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/DIP-20 to check for up-to-date user manuals,
application programs, and to check if firmware upgrades are available (where appropriate).
Achieving the 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 DIP-20 away from moisture, excessive sunlight and dust.
This equipment is to be used only inside a building. It may only be connected to other
equipment that is installed inside a building.
Safety Instructions
Caution: There are no operator serviceable parts inside the unit.
Warning: Use only the power cord that is supplied with the unit.
Warning: Do not open the unit. High voltages can cause electrical shock! Servicing by
qualified personnel only.
Warning: Disconnect the power and unplug the unit from the wall before installing.
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

Overview
Congratulations on purchasing your Kramer DIP-20 Automatic Video Switcher which are part of the
Kramer Audio Distribution System and are ideal for:
•Display systems requiring simple, automatic input selection.
•Multimedia and presentation source selection.
•Video distribution in hotel rooms and schools.
The DIP-20 is a 4K UHD, HDBaseT transmitter and Step−in commander for computer
graphics video, HDMI, unbalanced stereo audio signals embedding and de−embedding. The
DIP-20 accepts HDMI and PC graphics video input, an Ethernet signal, serial data, and an
unbalanced stereo audio input (that is embedded into the output signal). It transmits the signal
via HDBaseT (twisted pair) cable to a compatible receiver (for example, the TP−588D,
TP−580RXR or TP-780RXR).
The DIP-20 is a PoE (Power over Ethernet) provider and can power compatible PoE
acceptors (for example, the TP−588D or TP-780RXR). It supports resolutions of up to 4K@60
UHD (4:2:0).
The DIP-20 provides a range of up to 130m (427ft) in normal mode for 1080p@60Hz
@36bpp, and 100m (328ft) for 4K @30Hz.
When using an extended range receiver and BC-UNIKAT cables, the range is up to 180m
(590ft) for 1080p@60Hz @24bpp. To use the DIP-20 in extended range mode you must edit
the EDID.
For optimum range and performance, use recommended Kramer cables available at
www.kramerav.com/product/DIP-20. Note that the transmission range depends on the signal
resolution, graphics card and display used. The distance using non-Kramer CAT 6 and CAT 7
cables may not reach these ranges.
The DIP-20 Automatic Video Switcher features:
•Support for 4K UHD (data rate of up to 10.2Gbps).
•Automatic live input detection based on video clock presence.
•Automatic input selection based on priority selection or last connected input.
•Manual input selection.
•Automatic analog audio detection and embedding.
•Power over Ethernet that passes electrical power along with data over Ethernet cabling.
This allows a single cable to provide both data connection and electrical power to
compatible devices.
•Control via Kramer Protocol 3000 and embedded Web pages over a LAN.
•HDTV support.
•HDMI with Deep Color, x.v.Color™ and 3D.
•HDCP compliancy—works with sources that support HDCP repeater mode.

About HDBaseT™ Technology
HDBaseT™ is an advanced, all-in-one connectivity technology (supported by the HDBaseT
Alliance). It is particularly suitable in the ProAV –and also the home –environment as a
digital networking alternative, where it enables you to replace numerous cables and
connectors by a single LAN cable used to transmit, for example, uncompressed, full
high-definition video, audio, IR, as well as various control signals.
The products described in this user manual are HDBaseT certified.

Connecting the DIP-20 Automatic
Video Switcher
Always switch off the power to each device before connecting it to your DIP-20. After
connecting your DIP-20, connect the power to each of them and then switch on the power
to each device.
Figure 3: Connecting the DIP-20
You do not have to connect all the inputs and outputs, connect only those that are required.
