## Long description

Cabletech KPO3431-1.5 USB to RS-232 adapter cable converts a USB port into a DB9M serial interface, enabling wired communication with legacy serial devices. The 1.5 m length gives sufficient reach for desktop and rack-mounted equipment while the compact DB9M connector maintains compatibility with standard RS-232 ports. The cable has a durable blue outer jacket designed for repeated handling in office, industrial or retail environments. The adapter supports plug-and-play installation on most systems though a driver may be required for some operating systems.
Advantages
The adapter provides a straightforward and cost-effective way to add an RS-232 serial port to modern computers that lack native COM connectors. Its 1.5 m length balances flexibility and cable management while the molded DB9M connector ensures a secure physical connection. The blue sleeving increases visibility behind workstations and in service racks, and the cable’s construction is intended to withstand normal bending and daily use. Compatibility with a broad range of devices such as modems, industrial controllers and POS terminals simplifies integration into existing setups.
Suitable for
 Connecting legacy modems and serial communication devices to modern PCs
 Industrial automation equipment and PLCs that use RS-232
 Point-of-sale terminals and receipt printers with DB9 serial ports
 Measurement, testing and laboratory instruments with serial interfaces
 Configuration and maintenance of networking or security devices requiring serial console access
Key specifications
 Interface: USB (host) to RS-232 DB9 male
 Cable length: 1.5 m
 Connector type: DB9 male (serial)
 Outer jacket: durable blue sleeving
 Installation: plug-and-play on most systems; driver may be required for some OS
How to use
Plug the USB end into an available USB port on the computer and connect the DB9M connector to the serial port of the target device. If the operating system recognizes the adapter automatically, the new COM port will appear in device manager or the system’s serial port list. If a driver is required, install the manufacturer’s driver following the provided instructions before connecting the device. Verify communication settings such as baud rate, parity, data bits and stop bits in the host application or terminal software to match the serial device’s configuration.
Usage recommendations
For reliable operation, avoid sharp bends and excessive tension on the cable, keep connectors free of dust and secure DB9 connections with appropriate thumb screws or retention if available. When using in industrial environments, route the cable away from high-voltage or high-current sources to reduce interference; if communication issues arise, confirm driver installation and serial port settings.
