Step 1: Check what’s in the box
EXT3-POE-XR-R 4K HDMI/USB Receiver
- 1 Power adapter and cord
- 1 Bracket set
- 4 Rubber feet
- 1 Quick start guide
Step 2: Get to know your EXT3-POE-XR-R
| # | Feature | Function |
| 1 | HOST USB B 2.0 Connector | When the device DIP-switch is set to active host as defined in Step 4:Connect inputs and outputs, connect a USB host (for example, a room PC) to communicate with the USB peripheral devices (for example, a smart board) connected to USB device ports on this device or the connected remote device.
Note that an active host can be set only one device, either the transmitter or the receiver, not both. |
| 2 | ACTIVE HOST LED | Lights orange when the USB host side is active. |
| 3 | IN LED | Lights blue when an active HDMI input signal is detected on HDMI IN. |
| 4 | OUT LED | Lights blue when an output acceptor device is connected. |
| 5 | LINK LED | Lights green when the HDBT active link connection is established. |
| 6 | PoE► LED | Lights green when power-providing over HDBT is active. |
| 7 | ON LED | Lights green when the device receives power. |
| 8 | HDBT IN PoE◄► | Connect to the HDBT connector on a paired PoE-accepting transmitter device (for example, a EXT3-C-XR-T device). |
| 9 | HDMI OUT | Connect to an HDMI acceptor. |
| 10 | USB A 2.0 Charging Connector 1 | Connect to the USB local peripheral devices (for example, a USB PTZ camera). When the USB Host PC is disconnected, the USB signal and charging power for this port are inactive. |
| 11 | USB A 2.0 Charging Connectors 2-3 | Connect to the USB local peripheral devices (for example, a USB camera, a soundbar, a microphone and so on). When the USB Host PC is disconnected, the
USB charging power for this port continues to be active. |
| 12 | ||
| 13 | IR 3.5mm Mini Jack Connector | Bidirectional IR connection. Outputs a received IR signal (from the HDBT transmitter) to connected IR emitter or transmits an IR signal (from IR sensor) to the HDBT transmitter. |
| 14 | RS-232 3-pin Terminal Block | Bidirectional RS-232 connection. Outputs a signal received from 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 LAN for Ethernet extension to the transmitter. |
| 16 | SETUP 4-way DIP-switch | Sets the device behavior (see Step 4:Connect inputs and outputs). |
| 17 | 48V DC | Connect to the power supply. |
Step 3: Mount EXT3-POE-XR-R
Install EXT3-POE-XR-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-POE-XR-R).
- Mount the unit in a rack using the recommended rack adapter (see www.kramerav.com/product/EXT3-POE-XR-R).
- 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-POE-XR-R.
Wiring the RJ-45 Connectors
This section defines the HDBT pinout, using a STRAIGHT pin-to-pin cable with RJ-45 connectors.
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-POE-XR-R. Using third-party cables may cause damage!
DIP-Switch Settings
The DIP-switches are used to set the HDBT range, upgrade the firmware, Determine IR signal pass-through.
All the DIP-switches are set to OFF (up) by default.
A – DIP-switch Settings
| 1A, 2A | HDBT Range Mode | Off | Off | Standard range mode. |
| Off | On | Ultra-long range mode. | ||
| On | Off | TBD | ||
| On | On | TBD |
B – DIP-switch Settings
Changes to DIP-switches 2B and 3B only take effect after power cycling the device.
| DIP # | Feature | DIP-switch Settings |
| 1B | TBD | |
| 2B | Active USB Host | Off (default) – The device is configured as the host for connected USB devices. |
| On – USB are configured as slaves to the remote connection. | ||
| 3B | IR Modulation | Off (default) – IR pass-thru is enabled. |
| On – IR pass-thru is disabled (add a 38KHz modulation to the IR output signal). | ||
| 4B | RS-232 operation Mode | Off (default) – RS-232 FW programming is inactive (Normal operation mode is enabled). |
| On – RS-232 FW programming is active. |
Step 5: Connect power
- Connect the power adaptor to theEXT3-POE-XR-R and the power cord and plug it into the mains electricity. Alternatively, receive PoE via HDBT.
- Safety Instructions (See www.kramerav.com for updated safety information)
Caution: - There are no operator serviceable parts inside the unit.
Warning: - Use only the power cord that is supplied with the unit.
- Disconnect the power and unplug the unit from the wall before installing.
