805U-E Wireless Ethernet Modem

Key Features:

The ELPRO 805U-E wireless Ethernet modem is a license free wireless transceiver designed to
Provide secure two way communication over long range up to 5 KM at 869 MHz and up to 500 mW.
It can also function in Access Point/Client configuration, functioning as a network Bridge/Router, or serve as a Serial Server.

• 802.11, 869MHz fixed frequency for licensefree use in Europe and South Africa.
• Single channel 868.525MHz, 500mW (10% duty cycle factor) or 869.875MHz, 5mW (100% duty cycle factor), up to 72kpbs (configurable) throughput to conform to European regulatory compliance.
• Bridge/ Router, Access Point/ Client functionality configurable, reducing inventory costs.
• Serial client/ server/ multicast functionality (point-point; point to multi-point) with simultaneous use of RJ45, RS232, RS485 ports.
• Modbus TCP to Modbus RTU Gateway/Modbus Master for I/O transfer with additional slave I/O via ELPRO’s 115S expansion units.
• Spanning Tree (self heal) functionality.
• Encryption to 128 bit AES military grade.
• MAC address/ IP filtering reducing network traffic.
• Online network diagnostics/ configuration.
• Onboard DI/O channel (failure/ external status).
