This USB device connects to the USB port of a PC and communicates with all Newsteo radio dataloggers.

  • RF-to-USB key is delivered with Windows drivers
  • Once driver first installed, the RF-to-USB key behaves as a plug’n’play standard removable device
  • USB 1.1 high speed (USB 2.0 host compatible)
  • The RF-to-USB key is marketed with the measurement display software: the RF Monitor software
  • Powered by PC (no internal battery)

Ethernet or GPRS collector: the gateway between the radio loggers and a database on your network
The  Newsteo Collector allows remote collection, through Ethernet (IP) or  GPRS (GSM network), of data coming from several Newsteo loggers, and  storage on a remote secured server.
The Newsteo Collector exists in several versions, for indoor or outdoor uses, with a main power supply or solar panels supply.
Remote monitoring
Avoid the coming of operator on site
Multi-sites
Several remote sites connected by several gateways

Real time alert
Send an email or a SMS as soon as a measurement is outside of normal thresholds
Webmonitor Application
Web application for measurements displaying

Always informed
Cloud computing give you the broader access to your data, this technology enables you a perfect follow-up of your data loggers everywhere, and at every hour over the Internet, by simply using a pc, a smartphone or a tablet.

Solutions to increase the system's RF range.

Communication between Newsteo radio products and reception center (PC  with RF-to-USB key) can sometimes be perturbed by obstacle or too high  distance. ach.
To improve the transmission between loggers, pc and webmonitor, we can propose you different solutions :
- repeater : they will be installed mid-way, acting as radio relay for all products out of radio reach ;
- or a  choice of antennas.
Newsteo Radio Protocol: No Lost Measurement
Your precious data are secured with our Central Monitoring System.

We are aware of the importance of your measurements.
For all the companies we are working with, this is the key need.
Temperature monitoring during blood transportation, humidity in pharmaceutical laboratories, current measurement of an engine ... we ensure in all our products the back-up of your measurements (unlike many competing solutions ... ).

• Each time a radio recorder sends its measurement, it waits for an acknowledgment of the receiver. If it does not receive the acknowledgment, it tries again 2 times to transmit its measurement.
• If the measurement could not be transmitted, the recorder stores it and tries to transmit it one minute later.
• In all cases, whether transmitted or not, the recorder keeps the last 32,000 measurements in its internal memory, thus ensuring a local backup of the data.



RF Monitor Premium : the convenient powerful MMI tool

The Newsteo RF Monitor gives the opportunity to remotely configure and control the distant wireless Newsteo products.

Software versions:
  • RF Monitor Premium: for single-site installations. The loggers communicate to a PC, the measurements are displayed only on this PC.
  • RF Monitor Gold: for multi-site installations. Several Loggers networks are created. Each system communicates to a PC that transmits the measurement to a central database. From anywhere in the world, it is possible to connect to the database to check the measurements. This consultation is possible with free software DB Monitor.
  • CFR 21 part 11 option: available either on the Premium or Gold version, the CFR option adds a module for a complete tracking of each action done on the software.

    • 4GB Database
    • Several collectors may send their measurements to a single database. Therefore, only one subscription is necessary
    2. The user accesses when he wants to measurements:
  • Access to measurements can be performed using DB Monitor software provided by Newsteo or by using the web supervision application: Webmonitor, available on the internet.
    • Access 24 hours on 24, 7 days on 7 to the loggers measurements
    • Secured access, ID and password required
  • 3. The platform can send alerts or reports:
    • Using Webmonitor:
      Immediate email alerts when threshold is exceeded on a logger
      Sending of a PDF report each week, including all measures and alerts detected by the logger
    • Using the DB Monitor software: immediate alerts by email when a threshold is exceeded in a logger
    4. Management of the platform by Newsteo:
    • Database backups made by Newsteo
    • Once a year, sending of a DVD including all measurements of the year
    Test the web monitor application :
  • Connect to the website www.newsteo-webmonitor.com
  • Enter the database : client
  • Enter the password : client
  • That is, measurements of that user’s data loggers are displayed
  • Here under display of the webmonitor
