display that is connected to the receiver side. Button LED lights blue when remote display power is on.
2| USB-C IN Connector| Connect to a USB-C AV source (that supports DisplayPort Alternate Mode) for AV input, USB host connection to local and remote connected USB devices (when the device DIP- switch is set to active host as defined in Step 4:Connect inputs and outputs), and LAN connection. Charges sources (that support USB Power Delivery 2.0) up to 60W when the device is powered via the power adapter). While charging, the charging icon (to the right of the connector) becomes visible and lights orange.

Note: active host can be set only on one device, either the transmitter or the receiver, not both.

3| ACTIVE HOST LED| Lights orange when the USB host side is active.
4| IN LED| Lights blue when an active AV input signal is detected from the source device connected to the USB-C.
5| OUT LED| Lights blue when an HDMI output device is detected on the receiver side.
6| LOOP LED| Lights blue an active signal is transmitted on the HDMI LOOP port.
7| LINK LED| Lights green when the HDBT connection is active.
8| ON LED| Lights green when receiving power.
9| HDBT OUT PoE RJ-45

Connector

| Connects to the HDBT IN RJ-45 connector on a receiver (for example, EXT3 -POE-XR-R ). Receives PoE (PD).
10| HDMI LOOP Connector| Connect to a local acceptor.
11| USB A 2.0 Charging Connector 1| Connect to the USB local peripheral devices (for example, a USB PTZ camera). When USB Host PC is disconnected, the USB signal and charging power for this port are inactive.
12| USB A 2.0 Charging Connector 2| Connect to the USB local peripheral devices (for example, a USB camera, a soundbar, microphone and so on). When USB Host PC is disconnected, the USB charging power for this port continues to be active.
13| IR 3.5mm Mini Jack| Bidirectional IR connection. Outputs a received IR signal (from the HDBT receiver) to connected IR emitter or transmits an IR signal (from IR sensor) to the HDBT receiver.
14| RS-232 3-pin Terminal Block| Connect to 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 a LAN for LAN-connection to the source device that is connected to the USB-C and Ethernet extension to the receiver.
16| SETUP 6-way DIP-switch| Sets the device behavior (see Step 4:Connect inputs and outputs).
17| 20V DC| +20V DC 6A connector for powering the unit and charging the connected input device to USB-C.
