FAQ
How many serial ports does this USB adapter provide?
The StarTech.com ICUSB2328I provides eight RS-232 serial ports, allowing you to connect multiple legacy serial devices—such as barcode scanners, PLCs, or printers—to a single USB port on your computer. This eliminates the need for additional expansion cards or separate adapters, streamlining connectivity in environments where serial interfaces are still prevalent.
What operating systems are supported by this adapter?
This adapter is compatible with Windows, macOS, and Linux operating systems, offering broad platform support for diverse IT environments. It uses FTDI chipset technology, which ensures reliable driver availability and stable performance across these systems, making it suitable for mixed-OS deployments in offices, labs, or industrial settings.
Does this adapter require an external power supply?
No, the adapter is bus-powered directly from the USB port, drawing up to 500mA per port without needing an external power adapter. This simplifies installation by reducing cable clutter and power requirements, though it's important to ensure the host USB port can supply sufficient power for all connected devices to maintain optimal performance.
What is COM port retention and why is it important?
COM port retention ensures that the assigned COM port numbers for connected serial devices remain consistent across system reboots. This feature prevents devices from being reassigned to different ports, which can cause configuration errors and downtime in applications that rely on fixed port mappings, such as industrial control systems or legacy software setups.
Can this adapter be mounted in an industrial rack?
Yes, the adapter includes DIN-rail clips for secure mounting in standard industrial racks or control panels, along with wall-mount options. Its compact dimensions of 1.70" H x 3.90" W and rugged metal construction make it ideal for integration into server racks, manufacturing floors, or other space-constrained environments where durability and organized installation are priorities.
What environmental certifications does this product have?
The adapter complies with EU RoHS, REACH, and WEEE environmental standards, restricting hazardous substances and promoting responsible recycling. It is also TAA compliant, making it eligible for government and institutional procurement in regions requiring trade agreement adherence. These certifications reflect a commitment to safety, sustainability, and regulatory compliance in industrial and commercial use.
