MU-4-434 - 1

Embedded low power radio modem The MU-4-434 is an embedded radio modem operating in the 434 MHz ISM band. Dedicated commands, specially designed for wireless applications are provided for building a range of wireless systems 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 RE Directive and carries the CE and UKCA marking. The relay feature allows you to extend the range by using additional units (up to 10 units). UART interface with simple command protocol 127 RF 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 (TX) Optional transparent mode CE / UKCA marking Applications ・ Environment monitoring, various measuring applications ・ Remote control for industrial equipment ・ Various alarm and monitoring systems Applicable standard Communication method Simplex, Half duplex Emission type 10 mW / 1 mW selectable (Nominal, Contact 50 ohm) Channel spacing Receiver sensitivity Operating temperature Supply voltage Supply current Reference data * Effective radio communication speed: About 3,400 bps (Conditions: One-way communication, no error correction, 25 C) * Range: About 600 m (Conditions: One-way, no error correction, 25 C, line of sight distance, antenna height of 1.5 m, vertical antenna) Serial interface Communication method Asynchronous / UART Data speed Flow control RTS / CTS hardware flow control Other parameters Data length: 8 bit, Parity: (None, Odd, Even), Stop bit: 1 or 2 Specifications are subject to change without prior notice Sales Division 7557-1 Hotaka, Azumino, Nagano 399-8303, Japan Tel:+81-(0)263-82-1024 F
