Introduction

Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world
of unique, creative, and affordable solutions to the vast range of problems that confront the
video, audio, presentation, and broadcasting professional on a daily basis. In recent years, we
have redesigned and upgraded most of our line, making the best even better!

Getting Started

We recommend that you:

• Unpack the equipment carefully and save the original box and packaging materials for
possible future shipment.

• Review the contents of this user manual.

Go to www.kramerav.com/downloads/VP-427X1 to check for up-to-date user manuals,
application programs, and to check if firmware upgrades are available (where appropriate).

Achieving Best Performance

• Use only good quality connection cables (we recommend Kramer high-performance,
high-resolution cables) to avoid interference, deterioration in signal quality due to poor
matching, and elevated noise levels (often associated with low quality cables).

• Do not secure the cables in tight bundles or roll the slack into tight coils.

• Avoid interference from neighboring electrical appliances that may adversely influence

signal quality.

• Position your Kramer VP-427X1 away from moisture, excessive sunlight and dust.

Safety Instructions

Caution:

• This equipment is to be used only inside a building. It may only be connected to other
equipment that is installed inside a building.

• For products with relay terminals and GPI\O ports, please refer to the permitted rating
for an external connection, located next to the terminal or in the User Manual.

• There are no operator serviceable parts inside the unit.

Warning:

• Use only the power cord that is supplied with the unit.

• To ensure continuous risk protection, replace fuses only according to the rating

specified on the product label which is located on the bottom of the unit.

Recycling Kramer Products

The Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC aims to reduce
the amount of WEEE sent for disposal to landfill or incineration by requiring it to be collected
and recycled. To comply with the WEEE Directive, Kramer Electronics has made
arrangements with the European Advanced Recycling Network (EARN) and will cover any
costs of treatment, recycling and recovery of waste Kramer Electronics branded equipment on

arrival at the EARN facility. For details of Kramer’s recycling arrangements in your particular

country go to our recycling pages at www.kramerav.com/il/quality/environment.

Overview

Congratulations on purchasing your Kramer VP-427X1 4K HDBT/HDMI Receiver Scaler

Switcher.
VP-427X is a high−performance auto−switcher receiver with integrated scaler for 4K HDMI™

over long−reach HDBaseT, with a local HDMI input and an HDMI output. VP-427X receives

the HDBaseT signal from a compatible transmitter, converts it to an HDMI signal and up− or
down−scales the picture to any resolution up to 4K@60Hz (4:4:4) set by the user or

automatically matching the resolution of the display connected to the HDMI output.

Exceptional Quality

• Auto Switcher Ease of Use — Automatically plays the switched source signal on the
connected display according to user–configured preferences, such as auto-scan or last–
connected input. When the user manually switches, by pressing a button, the auto
switching is overridden.

• Fast and clean AV Switching — Clean and instantaneous switching between inputs, with
smooth, fade-through-black, uninterrupted transitions between presented content on the
display, greatly enhancing end–users presentation experience.

• High–Performance Scaling Experience — Built–in ProcAmp high–resolution scaling
technology for optimal up or down image scaling and video signal auto–adjustment with
output–connected display capabilities to gain end–users valuable high presentation
experience.

• HDMI Signal Switching — HDCP 2.2 compliant, supporting deep color, x.v.Color™,
CEC, lip sync, HDMI uncompressed audio channels, Dolby TrueHD, DTS–HD, 2K, 4K,
and 3D as specified in HDMI 2.0.

• I–EDIDPro™ Kramer Intelligent EDID Processing™ — Intelligent EDID handling,
processing, locking and pass–through algorithm ensures plug & play operation for HDMI
source and display systems.

Advanced and User-friendly Operation

• Display On/Off Operation — Meeting presentation is simplified by automatically turning
ON/OFF a CEC–enabled display when the presentation source is plugged in /
unplugged.

• Convenient Unit Control and Configuration Options — Local control via front panel

Kramer Electronics Ltd.

source switching buttons and OSD menu. Distance control via RS–232 serial commands
transmitted by a PC, touch screen system or other serial controller.

• Easy, Cost–effective Maintenance — Local firmware upgrade via USB connector.

• Easy and Elegant Installation — Compact MegaTOOLS™ fan–less enclosure for

dropped–ceiling mounting, or side–by–side mounting of 2 units in a 1U rack space with
the recommended rack adapter.

Flexible Connectivity and Control

• Wired and Wireless Auto Switcher — When the receiver is connected to a wireless
connectivity device such as Kramer VIA, can automatically select between a wired
source at the transmitter or the wireless source at the receiver.

• High Performance Standard Extension — Professional HDBaseT extension for providing
long–reach signals over twisted–pair copper infrastructures. VP-427X is a standard
receiver that can be connected to any market–available HDBaseT–compliant extension
product. For optimum extension reach and performance, use recommended Kramer
cables.

• Audio De–embedding — The digital audio signal passing–through to the HDMI output, is
de–embedded, converted to an analog signal and sent to the stereo balanced analog
audio output. This enables playing the audio on a locally connected professional audio
system (such as DSP) and speakers, in parallel to playing it on the speakers connected
to the AV acceptor device (such as TVs with speakers).

• Bidirectional RS–232 Extension — Serial interface data flows in both directions, allowing
data transmission and device control.

Typical Applications

VP-427X1 is ideal for the following typical applications:

• Classrooms and meeting rooms with multiple connections that require automated
switching and automated display control.

• Projection systems in conference rooms, boardrooms, auditoriums, and churches.

• Any application where high quality conversion and switching of multiple and different

video signals to graphical data signals is required for display or projection purposes.

Controlling your VP-427X1

Control your VP-427X1 directly via the front panel push buttons (with on-screen menus, or:

• By RS-232 serial commands transmitted by a touch screen system, PC, or other serial
controller.

• Via the Ethernet using built-in user-friendly web pages.

INPUT LEDs are lit, and then release buttons.
the device enters USB mode and firmware upgrade starts.
Upon completion (after about 30 seconds), the device reboots.

If the device is in USB mode but can’t read the firmware file or if the USB flash driver is not

connected, it reboots automatically after 10 seconds and exits the USB mode.

If the power drops during firmware upgrade, it automatically starts upgrading once the power
is back.

If the power drops in the early stages of firmware upgrade, you need to start firmware
upgrade again.

VP-427X1 – Protocol 3000

50

Protocol 3000

Kramer devices can be operated using Kramer Protocol 3000 commands sent via serial or
Ethernet ports.

Understanding Protocol 3000

Protocol 3000 commands are a sequence of ASCII letters, structured according to the
following.

• Command format:

Prefix

Command Name

Constant (Space)

Parameter(s)

Suffix

#

Command



Parameter

<CR>

• Feedback format:

Prefix

Device ID

Constant

Command Name

nn @ Command

Parameter

<CR><LF>

• Command parameters – Multiple parameters must be separated by a comma (,). In
addition, multiple parameters can be grouped as a single parameter using brackets ([
and ]).

• Command chain separator character – Multiple commands can be chained in the
same string. Each command is delimited by a pipe character (|).

• Parameters attributes – Parameters may contain multiple attributes. Attributes are
indicated with pointy brackets (<…>) and must be separated by a period (.).

The command framing varies according to how you interface with VP-427X1. The following
figure displays how the # command is framed using terminal communication software (such
as Hercules):
