FTDI USB to RS232 Adapter - 2 Port Internal Motherboard Serial Port - Bus Powered (ICUSB232INT2)

This USB to serial adapter allows you to add two RS232 ports to a desktop computer that has an available USB motherboard header. It is designed for internal use within the PC case, eliminating the need for external cables or adapters. The device is bus powered, meaning it draws power directly from the USB port and does not require a separate power supply. This makes it a convenient and space-saving solution for users who need to connect legacy serial devices to modern computers.

The adapter uses a single-chip USB to asynchronous serial data transfer interface, ensuring reliable and efficient communication between the computer and serial peripherals. It includes FIFO receive and transmit buffers, which help maintain high data throughput and reduce data loss during transmission. This makes it suitable for applications that require consistent and fast data transfer, such as industrial automation or data logging.

The ICUSB232INT2 is compatible with USB 2.0 Full Speed standards, ensuring it works with a wide range of modern motherboards and operating systems. It supports COM port retention, which means the assigned COM ports remain consistent even after system reboots. This feature is particularly useful for applications that rely on specific COM port assignments for device communication.

Installation involves connecting the adapter to the USB header on the motherboard and securing it within the PC case. No additional drivers are typically required, as the device is plug-and-play compatible with most Windows operating systems. The compact design allows it to fit easily into tight spaces inside the case without obstructing other components.
