3 Overview
The VP-8x8TP is a high performance 8x8 computer graphics video and audio
matrix switcher for high resolution video and stereo audio signals. The VP-8x8TP
is HDTV compatible and lets you route any combination of inputs and outputs over
TP (Twisted Pair) cable to compatible TP receivers.
In particular, the VP-8x8TP 8x8 UXGA/Audio Matrix Switcher features:
•Kramer’s innovative integrated sync processing Kr-isp®technology that lets
you achieve a sharp, stable image when the sync level is too low, by restoring
the sync signal waveform
•Resolution up to UXGA (1600 x 1200), 1080p
•Support for component video with suitable breakout cables1
•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
lights)
•A delayed switching mode (ranging from 0 to 3.5sec2
•DC-coupled video inputs and outputs
) for clean transitions
(seamless switching) when switching between non-genlocked sources
•Audio-follow-video and breakaway options
•Eight stereo unbalanced audio input signals on 3.5mm mini jacks
•Eight RJ-45 STP/UTP output connectors
•Over 100m (330ft) transmission range between the switcher and the TP
receiver
•Audio level control buttons for adjusting the signal level of each input
•Measurement and indication of the audio level for each input and output, in
relative dB
•A TAKE button, which allows you to place multiple switches in a queue and
then activate them simultaneously with one touch of this button
•A LOCK button to prevent tampering with the front panel
The VP-8x8TP can be controlled using the front panel buttons, or remotely via:
•RS-485 or RS-232 serial commands (using Kramer 2000 and 3000 Protocols)
transmitted by a touch screen system, PC, or other serial controller
•The Kramer infrared remote control transmitter or infrared remote extension
cable transmitter (optional)
•A Web browser over Ethernet
The VP-8x8TP is dependable, rugged, and fits into one vertical space (1U) of a
standard 19” professional rack.

To achieve the best performance:
•Use only good quality connection cables1
•Avoid interference from neighboring electrical appliances that may adversely
influence signal quality and position your Kramer VP-8x8TP away from
moisture, excessive sunlight and dust
to avoid interference, deterioration
in signal quality 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 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 18BShielded Twisted Pair and Unshielded Twisted Pair
We recommend that you use Shielded Twisted Pair (STP) cable. There are
different grades of STP cable available, and we advise you to use the best quality
STP cable that you can afford. Our non-skew-free cable, Kramer BC-STP is
intended for digital signals and for analog signals where skewing is not an issue.
For cases where skewing occurs, our UTP skew-free cable, Kramer BC-XTP, may
be used. Bear in mind, though, that we advise using STP cables where possible,
since the compliance to electromagnetic interference has been tested using STP
cables.
Although Unshielded Twisted Pair (UTP) cable might be preferred for long range
applications, UTP cable should be installed as far as possible from electric cables,
motors, and so on, as these devices tend to create electromagnetic interference.
However, since the use of UTP cable might not conform to electromagnetic
standards, Kramer does not commit to meeting the standard with UTP cable.

3.3 Defining the EDID
The Extended Display Identification Data (EDID1
3.4 The Power Connect™ Feature in the VP-8x8TP
) is a data-structure, provided by
a display, to describe its capabilities to a graphics 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.
The Power Connect feature applies as long as the cable can carry power. This
feature is available when using STP cable and the distance does not exceed 50m
(164ft) on standard CAT 5 cable. For longer distances, heavy gauge cable should
be used (CAT 5 cable is still suitable for the video/audio transmission, but not for
feeding the power at these distances). For units which are connected via RJ-45
connectors, make sure that the shield of the STP cable is connected to the metal
casing of the connectors on both ends of the cable. For units which are connected
via terminal block connectors, the shield of the STP cable must be connected to a
ground terminal on the units at both ends (use the ground terminal of the power
supply connection if necessary).
For a CAT 5 cable exceeding a distance of 50m, separate power supplies should be
connected to the receivers simultaneously.
Note: The transmitter can supply power to the receiver but not visa versa.
