Serial to IP Modem (DTU)

SDS100/SDS200 is a Industrial Serial to IP Modem (called Serial to Ethernet Modem, RS232/RS485 to Ethernet Coverter, Serial Device Server, DTU as well), it convert the serial data (RS232/485) into IP data and then transfer to data center through Ethernet/WiFi network. It adopts standard industrial terminal interface, product design meets the industrial standard, embedded TCP/IP, Modbus and other protocols, helps the transparent data communication from user equipment to data center.

Industrial grade rugged design for SDS100/SDS200 Serial to IP Modem, make it stable operation under harsh environment. Wired Ethernet and WiFi network options, small and compact design make it easy to deploy in industrial environment. It had been widely applied in kinds of serial device fields of Industrial Automation, SCADA, Smart Grid, Oil Field, Environment Protection, Access Controller, Attendance System, Building Automation Controller, Telco Infrastructure,etc.
