3 Overview
The VP-8x4AK is a high performance 8x4 computer graphics video matrix
switcher for high-resolution video and stereo audio signals. The VP-8x4AK
is HDTV compatible and let s you route any combination of inputs and
outputs.
In particular, the VP-8x4AK 8x4 VGA / UXGA / A udio Matrix Switcher
features:
• Kramer’s innovative integra ted sync processing; Kr-isp® technol ogy that
lets you achieve a sharp, stable image when the sync level is too low, by
restori ng the sync signal waveform
• A video bandwidth of over 360MHz that ensures transparent performance
even in the most critical applications
• 16 preset memory locations for quick access to common video and audio
configurations and audio gain status for each output
• Automatic detection of the connected input signals (the respective button
illuminates)
• A delayed switching mode (ranging from 0 to 3.5sec
1
• DC-coupled video inputs and outputs
) for clean
transitions whe n switchi ng between non-ge nlocked sources
• Audio-follow-video and breakaway options
• Eight stereo unbalanced stereo audio input signals on 3.5mm mini plugs
• Four balanced stereo audio output signals on 5-pin terminal block
connectors
• Audio level control butto ns for adjusting t he signal l evel of each input
and each output
• Measurement and indication of the audio level for each input and output,
in relative dB
• A TAKE button, which allows you to place multiple s witc hes in a queue
and then a ctivate t hem simul t aneous ly with one touch of this b ut ton
• A LOCK button to prevent tampering with the front panel
• Support for DDC (Display Data Channel) communication between selected
input 1 and output 1 high-density 15-pin H D conn ectors on pin s 12 an d 15
• Control via embedded Web pages
1 In increments of 0.5sec

Control the VP-8x4AK using the front pa nel buttons, or remotel y via :
• RS-485 or RS-232 serial commands (using Kramer 2000 and 3000
protocols) trans mitted by a touch screen system, PC, or other serial
controller
• The Kramer infrared remote control transmitter or infrared remote
extension cable transmitter (optional)
• The ETHERNET
The VP-8x4AK is dependable, rugged, and fits into two vertical spaces (2U)
of a standard 19” professional rack.
To achieve the best performance:
• Use only good quality connection cables
1
• Avoid interference from neighboring electrical appliances that may
adversely influe nce signa l quality and position your Kramer VP-8x4AK
away from moisture, excessive sunlight and dust
to avoid interference,
deterioration in signal q uality due to poor matching, and elevated noise
levels (often associated with low quality cables).
3.1 Terminology Used in this User Manual
Table 1 defines some terms that are used in this user manual:
Table 1: Terminology Used in this User Manual
Term
Definition
802.3
The standard specification for ETHERNET that is maintained by the Institute of Electrical and
Electronics Engineers (IEEE).
Dynamic Host Configuration
Protocol (DHCP)
Allows the network administrator to distribute IP addresses from a central point and
automatically send a new IP address when an Ethernet point is plugged into a different
network location.
Gateway A network position serving as an entry to another network. On the Internet, a node or
stopping point can be either a gateway node or a host (end-point) node.
IP Address A 32-binary digit number that identifies each sender or receiver (within a network via a
particular server or workstation) of data (HTML pages or e-mails) that is sent in packets
across the Internet. Every device connected to an IP network must have a unique IP
address. This address is used to reference the specific unit.
Local Area Network (LAN) Computers sharing a common communications line or wireless link, which often share a
server within a defined geographic area.
Media Access Control
(MAC) Address
A computer's unique hardware number (or address) in a LAN or other network. On an
Ethernet LAN, the (MAC) address is identical to the Ethernet address.
Transmission Control
Protocol/Internet Protocol
(TCP/IP)
The basic communication language or protocol of the Internet that breaks the message into
appropriately sized packets for the network, and can be used as a communications protocol
in an intranet or an extranet.

3.2 DDC Support
When establishing a VGA connection between a PC or laptop and a display
device, a set of parameters known as EDID is exchanged between them,
which is carried over the DDC channel. In some PC graphic cards and
laptops, this information exchange is essential for proper VGA OUT
operation.
3.3 Defining EDID
The Extended Display Identification Data (EDID
1
Note that EDID is s upported between the inp ut 1 and output 1 high-density
15-pin HD connectors on pins 12 and 15.
) is a data-structure,
provided by a displa y, to de scribe its capabilities to a grap hics card (that is
connected to the display’s source). The EDID enables the PC or laptop to
“know” what kind of monitor is connected to the output . The EDID includes
the manufacturer’s name, the product type, the timing data supported by the
display, the display size, luminance data and (for digital displays only) the
pixel mapping data.

6.4 Connecting a PC or Controller to the RS 485 Port
You can operate the VP-8x4AK via the RS-485 port from a distance of up to
1200m (3900ft) using any device equipped with an RS-485 port (for example,
a PC). For successful communication, you must set the RS-485 machine
number and bus termination.
To connect a device with a RS-485 port to the VP-8x4AK:
• Connect the A (+) pin on the RS-485 port of the PC to the A (+) pin on
the RS-485 port on the rear panel of the VP-8x4AK
• Connect the B (–) pin on the RS-485 port of the PC to the B (–) pin on the
RS-485 port on the rear panel of the VP-8x4AK
• Connect the G pin on the RS-485 port of the PC to the G pin on the
RS-485 port on the rear panel of the VP-8x4AK
6.4.1 Setting the VP-8x4AK
1. Set the VP-8x4AK unit to a Machine # other than 1, according to Section
6.8.
2. Set the RS-485 TERM DIP-switch (see
Figure 6 ) ON (for RS-485 Line
Termination with 120Ω) if it is the only machine being controlled via this
RS-485 line (if multiple machines are being controlle d, then only the last
one on the RS-485 line should be set to ON).
