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/WP-SW2-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 WP-SW2-EN7 away from moisture, excessive sunlight and dust.
Safety Instructions

•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

Overview
Congratulations on purchasing your Kramer WP-SW2-EN7 4K AVoIP Encoder. WP-SW2-
EN7 is an auto switcher and advanced encoder for streaming 4K@60Hz (4:2:0) a selected
video signal, RS-232, or CEC signals via Ethernet over copper cable in unicast (one-to-one)
or multicast (one-to-many) configurations.
WP-SW2-EN7 encodes and streams the video signal from one of two selectable inputs, and
transmits USB, RS-232, or CEC signals over an IP network. The Kramer WP-DEC7 decodes
the video signal and receives USB, RS-232, or CEC signals.
WP-SW2-EN7 provides exceptional quality, advanced and user-friendly operation, and
flexible control.
Exceptional Quality
•Instantaneous Switching Time –1 second switching time between video inputs.
•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.
•Supports HDCP 2.2.
•Streaming Support –Provides unicast and multicast streaming.
•Flexible Analog Audio Embedding –Embed analog audio into the streaming audio signal
and HDMI output, using the unbalanced 3.5mm stereo connector.
Advanced and User-friendly Operation
•Convenient and Comprehensive Control –Control the unit using intuitive embedded web
pages, Protocol 3000 API commands via Ethernet, or the front panel channel display
and recessed navigation buttons (on the US model access to the recessed buttons
requires removal of the frame).
•PoE Support –Device power is supplied by a PoE (Power over Ethernet) connection
from a PoE LAN switch.
•Control Gateway –Users can control/communicate with connected devices using P3K
commands, a TCP connection with RS-232 or CECs.
•Separate Service LAN Port –A second LAN port is available for physical separation

Connecting WP-SW2-EN7
By-default, this device uses PoE (Power over Ethernet) 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 a device before connecting it to your WP-SW2-EN7. After
connecting your devices, connect their power and then switch on the power to each device.
In this example, WP-SW2-EN7 is connected to WP-DEC7, but it can be connected to any
compatible decoder.
Figure 2: Connecting the WP-SW2-EN7 and WP-DEC7
To connect WP-SW2-EN7 as illustrated in the example in Figure 2:
1. Either connect an HDMI source (for example, a server or a media player) to the HDMI IN
connector on the WP-SW2-EN7, or connect a video source (for example, a laptop) to
the USB IN connector on the WP-SW2-EN7.
2. Connect a stereo audio source (for example, the server audio connector) to the AUDIO
IN connector on the WP-SW2-EN7.
3. Connect the LAN MEDIA 1G(PoE) RJ-45 port on the WP-SW2-EN7 to a LAN switch
with PoE and connect the LAN MEDIA 1G(PoE) RJ-45 port on the Kramer WP-DEC7
decoder to the same LAN switch.

4. Connect the HDMI OUT connector on the WP-DEC7 to an HDMI acceptor (for example,
a display).
5. On WP-DEC7, connect a mouse and a keyboard to the two USB type A ports.
6. Connect RS-232 3-pin terminal block connectors:
▪On the WP-SW2-EN7, connect the RS-232 port to a laptop/controller.
▪On the WP-DEC7, connect RS-232 to the display.
RS-232 bidirectional signals can be sent between the display and the laptop
connected to the HDMI OUT connector on the WP-DEC7.
Connecting to WP-SW2-EN7 via RS-232
You can connect to WP-SW2-EN7 via an RS-232 connection using, for example, a PC.
WP-SW2-EN7 features an RS-232 3-pin terminal block connector allowing the RS-232 to
control WP-SW2-EN7.
Connect the RS-232 terminal block on the rear panel of WP-SW2-EN7 to a PC/controller, as
follows:
From the RS-232 9-pin D-sub serial port, connect:
•Pin 2 to the TX pin on the WP-SW2-EN7 RS-232 terminal block
•Pin 3 to the RX pin on the WP-SW2-EN7 RS-232 terminal block
•Pin 5 to the G pin on the WP-SW2-EN7 RS-232 terminal block
