The USB-335 SmartPipe Protocol and Code Converter allows RS-232 data to be fed directly into a USB port as keyboard data. The standard ASCII code set, common in RS-232 applications, does not correspond to the codes of the standard USB keyboard, requiring translation between ASCII and USB keyboard codes. The Vetra USB-335 Protocol Converter performs these ASCII code to USB keyboard code translations. Additional keyboards can also be connected via the on-board 2 port hub, or directly into any other USB port.The connection of a standard keyboard is optional and not necessary for the USB-335 to operate.
