USB to RS232 serial adapter with DB9 female port

This cable converts a USB connection to an RS232 serial interface ending in a DB9 female connector. It is designed for users who need to link modern computers with legacy serial equipment such as industrial controllers, networking gear or point-of-sale devices. The dual-chip design handles the USB-to-serial translation internally.

Sustained data transfer through dual-chip

The integrated dual-chip solution manages continuous serial streams without relying on a single controller to handle all buffering. This arrangement helps maintain stable communication during long sessions with devices that send or receive constant data. The cable draws operating power directly from the USB bus so no external supply is required.
