Introduction

The LRA-900 is a RS-232/485 to radio device designed for remote communication operating in a transparent way and exploiting the physical layer of LoRa (Long Range) transmission technology. The LRA-900 provides a maximum line of sight (LOS) transmission distance of 1500 meters at an RF bit rate less than 10 kbps. In order to overcome the interference that may be encountered in harsh environments, the LRA-900 allows the RF transmission bit rate to be configured to a minimum of 250 bps, enhancing the capability of the modem to resist noise and other interference. Additionally, the RF channels and Group IDs are adjustable, which is helpful to avoid interference encountered when two LRA-900 networks are adjacent. The RF channels and the Group IDs can be configured in order to distinguish and control the different LRA-900 networks.
