(4:4:4) HDMI, USB, Ethernet, PoE power, RS−232, and IR signals over twisted pair, flexibly
set as transmitter−side or receiver−side device.
EXT3-21-XR-TR transmitter−side converts all input signals into the transmitted HDBaseT 3.0
signal and extends uncompressed video signals to up 100m (330ft) over CAT copper cables
at up to 4K@60Hz (4:4:4) video resolution.
EXT3-21-XR-TR receiver−side is an auto−switcher with HDMI and HDBaseT inputs that
receives the HDBaseT 3.0 signal and converts it back into the original input signals. The
connected USB 3.1 peripherals, such as a room camera and microphone, are switchable for
use of the active USB host, for convenient hybrid meeting operation with both room and
online participants.
EXT3-21-XR-TR provides exceptional quality, advanced and user-friendly operation, and
flexible control.

Pair-synched Coupled AV+USB Auto Switching
Two paired EXT3-21-XR-TR devices, one set as a transmitter (Tx mode) and the other set as
a receiver (Rx mode), feature a default inter-synched pairing operation; No additional control
system is needed to synch the pairing operation. This kit-like pair operation provides a costeffective solution for standard rooms with flexible support for both Room-Based Meeting
(RBM) or Bring Your Own Meeting (BYOM) hybrid meeting scenarios, as follows:
RBM scenario:
• Rx-connected room PC/NUC is running the room-based meeting app, such as Zoom
Room.
• The room PC/NUC is auto-connected to all room USB devices, both the Tx-connected
and Rx-connected USB devices.

• Room-located participants use the Tx-connected room USB devices for collaborating
and sharing content via the room PC/NUC.
Figure 4: RBM Scenario
BYOM scenario:
• Room-located hybrid meeting participants bring their portable laptops running their own
meeting app, such as Microsoft Teams.
• When the laptop connects to Tx, the laptop is auto-connected to all room USB devices,
both the Tx-connected and Rx-connected USB devices.

providing that each device supports the pair-synced operation feature
Coupled or Individual AV+USB Switching
When operating EXT3-21-XR-TR as a receiver switcher, multi-signal switching of any of the
inputs to the AV output and connected USB devices, is configurable to use one of the
following operation modes:
• USB follows AV coupled routing () – Selecting an AV input, routes the AV signal to
the AV output and connects, in parallel, the input-associated USB host with the
connected USB devices.
• USB signal individual routing () – Selecting an AV input, routes the AV signal to the
AV output only. The USB host can be independently selected to connect with the
connected USB devices.
This is very useful in hybrid sessions, for convenient switching between multiple presenters
using either their BYOD laptops and/or connected space PC devices.

Set the inputs switching policy to connected output and room devices to:
• Manual – Select an input manually and switching occurs whether input live signals are
present or not.
• Auto – Auto Switching selection is performed in either Last Connected or Priority policy.
In Last Connected policy, if the signal on the current input is lost, EXT3-21-XR-TR
automatically selects the last connected input. The auto-switching delay depends on the
configurable signal-lost timeout.
In Priority policy, when the input sync signal is lost for any reason, the input host with a live
signal and next in priority is selected automatically. The auto-switching delay depends on the
configurable signal-lost timeout. Inputs priority is configurable.
(see Setting the Auto-Switching Policyon page 27).
Online Meeting Systems Integration
USB device ports can be set to auto-disconnect following presenter disconnection, to allow
smooth integration and auto-activation of connected online meeting room systems.
(see Auto-disconnecting a USB Device on Inactive Host on page 37
).

Routing AV and USB Host Signals
EXT3-21-XR-TR enables switching any of the inputs to the output in one of the following
operation modes:
• USB follows AV coupled routing () – Selecting an input, routes the HDMI signal to the
output and associates the USB devices to that selected input USB host.
• USB signal individual routing () – Selecting an input, routes the HDMI signal to the
output. The independently selected USB host, either the local or remote host, is
connected to both local and remote USB device ports.
Independent USB Host Routing
In the following example, USB routing does not follow video, so you can independently select
the AV signal on input 1 and the USB signal on input 2. This means that the HDMI input 2 AV
signal is routed to the AV output and the USB devices are associated with the remote HDBT
USB host.

Protocol 3000
Kramer devices can be operated using Kramer Protocol 3000 commands sent via serial or
Ethernet ports.
Understanding Protocol 3000
Protocol 3000 commands are a sequence of ASCII letters, structured according to the
following.
• Command format:
• Feedback format:
• Command parameters – Multiple parameters must be separated by a comma (,). In
addition, multiple parameters can be grouped as a single parameter using brackets ([
and ]).
•Command chain separator character – Multiple commands can be chained in the
same string. Each command is delimited by a pipe character (|).
•Parameters attributes – Parameters may contain multiple attributes. Attributes are
indicated with pointy brackets (<…>) and must be separated by a period (.).
The command framing varies according to how you interface with EXT3-21-XR-TR. The
following figure displays how the # command is framed using terminal communication
software (such as Hercules):
