USB to Serial

USB to serial converter where a serial port is not available - for example, on notebooks, note books and desktop PCs / servers. Some versions also have optical isolation, so the equipment is protected from overvoltage and interference.

Supports both Open Host Controller Interface (OHCI) and Universal Host Controller Interface (UHCI). Complies with USB specifications.
