Our USB converters are designed to convert common computer hardware connectors to USB. Ethernet is another term for a RJ45 network cable (internet connection cable), DB9 connectors are used to transfer data from cameras and other devices, a parallel connector is the style of printer connection used before USB, and the Netlink cable is used to connect two type A devices like computers or external hardware. These USB converters work on both PC and Mac computers and are plug & play compatible.
