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
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=
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
Was wondering if i could use the shorter codes?
** got the code above from the cisco support discussion; not confirmed it correct
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.
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
With the https://
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
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.
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
I think these ae the LG ones
power on: ka 0 010D
power off: ka 0 000D
Volume control: kf 0 050D
Volume control: kf 0 070D
HDMI 1: xb 0 900D
RGB-PC: xb 0 600D
DTV: xb 0 000D
With my Set ID set to 1. i was able to control the LG screens using the following;
Power On -
Power Off -
Input Change -
