Hi Tomas and Jeff, I have tried executing the suggested commands and still no luck. When I executed the enquiry command:Sony  (POWER Enquiry)Getrs232.tx_hex=830000ffff81 I received the following dialogue in a new browser session but no actual response: http://<user id>:<password>@<DMP IP address>:7777/get_param?rs232.tx_hex=830000ffff81===========================================10:06:50 AM=========================================== When I ran the screen Off command (TV was on):Sony (Turn  OFF)Setrs232.tx_hex=8c000002008e Screen didn turn off.  I opened a browser session and added the following: http://<DMP IP Address>:7777/get_param?p=*.*:and could see the command in the output:  rs232.tx_hex     T_STRING     8c000002008e I also checked to ensure the rs232 service was enabled: init.startService_rs232     T_STRING     yes So it appears that the commands are being passed to the DMP. Im going to try another test where I connect the rs-232 cable from my laptop to the DMP and Ill send the command using hyperterminal to see if the DMP will respond.  Ill let you know the outcome in a few hours as I have to go to another building to perform the test. Cheers

Gentlemen, I ran the following test as suggested by Chip (Cisco Support) and the outcome wasn as I had hoped. 1) Connected my Windows laptop to one end of the rs232 cable and theother end to the DMP 2) Opened up hyperterminal on my Windows laptop and set it to usethe comm port of the laptop with 9600, 8, n, 1, with no flow control 3) Used a browser to send the following command to the DMP connected to:http://<ip address>/set_param?rs232.tx_hex=8C000002008E   What I was hoping to see was a response from the DMP on the hyperterminal but unfortunately all I saw was a blank screen. I ran the following command on a new browser to see the output : http://<dmp ip address>:7777/get_param?p=*.* and could see the following lines in the output as expected: init.startService_rs232 T_STRING yes  rs232.tx_hex T_STRING 8C000002008E Not sure what else to try.  If you have any ideas, please let me know. Cheers

All-We are successfully controlling a Sony FWD-40LX2F monitor by creating two custom Advance Tasks in the DMM-Digital Signs Moduleusing the following RS232 code and a "null modem" cable. Sony (Turn ON)Setrs232.tx_hex=8c000002018f Sony (Turn OFF)Setrs232.tx_hex=8c000002008e Jeff

Hi Jeff, Can you tell me what you did to get your commands to work as you had the same problem as me until your last post? Also, is it possible to send me a copy of the output after you execute your command (either to turn the TV on or off)?  You can get the output by entering the following into a browser? http://<dmp ip address>:7777/get_param?p=*.*  where <dmp ip address> is the IP address of your DMP that you are using to control the TV. I would like to see if your DMP is configured differently to mine. Many thanksLinda

Linda, 1.) I created an Advanced Task to turn RS232 On and Off as follows: "RS232 ON"request type = "set"request=  init.startService_rs232=yes&rs232.device=/dev/ttyS1&mib.save=1&mng.reboot=1 "RS232 OFF"request type = "set" request =  init.startService_rs232=no&rs232.device=/dev/ttyS1&mib.save=1&mng.reboot=1 2.) Then I connected my DMP to the Sony FWD-40LX2F monitor using a "null modem" cable. 3.) I sent the "RS232 ON" command to the DMP. 4.) Then I ran the https://<dmp ip address>/get_param?p=rs232.*  in by browser to confirm the port was on. Your results should be: rs232.device     T_STRING     /dev/ttyS1rs232.speed     T_STRING     9600rs232.parity     T_STRING     noners232.data_size     T_STRING     8rs232.stop_bits     T_STRING     1rs232.flow_ctrl     T_STRING     noners232.tx_hex     T_STRING     rs232.tx_str     T_STRING     rs232.rx_buf     T_STRING     rs232.rx_overflow_flag     T_STRING     falsers232.tx_cnt     T_STRING     0rs232.rx_cnt     T_STRING     0 5.) I was then able to send the following command to the monitor via the DMP.Sony (Turn ON)Setrs232.tx_hex=8c000002018f Sony (Turn  OFF)Setrs232.tx_hex=8c000002008e  6.) I ran the following in my browser to get the results that I have attached to this response as DMP.txt http://<dmp  ip address>:7777/get_param?p=*.*   I hope this works for you.Jeff
