W3100G IP Modem is a kind of wrieless terminal device that provide data transfer function by public GPRS network.. It has been widely used on M2M fields.  Features:
1. Plug and Play
• True Transparent Data Transfer
• Protocol independent
2. Rich Data Options
• TCP for reliable data transfer
• UDP for fast and bulk data transfer
• App protocol for secure data transfer
• Methods of serial data packetization
3. Robust Operation
• Constant self test
• Self reset and recovery
• Data buffering
• Support auxiliary data center
4. Easy Control
• Remote configuration by SMS or GPRS
• Remote activation by SMS, call or Serial command
• Auto SMS of IP for dynamic IP SIM card
5. Always ON Connection
• Heart beat to maintain socket connection
• Auto socket re-connection if drop
• Time to live timer for network checking
6. Flexible Operation
• Server or client mode for connection
• Static or dynamic IP
• Can work as a standard GSM/GPRS modem
• Can work as virtual wire
• Support RS232 / 485 / 422 hardware options
• Local / Remote firmware update via GPRS
• Direct control by HyperTerminal commands
• Provide Center Manager software
7. Flexible Backend
• Direct porting via TCP port or virtual serial port
• API for software developer
• OPC for SCADA developer (For 4-20mA only)
• PLC commands for M2M developer
