Industrial Cellular Network Servers



2-Port RS-232/422/485, 4 DI, 2 DO, UMTS/HSPA+/GSM/GPRS/EDGE

The iDT2-2420U industrial cellular network server is designed to connect serial devices to wireless UMTS/HSPA+/GSM/GPRS/EDGE networks. With 2 serial ports RS-232/422/485, 4 DI, 2 DO, iDT2-2402U supports the complete Modbus Master/Slave mode and Modbus protocol conversion. For diverse applications, its Share Port function allows the connection with multiple data centers, and all I/O interfaces can act as TCP Client or TCP Server, thus making iDT2-2420U the ideal tool to help you monitor your assets and collect data remotely.
