RE400 is the “easiest” radio modem in RACOM product range. It gets very close to true Plug-and-play device, as close as ever possible in private radio networks. The minimum settings necessary are all accessible from one simple web browser screen.

RE400 works as a standard IP network bridge, i.e. it is fully transparent. Every unit can serve as the central master or as a remote terminal and it can also simultaneously operate as a repeater.

The modern digital solution of the radio part (Software Defined Radio) of the RE400 radio modem allows for a wide frequency range a SW configurable channel spacing.



 

 

Features


Fully transparent

  • Standard IP network bridge functionality is implemented in the RE400 radio
    modem, i.e. the ETH interfaces of all the radiomodems in a network are
    interconnected according to bridge principles. When a COM interface is used, every
    frame received over a COM is simply broadcast to the COM interfaces of all units in
    the network.

Easy to configure and maintain
  • Web interface
  • All configuration parameters within one page
  • Basic IP knowledge is sufficient
  • CLI via SSH


Security

  • Licensed radio bands
  • FEC, interleaving, proprietary data compression
  • CRC32 data integrity control on Radio channel
  • Password-protected access, https web interface


Coverage

  • 400 MHz band
  • Line of sight is not required
  • Carrier output power adjustable 0,5 or 2W
  • Exceptional data sensitivity
  • High resistance to multipath propagation and interference
  • Any unit can work simultaneously as a repeater


Reliability

  • Every single unit tested in a climatic chamber as well as in real traffic
  • Military or industrial components
  • Industrial rugged die-cast aluminum case


Others

  • Local and remote diagnostics
  • DIN rail mounting
  • L-bracket, flat-bracket, direct mounting
  • CE approval

Applications

  • Polling type networks
  • Water
  • Oil & Gas
  • Electricity
  • Smart grid
  • POS & ATM
  • Lottery
  • Weather
  • References

Note: Since RE400 is fully transparent, it should not be used in applications which would generate collision-type traffic, e.g. in report-by-exception SCADA systems. The RE400 is suitable for master slave (polling type) applications where a single communication centre controls the communication flow.

Configuration & diagnostics

Management of RE400 radio modems is very simple and straightforward. It is done using any www browser connected via the Ethernet interface. Even remote radio modem units can be configured, however the response speed is limited by the data rate of the radio network – 10.4 kbps.

The Received Signal Strength and Data Quality information is available for individual radio connections. The pingtool can be used to diagnose a particular radio hop as well.

The complete configuration of a radio modem can be saved in a file and edited
offline in the same web interface. The stored configuration file can be
uploaded to any radio modem, making maintenance tasks very quick and simple.
