Serial Cable EXSYS EX-1311-2 USB Type-A DB-9 Black 1.8 m

The EXSYS EX-1311-2 is a 1.8 m USB 2.0 to RS-232 serial cable with a USB Type-A connector on one end and a DB-9 (RS-232) connector on the other. It provides a single high-performance 16C550-type UART compatible RS-232 serial port and enables instant COM port expansion for PCs, thin clients or servers via the USB 1.1/2.0 bus. The cable is RoHS-compliant, CE and FCC certified, and weighs approximately 160 g.

Advantages

The cable offers plug-and-play installation without opening the computer case and supports hot-plugging while the system is running. Its 16C550-compatible UART ensures broad compatibility with legacy serial devices. The included hex nuts can be used as an alternative to screws for secure connector fastening when required.

Suitable for

• Connecting serial devices (modems, industrial controllers, POS terminals) to modern PCs
• Expanding COM ports on thin clients and servers via USB
• Field service and maintenance tasks requiring temporary serial connections

How to use

Connect the USB Type-A plug to an available USB 1.1 or 2.0 port on the host computer. Attach the DB-9 connector to the serial device and fasten using the supplied hex nuts or the device screws if available. The operating system should detect the new COM port; install drivers if the OS does not provide native support. After installation, configure serial communication parameters (baud rate, data bits, parity, stop bits) in the host application.

Recommendations

Use the EX-1311-2 for short- to medium-length connections (up to 1.8 m) in controlled environments. Avoid exposing the cable to excessive moisture, extreme temperatures, or heavy mechanical stress to maintain reliable data transfer and connector integrity.
