VS-48HDCPxl - Getting Started
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-48HDCPxl 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.

You can control the VS-48HDCPxl using the front panel buttons or remotely via:
RS-232 serial commands transmitted by a touch screen system, PC or other
serial controller
The Kramer infrared remote control transmitter
An external remote IR receiver (optional), see Section 3.3
The Ethernet port
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-48HDCPxl 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.

VS-48HDCPxl - Overview
3.3 Using the IR Transmitter
You can use the RC IR3 IR transmitter to control the machine via the built-in IR
receiver on the front panel or, instead, via an optional external IR receiver (Model:
C-A35M/IRR-50). The external IR receiver can be located up to 15 meters away
from the machine. This distance can be extended to up to 60 meters when used
with three extension cables (Model: C-A35M/A35F-50).
Before using the external IR receiver, be sure to arrange for your Kramer dealer to
insert the internal IR connection cable (P/N: 505-70434010-S) with the 3.5mm
connector that fits into the REMOTE IR opening on the rear panel. Connect the
external IR receiver to the REMOTE IR 3.5mm connector.

6.4 Changing the Port Switching Speed
The switching speed can be set per port to any of the following:
3—Normal (default)
2—Fast
1—Extra fast
To change the port switching speed:
1. Ensure that the device is in normal switching mode, (that is, not Store,
Recall or EDID mode).
2. Press the RCL and EDID buttons at the same time.
The RCL and EDID buttons flash, and the display indicates the switching
speed mode of each port.
IN 1, IN 2 and IN 3 are illuminated (red).
3. Press one or more (or ALL) of the OUT buttons to select the port to change.
The selected port setting on the LED display flashes.
4. Press one of the IN 1/IN 2/IN 3 button to toggle the switching speed, (to Extra
fast/Fast/Normal, respectively).
The switching speed displayed changes for the selected ports.
5. Press the LOCK button to confirm the change.
The switching speed for the selected port is changed and the device reverts
to the normal switching mode.
Note: If the LOCK button is not pressed within about 12 seconds, the device exits
the port speed switching mode automatically and all changes are lost.
6.5 Setting HDCP to On/Off
HDCP support can be enabled (On) or disabled (Off) for each of the HDMI inputs,
allowing the source to transmit a non-HDCP signal if required (for example, when
working with a Mac computer)

16
VS-48HDCPxl - Operating the VS-48HDCPxl 4x8 DVI Matrix Switcher
To set the HDCP:
1. Turn the power off on the machine.
2. Press and hold the IN 1, IN 2 and LOCK buttons simultaneously and turn the
power on while pressing these buttons (you will need more than one person
to perform this step).
The machine is set to the HDCP enable/disable mode.
The input front panel buttons’ status indicates the HDCP state of each input:
HDCP enabled (ON) on an input –that input button is illuminated
HDCP disabled (OFF) on an input –that button is not illuminated
3. Press an input button to change its status.
You can press one or more inputs.
4. Once you have changed the status of HDCP on the inputs as desired, press
the EDID to save the changes and exit the HDCP enable/disable mode to
return to normal operation.
Note: If the EDID button is not pressed within about 12 seconds, the device exits
the port speed switching mode automatically and all changes are lost.
6.6 Acquiring the EDID
You can acquire the EDID from:
One output set to one or more of the four inputs (see Section 6.6.1)
Different outputs set to different inputs (see Section 6.6.2)
The default EDID (see Section 6.6.3)
6.6.1 Acquiring an EDID from a Single Connected Output
To acquire or change the EDID of a new output display:
1. Connect the required acceptor to the output from which you want to acquire
the EDID.

6.6.2 Acquiring an EDID from Several Sets of Inputs and Outputs
To acquire the EDID from several sets of inputs and outputs (for example, OUT 1
to IN 1 and OUT 6 to IN 3):
1. Connect the required acceptors to the outputs from which you want to
acquire the EDID.
2. Press the EDID and STO buttons simultaneously and hold them for 3
seconds.
Both buttons flash.
3. Press the SELECT IN button to which the first EDID is to be copied (for
example, IN 1).
