Page 32 / 107 Section 6. Operation of UMX-OPT-TX150R
6.6.1. Non-priority (first detect)
The device checks the DVI-D input first. If there is a valid video signal on the DVI-D input
it will be selected. If there is no video signal on the DVI-D input the device checks the
VGA input. If there is a valid video signal on the VGA input it will be selected. If there is
no video signal on the VGA input the device checks the HDMI input. If there is a valid
video signal on the HDMI input it will be selected. If there is no video signal on the HDMI
input the searching process starts again. The selected video input port remains active
while there is a valid video signal on it. If the selected input was unplugged or the valid
video signal was disappeared the searching process starts again from the DVI-D input. If
one of the input ports (e.g. VGA) was selected - and there is a valid video signal on
it - and a valid video signal was appeared on the other input port (e.g. HDMI) – by
connecting or powering on a video source - the searching process does NOT start again.
The previous selected video input port (VGA) remains the active one.
