Step 3: Mount EXT3-XR-TR
Install EXT3-XR-TR 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 XR TR).
- Mount the unit in a rack using the recommended rack adapter (see www.kramerav.com/product/EXT3 XR TR).
- 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-XR-TR extender.
Wiring the RJ-45 Connectors
This section defines the HDBT pinout, using a straight pin-to-pin cable with RJ-45 connectors.
For HDBT cables, 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 XR TR. Using third-party cables may cause damage!
| EIA /TIA 568B | |
| PIN Wire Color | |
| 1 | Orange / White |
| 2 | Orange |
| 3 | Green / White |
| 4 | Blue |
| 5 | Blue / White |
| 6 | Green |
| 7 | Brown / White |
| 8 | Brown |
Setting the DIP Switches
- All DIP-switches are set to OFF (up) by default
- All changes in DIP-Switches apply immediately, on-the-fly (no need to power cycle the device), except for DIP-switches 1 and 2.
| # | Feature | DIP-switch Settings |  |
| 1 | Device Operation Mode | OFF (up) – Receiver mode is active. ON (down) – Transmitter mode is active. | |
| 2 | Active USB Host port | OFF (up) – Host is active. ON (down) – Host is inactive (active on remote paired device). | |
| 3 | Define IR Pass-through | OFF (up) – Pass-through the IR signal to or from the IR cable. ON (down) – Add IR modulation (38kHz) to the IR output signal (applies only when the IR port is connected to an IR emitter cable). | |
| 4 | Programing RS-232 | Off (up) – Normal operation mode is enabled (FW programming RS-232 is inactive). On (down) – FW programming RS-232 is active. | |
Step 5: Connect power
Connect the power cord to EXT3-XR-TR and plug it into the mains electricity.
Safety Instructions (See www.kramerav.com for updated safety information) Caution:
- For products with relay terminals and GPI\O ports, please refer to the permitted rating for an external connection, located next to the terminal or in the User Manual.
- 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.
Step 6: Operate EXT3-XR-TR
When connecting USB devices to the USB ports, note that
- The recommended connected USB hub capacity is ≤6.
- The maximum connected USB hub capacity is ≤15.
We recommend that you use USB host PC tools, such as USB TreeView tool, to verify connected USB hubs (internal and externals) and endpoints capacity.
