(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)).
- 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

USB devices that are 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.

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

EIA /TIA 568B

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!
