I was able to program the complete Zidoo IP Protocol in Crestron, no issues at all. The IP protocol manual doesn’t have the DAC switch, DAC on and DAC off, strings. I have the UHD 5000 and I need to switch on and off the DAC. The rs232 manual has DAC switch, DAC on and DAC Off, but IP documentation no. I need to know what “sendkey?Key. “ “string”, should I use to control the DAC IP. Zidoo never, ever answered any of my emails. Anybody knows?
