4. Device Concept
4.5.6. Consumer Electronics Control (CEC) Interface
DIFFERENCE:
This feature is available only in UMX-HDMI-140-Plus model.
Consumer Electronic 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.
UMX-HDMI-140-Plus model is able to send and receive CEC commands, on HDMI IN (I2) port towards the
source, on HDMI OUT (O1) port towards the sink.
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 DP in, the switcher 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
4.6. Further Built-in Features
4.6.1. Device Cloning – Configuration Backup and Restore
The device (configuration) cloning of UMX-HDMI-140 switcher is a simple method that eliminates the need
to repeatedly configure certain devices to have identical (non-factory) settings. If the devices are installed
in the same type of system multiple times then it is enough to set up only one device to fit the user's needs
and then copy those settings to the others, thus saving time and resources.
See more information about the settings in the
Event Manager section.
Backup (Configuration Cloning) section.
