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

5 Installing the VP-26 on a Rack
This section describes what to do before installing on a rack and how to rack
mount.
Before Installing in a rack How to Rack Mount
Before installing in a rack, be sure that the environment is
within the recommended range: To rack-mount a machine:
1. Attach both ear brackets to the
machine. To do so, remove the
screws from each side of the
machine (3 on each side), and
replace those screws through the
ear brackets.
2. Place the ears of the machine
against the rack rails, and insert the
proper screws (not provided)
through each of the four holes in the
rack ears.
Note that:
•In some models, the front panel
may feature built-in rack ears
•Detachable rack ears can be
removed for desktop use
•Always mount the machine in the
rack before you attach any cables
or connect the machine to the
power
•If you are using a Kramer rack
adapter kit (for a machine that is not
19"), see the Rack Adapters user
manual for installation instructions
(you can download it at:
http://www.kramerelectronics.com)
Operating temperature range +5°to +45°C (41°to 113°F)
Operating humidity range 10 to 90% RHL, non-condensing
Storage temperature range -20°to +70°C (-4°to 158°F)
Storage humidity range 5 to 95% RHL, non-condensing
!
CAUTION!!
When installing on a 19" rack, avoid hazards by taking
care that:
1. It is located within the recommended environmental
conditions, as the operating ambient temperature of a
closed or multi unit rack assembly may exceed the
room ambient temperature.
2. Once rack mounted, enough air will still flow around
the machine.
3. The machine is placed straight in the correct
horizontal position.
4. You do not overload the circuit(s). When connecting
the machine to the supply circuit, overloading the
circuits might have a detrimental effect on overcurrent
protection and supply wiring. Refer to the appropriate
nameplate ratings for information. For example, for
fuse replacement, see the value printed on the
product label.
5. The machine is earthed (grounded) in a reliable way
and is connected only to an electricity socket with
grounding. Pay particular attention to situations where
electricity is supplied indirectly (when the power cord
is not plugged directly into the socket in the wall), for
example, when using an extension cable or a power
strip, and that you use only the power cord that is
supplied with the machine.

Figure 41).
4. Connect the MASTER OUTPUT LINE terminal block connector, if
required (not shown in Figure 4; see section 7.3).
5. Connect the MASTER OUTPUT SPKR block connector to a pair of
loudspeakers, by connecting the left loudspeaker to the “L+” and the “L-”
terminal block connectors, and the right loudspeaker to the “R+” and the
“R-” terminal block connectors. Do not Ground the loudspeakers.
6. Connect the CAT 5 VGA 2 OUT twisted pair connector (see section 6.3) to
a line receiver (for example, the TP-122 XGA / Audio Line Receiver2,
which is connected to a remote display and speakers).
7. Connect a dynamic or a condenser microphone3, if required, to the MIC IN
XLR connector.
8. You can connect a PC and/or controller to the:
RS-232 port (see section 6.4)
RS-485 port (see section 6.5)

6.5 Connecting via RS-485
You can control a VP-26 unit via an RS-485 controller, or a Master
Programmable Remote Control system such as the Kramer RC-3000.
To connect an RC-3000 to a VP-26 unit (see Figure 10), connect the
RS-485 terminal block port on the RC-3000 to the RS-485 port on the
VP-26 unit, as follows:
•Connect the “A” (+) PIN on the RS-485 rear panel port of the
RC-3000 to the “A” (+) PIN on the RS-485 rear panel port of the
VP-26 unit
•Connect the “B” (-) PIN on the RS-485 rear panel port of the
RC-3000 to the “B” (-) PIN on the RS-485 rear panel port of the
VP-26 unit
•If shielded twisted pair cable is used, the shield may be connected
to the “G” (Ground) PIN on one of the units (for example, on the
RC-3000)
