how to install StarTech.com USB to Serial Adapter Hub

• Step 1: Connect the adapter to a spare USB port on your computer, industrial controller, or embedded system using a standard USB cable. Ensure the host system is powered and ready to recognize a new USB device.
• Step 2: Attach four RS232 devices to the four DB9 serial ports on the hub, using appropriate serial cables and terminal adapters as required by your equipment. Verify that each device is powered and configured for its communication parameters (baud rate, parity, data bits, stop bits).
• Step 3: If you need a space-efficient installation, secure the hub to a mounting surface. Use the wall-mount or DIN-rail mounting options to fit your enclosure or control panel, ensuring that cables are routed neatly and do not interfere with moving parts or heat vents.
• Step 4: Install the appropriate FTDI drivers on your operating system. FTDI drivers support a wide range of OSes, including Windows, macOS, and Linux, and will establish the virtual COM ports that map to the four RS232 connections on the hub. Reboot or re-plug the device if prompted by the driver installer.
• Step 5: Open your terminal software or data acquisition application and select the four newly created COM ports. Configure each port independently according to the connected device specifications, and test communications to confirm stability and throughput.
