USB-C IN Connector
Connect to a USB-C AV source (that supports DisplayPort Alternate Mode) for AV input,
USB host connection to local and remote connected USB devices (when the device DIPswitch is set to active host as defined in Step 4:Connect inputs and outputs), and LAN
connection. Charges sources (that support USB Power Delivery 2.0) up to 60W when the
device is powered via the power adapter). While charging, the charging icon (to the right of
the connector) becomes visible and lights orange.
Note: active host can be set only on one device, either the transmitter or the receiver, not
both.

ACTIVE HOST LED
Lights orange when the USB host side is active.
4
IN LED
Lights blue when an active AV input signal is detected from the source device connected to
the USB-C.
5
OUT LED
Lights blue when an HDMI output device is detected on the receiver side.
6
LOOP LED
Lights blue an active signal is transmitted on the HDMI LOOP port.
7
LINK LED
Lights green when the HDBT connection is active.
8
ON LED
Lights green when receiving power.
9
HDBT OUT PoE RJ-45
Connector
Connects to the HDBT IN RJ-45 connector on a receiver (for example, EXT3-POE-XR-R).
Receives PoE (PD).
10
HDMI LOOP Connector
Connect to a local acceptor.
11
USB A 2.0 Charging
Connector 1

Host PC is disconnected, the USB signal and charging power for this port are inactive.
12
USB A 2.0 Charging

Connect to the USB local peripheral devices (for example, a USB camera, a soundbar,
microphone and so on). When USB Host PC is disconnected, the USB charging power for
this port continues to be active.
13
IR 3.5mm Mini Jack
Bidirectional IR connection. Outputs a received IR signal (from the HDBT receiver) to
connected IR emitter or transmits an IR signal (from IR sensor) to the HDBT receiver.
14
RS-232 3-pin Terminal Block
Connect to a controller device (for example, SL-240C) to control a remote device via serial
connection (for example, the remotely connected PTZ USB camera).
15
1G LAN RJ-45 Connector
Connect to a LAN for LAN-connection to the source device that is connected to the USB-C
and Ethernet extension to the receiver.
16
SETUP 6-way DIP-switch
Sets the device behavior (see Step 4:Connect inputs and outputs).

Step 3: Mount EXT3-C-XR-T
Install EXT3-C-XR-T using one of the following methods:
• Attach the rubber feet and place the unit on a flat surface.
• Fasten a bracket (included) on each side of the unit and attach it to a flat surface
(see www.kramerav.com/downloads/EXT3-C-XR-T).
• Mount the unit in a rack using the recommended rack adapter
(see www.kramerav.com/product/EXT3-C-XR-T).
• Ensure that the environment (e.g., maximum ambient temperature &
air flow) is compatible for the device.
• Avoid uneven mechanical loading.
• Appropriate consideration of equipment nameplate ratings should be
used for avoiding overloading of the circuits.
• Reliable earthing of rack-mounted equipment should be maintained.
• Maximum mounting height for the device is 2 meters.
Step 4: Connect inputs and outputs
Always switch OFF the power on each device before connecting it to your EXT3-C-XR-T.
