Overview

Congratulations on purchasing your Kramer VP-427X 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

• 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-427X is ideal for the following typical applications:

• Classrooms and lecture halls

• Meeting rooms

• Training facilities

• Collaborative classrooms

• Any space where BYOD support is required

VP-427X – Upgrading Firmware

20

Upgrading Firmware

Upgrade the firmware in any of the following ways:

• Connecting the device to your PC and using Kramer K-UPLOAD software.

• Via PROG USB port (see USB Firmware Upgrade (USB Format FAT32)

on page 20).

USB Firmware Upgrade (USB Format FAT32)

To update the firmware via PROG USB port:

1. Save VP_427X bin. file (for example, VP_427X_all_V*.bin) in USB flash driver and plug
into PROG USB port.

2. Press and hold MENU+ENTER buttons for about 3 seconds until both HDBT/HDMI
INPUT LEDs blink.

3. Continue holding buttons until both LEDs are lit consistently (this could take up to 60
seconds).

4. Set the unit to factory reset (MENU>FACTORY>RESET ALL).

5. Power off and remove the USB flash driver.

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.
