How to Install TRENDnet TU-S4

• Unpack the TU-S4 and place it within easy reach of your computer and the four RS232 devices you plan to connect. Ensure the USB cable is not kinked or stretched and that the DB9 cables from your devices are ready for connection to the hub.
• Connect the TU-S4 to a free USB port on your Windows PC or Mac computer using the integrated USB cable. Avoid using USB hubs that are themselves powered through another hub for best reliability, especially when multiple serial devices are in use.
• Attach each RS232 device to a DB9 port on the TU-S4. Use straight-through serial cables that match the device’s port type (DB9 male/female as appropriate) and verify that connectors are firmly seated.
• Power on your RS232 devices if necessary and then power on your computer. In most cases, the operating system will detect the TU-S4 automatically. If prompted, allow install of the recommended drivers. On Windows, you may see new COM ports appear in Device Manager; on macOS, you may see a new serial device in Network or System Information depending on your software setup.
• Open your serial communication software and configure the correct COM/serial ports and settings. Common parameters include baud rate, data bits, parity, stop bits, and flow control. Ensure each connected device is assigned to the corresponding port, and test with a simple command or data transfer to confirm reliable communication across all four ports.

Frequently asked questions

• Which operating systems does the TU-S4 support? The TU-S4 is designed to work with Windows and Mac operating systems, offering easy plug-and-play use with minimal setup.
