SX10 and CEC TV control



I tried to control the TV from a SX10 via HDMI CEC but the TV(Toshiba 42XV635D) doesn't recognize the SX10 as a CEC device. The TV ist ok for CEC, I tested it with a DVD Player which is working.


Is there a list of supported devices or manufacturer for CEC compatibility?


best regards

Did you enable CEC mode on

Did you enable CEC mode on the HDMI port...   it is OFF be default... not sure why

We have pretty good luck with using CEC to wakeup and set standby on TVs once its enabled on the endpoint

Are you wanting to do more than use standby and wakeup with the CEC link? (e.g. change volume or input)

On the Sharp TVs we use... Aquos Link must be enabled on the TV

Hi juriss, thanks for your

Hi juriss,


thanks for your reply. I enabled it on the webserver, also checked the configuration in the CLI. Both shows it as enabled.


Most important thing for me is to switch on/off the TV and perhaps change the input port.


Do you use a SX10 with the Sharp TV?

I have used it on several

I have used it on several endpoints (SX20, C40, C60), but not with the SX10 yet..

The only function that I have used/tested is the standby/wakeup

My expectation is that since it runs TC7 level software, it should have the same functionality, however reality may differ from expectations.....

I have never been a fan of having multiple inputs on the TV...
(e.g. HDMI 1 = SX20 and HDMI 2 is DVD player and HDMI 3 = Satellite TV)

Users will switch it to the TV and leave it on that input, then an inbound VTC call get no ringing and its a trouble....   or someone tries to make an outbound call and get no display need to have the users use the TV remote with 30 buttons and they cannot find the one button they need (input or source)

I do not see how the SX10 would know when to send the "Change Input" command to the TV over the CEC link

I like to leave the TV on the input that connects to the VTC system and connect other sources to the codecs spare inputs... (works with C40/C60 but not so with the SX10)

There are problems with connecting other signal sources to the codec via HDMI... like HDCP

Thanks Chris, It seems Cisco

Thanks Chris,


It seems Cisco has been bringing this up with LG for sometime now.

I am not aware, if you do not

I am not aware, if you do not get a better answer here, maybe you could ask your Cisco Partner / Contact or Cisco TAC and let us know what the result was.

Not sure about the handing of CEC anyhow, there is a option for the CEC and that at least is currently not supported if I look into the SX10 TC7.1 admin guide:


Video Output Connector [1] CEC Mode

Not supported in this version.

On Oct 8th Cisco provide the TC 7.2.1 Version with CEC support for SX10.

I just uploaded the version and it's working! TV switch on and off with the SX10 and even changes the input source to the SX10. Tested device was a Toshiba 42XV635D.

ChristianThanks for the


Thanks for the update, I have always felt that it should have worked from the initial release that supported the SX10...

I'm interested in how the imput change works...

Are you saying that...

- SX10 is on the HDMI 1 input on the LCD display

- Another HDMI source (e.g. DVD player) is on HDMI 2

- If the LCD is on HDMI 2 and the SX10 receives and inbound call... it will use CEC to switch the TV input to HDMI 1?


That is pretty neat... we have that "Wrong input" issue a lot and we try to discourage user from using more than 1 input

I have the same problem with

I have the same problem with the SX10 with firmware 7.3.1 and a Toshiba TV.
Little 35$ chromecast is able to to turn on the tv and select the input by CEC.

this is the latest firmware available so there is not any way to make it work.
