how to install StarTech.com USB to Serial Adapter Hub - 8 Port

• Connect the USB cable from the hub to a free USB port on your computer.
• Power on your computer and allow the operating system to detect the device. If prompted, install the FTDI drivers from Windows Update or the StarTech support site. The 8 RS-232 ports should appear as eight separate serial COM ports.
• Attach your RS-232 peripherals to the eight DB9 ports on the hub. Use appropriate null-modem or straight-through cables based on your device requirements.
• Open your terminal, data-acquisition, or diagnostic software and configure each port (COM1 through COM8) with the correct baud rate, parity, data bits, and stop bits as specified by your devices.
• Test each connection individually to confirm data integrity and ensure there are no port conflicts. If devices require higher current, ensure your computer’s USB port can supply adequate power or consider a powered USB hub if needed.
