Introduction

The LRA-900-E is an Ethernet to radio device designed for remote communication operating in a transparent way and exploiting the physical layer of LoRa (Long Range) transmission technology. By using the VxComm Driver/Utility, the built-in RF port of the LRA-900-E can be virtualized to a standard PC COM Port in Windows. Therefore, users can transparently access RF data over the Internet/Ethernet via the COM Port program. The LRA-900-E provides a maximum line of sight (LOS) transmission distance of 1500 meters at an RF bit rate of less than 10 kbps. In order to overcome the interference that may be encountered in harsh environments, the LRA-900-E 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-E networks are adjacent. The RF channels and the Group IDs can be configured in order to distinguish and control the different LRA-900-E networks.
