Description

StarTech ICUSB232INT2 2-Port RS-232 Serial Adapter Card

Overview

The StarTech ICUSB232INT2 provides a reliable method to integrate legacy serial devices into modern systems lacking native RS-232 ports. This adapter card connects via an internal motherboard header, offering two standard DB-9 serial ports. It's designed for environments where you need to connect devices like industrial controllers, barcode scanners, or older diagnostic equipment that rely on serial communication. The ICUSB232INT2 model ensures you can maintain connectivity with essential hardware without requiring a full system upgrade.

Compatibility

This adapter card is compatible with systems featuring an available IDC (10-pin, Motherboard Header) connector. It supports standard serial communication parameters including 7 or 8 data bits, 1 or 2 stop bits, and various parity options (None, Odd, Even, Space, Mark). The maximum baud rate supported is 115.2 Kbps, sufficient for most serial peripherals. It functions within an operating temperature range of -10°C to 80°C (14°F to 176°F).

Installation Notes

Installation requires opening the computer chassis to connect the internal IDC header to the motherboard. Ensure the system is powered off and grounded before proceeding. The card itself is a standard profile bracket, suitable for most desktop PC cases. The included 24-inch cable provides ample reach from the motherboard header to an accessible expansion slot area.
