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.
to www.kramerav.com/downloads/KDS-SW3-EN7 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-SW3-EN7 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.
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

Overview
Congratulations on purchasing your Kramer KDS-SW3-EN7 4K AVoIP Encoder with Dante.
KDS-SW3-EN7 is an auto switcher and advanced encoder for streaming a selected video
signal at 4K@60Hz via Ethernet over copper cable in unicast (one-to-one) or multicast (one-
to-many) configurations. It can add digital audio Dante (AES-67 is not supported), USB, IR,
RS-232, or CEC signals.
KDS-SW3-EN7 encodes and streams the video signal from one of three selectable inputs:
HDMI IN 1, HDMI IN 2 or USB-C input. It transmits de-embedded HDMI audio to digital Dante,
USB, IR, RS-232, or CEC signals over an IP network. The Kramer KDS-SW3-EN7 receives
data traffic from KDS-DEC7 USB devices.
KDS-SW3-EN7 provides exceptional quality, advanced user-friendly operation, and flexible
control.
Exceptional Quality
•Instantaneous Switching Time –1 second switching time between selectable video
inputs.
•Video Streaming Transmitter - Streams up to 4K@60Hz (4:2:0) resolution signals over a
1G network interface. While KDS-DEC7 decodes the stream to 4K@30Hz (4:4:4)
resolution.
•Streaming delay 33msec for video 4K@30Hz 4:4:4 signal.
•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 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.
•Flexible Digital Audio Embedding and De-embedding Dante - Select digital 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.
•Easy To Use KM/KVM Support –Searchable, OSD menu for KM and fully configurable
KVM roaming.
•Power consumption without USB-C Power Delivery is 13W, and power consumption with
USB-C Power Delivery is 77W (requiring the optional power supply).

Advanced and User-friendly Operation
•Convenient and Comprehensive Control –Control the unit using intuitive embedded web
pages, Protocol 3000 API commands via Ethernet, or front panel LCD and navigation
buttons.
•PoE Support –Powered with PoE connection from PoE LAN switch.
•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
•Selectable Inputs –2 HDMI and 1 USB-C input.
•Analog/Digital audio inputs and outputs.
•Plug-and-play with Netgear M4250 AVoIP switches, Kramer Control, and KDS-USB2.
Typical Applications
KDS-SW3-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-SW3-EN7
Control your KDS-SW3-EN7 directly via Navigation buttons, or via:
•The Ethernet using built-in user-friendly web pages.
•Protocol commands.
•KDS-7-MNGR.
