If you are using "prosumer" Sharp displays(sounds like it if you need the RSPW1 command), you need to severely limit the polling to the display, or yes, it will lock up. You then have to wait until it responds with the OK before sending any command. If you don't wait and keep trying commands, it will just stay locked up. So I don't poll it very often. Also, I have had to send the same power and input commands twice in succession to get these displays to operate reliably. I even send the RSPW1 command every time after a power on command, just to make sure it never goes back to the power save mode.
The pro Sharp PN-E displays have none of these problems.
You get what you pay for.

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?
