3.1 About Fast Switching
Older display devices required a longer time between the loss of one digital signal
and the introduction of another, as well as a physical disconnection of the
interconnecting cable in order to be able to detect and adjust to the new video
attributes and parameters. Normal switching, therefore, introduced a 5V signal
disconnection along with a delay in switching. Many newer display devices,
however, are now capable of “on-the-fly” switching.
Depending on the display device in use, the VS-611DT allows for fast switching
(minor reset and the connection kept alive) and extra fast switching (no reset and
the connection kept alive). Using the fast switching mode allows for fraction-of-a-
second switching times when using high performance display devices or when
using a scaler on the video output.

priority input source. The default priority is Input 1 then Input 2.
5.1.3 Manual Override Mode
Auto switch mode can be overridden by a manual command, such as pressing an
input button or sending a control command. In such a case, the system switches to
the manually selected source. If this manually selected source is not active, the
system waits a set amount of time (10 seconds, default, adjustable on the Web
page) and then switches back to Auto mode. Manual override selection is not stored
in non-volatile memory.
A step-in command is considered a manual switching command.
5.2 Performing a Factory Reset
Factory reset returns all the parameters of the device to their factory default
settings.
To perform a factory reset:
1. Disconnect device power.
2. Press and hold Input 1 while reconnecting device power.
