450U-E Wireless Ethernet Modem

Key Features:

The ELPRO 450U-E wireless Ethernet modem is a license free wireless transceiver designed to
Provide communications over ultra-range and also operate as an Access Point/Client configuration which functions as a network Bridge/Router, or serving as a Serial Server. The optimized throughputs of the ELPRO 450U-E (19.2kbps) which provides durable and secure two-way wireless communications made it possible for the modem to operate in extremely challenging outdoor environments over obstructed paths such as found in monitoring and control applications.
