Premium USB to Serial Port RS232 Adapter For PC Mac Linux
This USB to serial port adapter cable is a great accessory item for laptop and desktop computers that do not have a COM or DB9 serial port. 

Most computers these days do not have RS232 (DB9) ports, making the use of legacy data peripherals and communication devices requiring COM port connection almost impossible.

This USB to serial port RS232 adapter is easily configured so those legacy or newer serial port devices can continue to be used through USB hookup with new computer without any interruption. 

This adapter cable simulates the traditional Serial/RS232/COM/DB9 port on most operating systems, allowing the existing COM port related applications to be easily migrated through USB hookup.

This simple and reliable adapter provides engineers or technicians with external way to control and monitor their serial port-based equipment by sending RS232 commands through computer. 

This serial link adapter cable is widely used in many industrial and consumer applications. Many automation systems, scientific instruments, data modems, alarm systems, POS systems, barcode scanner, label printer, access control, surveillance DVR, etc. are still relying on RS232 for external and distant control.

This USB serial port adapter cable supports all PC, Mac or Linux systems with maximum baud rates up to 920 Kbps for rapid performance. 

The supported operation systems including Win10, Win8.1/8, Win7, XP, Vista, 2000 for PC and Mac OS 10.x, 9.x or older version and Linux 2.4.31 and later.


  • Cost-efficient USB to serial port connectivity solution for transforming USB port of laptop/desktop computer into a Serial RS232/COM DB9 port.
  • Easily configured so legacy devices can continue to be used with new computers without changes to the applications written for them.
  • Simulates as a standard COM port in most operating systems so the setup can be easily migrated through new USB hookup.
  • Simple and reliable adapter for controlling and monitoring any serial port-based equipment by sending RS232 commands through computer. 
  • Easy setup and installation.
