5.6. The CEC Tool
UMX-TPS-TX140-Plus, UMX-TPS-TX140K and WP-UMX-TPS-TX130-Plus-US models are able to send and
receive Consumer Electronics Control (CEC) commands. This feature is for remote control of the source or
sink device. CEC is a bi-directional communication via HDMI cable, in this case between the input port of the
transmitter and the source. #cec

Layout of CEC panel on the HDMI input port
The CEC panel is available on the port properties window of the HDMI input and TPS output ports.

ATTENTION! It can occur that the third-party device can receive, but not execute the command because
it is not supported by the product. Check the accepted commands in the documentation of the device.

INFO: The first 2x2 bytes of the CEC commands contains identification data of the source and destination
address. When the port is input, it is always 04 (from TV to Playback device 1.)., when the port is output,
it is always 40 (from Playback device 1. to TV).
