Introduction
Overview
This product is a 3 x 1 auto switching HDBaseT 2.0 transmitter that supports long distance transport of HDMI, USB-C and high-speed USB 2.0 signals up to 40m/131ft using a Cat 5e/6/6a/7 cable. It is 4K compatible with a max resolution of 4K@60Hz/4:2:0 8bit deep color. The PoH feature enables the transmitter to be powered by an HDBT receiver.
The transmitter allows you to automate the display power ON by using pre-loaded RS232 commands whenever a video signal is introduced to the system. It will also turn the display power OFF after a specified amount of time has passed when no video signal is present. It gives you the ability to turn the display ON or OFF as well and switch from one input to another manually using the control buttons on the transmitter panel.
This product is ideal for situations where USB must be extended alongside HDMI for display interactivity for items such as interactive whiteboards or projectors.
Note: The transmitter must be used with an HDBaseT 2.0 receiver (e.g., DSCV-70-RX, sold separately) to complete the extension circuit.

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 an HDBT receiver via a Cat 5e/6/6a/7 cable.
- For additional control option: Connect a control keypad to RS232 of the transmitter.
- Connect an HDMI display and USB devices to the receiver.
- Power on the receiver.
- Connect the video sources and USB host device to the transmitter.
- Select a desired video source through automatic or manual switching function.
Automatic Switching
- The transmitter offers automatic switching function.
- The automatic switching function follows the Last-In-First-Out rule. For example, 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 IN 1 > HDMI IN 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 command through UPDATE port: connect a control PC to the UPDATE port of the transmitter (see the following figure). API command for device control is available in the separate document “API Command Set_EX0101-N008-H20&H21”. 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 and control
PC are configured correctly.
