ICUSB232INT1 - USB to RS232 Serial Adapter for Motherboard Header Expansion

The ICUSB232INT1 USB to RS232 Serial Adapter is designed to add an RS232 serial port to desktop systems that have an available USB motherboard header. This internal solution eliminates the need for external adapters or PCI slots, making it a clean and efficient way to connect legacy serial devices. It is ideal for users who need to interface with older equipment that relies on serial communication.

This adapter is bus-powered, meaning it draws power directly from the USB motherboard header without requiring a separate power source. It supports COM port retention, ensuring the same COM port number is assigned after a system reboot. This feature simplifies device configuration and reduces setup time for users working with serial peripherals.

The ICUSB232INT1 is compatible with various USB host controllers including UHCI, OHCI, and EHCI, and works with USB 2.0 Full Speed. It offers both synchronous and asynchronous bit bang interface options with RD# and WR# strobes, providing flexibility for different applications. The inclusion of FIFO receive and transmit buffers helps maintain high data throughput during transfers.

The adapter is particularly useful for system builders and professionals who need to connect industrial sensors, automotive equipment, bar code scanners, receipt printers, or serial modems. Its internal design keeps the setup tidy and avoids clutter inside the PC case. It also supports a wide range of operating systems with Microsoft WHQL certified drivers for reliable performance.
