Description

1 Introduction

MM37D 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 12 kilometers.

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

2 Applications
