Overview

EXT3-21-XR-TR is a high−performance, extended−reach HDBaseT 3.0 extender for 4K60Hz

(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.

Kramer Electronics Ltd.

EXT3-21-XR-TR – Operating and Controlling EXT3-21-XR-TR

• 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.

Same synched pair operation applies also to mixed pairs of any Tx and Rx 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 Policy on 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 IP-Driven Control Signals via Built-in Control Gateway

• Remote IP connected clients can communicate and control (send commands, and receive responses and notifications), via the LAN, using the EXT3-21-XR-TR built-in and I/O control gateway:

 RS-232 commands, to control devices connected to EXT3-21-XR-TR serial control

ports or HDBT serial channels. The built-in control gateway sends the serial control commands (converted from the client received IP messages) to the serially controlled connected devices and distributes their received responses to all connected clients.

 IR commands, to control devices connected to EXT3-21-XR-TR IR control ports or

HDBT IR channels. The built-in control gateway sends the IR control commands (converted from the client received IP messages) to the IR controlled connected devices.

 Relay commands, to control devices connected to EXT3-21-XR-TR relay control

ports. The built-in control gateway sends the relay control commands (converted from the client received IP messages) to the relay controlled connected devices.

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.

• IR extension (HDBT IR) – From panel IR port or Internal Gateway, via HDBT IR channel, to control a peripheral connected to the HDBT paired device IR port. IR signals sending

method is transparent pass-thru of received IR signal only.

• IR Local (Panel IR) – From HDBT extension or Internal Gateway to Local (Panel) IR port. IR signals sending methods are as follows:

 Pass-thru – Transparent pass-through of received IR signal (default).

 Modulation – IR signal extension with 38KHz modulated IR signal output.

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):
