7.4 Computer Interfacing

The USB/RS485 Interface Converter (E-USB485) allows you to connect your sensor to computers by using a USB
interface.
With auto configuration, the converter can automatically configure RS485 signals without external switch setting.
The converter is equipped with 3000 VDC of isolation and internal surge-protection to protect the host computer
and the converter against high voltage spikes, as well as ground potential difference. When the converter is
connected, the computer gets one virtual COM port.
In serial RS485 communication, the Endurance sensor supports the 2-wire / half duplex mode only!
