Overview

The Rocstor Premium 3ft USB to Null Modem Serial Adapter transforms an available USB 1.1 or USB 2.0 port into an RS232 Null Modem serial DB9 port, providing a direct solution for DCE/DTE conflicts without the need for additional cross-wired serial cables or adapters. This adapter features COM retention, ensuring that the same COM port value is reassigned if the cable is disconnected and reconnected or if the system is rebooted.

The integrated FTDI USB chipset offers enhanced customization, advanced features, and superior compatibility across various operating systems, including Windows®, Windows CE, Mac OS, and Linux. Ideal for professional and personal use, this adapter delivers reliable and efficient connectivity, backed by Rocstor's 2-Year Warranty.
