4. Typical application wiring, connection of terminals
DTR and RTS signals are specified for regulator supply. In case of insufficient performance of the
PC communication port it is necessary to use an external power source.
5. Description of device function and setting
Information from regulator is available directly through LCD or you can read them with one of
next communication protocols ( Modbus RTU, Advantech-ADAM ).
