Radio Modems

General purpose radio data modems for various applications

STI Radio Modems

STI’s sophisticated RF spread-spectrum radios give error free transmission even in areas of high interference.

The STI radio modem range includes “Licenced” and “Licence free” radio modems. This refers to the need for a radio licence in Australia to operate the radios:

  • Licence free radio modems use the public ISM bands, which do not require a licence to operate in.
  • Licenced radios use radio bands that are restricted and require a licence to be obtained from ACMA before they can be used.

Cruise Control Software Makes it Easy

The STI Cruise Control configuration and diagnostics software makes it easier to set-up and maintain your radio networks.

– One-click connectioncruise_control
– Load/Save Function
– Real-time diagnostics
– Remote Radio Diagnostics
– Expandable folder view with compete configuration options
– Email your files to STI for technical support

 

Licence Free Radio Modems for Data Transfer – 900MHz & 433MHz

This excellent range of radio modems has many advanced features such as frequency hopping, error corrections, protocol routing for Modbus RTU, DNP 3 etc protocols.

Another useful feature of these devices are that they can emulate a standard Hayes modem, except that you are using radio rather than telephone lines. In this mode, it supports most Hayes AT commands.

In addition to this, they support many different network configurations such as point-to-point, point-to-multipoint and back-to-back repeater modes.

Minimise Machinery Downtime with RFI-Minelink

Operational downtime can cost mining companies millions of dollars in lost production every day.

To counter this potentially costly problem, the RFI-Minelink system has been developed to download vehicle operational data from Caterpillar™ trucks in open-pit mines.

Utilising a specialised version of the RFI-9256 modem, the system permits real-time monitoring of mining vehicles, allowing for implementation of pro-active maintenance strategies to minimise the possibility of machine failure.

Self-contained portable repeater stations ensure optimal coverage, even in the constantly changing environments of mine sites.

The flexibility of the RFI-Minelink system makes it suitable for very large areas and for pockets of interest within a mine site.

RFI-9256 Makes its Mark on Security

The RF Innovations RFI-9256 radio modem has been successfully utilised in security access control systems across a range of applications, including tracking of mining personnel, transitory gates at mine sites and in hospital car parks.

The radio modem is particularly well suited for use in mobile and temporary access point applications, or as an alternative where cabling is either uneconomical or impractical.

The versatility of the RFI-9256 makes it suitable for a wide array of purposes, and the radio is fully compatible with the software of industry leaders Siemens™, Honeywell™ and Tecom™.

The RFI 595F is a high-speed radio modem (not spread spectrum) capable of functioning in hostile RF environments.
RS232 data throughput is 9600 bps.
Intelligent integrated software allows many different data configurations,
including store and forward repeater operation and intelligent protocol routing for large SCADA systems.
Built in path testing  –  In built in diagnostics  –  Front panel indicators  –  Up to 50 km in one hop  –  Forward error correction
Can be commissioned without test equipment

It can interface with virtually any standard Data logger, PLC, computer; i.e. any RS232 device.
In built buffers handshake with input/output devices at data speeds up to 38400 bps and transparently move data to the other end.
Depending upon the geography and terrain, the Radio modems can communicate reliably over considerable distances.
Good line of site paths from mountaintop to hill can extend useful range beyond 100 km.
In any event, repeater facility permits extension of useful range when clear line-of-site paths are not available.

Software options include store and forward repeater function, which permits remote hilltop repeater applications.
There is no progressive degradation of Signal to Noise Ratio as the repeater function brings the signal back to digital base band.
