EXSYS EX-23001 Serial Cable Black 0.5m USB Type-A USB Type-C DB-9

The EXSYS EX-23001 is a 0.5 m serial cable that converts a USB port (Type-A or Type-C) to a DB-9 RS-232 serial interface. It implements a high-performance UART 16C550 and supports connection to PCs, small workstations or servers via USB 1.1, 2.0 or 3.2 buses. The cable is plug-and-play with easy installation while the computer is running and is finished in black.

Advantages

The cable provides an additional RS-232 serial output without opening the computer chassis and offers broad USB compatibility (Type-A and Type-C). The onboard UART 16C550 ensures stable serial communication and the 0.5 m length keeps connections neat while remaining suitable for close-proximity equipment.

Suitable for

• Connecting legacy RS-232 devices (modems, industrial controllers, measurement instruments) to modern PCs
• Adding a serial port to small workstations and servers
• Field service, configuration and troubleshooting where a short, reliable serial link is required

How to use

Plug the USB Type-A or USB Type-C connector into an available USB port on the host computer and connect the DB-9 connector to the RS-232 device. Install any required drivers for your operating system if prompted; many systems will recognise the cable automatically. After installation, configure serial port parameters (baud rate, parity, data bits, stop bits) in your terminal or application to match the connected device.

Recommendations

For reliable operation, use the cable for short-distance connections (desktop or rackmount equipment). Verify driver availability for your OS before deployment in critical systems and match serial settings to the target device. Avoid routing the cable alongside high-power mains cables to reduce interference.
