Introduction
Wiring
Note: Each module needs independently wiring.
Basic Network Settings
Connect the cable and power on the device as instructed in the installation manual. Then, revise the terminal network parameters according to the live environment. There are two methods:
· Terminal Device Scanning Tool 1Under the menu of [optical disc:tool software] find “DevConfigTool” and run it, after starting, input the default password “123456”.
5 www.nordencommunication.com
2Please select the Mandatory configfrom the right menu, then filling each correct parameters in the [terminal parameter]. It will be finished IP parameter configuration once pressed “sending parameter”.
Remark: · When using a Windows 7 system, run the software in administrator mode
and disable all firewalls and related security software. · The terminal scanning tool can configure network parameters for only one
terminal at a time. Ensure that the computer is connected to only one target terminal during the configuration process. · Webpage Way Access the web interface of the 4-Channel 2-Way Audio Adaptor, adjust the network parameters based on the site environment, and click “Save” to apply the changes. For detailed steps, refer to the network parameter settings in the user-defined terminal parameters section.

Trouble Shooting
1. Why does the “terminal network services (UDP) start fail” warning display while the server software is starting up?
· If this warning message appears, it usually indicates that the local network connection has been lost. Please check and reconnect the network cable properly, exit the software, and then restart it.
2. Why the terminal is still “offline”? · Check Software Server and Main Controller: Ensure both are running properly. Before launching the server software, disable all firewalls, including the system firewall and any third-party antivirus firewalls. · Verify Network Connection: After powering on the terminal, the network port’s green light should remain steady, and the orange light should flash rapidly. If the green light is off, it indicates a hardware connection issue– check the network cable and switch for damage, disconnection, or malfunction. · Check Terminal IP Settings: Confirm that the terminal ID, server IP, local IP, and gateway IP are correctly configured according to the network environment. 3.
