Installation and Wiring

Installation

Note:

Before installation, ensure the device is disconnected from the power source.
The height of installation should not exceed 2 meters from the ground.

Steps to install the receiver in a suitable location:

Attach the installation bracket to the enclosure using the screws provided in the package separately.
The bracket is attached to the enclosure as shown.
Repeat steps 1-2 for the other side of the unit.
Attach the brackets to the surface you want to hold the unit against using the screws (provided by others).

Wiring

Warnings:

Before wiring, disconnect the power from all devices.
During wiring, connect and disconnect the cables gently.

Steps for device wiring:

Connect HDBT Connect HDBT OUT of the transmitter to HDBT IN of the receiver via a Cat 5e/6/7 cable.
Connect an HDMI display and audio receivers (e.g. earphone, speaker) respectively to the receiver.
Connect the provided power adapter to the receiver. With PoH support, it is able to send power to the transmitter; no additional power adapter is required at the transmitter.
Connect the video sources to the transmitter.
Select a desired video source through automatic or manual switching function.
Connect for KVM control: Connect a host PC to USB-B port of the transmitter, and USB devices (e.g. USB camera, keyboard, and mouse) to USB DEVICE ports of the receiver to realize remote KVM control.
Connect for additional control option: Device Control: Connect a control PC to Micro USB port of the transmitter or to RS232 port of the receiver to control the transmitter via API commands. For more information, see Device Control section.

Automatic Switching

The transmitter offers automatic switching function.

The automatic switching function follows the Last-In-First-Out rule. Forexample, if a new active source is connected, the transmitter will automatically switch to this source. If the source selected is removed, the transmitter will automatically switch to the source with top priority (default priority: USB-C > HDMI 1 > HDMI 2).

If you want the display to play video from a specific video source:

Disconnect the cable from your desired video source, and then connect it again.
Use the Input Selection button on the front panel or API commands to select your desired video source.

Note: The automatic switching function can detect the input signal with 5V only. If the selected source in standby mode provides a continuous 5V power output, this function will not work, i.e. the transmitter will not switch the input to other active sources. In this case, please turn off the selected source in standby mode or remove it from the transmitter.

Device Control

Advanced users can control the transmitter via API commands through UPDATE port on transmitter or RS232 port on receiver: connect a control PC or control system to the UPDATE port of the transmitter (see Figure 1) or the RS232 port of the receiver (see Figure 2). API command for device control is available in the separate document. A professional RS232 serial interface software (e.g. Serial Assist) may be needed as well.

Before sending the API command to control the transmitter, ensure the transmitter, control PC and/or receiver are configured correctly.
