)
The decoders support CEC over IP, allowing control of a CEC (Consumer Electronics Control) enabled display through the HDMI
connection. The decoder receives the CEC commands and passes the commands through the HDMI connection to the CEC enabled
display. CEC commands may be triggered by the decoder web UI (System tab) or using API commands. The API uses references
commands to trigger the desired CEC action or control.
CEC-O-Matic (https://www.cec-o-matic.com) is a website that may be used to assist as a general reference when testing and
configuring CEC. Type the reference commands into CEC-O-Matic and it should decode reference and describe the specific purpose
or command for that code. The site can also assist when configuring the syntax of a new command.
Note: The TV/display has CEC enabled (Samsung calls it ). The setup menu of the display may be needed to enable this
feature.
