Warnings:
! Before wiring, disconnect the power from all devices.
! During wiring, connect and disconnect the cables gently.
Steps for device wiring:!
1. Connect HDBT OUT port of the transmitter to HDBT IN port of the receiver (such as DSCV-
70-RX) via a single Cat 5e/6/6a/7 cable.
Note: Ensure that the Cat x cable length doesn’t exceed the maximum transmission distance
(please refer to “Specification” section to get the maximum transmission distance).
2. Connect an HDMI source to HDMI IN port of transmitter.
3. Connect an HDMI display to HDMI OUT port of receiver.
4. Connect additional functions options.
• USB pass-through: Connect USB host PC to HOST port of the transmitter and connect
USB devices such as keyboard and mouse to USB DEVICE ports of the receiver. The

connected USB devices can be connected to the host PC.
• RS232 pass-through: Set the DIP switch of the transmitter to PASS-THROUGH
position, connect a RS232 enabled device such as a PC to RS232 port of the
transmitter and receiver respectively.
5. Connect the provided DC 12V power adapter to the receiver.
Note: With one-way PoH function supported, the transmitter can be powered by the receiver
with PSE module, no additional power adapter is needed to be connected to the transmitter.

RS232 Pass-Through
RS232 ports can be used for bi-directional RS232 signal pass-through between the transmitter
and receiver. Set the DIP switch of the transmitter to the position of PASS-THROUGH. Connect
RS232 enabled devices (such as PC) to RS232 ports of the transmitter and receiver. Before
executing the API commands through RS232, please ensure RS232 interface of the device and
the connected PC are configured correctly. RS232 default settings are as follows:
Parameters
Value
Baud Rate
115200 bps
Data bits
8 bits
Parity
None
Stop bits
1 bit
Flow control
None
Note: In Pass-through mode, API commands also can be sent to the transmitter from transmitter
side or receiver side to change baud rate, get its firmware version or upgrade its MCU, etc.
(please refer to the separate document “API Command Set DSCV1-70-TX” to get detail
commands information).
