How to install StarTech ICUSB2328I

• Power down the host system if required by your environment and choose a mounting location that provides adequate clearance for the eight DB9 connectors and the USB cable.
• Mount the ICUSB2328I using the included DIN Rail clips in a control cabinet or on a wall using the brackets. Ensure the unit is secured and does not obstruct other components or ventilation.
• Connect the ICUSB2328I to your computer or embedded system via a USB-A port using a standard USB cable. Use the cable length that fits your installation while keeping the device accessible for maintenance.
• Power on the host system (if needed) and install the FTDI drivers for your operating system. The FTDI drivers enable the USB-to-serial functionality and ensure stable communication with all eight ports.
• Plug your RS-232 devices into the eight DB9 ports on the ICUSB2328I. Verify each device’s baud rate, parity, stop bits, and flow control settings in your software to ensure proper communication.
• Open your application or operating system’s device manager or serial terminal software to observe the eight virtual COM ports presented by the hub. Confirm that each port maps correctly to the corresponding RS-232 device and that data transfer is functioning as expected.
• Leverage COM port retention to maintain consistent port numbers across reboots and USB re-enumeration, minimizing reconfiguration time in production or testing environments.
• Test the setup with representative data flows to verify timing, latency, and reliability across all eight channels. If you encounter issues, recheck cable integrity, baud rates, and driver versions.

Frequently asked questions

• Can I use all eight ports simultaneously? Yes. The ICUSB2328I is designed to support eight independent RS-232 serial ports from a single USB connection, enabling concurrent communication with multiple serial devices.
• Do I need an external power supply? No. The device is powered via USB from the host system in typical configurations, simplifying installation and minimizing cabling complexity.
• Is COM port retention automatic? The device is designed to retain COM port numbers across re-enumeration, making software configuration more predictable and reducing the risk of port conflicts after reboots or reconnects.
• Which operating systems are supported? Drivers are available for major operating systems, including Windows, Linux, and macOS. Check FTDI’s driver pages and StarTech’s resources for the latest compatibility notes and installation guidance.
• What kind of environments is this hub suited for? With an industrial metal enclosure and DIN rail/wall-mount options, it is well-suited for automation panels, data acquisition systems, manufacturing equipment, and lab environments where robust serial connectivity is required.
• Can I daisy-chain other USB devices with this hub? Yes. Since it is a USB 2.0 hub-based solution, you can connect other USB devices to the same host, provided you respect power and bandwidth considerations.
• Are RS-232 ports individually configurable? Each port operates as a standard RS-232 interface. Baud rates and serial settings are configured in your host software per channel to suit each connected device.
