The Keyspan USA-19HS USB to Serial Adapter is a perfect solution and is widely recommended by serial device manufacturers for its dependability, simple plug-and-play operation, and device compatibility.
Looking for a way to connect a serial device to the USB port on your PC or Mac? Our USB High Speed Serial Adapter provides a simple and reliable solution.
