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

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

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

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.

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.

Note: Quality CAT cables are highly recommended, such as Cat6, AWG 23 or better, S/FTP cable. Please check http://www.hdbaset.org/cables to learn HDBaseT recommended cables.

Alias Name

User can modify DaisyNET II name in case of installation issues when multiple DaisyNET II cascaded. click Apply button to save modifications. Note: The Alias name must be 1~20 characters in length, it could be letters, numbers, space, underscore "_"or dash"-".

Daisy-chain Sequence

User can set the daisy-chain quantity in this column. When multiple DaisyNET II cascaded, it’s recommended to input total quantity of devices cascaded in the chain by logging in the WEB GUI of the first device and then click Start Sequence button. When any DaisyNET II is removed or added in cascaded connection, please log in the first device’s WEB GUI in the chain to reconfigure. By that each DaisyNET II could find out its sequence in the daisy-chain automatically, and it’s particularly necessary for Ring-type Connection.

Note: If the Daisy-chain Quantity inputted is more than devices cascaded in the chain, additional devices would be showed in black in Status page.

Daisy-chain Grouping

User can set DaisyNET II working in grouping mode in this column. DaisyNET II offers Daisy-Chain Grouping mode to meet grouping conference, in case multiple conference groups could be set up and worked independently in cascaded connection. By that each group could only have their local sources to be selected or displayed, and can’t be shared to other groups.

Daisy-Chain Grouping is simply activated by Telnet API or clicking the option on the WEB GUI of device, then the video will stop to be outputted to backward devices. After applying, backward devices can not select or display forward sources, neither been selected or displayed by forward devices.

A cascaded chain could support multiple groups. It’s set up in WEB GUI one by one; Telnet API is also provided to set all or each device independently to work in grouping mode, and cancel it.

Network

The DaisyNET II can be controlled over LAN. There are two IP Mode to choose: Static and DHCP. When users choose Static and modify the IP address then click Apply, this window pops:
