Description
MM44D Super High Power 25Watt 50KM ~ 80KM Serial Data Radio Data Link DTL RS232 / RS485 / TTL

1 Introduction

MM44D is a Serial Data Transmission Radio with excellent RF performance and very low delay, it supports most wide frequency ranges from 136MHz ~ 174M, 220MHz ~ 240MHz to 410MHz ~ 470MHz and configure baud rate range and air data rate range from 1200bps to 115200bps.

The radio supports Line-Of-Sight (LOS) and Non-Line-Of-Sight (NLOS) wireless data transmission up to 80 kilometers.

The radio has RS232 and RS458 serial port in a one DB9 connector and supports to customize TTL serial port.

 

2 Applications

Sensor Data Transmission, e.g. Temperature, Humidity, Water Level, Chemical Gas Concentration

Telemetry Data Link, e.g. Vessel Monitoring, Pipeline Monitoring, Heat Network Monitoring, Water Level Monitoring, Environmental Protection Monitoring

Industrial Remote Control, e.g. Industrial Automation Process Control, Robot Control, Unmanned Vehicle Control
