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/KDS-EN7 or
www.kramerav.com/downloads/KDS-DEC7 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 KDS-EN7 / KDS-DEC7 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.

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 KDS-EN7 4K AVoIP Encoder / KDS-DEC7 4K
AVoIP Decoder. KDS-EN7 / KDS-DEC7 is an advanced encoder/decoder for streaming
4K@60Hz (4:2:0) video signals, USB, IR, RS-232, or CEC signals via Ethernet over copper
cable in unicast (one-to-one) or multicast (one-to-many) configurations.
KDS-EN7 encodes and streams the video signal, and transmits USB, IR, RS-232, or CEC
signals over an IP network. KDS-DEC7 decodes the video signal and receives USB, IR,
RS-232, or CEC signals.
KDS-EN7 and KDS-DEC7 provide exceptional quality, advanced and user-friendly operation,
and flexible control.
Exceptional Quality
•Video Streaming Transmitter/receiver - Streams up to 4K@60Hz (4:2:0) resolution
signals over a 1G network interface.
•HDR Support –HDR10 up to 4K@30Hz 4:2:2 12bits.
•Streaming Support –Provides unicast and multicast streaming.
•Flexible Analog Audio Embedding and De-embedding - Select the balanced analog
audio as input to embed into the streaming and HDMI output signal, or as output to
extract the HDMI audio signal and output it as balanced analog audio.
•Analog Audio De-embedding –KDS-DEC7 extracts the HDMI audio signal or LAN
streaming audio and outputs it as balanced analog audio.
•Video Wall Support –KDS-DEC7 can create a video wall of up to 16x16 displays.
•KVM and OSD Menu Switching - KDS-DEC7 On Screen Display Menu triggered by USB
hotkey for quick switching between different encoders.

pages, Protocol 3000 API commands via Ethernet, or front panel LCD and navigation
buttons.
•PoE Support –Powered with PoE connection from PoE switch.
•Keyboard and Mouse Roaming.
•Control Gateway - Through P3K or special TCP connection, users can
control/communicate with IR, RS-232, or CEC to the connected devices.
•Separate Service LAN Port –can be used for physical separation between AV and
command streams to separate LAN for security and reliability purposes.
Flexible Connectivity
•Analog/embedded audio inputs and outputs.
Typical Applications
KDS-EN7 is ideal for the following typical applications:
•Real-time essential installations such as command and control rooms.
•Large scale AV content sharing installations using existing wires and infrastructure in
corporate offices and government applications.
•AV distribution systems with one or more sources and multiple displays in schools,
universities, and public venues.
•AV installations where low latency KM/KVM capabilities are required.
Controlling your KDS-EN7
Control your KDS-EN7 directly via Navigation buttons, or via:
•The Ethernet using built-in user-friendly web pages.
•Protocol commands.
