Overview

The SMG-1100 series features two software selectable RS-232/422/485 ports, one Ethernet port, and quad-band GPRS/EDGE 900/1800/850/1900 MHz for cellular communication. The SMG-1100 series provides a sophisticated wireless M2M solution for distributed Modbus devices. The SMG-1100 networks Modbus devices with Modbus RTU/ ASCII protocols can work well via GPRS/EDGE or Ethernet to Modbus TCP, and each serial port can support up to 31 serial slaves to IP network. Implemented with the protocol conversion functionality, the SMG-1100 can serve both serial master and slave and the built-in IPsec function guarantees that data transmission is encrypted even in a wireless environment.
