RS232 HEX CODE FOR SONY AND LG DISPLAY

Hello,

I looking for the rs232 hex code to remote change the input of a Sony DIsplay from TV to HDMI and for tunring the screen on and off.

I stumbled on a site

http://files.remotecentral.com/library/3-1/sony/lcd_%282010%29_television/power_control/index.html

Can anyone help with the conversion method.

Thanks in advance

You don't need to convert the hex codes to get this to work.  All that is needed is to send the hex code to the monitor.

In System Task, create a new system task to turn on the monitors.  The Request type is Set and the Request is rs232.tx_hex= where the message string is the power on code (rs232.tx_hex=

0000 0067 0000 000d 0060 0018 0018 0018 0030 0018 0030 0018 0030 0018 0018 0018 0030 0018 0018 0018 0030 0018 0018 0018 0018 0018 0018 0018 0018 03f5) .  Create a second System task to turn off the monitors.

To test use the scheduling option to send the off codes to a monitor.  If all is correct the monitor should turn off.

Hope this helps

Hi jdedell12,

Was wondering if i could use the shorter codes?

rs232.tx_hex=6b622030312030300D

rs232.tx_hex=6b622030312030320D

** got the code above from the cisco support discussion; not confirmed it correct

THanks

Dear

i did not get your question , but if you have DMP which have HDMI port and your TV support HDMI , you will only need for HDMI cable , it is so different from RS232. Kindly find the photo of HDMI.

Thank you

hi,

What am trying to do is control the sony tv from the dmm using advanced task

To start with i can not control the TV using the format specified by jdedell12

i have both the hdmi and rs232 cable connected to the back of the display

Checking;

With the https:///get_param?p=rs232.*

rs232.device     T_STRING     /dev/ttyS0
rs232.speed     T_STRING     9600
rs232.parity     T_STRING     none
rs232.data_size     T_STRING     8
rs232.stop_bits     T_STRING     1
rs232.flow_ctrl     T_STRING     none
rs232.tx_hex     T_STRING     
rs232.tx_str     T_STRING     
rs232.rx_buf     T_STRING     
rs232.rx_overflow_flag     T_STRING     false
rs232.tx_cnt     T_STRING     0
rs232.rx_cnt     T_STRING     0

i have sent to rs232 on code to the display it restarts but the rs232.device still stays at /dev/ttys0

We had a terrible time controlling the screens using RS232 hex commands until we found out we were using the wrong RS232 cables. The official Cisco cable is DMS-RS232-CBL

NEC also makes a tool called PD Comms that you can use to observe device responses to hex commands. It's here

Good luck!

Yes I always use the RS232 cable that comes with the DMP.  So far no issues with that cable. 

Finding the correct string is always the issue as they are different by make and model.  For some models you need to first enable the RS232 commands using the monitor's menu screen.  On others I have found you need to set the device number to 1 from 0 again using the monitor's menu screen.

Good luck

Hello All,

I was able to control the TV from the com port of my PC. except turning on( ka 1 01 [Cr] ) and to  change the input  (xb 1 91 [Cr] )

The set I'D of the TV (LG50PA4500) is set to 1.

But when I connect to the DMP I couldn't control the TV atleast to turn off ( this i was able to do from the com port)

Kindly help confirm the hex code for;

On= Ka 1 00 [Cr]

Off = Ka 1 01 [Cr]

Change input = xb 1 91 [Cr]

Thanks for the anticipated prompt response

Regards
