need more information or would like to order an antenna.
RF Exposure
To satisfy FCC RF exposure requirements for mobile transmitting
devices, a separation distance of 20 cm or more should be
maintained between the antenna of this device and persons during
device operation. To ensure compliance, operations at closer
than this distance is not recommended. The antenna used for this
transmitter must not be co-located in conjunction with any other
antenna or transmitter.
MAXIMUM EIRP
FCC Regulations allow up to 36 dBm effective isotropic radiated
power (EIRP). Therefore, the sum of the transmitted power (in
dBm), the cabling loss and the antenna gain (in dBi) cannot exceed
36 dBm.
Australian Compliance Notices
MAXIMUM EIRP
ACMA Regulations allow up to 30 dBm (1 Watt) of effective
isotropic radiated power (EIRP) in the 915MHz license free band
and 36 dBm (4 Watts) of EIRP in the 2.4GHz band. Therefore, the
sum of the transmitted power (in dBm), the cabling loss and the
antenna gain cannot exceed the above stated EIRP limits.

Part C – Applications
Part C – Applications
Generic Connectivity
The O Series has been designed for SCADA and telemetry
applications, and any other applications that use an ASCII
communications protocol, and which connect physically using the
RS-232 or RS-485 interface standard.
Any protocol that can be displayed using a PC based terminal
program operating via a serial communications port is suitable for
transmission by the O Series radio modems.
An ASCII protocol is any that consists of message strings formed
from ASCII characters, that being defined as a 10 or 11 bit block
including start and stop bits, 7 or 8 data bits and optional parity
bit(s). Port set-up dialogue that includes the expressions “N,8,1”, or
E,7,2” or similar indicate an ASCII protocol.
Most of the dominant telemetry industry suppliers utilise proprietary
ASCII protocols, and also common “open standard” industry
protocols such as DNP3, MODBUS, TCP/IP, and PPP. These are
all ASCII based protocols.
Industries and Applications
The O Series products are widely used in point-to-point and
point-to-multipoint (multiple access) applications for remote
interconnection of PLCs, RTUs, dataloggers, and other data
monitoring and control devices - including specialist utility devices
(such as powerline ACRs). In addition, other applications such as
area wide security and alarm systems, public information systems
(traffic flow and public signage systems) and environmental
monitoring systems.
Application Detail
SCADA Systems
This is where one or more centralised control sites are used
to monitor and control remote field devices over wide areas.
Examples include regional utilities monitoring and controlling
networks over entire councils or a greater city metropolis. Industry
sectors include energy utilities (gas and electricity distribution),
water and waste water utilities, catchment and environment groups
(rivers, dams and catchment management authorities).
Telemetry Systems
Dedicated telemetry control systems interconnecting sequential
devices either where cabling is not practical or distances are
considerable.
Examples include:
• ore conveyor or slurry pipeline systems
• simple water systems (pump and reservoir interlinking)
• broadcast industry (linking studio to transmitter) etc.
Information Systems
Public Information systems such as freeway vehicle flow, travel
time monitoring, feedback signage, parking signage systems and
meteorological stations etc.

O Series Data Radio – User Manual
Part D – System Planning and Design
Part E – System Planning and Design
Understanding RF Path
Requirements
A radio modem needs a minimum amount of received RF signal to
operate reliably and provide adequate data throughput.
In most cases, spectrum regulatory authorities will also define
or limit the amount of signal that can be transmitted, and the
transmitted power will decay with distance and other factors, as it
moves away from the transmitting antenna.
It follows, therefore, that for a given transmission level, there will
be a finite distance at which a receiver can operate reliably with
respect to the transmitter.
Apart from signal loss due to distance, other factors that will decay
a signal include obstructions (hills, buildings, foliage), horizon
(effectively the bulge between two points on the earth), and factors
such as fog, heavy rain-bursts, dust storms, etc.
In order to ascertain the available RF coverage from a transmitting
station, it will be necessary to consider these factors. This can be
done in a number of ways, including
(a) using basic formulas to calculate the theoretically available
signal - allowing only for free space loss due to distance,
(b) using sophisticated software to build earth terrain models
and apply other correction factors such as earth curvature
and the effects of obstructions, and
(c) by actual field strength testing.
It is good design practice to consider the results of at least two of
these models to design a radio path.
Examples of Predictive Path
Modelling
Clear line of site
Radio path with good signal levels, attenuated only by free space
loss.
Obstructed Radio Path
This path has an obstruction that will seriously degrade the signal
arriving at the field site.
