1.1 Description of the device
TheSGseriesofsmartgatewaysareintendedtoconnectvarious equipment into communication
network. The gateway has built‐in two optical (IR) communication ports and the RS485 serial
communication with the MODBUS protocol. RS485 communication enables data transmission and
consequentlytheconnectionofcommunicationgatewayintotheRS485networkandcommunication
with various equipment, consisting of RS485 communication (e.g. energy meters, latching switches,
powermonitoringdevices,etc.),viaMODBUS.
TheSGseriesalsoconsistofpulseinputandtemperaturesensor(Pt1000)input.
