3 Overview

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, P

B/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

KRAMER: SIMPLE CREATIVE TECHNOLOGY

Overview

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 shoul d be used

1

.

For a CAT 5 cable exceeding a distance of 50 meters, separate power supplies
should be connected to the transmitter and to the receiver simult aneously.

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 m ight 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

Your Presentation Matrix Switcher

3.4 Recommendations for Achieving the Best Performance

To achieve the best performance:

• Use only good quality connection cables

1

to 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 wi th the machin e.

• Front panel buttons (see section 7.1

)

• Independent switchers AFV mode (see section 7.2

)

• Master audio breakaway mode (see section 7.3

)

7.1 The Front Panel Buttons

Th

e front panel buttons include:

• Two sets of four (from 1 to 4) VGA/UXGA-AUDIO SELECTOR

buttons for switching to OUT 1 and/or OUT 2

• Two sets of four (from 1 to 4) VIDEO (CV)-AUDIO SELECTOR

buttons for switching OUT 1 and/or OUT 2

• Two sets of four (from 1 to 4)

S-VIDEO (Y/C)-AUDIO

SELECTOR buttons for switching to OUT 1 and/or OUT 2

• Two sets of two (1 and 2) COMP-AUDIO SELECTOR buttons for

switching to OUT 1 and/or OUT 2

• Nine MASTER AUDIO SELECTOR buttons (two sets of

VGA/UXGA, CV,

S-VIDEO and COMP for OUT 1 and OUT 2

signals, and MIC)

• MIC AUDIO LEVEL up and down buttons to adjust the level at

the master audio out

1

connectors2 and the talk-over function

3 Achieving optimum results for a particular environment when using a microphone ma y require experi mentatio n in adjusti n g
the AUDIO and MIC LEVELS
4 Two channels are active in the Talk Over mode, a source selected via the MASTER AUDIO SELECTOR buttons and the
microphone channel
5 Adjust the microphone level via the MIC AUDIO LEVEL + and - buttons

Operating Your Switcher

23

By default1, the stereo audio signals switch together with the video, that is, the

unit is set in an AFV 2 mode. You can change to breakaway mode3, via RS-232

Pressing an illuminated AUDIO SELECTOR button for more than 2
seconds mutes the master audio output, and the button no longer
illuminates. The video will continue to display but without sound.

7.2 The Independent Switchers AFV Mode

In th

e independent switchers AFV mode, the four matrix switchers of the

VP-26 operate independently of each other. For each matrix switcher, you
can select any input to switch to the outputs, as illustrated in Figure 15

.

The audio input signal follows the video signal and the last audio signal
selected is outputted to the master audio output

You can route any combination of:

• Two of the four VGA/UXGA inputs to the VGA/UXGA

4

outputs

• Two of the four CV inputs to the CV outputs

• Two of the four Y/C inputs to the Y/C outputs

• The COMP inputs to the COMP outputs

For example

5

, in the CV matrix switcher section, you can switch IN 1 to
OUT 1 and IN 4 to OUT 2 by pressing the VIDEO (CV)-AUDIO
SELECTOR button 1 on the OUT 1 set, and button 4 on the OUT 2 set.

The same applies to the other matrix switcher sections (CV, Y/C and
COMP).

Each pressed button illuminates

6

, indicating selection and outputting of that

video and audio source.

You can choose not to use one or more of the matrix switchers

1 This is, the pre-installed factory default. The default can be modified via the Windows®-based Kramer control software
2 Audio-Follow-Video, in which all operations relate to both the video and the audio channels
3 In which video and audio channels switch independently
4 The OUT 2 signal is also routed to the CAT5 VGA 2 OUT connector
5 Assuming that all inputs are connected
6 Pressing an illuminated button for more than 2 seconds will disconnect the output and the button will no longer illuminate

(for example,

COMP OUT 1 in Figure 15

), regardless of the switcher group (VGA, s-Video,

composite video or component video), and the respective button

2

under the
MASTER AUDIO SELECTOR section illuminates, indicating that the selected
input (for example, COMP OUT 1 in Figure 15

) is routed to the master outputs.

In the Master Audio Breaka way mode

3

, switching a video input will not switch
the respective audio si gnal. You ca n indepe ndently ro ute an au dio input si gnal
from any of the A/V matrix switchers or from the microph one, to the MASTER
OUTPUT LINE

4

and/or SPKR4 outputs, regardl ess of the vide o input l ast
selected. You can change the audio input switched to the master output by
pressing the relevant button under the MASTER AUDIO SELECTOR
section

5

. For example, press the CV OUT 2 button under the MASTER
AUDIO SELECTOR section to route the composite video input 4 signal to
the MASTER OUTPUT, as illustrated in Figure 16

:

Figure 16: Switching in the Master Audio Mode

When a microphone is connected to the MIC IN XLR connector, you can
press the MIC button under the MASTER AUDIO SELECTOR section.
The MIC button illuminates (see Figure 17

) and the speakers output the

MIC IN

6

audio signal, while retaining the current video display. You can
return to the composite video (CV) audio output by pressing the relevant
CV button under the MASTER AUDIO SELECTOR section once again.

This bit is always low, when sending from the PC to the switchers, and high for information sent to the PC.
N5…N0 – “INSTRUCTION”.
These 6 bits define the function that is to be perf orme d by the switcher(s). Similarly, if a function is performed via the
machine’s keyboard, then these bits are set with the INST RUCTION NO, which was performed. The instruction codes ar e
defined according to the table below (INSTRUCTION NO. is the value to be set for N5…N0).
2nd BYTE: Bit 7 – Defined as 1.
Bits 3 – 6 - Defined as 0.
I2… I0 – “INPUT”.
For disconnect, set as 0. For other operations, these bits are defined according to Table 18

.
3rd BYTE: Bit 7 – defined as 1.
Bits 2-6 defined as 0.
O1, O0 – “OUTPUT”
For operations, these bits are defined according to Table 18

.
4th BYTE: Bit 7 – Defined as 1.

NOTES on to Table 18

:

NOTE 1

When the master switcher is reset, (e.g. when it is turned on), the reset code is sent to the PC. If this code is sent to the
switchers, it will reset according to the present power-down settings.

NOTE 2

These are bi-directional definitions. That is, if the switcher receives the code, it will perform the instruction; and if the
instruction is performed (due to a keystroke operation on the front panel), then these codes are sent. For example, if:
0000 0001 Instruction “Switch Groups”
1000 0010 Input #2
1000 1001 in composite video group
1000 0001 Machine #1 (master)
Was sent from the PC, then the switcher (machine #1) will switch input 2 in composite video group to its output. If the user
switched input 4 in the VGA group via the front panel keypad, then the switcher will send:
0100 0001
1000 0100
1000 0011
1000 0001 to the PC.
When the PC sends instruction #1 or #2 to the switch er, then, if the instruction is valid, the switch er replies by sending the
same four bytes to the PC that were sent (except for the first byte, where the DESTINATION bit is set high).

NOTE 3

The reply to a “REQUEST” instruction is as follows: the same instruction and input codes as were sent are returned, and the
OUTPUT is assigned to the value of the requested parameter. The repl y to the instruction #5 (what is the status of the VGA
group?):
0000 0101
1000 0000
1000 0011
1000 0001
Would be:
0100 0101
1000 0000
1000 0100
1000 0001

NOTE 4

An error code is returned to the PC if an invalid code was sent to the switcher (for example, when trying to switch an input or
a group which is greater than the highest one defined). This code is also returned to the PC if an RS-232 instruction is sent
while the machine is being programmed via the front panel. Reception of this code by the switcher will not be valid.

NOTE 5

Under normal conditions, the machine’s present status is saved each time a change is made. The power-down save (the auto
save) may be disabled using this code. Note that each time that the machine is turned ON, the auto save function is
automatically set.

NOTE 6

This is a request to identify the switchers in a system. If the INPUT is set as 1 or 2, the machine will send its na me. The reply
is the decimal value of the INPUT and the OUTPUT. For example, the reply to the request to send the machine’s name (for
machine #001) will be:
0111 1101
1000 0000 (i.e. 128+0)
1001 0111 (i.e. 128+23)
1000 0001
If the request for identification is sent with the INPU T set as 3 or 4, the appropriate mac hine will send its software version
number. Again, the reply would be the decimal value of the INPUT and OUTPUT - the INPUT repre senting the number in
front of the decimal point, and the OUTPUT representing the number following the decimal point. For example, for version

3.5 the reply will be:
0111 1101
1000 0011 (i.e. 128+3)
1000 0101 (i.e. 128+5)
1000 0001

NOTE 7

GAIN VALUE – Number from 0 to 127

NOTE 8

Answer = Current Audio Gain (0 –127)
