Continued on back. Description ELPRO wireless serial modems allow RS232 and/or RS485 serial host devices to communicate transparently. Messages are routed between devices as broadcast (simultaneous transmission of same message) or controlled mode (i.e., specific unit addressing). 455U-D has three available models in terms of functionality: Bell 202 or V23 functionality (455U-B). Օ 405U-D end of life compatibility mode (455U-C). Full functionality RS232/485 modem, addressed/broadcast modes/ Optimal Path Routing for Modbus RTU, DF1 and DNP-3 (455U-D). Features Օ Licensed/license-free radio channels, suitable for most countries (150, 220, 360-512MHz, 10mW - 5W RF power option availability). Wireless data rates up to 19.2Kbps. Օ Diagnostics/Configuration via RS232 port. Separate RS232 and RS485 ports. Օ Remote configuration via wireless channel. 128 bit AES security encryption. Օ Configurable, redundancy, repeater networking. ©2011 Cooper Bussmann www.cooperbussmann.com/wireless 1211 BU-SB11845 Page 1 of 2 Data Sheet # 7915 COOPER Bussmann
