The RFI 595F is a high-speed radio modem capable of functioning
in hostile RF environments with data throughput of 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.
Also, the radio modem supports many industry standard communications protocols
with routing tables and packet timers.
