StarTech ICUSB232INT1 Internal RS-232 Serial Port Adapter

Overview

The StarTech ICUSB232INT1 provides a reliable method to add a legacy RS-232 serial communication port to a system by connecting to an internal motherboard header. This adapter is ideal for integrating older industrial equipment, diagnostic tools, or specific peripherals that rely on serial communication into modern PC builds or server chassis. The ICUSB232INT1 model ensures compatibility with systems requiring a DB9 serial connection, offering a data transfer rate of up to 115.2 Kbps.

Compatibility

This adapter is designed to connect to a standard 10-pin IDC motherboard header, commonly found on many PC motherboards and server systems. The external connection is a standard 9-pin (DE-9) male D-Sub connector, compatible with a wide range of serial devices, including industrial control systems, point-of-sale terminals, and scientific instruments. It supports common serial data configurations including 7 or 8 data bits, and None, Odd, Even, Space, or Mark parity.

Installation Notes

The adapter requires an available 10-pin motherboard header (IDC type). The included 2.0 ft cable connects the internal header to the external DB9 port. Operating temperature range is -10°C to 80°C (14°F to 176°F), with storage temperatures from -20°C to 100°C (-4°F to 212°F). The unit features a 256-byte FIFO buffer to manage data flow efficiently.
