Consuming Electronic Control (CEC) Interface
Consumer Electronics Control (CEC) is a bi-directional communication, defined in the HDMI standard. This
feature is for remote control of the source and sink devices in the A/V system.
HDMI-TPS-RX220AK is able to send and receive CEC commands, from the input ports towards the source,
and from output port towards the sink. For more information about sending CEC messages, see the
(LW3 protocol commands) sections.
ATTENTION!
CEC has a dedicated pin in the HDMI connector. DVI connector does not contain this pin, so
the CEC transmission brakes when HDMI-DVI connector or adapter is in the signal route.
CEC Application Example
When active signal is detected on TPS in, the transmitter sends a CEC message automatically to the HDTV
to wake up.
Create an event in the event manager:
▪
Set as a condition, that the signal is present on the output (O1),
▪
Set as an action then send a CEC command 'Image view on' O1 output port.
See the details about the Event Manager settings in the
section.
ATTENTION!
The CEC command sending over TPS interface is working only with CEC-transparent TPS
transmitters. For the details please download our Using CEC in Lightware Devices document on the
https://lightware.com/support/guides-and-white-papers
website.
