Step 2: Get to know your EXT3-UE-R

The EXT3-UE-R unit features various ports and indicators. From left to right, top row: USB 2 Type A ports (1-3), USB-C Port (4). Bottom row: LINK LED, ON LED, CAT IN PoC RJ-45 Connector, AUDIO OUTPUT 5-pin Terminal Block Connector (L+, L-, G), I/O 2-pin Terminal Block (S1 to S2), RS-232 3-pin Terminal Block (G, Rx, Tx), LAN PoE RJ-45 Connector, and SETUP 2-way DIP-switch.

#	Feature	Function
1	USB 2 Type A Ports (1 to 3)	Connect to USB local devices (e.g., USB camera, soundbar, microphone). Ports provide standard USB device charging.
2	USB-C Port (4)	Connect to USB local devices (e.g., USB camera, soundbar, microphone). Port provides standard USB device charging. Note: Port does not provide Power Delivery 2.0 charging.
3	LINK LED	Flashes blue when a link is established.
4	ON LED	Lights green when locally powered by the power adapter. Lights orange when powered by PoC.
5	CAT IN PoC RJ-45 Connector	Connect to one of the USB CAT OUT PoC ports on the SWT3-41-U-T, OR CAT A or CAT B on the ACC3-12-SP 1:2 CAT Cable Splitter which can be connected to the SWT3-41-U-T.
6	AUDIO OUTPUT 5-pin Terminal Block Connector (L+, L-, G)	Connect to a balanced analog stereo audio line acceptor.
7	I/O 2-pin Terminal Block (S1 to S2)	Connect to input-triggering devices (e.g., remote buttons or sensors), OR output-triggered devices (e.g., remote alarm LED indication). These GPIO ports may be configured via paired SWT3-41-U-T embedded webpages, as digital input or output ports.
8	RS-232 3-pin Terminal Block (G, Rx, Tx)	Connect to an RS-232 controlled device (e.g., the connected PTZ USB camera) to be controlled via a controller (e.g., SL-240C) which is IP-connected to a paired SWT3-41-U-T.
9	LAN PoE RJ-45 Connector	Connect to LAN or to an IP-controlled device (e.g., the connected PTZ USB camera). The device accepts power from the LAN port.
10	SETUP 2-way DIP-switch	Note: All changes in DIP-Switches apply immediately.

DIP-Switch Settings:

#	DIP-switch Name	DIP-switch State	State Description
1	RS-232 MODE	OFF (up) default	Extension mode
		ON (down)	Programming mode
2	For future use	Mandatory OFF (up)

11 12V DC Power Connector: Connect to the power adapter (optional, not included).

Step 3: Mount EXT3-UE-R

Install EXT3-UE-R 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-UE-R).
Mount the unit in a rack using the recommended rack adapter (see www.kramerav.com/product/EXT3-UE-R).

Important Considerations:

? 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-UE-R.

? USB devices connected to the EXT3-UE-R USB ports are powered/charged while connected.
? Only 9600 baud rate is supported for RS-232 communication for both EXT3-UE-R and EXT3-U-R.

The system diagram illustrates various connection scenarios. A Kramer EXT3-UE-R USB Receiver is shown connected to a PC via USB, Ethernet, Audio, and RS-232 ports. It can receive power via PoC from a LAN connection or a separate 12V DC power supply. The EXT3-UE-R can connect to other Kramer devices like the SWT3-41-U-T (4x1 USB Switcher Transmitter) via CAT cable for USB and PoC, and to an ACC3-12-SP CAT Splitter. It also shows connections to peripherals such as a PTZ Camera, Smartboard, Occupancy Detector, Speakers, and Touch TV, controlled by devices like an SL-240C. The diagram highlights the flow of USB, Audio, RS-232, and Ethernet signals between these components.

Wiring the RJ-45 Connectors

This section defines the TP pinout using a straight pin-to-pin cable with RJ-45 connectors.

PIN	Wire Color (EIA/TIA 568B)
1	Orange / White
2	Orange
3	Green / White
4	Blue
5	Blue / White
6	Green
7	Brown / White
8	Brown

? It is recommended that the cable ground shielding be connected/soldered to the connector shield.
? To achieve specified extension distances, use the recommended Kramer cables available at www.kramerav.com/product/EXT3-UE-R. Using third-party cables may cause damage!

Step 5: Connect power

EXT3-UE-R is powered via PoC or an optional PSU.
