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.

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
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@30Hz (4:4:4) resolution
signals over a 1G network interface.
•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 grid and/or mosaic 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.
•Supports Grid or Mosaic Video Wall.
•Built–in Resilient Security Features - Preserves the integrity, availability and
confidentiality of the IT network via a highly secured and resilient AVoIP solution.
KDS-EN7 and KDS-DEC7 comply with IT security requirements, including 802.1x and
HTTPS/TLS.
•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 / KDS-DEC7
Control your KDS-EN7 / KDS-DEC7 directly via Navigation buttons, or via:
•The Ethernet using built-in user-friendly web pages.
•Protocol commands.

Connecting KDS-EN7
By-default, the device uses PoE for powering the device. Optionally, you can separately
purchase a power adapter to connect to the product and plug into the mains electricity.
Always switch off the power to each device before connecting it to your KDS-EN7 and
KDS-DEC7. After connecting your devices, connect their power and then switch on the power
to each device.
Figure 3: Connecting the KDS-EN7 to a KDS-DEC7
To connect KDS-EN7 as illustrated in the example in Figure 3:
1. Connect an HDMI source (for example, a server or a media player) to the HDMI IN
connector on the KDS-EN7.
2. Connect a balanced stereo audio source (for example, the server audio connector) to
the AUDIO IN/OUT 5-pin terminal block connector on the KDS-EN7.
