## Summary description

StarTech ICUSB232DB25 is a USB to RS232 serial adapter cable with a USB Type-A connector and dual serial terminations (DB9 and DB25 male). The 0.9 m grey cable enables connection of legacy RS232 devices to modern USB ports for serial communication, configuration, or diagnostics. Compact, CE and RoHS certified, it suits industrial equipment, POS systems, networking gear, and embedded devices requiring DB9/DB25 serial interfaces.

## Long description

The StarTech ICUSB232DB25 USB to RS232 Serial Adapter Cable provides a direct connection between a computer's USB Type-A port and legacy RS232 serial devices using either a DB9 or DB25 male serial termination. The integrated 0.9 m (3 ft) grey cable and included DB9-to-DB25 adapter enable straightforward serial communication, configuration, diagnostics and data transfer with equipment that requires a standard RS232 interface. The adapter is compact, CE and RoHS compliant, and designed for use where a native serial port is unavailable.
Advantages
This adapter cable supports both 9-pin and 25-pin serial connections via the supplied adapter, eliminating the need for separate cables. The integrated cable removes the requirement for an additional USB-to-serial dongle plus serial lead, simplifying installation. It offers plug-and-play and hot-swap support for quick deployment and minimal system interruption. Compliance with CE and RoHS standards ensures it meets common regulatory and environmental requirements for industrial and commercial use.
Suitable for
Connecting industrial controllers and automation equipment to modern PCs
Point-of-sale (POS) systems and retail peripherals requiring serial ports
Networking gear, modems and console ports for configuration and diagnostics
Embedded devices, measurement instruments and legacy hardware with DB9 or DB25 interfaces
Key specifications
Connection type: USB Type-A (male) to RS232 (DB9 male) with DB25 adapter included
Cable length: 0.9 m (3 ft) integrated cable
Color: grey
Supported functions: serial data communication, configuration and diagnostics over RS232
Standards and compliance: CE and RoHS compliant
How to use
Plug the USB Type-A connector into an available USB port on your computer and attach the DB9 male connector to the RS232 device. If a DB25 interface is required, attach the supplied DB9-to-DB25 adapter to the DB9 connector and then connect to the device. The adapter supports plug-and-play operation on most systems; if necessary, install the appropriate driver provided by the device manufacturer or available from StarTech to enable full serial functionality. Ensure the serial device and host use compatible communication parameters (baud rate, parity, data bits, stop bits) before starting data transfer.
Usage recommendations
For reliable communication, use the shortest practical cable routing to avoid interference, verify ground connections on industrial equipment, and confirm serial settings match on both ends. If encountering connectivity issues, check driver installation and try a different USB port or host device. This adapter is intended for RS232-level serial signals and should not be used where higher voltage or specialized serial standards are present.
