1. Introduction
The LRA-900-E is a 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 datas over the
Internet/Ethernet via COM Port program.
The LRA-900-E provides a maximum line of sight (LOS) transmission distance of 1500 meters at
an RF bit rate 10,000 bps. 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.

1.1. VxComm Technology
In general, writing a TCP/IP program is more difficult than writing a COM Port program. Another
issue is that perhaps the existing the COM Port communication system was built many years ago
and is now outdated.
As a result, a new technology, VxComm was developed to virtualize the RF Port of the
LRA-900-E to become a COM Port on the PC and allow up to 256 COM Ports to be used on a
central computer. The VxComm driver saves time when accessing LRA-900-E devices through
the Ethernet without the need for reprogramming the COM Port software on the PC.

1.2. Web Server Technology
Web server technology enables the LRA-900-E to be configured via a standard web browser
interface, e.g. Google Chrome, Internet Explorer, or Firefox, etc. This means that it is easy to
check the configuration of thet LRA-900-E via an Ethernet network without needing to install any
other software tools, thereby reducing the learning curve required for maintaining the device.
