2 Getting Started
We recommend that you:
Unpack the equipment carefully and save the original box and packaging
materials for possible future shipment
Review the contents of this user manual
Go to http://www.kramerelectronics.com/support/product_downloads.asp
to check for up-to-date user manuals, application programs, and to check
if firmware upgrades are available (where appropriate).
2.1 Achieving the Best Performance
To achieve the best performance:
Use only good quality connection cables (we recommend Kramer high-
performance, high-resolution cables) to avoid interference, deterioration in
signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
Do not secure the cables in tight bundles or roll the slack into tight coils
Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
Position your Kramer VS-48HN away from moisture, excessive sunlight and
dust
This equipment is to be used only inside a building. It may only be
connected to other equipment that is installed inside a building.

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-48HN 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 and extra fast switching modes allows for
fraction-of-a-second switching times when using high performance display devices
or when using a scaler on the video output.
