Sharp 4P-B86EJ2U Control


 

Hey All
Has anyone successfully gotten control via 232 or LAN? If so, how? We've been through all the display settings but can not get it to work, though it seems we are communicating. Same results via Putty - indecipherable Rx. Based on the Rx I would guess baud rate, but trying both 115 and 96 yields no better results.?
TIA


 

For what it's?worth, we did a takeover job with a Sharp? LC-60LE751K.

The only notable thing that I recall was that there was an RS232 to TTL converter between the COM port and the display.? Baud rate was 115200.

Power on/off were?POWR1\x20\x0D and POWR0\x20\x0D?respectively.

May or may not be applicable for your model, but hope it helps!


 

Just did one, going by memory, I think the commands were:
PWR[3spaces]1 then the CR, power off replace 1 with 0
the manual has all the info


 

CORRECTION POWR NOR PWR


 

ya, POWR? ?0CR and POWR? ?1CR is what we're using. Its acting like it isnt receiving a command however im getting responses in debugger and putty. feeling like its a setting in the display but we've been round and round with them


 

Baud rate 9600, the tv also has the ability to change the baud rate in the menu settings, you have to set that to 9600 too


 

yep. did that too. im kinda at a loss


 
Edited

When you said you¡¯re sending CR, you¡¯re not actually literally sending that are you? Should be \x0D (apologies if you knew that already!)


 

all good. yes, literally POWR? ?0\x0D and POWR? ?1\x0D. Going to resume work on this next week.?

My experience?with Sharp displays is that the power commands can be either "POWR? ?01\x0D" or "POWR1? ?\x0D" for POWER ON and "POWR? ?0\x0D" or "POWR0? ?\x0D" for POWER OFF. You may also have to send "RSPW1? ?\x0D" or "RSPW? ?1\x0D" once the TV is powered on manually to prevent the RS232 port from going into standby on power off. Unfortunately Sharp has been famous for changing the formatting even on the same model depending on when it was manufactured.?

"POWR? ?1\x0D"

Sorry, fat fingered.

I'm having this exact issue but with a 4P-B50EJ2U. Did you ever figure it out?


 

Hi Sean,

not sure if it applies to the 4P-B86EJ2U: we just received a Sharp display that allows selection of the RS232 protocol: "S" or "N" protocol.
The commands described above are "S" protocol, the "N" protocol is HEX.
Please check if there is a setting to switch between "N" and "S".
In addition you might want to check for Crestron Connected control. A firmware update on the display might be required to add this feature.

Best regards

Where you ever successful in gaining control of this display? I am working on one now and having the same issue. This display is obviously different in some way. I have controlled hundreds of Sharp displays in the past.?


 

Just did one a couple days ago and can confirm the commands for power are POWR___0\x0D and POWR___1\x0D.? The ___ are 3 spaces.? The displays did not acknowledge the power off command or acknowledge the power on command, but will respond to power query after a few seconds.?
