Introduction
Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world
of unique, creative, and affordable solutions to the vast range of problems that confront the
video, audio, presentation, and broadcasting professional on a daily basis. In recent years, we
have redesigned and upgraded most of our line, making the best even better!
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 www.kramerav.com/downloads/VS-44H2A to check for up-to-date user manuals,
application programs, and to check if firmware upgrades are available (where appropriate).
Achieving 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-44H2A away from moisture, excessive sunlight and dust.
Safety Instructions
Caution:
• This equipment is to be used only inside a building. It may only be connected to other
equipment that is installed inside a building.
• For products with relay terminals and GPI\O ports, please refer to the permitted rating
for an external connection, located next to the terminal or in the User Manual.
• There are no operator serviceable parts inside the unit.
Warning:
• Use only the power cord that is supplied with the unit.
• Disconnect the power and unplug the unit from the wall before installing.
• Do not open the unit. High voltages can cause electrical shock! Servicing by qualified
personnel only.
• To ensure continuous risk protection, replace fuses only according to the rating
specified on the product label which located on the bottom of the unit.

The Input button contains the following elements:
• Name (in Figure 16, the name is HDMI1).
• Signal status (either “No Signal” or “Signal Lock”).
• Edit Input icon to edit the Input button name, set input HDCP behavior (i.e. designate
whether input device supports HDCP), or set Step-In functionality (see Setting Step-In
Devices on page 33).
• Switch Video icon to switch a selected output to this input.
• Remote device setting to manage a Step-In device (for example, Kramer DIP-30)

Changing Input Name
It may be convenient to change input names to reflect the video sources connected to them.
To change input name:
1. In the Navigation pane, click Switching.
The Switching page appears (Figure 11).
2. Click the Edit Input icon from an Input button (Figure 16).
The Input Settings group appears (Figure 17).
3. Type a new name (up to 11 characters) and click Save .

3. Set input HDCP to On/Off.
Input supports an HDCP device if HDCP is set to On.
There are video sources (e.g., some Apple devices) that automatically switch to
HDCP mode if connected to a device that supports HDCP (e.g. VS-44H2A). If an
acceptor/display connected to VS-44H2A does not support HDCP, you might want
to set Input HDCP to Off, so that the video source does not auto-switch to HDCP
mode and the acceptor does not display the video.

Protocol 3000
Kramer devices can be operated using Kramer Protocol 3000 commands sent via serial or
Ethernet ports.
Understanding Protocol 3000
Protocol 3000 commands are a sequence of ASCII letters, structured according to the
following.
• Command format:
Prefix
Command Name
Constant (Space)
Parameter(s)
Suffix
#
Command
Parameter
<CR>
• Feedback format:
Prefix
Device ID
Constant
Command Name
Parameter(s)
Suffix
~
nn @ Command
Parameter
<CR><LF>
• Command parameters – Multiple parameters must be separated by a comma (,). In
addition, multiple parameters can be grouped as a single parameter using brackets ([
and ]).
• Command chain separator character – Multiple commands can be chained in the
same string. Each command is delimited by a pipe character (|).
• Parameters attributes – Parameters may contain multiple attributes. Attributes are
indicated with pointy brackets (<…>) and must be separated by a period (.).
The command framing varies according to how you interface with the VS-88UT. The following
figure displays how the # command is framed using terminal communication software (such
as Hercules):
