This section describes:
•A summary of the VP-26, see section 3.1
•The power connect feature, see section 3.2
•Using shielded twisted pair (STP)/unshielded twisted pair (UTP), see
section 3.3
•Recommendations for achieving the best performance, see section 3.4
•The terminology used in this user manual, see section 3.5
3.1 About the VP-26
The VP-26 is a high quality one-box presentation matrix switcher, which
includes three independent 4x2 audio/video matrix switchers, one
independent 2x2 audio/video matrix switcher and a master audio switcher.
It combines the functions of a 4x2 matrix switcher for computer graphics
(VGA/UXGA) signals with audio, a 4x2 matrix switcher for composite
video and audio, a 4x2 matrix switcher for s-Video and audio, and a 2x2
matrix switcher for component video (Y, PB/CB,PR/CR) as well as the
master audio switcher that routes one of the pre-selected audio inputs (from
these four switchers) to two separate outputs.
In addition, the VP-26 features:
•A VGA/UXGA video bandwidth of 300MHz to ensure transparent
performance even in the most critical applications, and is HDTV
compatible
•A composite/SDI video bandwidth of 420MHz, an s-Video bandwidth
of 320MHz, a component video bandwidth of 380MHz, and a CAT 5
resolution of up to UXGA
•37 selector buttons, microphone input level control and master audio
level control
•Microphone talk-over mode (the microphone input signal lowers the
line audio output level when the connected microphone detects sound)
•A CAT 5 output, with a transmission range of more than 300 feet (over
100 meters) that transmits the OUT 2 VGA/UXGA video and audio
signals to a remote acceptor via a receiver
•An internal 5-Watt per channel (24kHz, 3dB), stereo power amplifier
for connecting the speakers directly to the machine
•A panel LOCK button to prevent tampering with the front panel
•Previous setup recall via the non-volatile memory after power up
•Changing the audio output levels via RS-232 commands

Control the VP-26 using 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 infrared remote control transmitter
•The ETHERNET
3.2 About the Power Connect™ Feature
The Power Connect feature means that only one unit in a system, the
transmitter or the receiver, needs to be connected to a power source when
the devices are within 150 feet (50 meters) of each other.
The Power Connect feature applies as long as the cable can carry power. The
distance does not exceed 50 meters on standard CAT 5 cable. For longer
distances, heavy-gauge cable should be used1.
For a CAT 5 cable exceeding a distance of 50 meters, separate power supplies
should be connected to the transmitter and to the receiver simultaneously.
3.3 Shielded Twisted Pair (STP) / Unshielded Twisted Pair (UTP)
We recommend that you use shielded twisted pair (STP) cable. There are
different levels 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 there is skewing, 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 was tested using those cables.
Although unshielded twisted pair (UTP) cable might be preferred for long
range applications, the UTP cable should be installed far away from electric
cables, motors and so on, which are prone to create electrical interference.
However, since the use of UTP cable might cause inconformity to
electromagnetic standards, Kramer does not commit to meeting the standard
with UTP cable.
1 CAT 5 cable is still suitable for the video/audio transmission, but not for feeding the power at these distances

3.4 Recommendations for Achieving the Best Performance
To achieve the best performance:
•Use only good quality connection cables1to avoid 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-26 away from moisture, excessive sunlight and dust
3.5 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.
