RS232 Serial commands for Cisco 32" LCDs

Answered Question
Sep 10th, 2010

Are the serial commands for power on/off for the Cisco 32" LCDs different than the 40" and 52" monitors?

The "rs232.tx_hex=aa11fe010111" for power on and "rs232.tx_hex=aa11fe010010" work fine on the 40"s but the 32"s do not respond to these same commands.

I know the 40" and 52" LCDs are Samsung. The 32"s appear to be LG so I would suspect the serial commands would be different as well.

I have been unable to find any documentation for the 32"s.

Thanks in advance

I have this problem too.

Doug,


Have you tried using the Control TV icon in the DMP Manager?

You can power on and off the Cisco 30" from here along with

other rs232 control commands.


You also could use wireshark to sniff the wire to

see what codes the DMM are sending the DMP.


Cisco 32"\LG - RS232.Control


To use the RS232 commands on the DMP the serial port must be set to ON and

be pointed at the /dev/ttyS1 device.


To check this create a System Task to check your settings using Task 5

below. If your serial port is anything other than /dev/ttyS1 use Task 1

to set it correctly.


TASKS

=====


1. Create a system task under application


use type "set"


name it "RS232 ON"


init.startService_rs232=yes&rs232.device=/dev/ttyS1&mib.save=1&mng.reboot=1



2. Create system task "RS232 OFF"


use type "set"


init.startService_rs232=no&rs232.device=/dev/ttyS1&mib.save=1&mng.reboot=1



3. Create system task "Cisco 32N LCD ON"


use type "set"


rs232.tx_hex=6B612030312030310D



4. Create system task "Cisco 32N LCD OFF"


use type "set"


rs232.tx_hex=6B612030312030300D



5. Check DMP RS232 Settings (This setting will allow you to check the RS232

settings)


use type "get"


p=rs232.*
