3. G4K Pro management software
There are three main groups of tools in this software to help users design a creative video wall layout.
Device, Output and Input
3.1. Device
Users are able to configure G4K Pro devices and connect the devices to control PC in this section.
3.1.1. Connect singe G4K Pro
The default IP address of G4K Pro is 192.168.1.25. Users need to change the IP address of
control PC to the same IP group of G4K Pro.
•Open the ‘Ethernet Properties’ windows on Control PC
•Highlight the TCP/IPv4 in Networking and click the Properties button to open the TCP/IPv4
Properties window
•Change the ‘Obtain an IP address automatically’ to ‘Use the following IP address to set up
a static IP address
➢IP address: any address between 192.168.1.1 and 192.168.1.255 except the
address which has been taken by the G4K Pro
➢Subnet mask: 255.255.255.0
➢Default Gateway: 192.168.1.1

G4K Pro User Guide
•Once the control PC IP address
having been set up, press the Connect
button to connect the G4K Pro.
•The Connect button changes to
Disconnect button indicating the
connection has been set up successfully.
•If a dialog window as below comes
up, the connection was failed.
➢Please check if control PC IP address
is correctly set up
➢Please check the network cable
connection between PC and G4K Pro.

G4K Pro User Guide
3.1.2. Connect multiple G4K Pro as daisy chain
3.1.2.1. Set Up unique IP address for each G4K Pro
Since the default IP address of each G4K Pro is the same, users need to change the IP addresses
of these devices to avoid IP conflict.
1) Users need to connect the G4K Pro one by one using
default IP address: 192.168.1.25 to set up the connection
between device and control PC.
2) Make sure the device has been connected and then
right click the Device Name and then choose Change
Device IP Address to open the ‘Change Device IP Address’
dialog window.
3) Please give a unique IP address for each device in the same system.
e.g.
Device 1 192.168.1.25
Device 2 192.168.1.26
Device 3 192.168.1.27
Device 4 192.168.1.28
3.1.2.2. Daisy chain units with CAT cables
Daisy chain all the units via dual RJ45 ports and connect to the control PC for command and control.

G4K Pro User Guide
3.1.2.3. Daisy chain units with HDMI cables
Daisy chain all the G4K Pro units using 4K compatible HDMI cable (if 4K video source is applied) via
LOOP IN and OUT HDMI ports
Note: the daisy chain HDMI ports only takes the
‘processed video source’ + ‘frame lock’ signals
from other G4K Pro. It will not take HDMI video
signal from video device directly. Only the main
HDMI IN port in the front panel is able to take
HDMI video signal from video device directly.
This configuration left is an example for setting up
a 4 units of G4K Pro daisy chain (e.g. for a 4 x 4
video wall) with one video source input to be
displayed across the entire video wall.
For multi video sources input, please see daisy
chain examples below (3.1.2.6)
3.1.2.4. Connect devices to screens
Connect all the HDMI ports in ‘HDMI OUT’ to the screens of video wall. e.g., for a 4x4 video wall with
one video source, see configuration below

G4K Pro User Guide
3.1.2.5. Set up daisy chain in management software
1) Add the quantity of the G4K Pro into Device Count and press Apply button.
a. Give a name for each device if preferred
b. Enter the unique IP address for each device (3.1.2.1)
c. Set the Port to 1024 for all devices
2) Press Connect button to connect all the G4K Pro into one system and users will get the
following users interface
3) Click on the header of 1st device and drag the line to the 2nd device to open the ‘Change
Device Mode’ dialog window to choose the Slave Mode (Daisy Chain mode) for the 2nd
G4K Pro. And then 2nd to 3rd and 3rd to 4th unit.
For a 4x4 video wall with only one video to be displayed across the entire video wall,
the settings are as follows:
G4K Pro 1 Main Device
G4K Pro 2 Slave (get Cascade data, transfer Cascade data)
G4K Pro 3 Slave (get Cascade data, transfer Cascade data)
G4K Pro 4 Slave (get Cascade data, transfer Cascade data)
4) Once the daisy chain relationship between each G4K Pro device has been established,
users need to
a. set up the layout of the screens according to the video wall in Output of
management software (see 3.2)
b. set up the video input window for the video wall in ‘Input’ of G4K Pro
management software (see 3.3)

G4K Pro User Guide
5) Each G4K Pro has 5 modes to be used in daisy chain system.
1. Main Device Show Red Header
Under this Mode, G4K Pro will display the video source from the Main HDMI input (also called
‘local data) in the front of device.
This mode will define the device as the master unit in the system. There should be only one master
device in one system. Normally the first unit is always used as Main Device.
2. Slave(get local data, transfer local data) Show Purple Header
This mode enables the devices to have frame lock with the master device and output the signal
from its own input. It will then transfer its own input source to next G4K Pro device.
3. Slave(get Cascade data, transfer local data) Show Green Header
This mode enables the devices to have frame lock with the master device and output the signal
from master device via HDMI daisy chain. However it will transfer the input source from its own
input to next G4K Pro device.
4. Slave(get local data, transfer Cascade data) Show Blue Header
This mode enables the devices to have frame lock with the master device, but output the signal
from its own input. It will however then transfer the input source from master G4K Pro device.
5. Slave(get Cascade data, transfer Cascade data) Show Grey Header
This mode enables the devices to have frame lock with the master device and output and transfer
the signal from the input source of master G4K Pro device.
6) Change the unit from Slave mode to Master mode
Double click on the device image in ‘Device’ of management software to open full ‘Change Device
Mode’ dialog window and then choose ‘Main Device’ mode to set the unit back to Master mode.

3.1.2.6. G4K Pro Daisy Chain Example
1. Multi video inputs
Each G4K Pro is able to take a 4K video source either from main HDMI Input (Local Data) or from
Daisy Chain input (Cascade Data) from Loop HDMI In port
2. Inputs and Daisy Chain connections using HDMI cables.
Note: The 4th HDMI cable is needed if G4K Pro 1 would work at Slave Mode
