The 450U-E Industrial 802.11-based Wireless Ethernet module provides wireless connections between Ethernet

devices and/or Ethernet wired networks (LANs). The 450U-E is a fixed frequency wireless transceiver that operates

within the 360 MHz to 512 MHz frequency spectrum in one of eight 20-MHz frequency bands, depending on the

model purchased.

The 450U-E module provides two serial connections and an Ethernet connection. It is possible to use all three data

connections concurrently, allowing the 450U-E to act as a device server where wireless connections can be made

between serial devices and Ethernet devices. The 450U-E also provides functionality between serial Modbus RTU

devices and Ethernet Modbus TCP devices. Appropriate driver applications will be required in the host devices to

handle other protocols. The modem is capable of passing VLAN tagged frames.

The Ethernet connection is a standard RJ-45 connection that will operate at up to 100 Mbps. The module will

transmit the Ethernet messages on the wireless band at rates between 1 and 19.2 Kbps, depending on model,

band, encryption methods, and radio paths.
