Embedded modem MU-4-434

wirelessISM bandradio data transmission

The MU-4-434 is an embedded radio modem operated in the 434 MHz ISM band designed as the successor to the MU-2-R with improved in-band blocking performance. Dedicated commands, specially designed for wireless application, are provided for building a range of wireless system, from simple control systems to wide network systems. Using the commands, the user can concentrate on designing the application without needing to be aware of the radio protocol and control aspects. Reed-Solomon code is used for forward error correction (FEC) to maintain data integrity and provide highly reliable wireless communication. The MU-4-434 meets the requirements of the European RED and UK Radio Equipment Regulations 2017, carries the CE marking and UKCA marking. The relay feature allows you to extend the range by using additional units (up to 10 units) Features UART interface with simple command protocol compatible with MU-2-R 434 MHz ISM band Pre-programmed 127 channels 10 mW / 1 mW power selectable Error correction with Reed-Solomon code Repeater and auto answer back function Target station receive signal and noise level acquisition Low power operation 42 mA at 3 V / TX Transparent mode RED compliant (EN300 220) Radio Equipment Regulations 2017 (UK) 429 MHz version available (Japan)
