Eaton 245U-E – Industrial Wireless Ethernet Bridge (900 MHz)

Wireless Connectivity

The 245U-E supports both point-to-point and point-to-multipoint topologies, allowing flexible network architectures. It utilizes spread spectrum technology to ensure secure and interference-resistant communication. With up to 1 W transmit power, it can achieve long-range links even in non-line-of-sight conditions. The device also features an integrated serial server, enabling legacy RS232/RS485 devices to connect wirelessly.

Key Features

• Dual Band Operation: 900 MHz ISM band (license-free in most countries).

• Ethernet Bridge: Transparent bridging of Ethernet traffic, supporting IP, Modbus TCP, and other protocols.

• Serial Gateway: Built-in serial server for Modbus RTU/ASCII, DNP3, or transparent serial data over the wireless link.

• High Data Rate: Up to 106 kbps over-the-air data rate.

• Rugged Design: Wide operating temperature range (-40°C to +75°C) and IP30 metal enclosure for harsh environments.

• Security: AES-128 encryption for data protection.

• Diagnostics: LED indicators for signal strength, link status, and activity; web-based management and SNMP.
