The adaptor allows the connection of devices with optical serial interfaces using optical fiber with a PC/laptop through USB. The adaptor appears as virtual COM port in the device manager. Standard baud rate up to 115kbps cab be used.


The signals DTR, CTS, DSR and DCD are not supported. Otherwise the interface can be used without any restrictions. The optical interface uses fiber optic transmitter/receiver modules (wavelength 650nm). Therefore the data transfer is dobe potential-free via optical fiber (1mm POF / 200µm HCS) with simplex or duplex connector.
