RS-232 commands for a Sony TV connected to a DMP

Postby Guest » Wed Jul 14, 2010 8:30 am

Hi,

 

Has anyone successfully sent an RS-232 command from a DMP to turn a SONY LCD TV 32" or 40" on or off?

 

I have created the following commands in System Tasks:

 

Sony TV On :

Name : Sony Screen On

Description: Turn Sony Display On

Request Type: Set

Request: rs232.tx_hex=8C 00 00 02 01 8F (tried with spaces and without spaces between values)

 

I also tried Request: rs232.tx_hex=8C 00 00 02 01 8F 0D (0D Hex for carriage return) unsuccessfully.

 

Sony TV Off :

Name : Sony Screen Off

Description: Turn Sony Display Off

Request Type: Set

Request: rs232.tx_hex=8C 00 00 02 00 8E

 

I can confirm that the same command " rs232.tx_hex=" is set for the Panasonic Screens (hex value is different as below) and the screens do turn on and off successfully.

 

Panasonic TV On:

Name : Panasonic Screen On

Description: Turn Panasonic Display On

Request Type: Set

rs232.tx_hex=02504f4e03

 

Panasonic TV Off:

Name : Panasonic Screen Off

Description: Turn Panasonic Display Off

Request Type: Set

rs232.tx_hex=02504f4603

 

When I connect the same RS-232 cable used between the DMP and Sony TV to my laptop and to the Sony LCD TV and run a sendhex.exe command 8C 00 00 02 00 8E the TV does turn off, 8C 00 00 02 01 8F does turn the TV on.

 

The sendhex.exe was provided by Sony and I can see the underlying code but apparently all it does is send the hex value entered down the RS-232 cable.

 

Thank you

Linda,

 

My apologies, but:

 

* What versions of firmware are you running on the DMP (ie. 5.1, 5.2)?

 

* What model of DMP?

 

* What is the model# of the Sony TV?

 

thank you,

 

T.

Linda,

 

Sorry for the delay.

 

It does appear that the code strings are correct and you

have tested as you mentioned.

 

Please configure two custom Advance Tasks in

the DMM-Digital Signs Module

----------------------------------------------------------------------

Sony (Turn ON)

Set

rs232.tx_hex=8c000002018f

 

Sony (Turn OFF)

Set

rs232.tx_hex=8c000002008e

 

*  Once configured please attach the Sony LCD to a DMP and

test the strings above.

 

Also, you may want to try an Enquiry also to see if any is returned:

 

Sony (POWER Enquiry)

Get

rs232.tx_hex=830000ffff81

 

 

Please try and let me know what your results are..

 

Thanks

 

T.

I have had the same experience as Linda. I am running DMS 5.2 and trying to use Custom Advanced Tasks to turn my Sony FWD-40LX2 monitor on/off. Like LInda, I have been trying the following without success.

 

Sony (Turn ON)

Set

rs232.tx_hex=8c000002018f

 

Sony (Turn  OFF)

Set

rs232.tx_hex=8c000002008e

 

 

 

I have also had no success with the following enquiry command. I get a null response.

 

Sony  (POWER Enquiry)

Get

rs232.tx_hex=830000ffff81

 

 

Any help you can provide is much appreciated.

 

Jeff
