9.1.12. USB to RS232/422/485 converter (E-USB485)

The USB to RS232/422/485 converter (E-USB485) is for the direct adaptation of an Endurance
series device to a standard PC via the USB-interface. The converter supports auto configuration
in data format, baud rate and RS485 data flow direction control. It is able to automatical
configure RS-232, RS-422 or RS-485 signals to baud rate without external switch setting.
Furthermore, the converter is equipped with 3000V DC of isolation and internal surge-protection
on each data lines to protect the host computer and converter against high voltage spikes, as
well as ground potential difference. Please see under chapter 5.3.5, Computer Interfacing via
RS485 link for detailed system interfacing.
