serial USB converter / RS-485 / isolated
DCS770 is used to add an RS-485 connection in a PC computer. It is connected in a USB port, and the drivers create a virtual COM port that can be used just as an ordinary COM port. Even the baud rates and bit configuration can be changed in Windows port settings - these require no jumper settings. DCS770 can be used with a variety of protocols, including Nokeval SCL and Modbus ASCII and RTU.
