Operation
Overview
The 3-Port True 4K HDMI Switch offers easy and flexible source device
selection with either the front panel pushbuttons, and remote control.
Note:
Whenever the VS381B is powered on and there is no video input source
connected, it automatically selects Port 1 as the active port (i.e., the Port 1
LED lights up). You may choose one of the methods outlined below to
select a different port as your active port.
The VS381B takes about 10-20 seconds to boot up and apply system
configuration settings when first powered on.
Manual Port Selection
To select an HDMI source device, press the port selection pushbutton on the
front panel to cycle through the HDMI sources connected to HDMI input port
1, 2, and 3.
Note: The port LED (green) light indicates which port is currently selected.
Remote Control Selection
To select a source device with the remote control, press the number button that
corresponds to the port the HDMI device is connected to. The corresponding
port LED lights up.
See IR Remote Control, page 7 for more details.
Alternatively, you may also cycle through the available source devices by
pushing the port up and port down buttons on the IR remote control.
Use the port up button to select the next available port in ascending order
(from HDMI input port 1 to HDMI input port 3).
Use the port down button to select the next available port in descending
order (from HDMI input port 3 to HDMI input port 1).
Note: Aim the remote control at the IR receiver located on the front panel of
the VS381B. For optimum performance, make sure there is a clear line-
of-sight between the remote control unit and the IR receiver.
VS381B User Manual

rotation sequence is HDM input port 1 to HDM input port 2 to HDM input port
3 to HDM input port 1.
The rotation sequence cycles through HDMI input port 1 to HDMI input port 3.
For example, HDMI input source connected to HDMI input port 1 will be
displayed when the HDMI input source connected to HDMI input port 3 is
removed.
