big issues, if the fixtures were set to anything but channel 1 then they became very very slow and iratic and lost time with each other, in most cases they hardly moved! I tried everything to get them to go ( different cables, different PC's etc.. and discovered it was the controller, after swapping back to the RS232 version all was fine. Any ideas?
