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 neighbouring electrical appliances that may adversely
influence signal quality
•Position yourVS-1616D 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.
Kramer engineers have developed special twisted pair cables to best match our
digital twisted pair products; Kramer’s BC-UNIKat shielded twisted pair (U/FTP)
cables. These specially built cables significantly outperform regular CAT 6 and
CAT 7a cables.

2.5 About Fast Switching
Older display devices require 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 accepting “on-the-fly” switching.
4 VS-1616D – Getting Started
Depending on the display device in use, the VS-1616D allows for fast switching
(minor reset and the connection kept alive) and extra fast switching (no reset and
the connection kept alive), see Section 7.2.4
modes allows for fraction-of-a-second switching times when using high performance
display devices or when using a scaler on the video output.
2.6 About HDBaseT™ Technology
HDBaseT™ is an advanced all-in-one connectivity technology (supported by the
HDBaseT Alliance). It is particularly suitable in the consumer home environment as
a digital home networking alternative where it enables you to replace numerous
cables and connectors by a single LAN cable used to transmit, for example,
uncompressed full high definition video, audio, IR, as well as various control
signals.
The products described in this user manual are HDBaseT certified.

5.1 Port Numbering
On all cards apart from the DVI dual link cards, there are two physical ports on
each card and numbering of ports is sequential from top to bottom and left to right.
Each DVI dual link card provides one physical port which causes the loss of one
number in the numbering sequence of that card only. A sample numbering is shown
in Figure 5

as single digit numbers. When entering a single digit number (for example 5), you
can either press 0 followed by 5, or 5 followed by ENT.
Pressing 00 (or 0, ENT) is only relevant for an input and is used to disconnect the
currently entered output number from the input.
For example, the following display indicates that outputs 8 and 12 are disconnected
from any input (note that the corresponding inputs in the second line are blank):
The ESC button is used to cancel an operation without affecting the current status.
For example, if you enter an incorrect number by mistake, press the ESC button to
cancel the operation.
At any stage, if no button is pressed within approximately 15
seconds, the automatic timeout causes the VS-1616D to exit the
