Device Control Triggered
Display power control can be triggered by the wall plate Display button or from a source being detected
or no source being active. The Display button will send out a power on command when pressed and
released.
It will only send out the power off command when the Display button is pressed and held for
5 seconds
. CEC control is enabled for both Auto power and the Display button by default. Advanced
users can program RS232 Serial control to be triggered by the Display Button or Auto power via API
commands while connected to either the front panel micro-USB or RS-232 connector on the back of the
TX or RX. (API commands for the control can be found in a separate document.)
