1 | USB 2 Type A Ports (1 to 3) | Connect to USB local devices (for example, a USB camera, a soundbar, microphone etc.). Ports provide standard USB device charging. |
2 | USB-C Port (4) | Connect to USB local devices (for example, a USB camera, a soundbar, microphone etc.). 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 (for example, remote buttons or sensors), OR • Output-triggered devices (for example, 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 (for example, the connected PTZ USB camera) to be controlled via a controller (for example, SL-240C) which is IP-connected to a paired SWT3-41U-T. |

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).
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 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 EXT3-UE-R.
Wiring the RJ-45 Connectors
This section defines the TP 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 connectorshield.
