Data can be viewed on the Neon Web interface in near real time from any browser and
the comprehensive reporting engine within Neon allows for reporting out to other systems
using email, FTP, and web services, either dynamically, every minute, or on a daily,
monthly, quarterly or annual basis.

The NRL Stand Alone Data logger Implementation
The NRL can be programmed with a program (scheme) in the factory or in a remote office
and then transported to the field to work as a stand-alone system, without the need to
have an internet connection. For this operation method the program (scheme) is
downloaded to the NRL using the Starlog 4 Logger configuration software. The data is
stored in the NRL and can be unloaded using the Starlog 4 Logger configuration software.
The Starlog 4 Logger configuration can be used to set up legacy logger emulations, such
as the Star logger and Prologger, so applications using these older loggers can continue
using the newer NRL models. If the emulation modes are used, the new features available
in the NRL are not available. Unidata suggests the program (scheme) should be updated
to utilise the features available in the newer NRL models.
1.4
The NRL Full Protocol Implementation - Internet Connection Required
The Internet provides the transport mechanism between the Neon Servers and the
telecommunication provider gateways. This means that NRL units can be used anywhere
in the world provided there is an internet connection available. The connection to the
internet can be via a cell phone data service, a satellite service or a Wi-Fi or Ethernet
connection.
With the full protocol service the communications between the NRL and the Neon Server
are closely coupled and each transmission is checked and acknowledged, such that a
beak in communications does not result in lost data. Rather the NRL attempts to
communicate with the Neon Server on a pre-set schedule and continues to log and store
data and then re-send if and when the communications link and/or the Neon Server
service is restored.
Also the remote NRL can be configured online, parameters can be adjusted and a new
program (scheme) and updated firmware can be downloaded remotely from the Neon
Server.
1.5
The NRL Message Based Implementation- LoRa LPWAN & Satellite Services
There are communications services available which provide a short message service,
similar to an SMS text message service.
The NRL supports LoRa LPWAN, Iridium Short Burst Data service and also other
emerging message based services. These services are in general terms message only
services, where a message is sent from the NRL to the Neon Server without
acknowledgement, without the ability to reconfigure NRL on line and without the ability to
download programs (schemes). These message based services are generally lower cost
and they suit low data rate applications very well and are less expensive.
