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-475UX 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-475UX 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 device.
Warning:
•Use only the power cord that is supplied with the device.
•Disconnect the power and unplug the device from the wall before installing.
•Do not open the device. High voltages can cause electrical shock! Servicing by
qualified personnel only.
•To ensure continuous risk protection, replace fuses only according to the rating
specified on the product label which located on the bottom of the device.

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/support/recycling.
Overview
Congratulations on purchasing your Kramer VP-475UX 12G SDI to HDMI Scaler/Converter.
VP-475UX is a high-performance, dual channel scaler and format converter for SDI video
signals of up to 12G data rate. With its integrated dual scaler, it converts the 12G SDI video
signals from its two input channels (with embedded audio) to two 4K@60Hz (4:4:4) HDMI™
outputs, along with de-embedding the audio signals and sending them to the analog audio
output ports.
Exceptional Quality
•High Performance, Scaled Video Conversion –A high performance, low latency video
processing SDI to HDMI converter, with integrated signal resolution scaler, that converts
up to 12G multi-rate SDI signals to HDMI signals, flexibly scaling to a maximum
resolution of 4K@60 (4:4:4) 18G data rate signals, independent per each channel.
•SDI Multi Rate Signals –Auto-adapts from 270Mbps to 12Gbps data rates, accepts SDI,
HD-SDI, 3G HD-SDI, 6G and 12G SDI compliant input signals with video resolutions of
up to 4K@60Hz (4:2:2) 30bpp. Complying with SMPTE 259M (SD-SDI), 292M (HD-SDI),
344M (ED-SDI), 424M (3G HD-SDI), ST-2081 (6G-SDI) and ST-2082 (12G-SDI)
standards, it supports pass-through of standard embedded audio channels with ancillary
ID and metadata information.
•Adaptable HDMI Data Rates –Flexibly scales to a wide variety of HDMI data rates, from
low 480p to as high as 4K@60Hz (4:4:4) video resolution, adapting to any market-
available AV acceptor device, such as displays and projectors.
•Flexible Audio De-embedding –The user selects to de-embed 2 or 4 of the 16 audio
channels embedded within each SDI input signal. The de-embedded audio is then
embedded in the corresponding converted HDMI output signal, and, in parallel, is de-
embedded and sent to a corresponding device audio output port, either as 2-channel
balanced analog or 4-channel AES/EBU-compliant stereo audio signal. This enables
high-quality audio playback by routing the audio to external speakers in parallel to
routing the audio to the local speakers found on the connected AV acceptor device (such
as a TV or laptop).
•Extended-Reach Input Extension –Input signal equalization and output signals reclocking
to gain extended-reach signal extension. Using high-quality coaxial SDI cables, supports
extension of up to 500m (1640ft) for SD signals; 260m (850ft) for 1.5G HD signals; 220m
(720ft) for 3G; 100m (330ft) for 6G HD signals; 70m (230ft) for 12G 4K signals.

For optimal performance, Kramer recommends using Kramer high-performance cables.
Reach extension performance may vary while using coaxial cables that are not high-quality.
Advanced and User-friendly Operation
•Cost-Effective Maintenance –Indicators for SDI input signals status and data rate, and
power status, for easy local maintenance and troubleshooting. Remote device
management via built-in web UI. Local and remote firmware upgrade via mini-USB or
Ethernet connection ensure lasting, field-proven deployment.
Flexible Connectivity
•Reliable Wire Connectivity –Coaxial broadcast-grade cables are reliably connected via
lockable BNC connectors, preventing unintentional wire disconnections, to gain fast and
highly professional uncompressed SDI signals distribution deployments.
•Easy Installation –19” enclosure for rack mounting a device in a 1U rack space with
included rack ears and universal 100-240V AC power connection.
Typical Applications
VP-475UX is ideal for the following typical applications:
•SDI video production studios.
•Broadcast studio and field SDI video production events.
•Easy integration of SDI cameras and sources to HDMI-based system in any Pro-AV
application.
•Staging and rental deployments.
•Medical facilities with highly reliable video deployments.
Controlling your VP-475UX
Control your VP-475UX via:
•Embedded web pages via a browsing device that is connected to LAN (see Using the
Embedded Web Pages on page 7).
•USB serial port, by Protocol 3000 serial commands transmitted by a computer
(see Protocol 3000 on page 21).
