Solution 1: Check hardware connections.
Ensure that the Ethernet cables between the Control unit, Tester, and switch are securely connected. Check if the signal lights on the switch's Ethernet ports are constantly light.
Solution 2: Modify the computer's IP address.
The 7th item "SP" in the control unit represents the server's IP address, which is set to 192.168.1.250 .
The server's IP address and the IP address of your computer's local connection (for Windows 10 and Windows 11, this is usually Ethernet) should be the same. Otherwise, you won't be able to establish a connection with the computer.
Modify the IP address of your computer
The Server IP address and the IP address used for the local connection on your computer (e.g., Ethernet on WIN10 and WIN11) must match. Otherwise, you won't be able to connect to the computer.

Note: It is not recommended to configure a single network adapter with two IP addresses.
If you need to connect to a device while having internet access on your computer simultaneously, it"s advisable to configure a wireless network adapter, use a USB-to-Ethernet adapter, or use a computer with dual network cards
