Serial adapter cable Exsys USB 2.0 to 2-port RS-232 EX-13072HM metal housing

Exsys USB 2.0 to 2-port RS-232 EX-13072HM metal housing is a compact adapter cable that converts a USB Type-A connection into two RS-232 serial ports. Designed to connect legacy serial devices—such as modems, industrial controllers, POS terminals and laboratory instruments—to modern computers with USB interfaces, the adapter provides a reliable serial link in environments that require frequent connection and disconnection and a durable enclosure.

Advantages

The adapter combines USB 2.0 connectivity with two RS-232 ports in a single unit, enabling simultaneous connection of two serial devices through one USB port. Its metal housing improves mechanical durability and shielding compared with plastic enclosures, which is useful in industrial or high-traffic setups. The plug-and-play nature on many operating systems simplifies deployment, while providing the stable serial communication required for legacy equipment.

Suitable for

• Connecting modems and serial communication devices to modern PCs and laptops
• Industrial automation equipment and PLCs that use RS-232 interfaces
• Point-of-sale (POS) systems and receipt printers with serial ports
• Laboratory instruments and measurement devices requiring reliable serial links

Key specifications

• Interface: USB 2.0 Type-A to two RS-232 ports
• Enclosure: metal housing for improved durability and shielding
• Port count: 2 independent RS-232 serial ports
• Compatibility: connects legacy RS-232 devices to USB-equipped systems

How to use

Connect the adapter's USB Type-A plug to an available USB port on the host computer. Attach serial devices to the RS-232 ports using standard serial cables. Install any required drivers provided by the operating system or vendor if automatic recognition does not occur. Once drivers are installed and the ports are recognized, configure the serial port parameters (baud rate, parity, data bits, stop bits, flow control) in the host application to match the connected device.

Recommendations

For stable operation, use high-quality RS-232 cables of appropriate length and avoid routing them alongside high-voltage power lines. Verify driver compatibility with your operating system and test communication settings with terminal software before deploying the adapter in critical systems. The metal housing provides better shielding; ensure secure mounting and strain relief where frequent plugging and unplugging may occur.
