3 Overview
The VP-4x4Kis a true 4x4 matrix switcher for computer graphics (up to and
exceeding UXGA) signals and balanced stereo audio signals. The VP-4x4Klets
you simultaneously route any or all of the four inputs to any or all of the four
outputs.
In addition, the VP-4x4Kfeatures:
•A video bandwidth of 400MHz that ensures transparent UXGA performance
•DC coupled inputs and outputs
•A selectable delayed switching mode (ranging from 0 to 3.5sec1
•Audio gain control for the inputs and the outputs
) for clean
transitions (seamless switching) when switching between non-genlocked
sources
•Audio-follow-video and breakaway options
•Storing and recalling setup options
•A TAKE button for precise switch control that lets you execute multiple
switches all at once
•A LOCK button to prevent tampering with the front panel
•The ability to automatically detect connected input signals (the respective
button illuminates in green)
•Our innovative integrated sync processing; KRISP™ technology that lets
you achieve a sharp, stable image when the sync level is too low, by
restoring the sync signal waveform
Control the VP-4x4Kusing the front panel buttons, or remotely via:
•RS-485 or RS-232 serial commands transmitted by a touch screen system,
PC, or other serial controller
•The Kramer RC-IR3 infrared remote control transmitter
•The ETHERNET
To achieve the best performance:
•Connect only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noise
levels (often associated with low quality cables)
•Avoid interference from neighboring electrical appliances that may
adversely influence signal quality and position your Kramer VP-4x4K
away from moisture, excessive sunlight and dust

6.1 Connecting the VP-4x4K Rear Panel
To connect1the VP-4x4K, as illustrated in the example in Figure 2, do the
following2
1. Connect up to four computer graphics video sources to the 15-pin HD
INPUT connectors (from INPUT 1 to INPUT 4).
:
2. Connect up to four unbalanced stereo audio sources (for example, the
audio source of the computer3
3. Connect the four 15-pin HD OUTPUT connectors to up to four computer
graphics video acceptors (for example, displays).
) to the AUDIO INPUT 3.5mm mini-plug

6.5 Configuring the Ethernet Port
To configure the Ethernet port, you have to connect your PC to the VP-4x4K
either via the Ethernet (see section 6.5.1) or via a serial port. Once the
machine is connected, you can configure the Ethernet port.
6.5.1 Connecting via the Ethernet
You can connect the VP-4x4K via the ETHERNET in the following ways:
•For direct connection to the PC, use a crossover cable (see section
6.5.1.1)
•For connection via a network hub or network router, use a
straight-through cable (see section 6.5.1.2)
6.5.1.1 Connecting the ETHERNET Port Directly to a PC (Crossover Cable)
You can connect the Ethernet port of the machine to the Ethernet port on your
PC, via a crossover cable with RJ-45 connectors.
This type of connection is recommended for identification of the factory default
IP Address1
After connecting the Ethernet port, configure your PC as follows:
of the VP-4x4K during the initial configuration
1. Right-click the My Network Places icon on your desktop.
2. Select Properties.
3. Right-click Local Area Connection Properties.
4. Select Properties.
The Local Area Connection Properties window appears.
5. Select the Internet Protocol (TCP/IP) and click the Properties Button (see
Figure 6).

your desktop to the file.
Follow these steps to configure the port:
1. Double click the desktop icon.
The Connect screen appears as follows:
Figure 8: Connect Screen
2. Select the method to connect to the Ethernet port of the VP-4x4K.
Select:
Ethernet, if you know the IP address number or the machine name.
The default name for the machine is KRAMER_XXXX1
Serial, if you are connected via a serial port
3. Click OK.
