2.4 GHz Modem Radios

Modems are used to connect PLC's in industrial environments. They are suitable for accessing field data loggers or data-acquisition units in process plants. 2.4 GHz device (Direct Sequence Spread Spectrum) are now available which share the following features:

• 10/100 BaseT Ethernet plus RS232/RS485 serial ports.
• Military-grade AES security encryption of wireless data.
• Firewall protection and efficient wireless management.
• Message filtering at MAC & IP address level.
• Configuration and diagnostics via web-browser
• Remote configuration and diagnostics via the wireless link
• Automatic changeover to another Access Point if the wireless link fails (mesh networking)
• Modbus Master capability for both Modbus TCP and serial Modbus RTU
• Configurable as Access Point / Client; Bridge / Router / Repeater
