Note:
The automatic switching function can detect the input signal with 5V only. If the selected
source in standby mode provides a continuous 5V power output, this function will not work, i.e.,
the transmitter will not switch the input to other active sources. In this case, please turn off the
selected source in standby mode or remove it from the transmitter.
Device Control
Advanced users can control the transmitter via API command through UPDATE port: connect a
control PC to the UPDATE port of the transmitter (see the following figure). API command for
device control is available in the separate document “API Command Set_EX0101-N008-
H20&H21”. A professional RS232 serial interface software (e.g., Serial Assist) may be needed
as well.
Before sending the API command to control the transmitter, ensure the transmitter and control
PC are configured correctly.
