3.1 About the VP-23RC

The VP-23RC is a high quality all-in-one Presentation Switcher and Media/Room
Controller, which lets you control A/V equipment and room items such as window
blinds, room lights, and a projector lift. The VP-23RC includes two major
sections: the Presentation Switcher section and the Media/Room Controller
section, each of which can be operated independently, or in tandem.

3.1.1 Understanding the Presentation Switcher Section

The Presentation Switcher section includes three independent 4x1 audio/video
switchers1, and a master audio switcher2.

The VP-23RC Presentation Switcher section features:

 Three sets of four selector buttons (for composite video and audio, s-Video

and audio, and VGA/UXGA and audio), and four master audio selector
buttons (CV, s-Video, VGA/UXGA and Mic). Each of these 16 selector
buttons lets you select the inputs to switch to the outputs and can be
configured3 to carry out a sequence of up to 15 commands (a macro) so
that when pressing a configured button, the switching action is followed
by a macro sequence

 VGA/UXGA video bandwidth of 350MHz to ensure transparent

performance even in the most critical applications, and is HDTV compatible

 Composite/SDI video bandwidth of 650MHz, an s-Video bandwidth of

385MHz, and a CAT 5 bandwidth of 158MHz

1 A 4x1 switcher for composite video and audio, a 4x1 switcher for s-Video and audio, and a 4x1 switcher for computer
graphics (VGA/UXGA) signals with audio
2 That routes one of the pre-selected audio inputs (from these three switchers) to two separate outputs

Overview

 Digital microphone input level control and digital master audio level

 Microphone talk-over mode1
 A CAT 5 output, with a transmission range of more than 300 feet (over 100

meters) that transmits VGA/UXGA signals2 to a remote acceptor via a
receiver

 An internal 5-Watt per channel (24kHz, 3dB) power amplifier for

connecting the speakers directly to the machine

 A panel LOCK button to prevent tampering with the front panel
 Recall of the previous setup from non-volatile memory
 Audio output level change (via RS-232)

3.1.2 Understanding the Media / Room Controller Section

The Media/Room Controller section controls A/V equipment—especially
projectors and associated equipment3—in media rooms (such as classrooms,
boardrooms, or auditoriums), as well as room functions such as lights, blinds,
a projector lift and/or a screen motor.

The VP-23RC Media/Room Controller section includes:

 Eight configurable buttons to set up any supported commands
 An Ethernet port4 for configuration and control
 Two bidirectional RS-2325 serial ports for universal display (for example,

projectors) and control of the VP-23RC (or other) switcher

 Four relays for the simplified and centralized control of room functions

(such as lights, blinds, screen settings, and so on). The relays have
normally open (NO) and normally closed (NC) contacts

 Three IR control ports
 An IR-learner for the customized remote transmitters, without the need for

an external unit IR remote control

 Macro mode operation, for programming up to 15 commands with the

press of a single button

 Firmware upgrade support

1 The microphone input signal lowers the line audio output level when the connected microphone detects sound
2 Excludes audio
3 Including the A/V equipment connected to the VP-23RC Presentation Switcher section
4 Also for controlling the Presentation Switcher section
5 The RS-232 terminal block port (item 14 in Figure 3) is also used for firmware upgrade

3.1.3 Controlling the VP-23RC

Control the VP-23RC using the front panel buttons, or remotely via:

 RS-2321 serial commands transmitted by a touch screen system, PC, or

other serial controller

 The Kramer Infrared remote control transmitter
 The ETHERNET2

The VP-23RC is dependable, rugged, and fits into two vertical spaces (2U) of
a standard 19” professional rack.

1 The RS-232 port (item 24 in Figure 3) located in the SWITCHER CONTROL area of the rear panel
2 The Ethernet port is located in the CONTROLLER area of the rear panel and is also used for configuration of the
media/room controller section by the system integrator

Overview

3.2 Connecting the VP-23RC Rear Panel

The VP-23RC can be connected in different configurations, integrating the
Presentation Switcher section with the Media/Room Controller section. The

To connect the VP-23RC as illustrated in the block diagram in Figure 1:

 Connect the A/V equipment1 to the Presentation Switcher section (see

section 6)

 Connect the A/V equipment and room items to the Media/Room

Controller section (see section 7)

3.3 Recommendations for Achieving the Best Performance

To achieve the best performance:

 Connect only good quality connection cables, thus avoiding interference,

deterioration in signal quality due to poor matching, and elevated noise­levels (often associated with low quality cables)

 Avoid interference from neighboring electrical appliances and position

your Kramer VP-23RC away from moisture, excessive sunlight and dust



5 Installing the VP-23RC on a Rack

This section describes what to do before installing on a rack and how to rack
mount.

Before Installing on a Rack

Before installing on a rack, be sure that the environment is
within the recommended range:

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

To rack-mount a machine:

1. Attach both ear brackets to the

How to Rack Mount

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.

When installing on a 19" rack, avoid hazards by taking

CAUTION!!

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.

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)
