Sharp Serial Port


 

I just had an instance where sending RSPW1\x20\x20\x20\n would respond with an OK but the serial port would not stay on after a power down.
Sending the same command but in Hex \x52\x53\x50\x57\x31\x20\x20\x20\x0D made it work, just an FYI.

Thanks,



 

The only difference there is your line ending.? Crestron turns \n into \x0D\x0A, while your second command only has \x0D (aka \r)? Some devices are flexible about line endings, but most are not.

I have recently ran into the same issue where the panel will not respond after the display is powered down. ?did you get any resolution?


 

I just ran into this yesterday where the RSPW1 would be accepted but would not turn on the display. ?There is a setting on the display called Quick Mode. ?When that was enabled, the display worked fine.


 

I believe that (in most cases) the RSPW1 command must be sent when the display is already on.


 

Thanks for the quick mode tip. ?my installers missed it. ?all good now.

In the power setting make certain the following are set:

Setup - Quick Start On

System Options - Power Control Off



It is also always best to update firmware.

Always send the RSPW 1 when the TV is on. ?I send it 1 second before power off every time.
