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.

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 DSCV2-70-TX-UK”. 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.
