I have a DMPS300, a slave MC50, an RMC-100 at each display, and 2 80" monitors. I am using a relatively standard Sharp Module and using basic commands, power, input, volume, mute. I would use the serial strings alone, but sharp does not offer the incremental volume commands, only a set numerical volume command. My RMC's have never gone offline nor have I lost video, but my commandsto the monitors get wacky sometimes. At times, i may loose commands going to either one of the TV's. They seem to lock up. In debugger, I can see the command strings going to them, along with all the polling from the module. When it freezes I either have to wait for it to "catch up" or do a reboot. Sometimes a RSPW1 command will snap it back in shape, but thats only when I'm there troubleshooting. I did notice a ton of chatter from the DMPS in debugger. I wish there was a way to turn off some of the processes I'm not using. Anyone have any insight?
