3. Connection Set up
3.1. RS232 wiring
RS-232 control, baud rate 9600, 3-Pin Phoenix connector
TX Pin, G44--->PC
RX Pin, G44<---PC
3.2. RS232 and Ethernet Connection
Connect the G44 unit with the control PC using either CAT cable or wired serial cable.
4. G44H Software User Guide
Users can run the G44H.exe software directly without installation. Software is on the disk in the
package or you can download it from the SEADA website. Double click the G44H software to get the
UI as below
There are 8main tabs in this software to help users set up and control the G44-HDMI video wall
controller.

G44 HDMI User Guide
4.1. Matrix Switch
Users can connect the G44 device to control PC and set up the device as matrix switcher in this section.
4.1.1. Connect to the G44 via UART for RS232
Connect the G44 to the control PC with a serial cable
1. Click the dropdown menu right of Port to select the COM port.
2. Click the button right of Status to connect to the device (the button will change from
Disconnected to Connected)
3. If the COM port does not exist, then the PC tool will show a
message of ‘COM x not detected!’. If this message occurs, you
should start from step 1 after you connect a serial cable to the
computer.
4. If the device or the connection is faulty, then a message will
occur after 3 seconds. Please check if your device or hardware
connection is correct.
5. If all is right, the software will check all the parts of the
device. It probably takes 5 seconds and it will show
’Reading: All information success!” when finished.
4.1.2. Connect to the G44 via Network
The default IP address for G44 controller is 192.168.0.247,
Users need to change the IP address of the control PC to the same network segment as the G44.
•Change the ‘Obtain an IP address automatically’
to ‘Use the following IP address’ to set up a static IP address of TCP/IPv4 in Ethernet Properties
➢IP address: any address between 192.168.0.2 and 192.168.0.254 except the address which has
been taken by the G44
➢Subnet mask: 255.255.255.0, Default Gateway: 192.168.0.1
•Once the control PC IP address having been set up, connect PC to either the RJ45 ports of
G44 controllers via a network cable and then press the Connect button to connect the device.
4.1.3. Matrix Switch Routing
Users can switch and assign different inputs to the
selected outputs in the matrix. The name of the
input/output can also be changed by selecting the
default name –Input1/Video-Output1 and
replacing it with the chosen name.

G44 HDMI User Guide
4.1.4. Allset, Recall, Save As and Reset
•The Allset dropdown menu helps the users select a single input to be displayed on all of the
screens (i.e. Allset Input 4 would display Input 4 on Output 1, Output 2, Output 3 and Output4)
•Recall Mode: Recall a preset layout. The device supports maximum 8 scenes.
•SaveAs Mode: Save up to 8 preset layouts
•Reset: Reset the unit to default factory configuration.
•EDID:
✓Read: read the EDID of the selected output
✓Save: save the displayed EDID after ‘Read’
✓Open: open an EDID from previous saved EDID
✓Write: write the current displayed EDID onto selected input
to customized input EDID
4.1.5. Audio Matrix
•Follow Video Mode –The
LR and Toslink audio outputs will
follow the video output embedded
audio. Meaning that analog audio
output 1 will have the same audio as
HDMI output 1, analog audio output
2 will have the same audio as HDMI
output 2 etc.
•Manual Mode –This allows the user to control the audio source separately from the HDMI
output ports. The analog audio output can be from any analog audio input port or any
embedded audio of HDMI input.

G44 HDMI User Guide
4.2. Advanced Switch
The Advanced Switch tab will repeatedly send a batch of matrix selection commands at the interval
time specified in ‘Send cmd Periodically’
1. Select one or more outputs.
2. Select one input.
3. Use the arrow button (-->) to assign that input to the selected output or outputs.
4. When all required selections have been set up, click the Start button to run the commands.
The available options are:
•All outputs send combined –Include all outputs that have the content from the same input
as a single command.
•When others finished, start a next loop –Wait for all commands in the previous action having
been completed before sending the next batch of commands.
•Stop cmd after one loop –Only send the commands only once, no looping.
•Select all outputs –Selects all outputs when checked. Unselects all outputs when unchecked.
•Start –Begin the command cycles.
•Stop –Stop the command cycles.
