Part B – E Series Overview
Definition of E Series Data Radio
The E Series is a range of wireless modems designed for the
transmission of data communications for SCADA, telemetry
and any other information and control applications that utilise
ASCII messaging techniques. The E Series uses advanced
“digital” modulation and signal processing techniques to achieve
exceptionally high data throughput efficiency using traditional
licensed narrow band radio channels.
These products are available in many frequency band and
regulatory formats, to suit spectrum bandplans, in various
continental regions. The range is designed for both fixed point
to point (PTP), and multiple address (MAS) or point to multipoint
(PMP) systems.
E Series Product Range
The E Series range consists of the basic half duplex “Remote”
radio modem, an extended feature full duplex Remote radio
modem, and ruggedised Base Station variants, including an
optional Hot Standby controller to control two base station units in
a redundant configuration.
Frequency band variants are indicated by the band prefix and
model numbering. (See Model Number Codes)

E Series – Features and Benefits
Common Features and Benefits of the E
Series Data Radio
• Up to 19200bps over-air data rates using programmable
DSP based advanced modulation schemes.
• Designed to various International regulatory requirements
including FCC, ETSI and ACA.
• Superior receiver sensitivity.
• Fast data turnaround time <10mS.
• Flash upgrade-able firmware – insurance against
obsolescence.
• Multi-function bi-colour Tx/Rx data LEDs showing Port
activity (breakout box style), as well as LEDs indicating Tx,
Rx, RF Signal, Data Synchronisation and DC Power status
of the radio.
• Rugged N type antenna connectors on all equipment.
• High temperature transmitter foldback protection.
• Two independent configurable data ports and separate
system port.
• Higher port speeds to support increased air-rate (up to
76800bps on Port A and 38400bps on Port B).
• Independent system port for interruption free programming
and diagnostics (in addition to two (2) user ports).
• 9600bps in 12.5 kHz radio channels with ETSI
specifications.
• Remote over-the-air configuration of any radio from any
location.
• Multistream™ simultaneous data streams allows for multiple
vendor devices / protocols to be transported on the one
radio network.
• Flexible data stream routing and steering providing optimum
radio channel efficiency – complex data radio systems can
be implemented with fewer radio channels.
• The ability to duplicate data streams – that is, decode the
same off-air data to two separate ports.
• Multi-function radio capable of dropping off one stream to a
port and forward on or repeat (store and forward) the same
or other data.
• Stand-alone internal store and forward operation – buffered
store and forward operation even in the ER remote units.
• Unique integrated C/DSMA collision avoidance technology
permits simultaneous polling and spontaneous reporting
operation in the same system.
• Digital receiver frequency tracking for long term data
reliability.
