Radios, GPS, CNC machines, telescopes, embroidery machines, fuel injection controllers, 
PDUs, network switches and other devices.

Gold-plated contacts and rugged construction combine to offer a reliable connection 
between the computer and serial peripherals for consistent, trouble-free performance.
