CP Technologies USB to Serial Adapter - Serial adapter - USB - RS-232

The USB Serial Adapter is a dongel with a USB A connector on one end, and a DB9M connector on the other. It provides an external plug-and-play RS-232 Male serial connection to your computer's USB "A" host port, or to an external USB hub's downstream port. The onboard, proprietary circuitry under the DB9 hood guarantees 100% compatibility with all serial RS-232 devices. Installation is easy. Simply plug a serial device into the UC-232A adapter and plug the USB port into the computer. No IRQs are needed, so there are no IRQ or Com port conflicts.
