Introduction
Overview
DaisyNET II is a 100m 4K Daisy-chain Presenter with HDBaseT in
and HDBaseT out, and utilizes HDBaseT technology as
daisy-chain medium to cascade multiple A/V sources, displays or
any devices with HDBaseT connection together in a chain to set
up an A/V distribution system.
DaisyNET II supports three video inputs including HDMI, Display
Port and VGA plus 3.5mm audio in, with HDBaseT input and
HDBaseT output for cascading. A local HDMI out with audio
de-embedder is provided in the rear side to connect local monitor
or zone displays. It has a 2-Port Ethernet Switch built-in so that
Ethernet could pass through over HDBaseT for LAN control, or to
feed LAN access to sources or displays. RS232 port is used to
pass through RS232 commands or control display device. USB
charger is also provided to charge mobile devices. It offers
ShowME button and Contact Closure to switch sources, and
rotary switch for EDID management.
DaisyNET II offers a future-ready Ultra HD A/V switching and
distribution solution, and cutting-edge HDMI 2.0 and HDCP 2.2
compatibility. With user-friendly WEB GUI and Telnet API to
configure advanced functionality including CEC controller, RS232
controller and Daisy-chain Grouping, it is perfectly suitable for
collaboration or presentation in conference and education
application.

Quick Start
DaisyNET II could be used flexibly as either transmitter or receiver
to support a couple of different installations and applications,
because of a local HDMI Out port built in.
Application 1: Chain-type Connection
In Application 1, Device 1 and Device 2 are used as transmitter to
connect source, while Device M and Device Z are dedicated
receivers to connect multiple displays.
Application 2: Chain-type Connection with Local Monitor
In Application 2, each DaisyNET II in the chain has their local
HDMI Out connected with local monitor, so as to show forward or
local source once it’s selected in the chain. Please note only

15
backward devices could display forward sources, while forward
devices can not have their local monitor to show backward
sources.
Application 3: Ring-type Connection
In Application 3, the last Device Z has its HDBT OUT connecting
to HDBT IN of the first Device 1. As a result, each source
selected could be displayed by any monitor in the chain, and fix
the issue in chain-type connection that backward sources can not
be displayed in forward monitors.
Application 4: Grouping Mode
In Application 3, Device 1 and Device 2 work in Group 1, while
Device M and Device Z work in separate Group Z. Devices in
different groups can not select or display sources from other

16
groups. Grouping mode is simply activated by Telnet API or
clicking the Daisy-chain Grouping option on the WEB GUI of
device, then the video will stop to be outputted to backward
devices.
For example, set Device 2 in grouping mode to make Device 1
and Device 2 work as Group 1, then Device 3 and all backward
devices are in the other group; set Device 2 and Device 4 in
grouping mode to make Device 1 and Device 2 in a group, Device
3 and Device 4 work in a group, Device 5 and backward devices in
the other group (More details please check Page 23.) Both
Chain-type and Ring-type connection could support grouping
mode.
Before set up, please take care of below steps:
1. Connect a PC to each device by Ethernet port, log in their WEB
GUI to set static IP address and alias name for every device.
(Please check Page 18 to learn how to log in WEB GUI.)
2. Connect all devices by HDBaseT ports through Cat cable, make
a Chain-type connection firstly and feed LAN access to Ethernet
port of any device. Do not make Ring-type connection directly with
LAN access, otherwise there will be LAN conflicts and LAN control
disabled.
3. Log in WEB GUI of the first device in the chain, input total
quantity of devices cascaded within Daisy-chain Sequence and
then click Start Sequence. (More details please check Page 22
Daisy-Chain Sequence).
4. Connect the HDBT OUT of the last device to the HDBT IN of the

17
first device, log in WEB GUI of the first device to click Start
Sequence again, then Ring-type connection is set up correctly.
Any DaisyNET II reset, removed, replaced or newly added in the
chain, please follow above instruction to configure them again.

18
Connections and Installation
1. Connect the HDBT OUT port of DaisyNET II 1 to the HDBT IN
port of DaisyNET II 2, connect the HDBT OUT port of
DaisyNET II 2 to the HDBT IN port of DaisyNET II 3, and
follow to daisy-chain multiple DaisyNET II through HDBT
ports by Cat cable.
2. Using quality HDMI/DP/VGA cables to connect different
sources (such as Laptop, PC, Blu-ray, satellite/cable TV, etc.)
to HDMI IN/DP IN/VGA IN port of DaisyNET II.
3. Using quality HDMI cables to connect the HDMI display
device (such as Projector, Monitor or TV) to the HDMI OUT of
DaisyNET II.
4. Connect a controller such as IP-based touch panel to an
Ethernet port of DaisyNET II, or Contact Closure-based
keypad to the ShowME/KEY/LED ports to control. Circuit
diagram of Contact Closure ports including SHOW ME, KEY
and LED without any resistors as shown:
Specs of the LED:
2.5 - 3.3 V / 5 - 8 mA
5. Power on all devices. Use the ShowMe button, Contact
Closure, WEB GUI or Telnet API command to operate the
DaisyNET II.
