Part C – Applications
Part C – Applications
Generic Connectivity
The E 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
RS232 interface standard (although converters can be used to
adapt other interfaces such as RS422/485, RS530/V35, G703 etc).
Any protocol that can be displayed using a PC based terminal
program operating via a serial communications port is suitable for
transmission by the E 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 dialog 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 E 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

Systems Architecture
Point-to-Point
This simple system architecture provides a virtual connection
between the two points, similar to a cable. Dependent of the
hardware chosen, it is possible to provide a full duplex connection
(i.e. data transfer in both directions simultaneously) if required.
Point-to-Multipoint Systems
In a multiple access radio system, messages can be broadcast
from one (master) site to all others, either using a half duplex radio
system or from any site to all others, using a simplex radio channel.
Half duplex systems often utilise a full duplex master, to make the
system simpler and for faster operation.
In either case, it will be necessary for the application to support
an addressing system, since
the master needs to be able
to select which remote device
it with which it wishes to
communicate. Normally, the radio
system is allowed to operate
“transparently”, allowing the
application’s protocol to provide
the addressing, and thus control
the traffic. Where the application
layer does not provide the
addressing, the E Series can
provide it using SID codes™.

(See Part F - Operational Features)
Digipeater Systems
This configuration is used where all sites are required to
communicate via a repeater site. A repeater site is used because it
has a position and/or height advantage and thus provides superior
or extended RF coverage. The radio modem at the repeater does
not have to be physically connected to the application’s master
site. Information from the application’s master is transmitted to the
repeater via radio, and the repeater then relays this information
to the other field sites. In this scenario, the repeater is the master
from an RF point of view, and the application master is effectively a
“remote” from an RF point of view, even though it is controlling the
data transfer on the system.
Backbone Store and Forward Systems
Store and forward is used as a way of extending RF coverage by
repeating data messages from one site to another.
This can be done globally using the inbuilt data repeating functions,
or selectively using intelligent address based routing features
available in some PLC/RTU protocols.
In this case it is necessary for all units on the system to operate

Selecting Antennas
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 (to
a minimal extent at UHF frequencies) 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.

Part D – System Planning and Design
By compressing the transmission energy into a disc or beam, the
antenna provides more energy (a stronger signal) in that direction,
and thus is said to have a performance “gain” over a basic omni
antenna. Gain is usually expressed in dBd, which is referenced
to a standard folded dipole. Gain can also be expressed in dBi,
which is referenced to a theoretical “isotropic” radiator. Either way,
if you intend to send and receive signals from a single direction,
there is advantage in using a directional antenna - both due to
the increased signal in the wanted direction, and the relatively
decreased signal in the unwanted direction (i.e. “interference
rejection” properties).
Tuning the Antenna
Many antennas are manufactured for use over a wide frequency
range. Typical fixed use antennas such as folded dipoles and yagis
are generally supplied with the quoted gain available over the
entire specified band range, and do not require tuning. Co-linear
antennas are normally built to a specific frequency specified when
ordering.
With mobile “whip” type antennas, it is sometimes necessary
to “tune” the antenna for the best performance on the required
frequency. This is usually done by trimming an antenna element
whilst measuring VSWR, or simply trimming to a manufacturer
supplied chart showing length vs frequency. These antennas would
normally be supplied with the tuning information provided.
Antenna Placement
When mounting the antenna, it is necessary to consider the
following criteria:
The mounting structure will need to be solid enough to withstand
additional loading on the antenna mount due to extreme wind, ice
or snow (and in some cases, large birds).
For omni directional antennas, it is necessary to consider the
effect of the mounting structure (tower mast or building) on the
radiation pattern. Close in structures, particularly steel structures,
can alter the radiation pattern of the antenna. Where possible,
omni antennas should always be mounted on the top of the mast
or pole to minimise this effect. If this is not possible, mount the
antenna on a horizontal outrigger to get it at least 1-2m away from
the structure. When mounting on buildings, a small mast or pole
(2-4m) can significantly improve the radiation pattern by providing
clearance from the building structure.
For directional antennas, it is generally only necessary to consider
the structure in relation to the forward radiation pattern of the
antenna, unless the structure is metallic, and of a solid nature.
In this case it is also prudent to position the antenna as far away
from the structure as is practical. With directional antennas, it is
also necessary to ensure that the antenna cannot move in such
a way that the directional beamwidth will be affected. For long
yagi antennas, it is often necessary to install a fibreglass strut to
stablilise the antenna under windy conditions.
Alignment of Directional Antennas
This is generally performed by altering the alignment of the
antenna whilst measuring the received signal strength. If the signal
is weak, it may be necessary to pre-align the antenna using a
compass, GPS, or visual or map guidance in order to “find” the
wanted signal. Yagi antennas have a number of lower gain “lobes”
centred around the primary lobe. When aligning for best signal
strength, it is important to scan the antenna through at least 90
degrees, to ensure that the centre (strongest) lobe is identified.
When aligning a directional antenna, avoid placing your hands or
body in the vicinity of the radiating element or the forward beam
pattern, as this will affect the performance of the antenna.
There are basically two types of antennas – omni-directional and
directional.
Omnidirectional antennas are designed to radiate signal in a 360
degrees segment around the antenna. Basic short range antennas
such as folded dipoles and ground independent whips are used
to radiate the signal in a “ball” shaped pattern. High gain omni
antennas such as the “co-linear” compress the sphere of energy
into the horizontal plane, providing a relatively flat “disc” shaped
pattern which goes further because all of the energy is radiated in
the horizontal plane.
Directional antennas are designed to concentrate the signal into
“beam” of energy for transmission in a single direction (i.e. for
point-to-point or remote to base applications).
Beamwidths vary according to the antenna type, and so can be
selected to suit design requirements. The most common UHF
directional antenna is the yagi, which offers useable beam widths
of 30-50 degrees. Even higher “gain” is available using parabolic
“dish” type antennas such as gridpacks.

Data Connectivity
The V24 Standard
The E Series radio modems provide two asynchronous V24
compliant RS232 ports for connection to serial data devices.
There are two types of RS232 interfaces – DTE and DCE.
DTE stands for data terminal equipment and is generally applied to
any intelligent device that has a need to communicate to another
device via RS232. For example: P.C. Comm ports are always DTE,
as are most PLC and RTU serial ports.
DCE stands for data communication equipment and is generally
applied to a device used for sending data over some medium
(wires, radio, fibre etc), i.e. any MODEM.
The standard interface between a DTE and DCE device (using
the same connector type) is a straight through cable (i.e. each pin
connects to the same numbered corresponding pin at the other
end of the cable).
The “V24” definition originally specified the DB25 connector
standard, but this has been complicated by the emergence of the
DB9 (pseudo) standard for asynch devices, and this connector
standard has different pin assignments.
The wiring standard is “unbalanced”, and provides for three basic
data transfer wires (TXD, RXD, and SG – signal ground).
Hardware Handshaking
Hardware handshake lines are also employed to provide flow
control, however (in the telemetry industry) many devices do not
always support all (or any) flow control lines.
For this reason, the E Series modems can be configured for full
hardware flow control, or no flow control at all (simple 3 wire
interface).
Note: that when connecting devices together with differing
handshake implementations, it is sometimes necessary to
“loop” handshake pins in order to fool the devices handshaking
requirements.
In telemetry applications (particularly where port speeds can
be set to the same rate as the radio systems over-air rate)
then flow control, and therefore handshaking, is usually NOT
required. It follows that any devices that CAN be configured for
“no flow control” should be used in this mode to simplify cabling
requirements.
Handshaking lines can generally be looped as follows:
DTE (terminal) – loop RTS to CTS, and DTR to DSR and DCE.
DCE (modem) - loop DSR to DTR and RTS (note-not required for
E Series modem when set for no handshaking).
RF Feeders and Protection
The antenna is connected to the radio modem by way of an
RF feeder. In choosing the feeder type, one must compromise
between the loss caused by the feeder, and the cost, flexibility, and
bulk of lower loss feeders. To do this, it is often prudent to perform
path analysis first, in order to determine how much “spare” signal
can be allowed to be lost in the feeder. The feeder is also a critical
part of the lightning protection system.
All elevated antennas may be exposed to induced or direct
lightning strikes, and correct grounding of the feeder and mast are
an essential part of this process. Gas discharge lightning arresters
should also be fitted to all sites.
Note: All ETSI installations require the use of a lightning surge
arrestor in order to meet EN6095. See Part A - Preface for lightning
arrestor specifications.

Power Supply and Environmental
Considerations
General
When mounting the equipment, consideration should be given
to the environmental aspects of the site. The cabinet should be
positioned so that it is shaded from hot afternoon sun, or icy
cold wind. Whilst the radios are designed for harsh temperature
extremes, they will give a longer service life if operated in a more
stable temperature environment. In an industrial environment, the
radio modems should be isolated from excessive vibration, which
can destroy electronic components, joints, and crystals.
The cabinet should provide full protection from moisture, dust,
corrosive atmospheres, and residues from ants and small vermin
(which can be corrosive or conductive). The radio modem
will radiate heat from the in-built heatsink, and the higher the
transmitter duty cycle, the more heat will be radiated from the
heatsink. Ensure there is sufficient ventilation in the form of passive
or forced air circulation to ensure that the radio is able to maintain
quoted temperature limits.
Power Supply
The power supply should provide a clean, filtered DC source.
The radio modem is designed and calibrated to operate from
a 13.8VDC regulated supply, but will operate from 10-16 volts
(filtered) DC.
The power supply must be able to supply sufficient current to
provide clean filtered DC under the full current conditions of the
radio modem (i.e. when transmitting full RF power). See Section L
- Specifications for more details of the power supply requirements.
Solar Applications
In solar or battery-backed installations, a battery management unit
should be fitted to cut off power to the radio when battery levels
fall below the minimum voltage specification of the radio. In solar
applications, a solar regulation unit MUST ALSO be fitted to ensure
that the radio (and battery) is protected from excessive voltage
under full sun conditions.
When calculating solar and battery capacity requirements, the
constant current consumption will be approximately equal to the
transmit current multiplied by the duty cycle of the transmitter, plus
the receive current multiplied by the (remaining) duty cycle of the
receiver.
The Tx/Rx duty cycle will be entirely dependent on the amount
of data being transmitted by the radio modem, unless the device
has been configured for continuous transmit, in which case the
constant current consumption will be equal to the transmit current
only (at 100% duty cycle).
Note: Operation below the minimum specified supply voltages
could result in poor radio performance. If the supply voltage falls
below 7.2Vdc the radio will shut down. Normal radio startup will not
occur until 10Vdc is supplied.
Site Earthing
The radio must not be allowed to provide a ground path from
chassis to (DB9) signal ground or (-) battery ground. Ensure that
the chassis mounting plate, power supply (-) earth, RTU terminal
device, and lightning arrester, are all securely earthed to a common
ground point to which an earth stake is attached. Please pay
particular attention to 24Vdc PLC systems using DC-DC converters
to supply 13.8Vdc.
Caution: There is NO readily serviceable internal fuse,
and therefore the radio modem MUST be externally fused
with a fuse and fuse holder (ER450: 3 amp fast-blow fuse,
EB450: 5 amp fast-blow fuse).

ER450 Quick Start Guide
Introduction
Welcome to the ER450 Quick Start Guide. This guide provides
step-by-step instructions, with simple explanations to get you up-
and-running.
Mounting and Environmental
Considerations
The ER450 radio comes complete with a mounting cradle and is
attached to a panel or tray by means of screws or bolts, using the
hole slots provided.
Note: In high power or high temperature applications, it is desirable
to mount the radio with the heatsink uppermost to allow ventilation
for the heatsink.
The radio should be mounted in a clean and dry location,
protected from water, excessive dust, corrosive fumes, extremes
of temperature and direct sunlight. Please allow sufficient passive
or active ventilation to allow the radio modem’s heatsink to operate
efficiently.

ER450 Connections Layout
Connecting Antennas and RF Feeders
The RF antenna system should be installed in accordance with the
manufacturers notes.
The RF connector used on the E Series radios are N Type female
connectors. Always use good quality low loss feeder cable,
selected according to the length of the cable run. Ensure all
external connections are waterproofed using amalgamating tape.
Preset directional antennas in the required direction using a
compass, GPS, or visual alignment and ensure correct polarisation
(vertical or horizontal).
Communications Ports
System Port – RJ45
The System Port (available front and rear on EB/EH450) is a multi-
function interface used for:
• Programming / Configuration of the radio
• Remote Diagnostics connections
To access these functions use theTVIEW+ Cable assembly (RJ45
Cable and RJ45 to DB9 Adaptor).
The TVIEW+ Cable is a standard CAT 5 RJ-45 (Male) to RJ-45
(Male) patch cable. It is intented for RS232 serial communications
only and should not be connected directly into an ethernet port
of a PC. The Cable must be used in conjunction with the RJ-45 to
DB9 Adaptor.
TVIEW+ Adaptor Configuration:
Special user pinouts:
• Shutdown (Pin 4) - Active low for power save function
• External PTT (Pin 8) - Provides a manual PTT override
facility for enabling the transmitter. For testing this can be
activated by connecting PTT (Pin 8 ) to Gnd (Pin 7).

Part E – Getting Started - ER450
User Interfaces – Ports A & B
Each user port (A & B) is wired as a RS232 DCE, configurable for
no handshaking (3-wire) interface, or for hardware or software (X-
on/X-off) flow control. In most systems flow control is not required,
in which case only 3 wires need to be connected between the radio
and the application device.
Typical pins used:
• Pin 2 (RxD) - data output from the radio modem,
• Pin 3 (TxD) - data input to the radio modem,
• Pin 5 (SG) - signal ground.
See Part D – System Planning and Design - Data Connectivity, for
further details of other cable configurations.
RS232 Connector Pin outs (DCE)
Port A and B, Female DB9
Activating the Transmitter
In most systems, the transmitter by default is controlled
automatically by the radio when it has data to transmit.
In some systems, such as full duplex point-to-point links or full
duplex point-to-multipoint base stations, it is desirable to run the
transmitter all the time (hot keyed).
Two mechanisms are provided to do this:
• the radio modem can be configured to transmit continuously
whenever powered, or
• the radio modem can be configured to transmit whenever an
external RTS signal (Pin 7) is applied to one (or either) user
ports. (To simulate an external RTS input, loop pins 6 to 7).
To operate in these modes, the radio must be configured via the
programming software.
Caution: When the radio is configured to transmit
continuously, ensure an RF load is present BEFORE
applying power to the unit.

Power Supply Requirements
The E Series radio modem is designed and calibrated to operate
from a filtered 13.8Vdc regulated supply, but will operate from a
10-16Vdc (11-16Vdc for EB450 & EH450) range. See Section L
- Specifications for more details on power supply requirements
Caution: There is NO readily serviceable internal fuse,
and therefore the radio modem MUST be externally fused
with a fuse and fuse holder (ER450: 3 amp fast-blow fuse,
EB450: 5 amp fast-blow fuse).
The radio is designed to self protect from permanent damage if the
voltage exceeds 16Vdc or if reverse polarity is applied. The radio
may need to be returned for service if this occurs.
The radio modem can also be damaged if there is any potential
difference between the chassis-ground, RS232 signal ground,
power (-) input, or antenna coaxial shield. Before connecting any
wiring, ensure all components are earthed to a common ground
point (please pay particular attention to 24V PLC power systems
where converters are used).
Connect the antenna and RS 232 plugs BEFORE applying power
to the unit.
Lastly, before inserting the power plug, please re-check that
the polarity and voltage on the power plug is correct using a
multimeter.
TVIEW+ Management Suite
Radio Configuration
This TVIEW+ Management Suite allows a number of features
including: Configuration (Local - serial, or Remote - over-the-air),
Remote Diagnostics Facilities and Firmware Upgrades.
The configuration wizard can be used to provide Quick Start

Optimising the Antenna for best RX
signal
Once the unit is operational, it is important to optimise the antenna
tuning.
In the case of a directional antenna, it will be necessary to align the
antenna for the best received signal.
This can be done by using the (0-5Vdc) output on Pin 9 of Port B
to indicate signal strength (RSSI). This voltage can be converted to
dBm using the chart below.
LED Indicators & Test Outputs
Radio is Powered
If all the LEDs are off, no power is reaching the radio modem.
Successful power-up is indicated by the “PWR” LED indicating a
continuous (healthy) GREEN state. Note that this LED is turned
RED when the transmitter is active.
LED Legend
Part E – Getting Started- ER450
Radio Errors
Internal radio management software monitors many aspects of
the radio hardware. Under certain circumstances radio faults may
prevent normal operation. In the event that these fault conditions
occur, the radio will enter an ERROR state and this will be
indicated by flashing ALL LEDs RED, then flashing a pattern of
GREEN LEDs. The pattern of all GREEN LEDs represents the
specific type of error that has occurred. See Table below.
All other patterns indicate serious hardware errors. Please record
this pattern and return the result with the service return information.
Note (1): If external voltage is too high (>16Vdc) radio damage
may occur. If the external voltage is too low (<10Vdc) the radio
may not operate within specifications.
Note (2) and (3): If the radio receiver or transmitter frequencies
are programmed outside the specified frequency ranges (model
type dependent), then normal radio operation may not be possible.
In this case, use TVIEW+ to set the receiver and/or transmitter
frequencies to be within the specified range. If this error occurs and
the frequencies are within the specified frequency ranges (model
type dependent), the radio will need to be returned for service.

Received Signal Indicator
The “RX/SYNC” LED is used to indicate the state of the receiver.
If the LED is off, no signal is being received.
A RED indication shows that an RF carrier is being received, but
no data stream can be decoded. This will briefly happen at the
very start of every valid received transmission or may indicate the
presence of interference, or another user on the channel.
A continuous GREEN indication shows that the modem is locked
and synchronised to the incoming signal, and has excellent Bit
Error Rate (BER). Any losses of synchronisation (BER errors) are
shown as a visible RED flicker of the LED.
Note: This might only be apparent on a PTMP slave when only
receiving.
Verifying Operational Health
It is possible to verify the operation of the radio modem using the
indicators provided by the unit. The state of the transmitter and
receiver, and data flow can be interpreted by the indicator LEDs
(see below).
Note: Port A and Port B’s RxD and TxD will be Active on Data Flow
Data Flow “breakout” LEDs
There are also two LEDs to indicate data flow into and out of the
two user ports.
Input data to be transmitted is shown as a RED flash, and received
data to be output to the port is shown as a GREEN flash.
If data is alternately flowing in and out quickly, then the indicator
appears orange.

EB450 Quick Start Guide
Introduction
Welcome to the Quick Start Guide for the EB450 Base / Repeater
Data Radio. This guide provides step-by-step instructions, with
simple explanations to get you up-and-running.
Mounting and Environmental
Considerations
The EB450 Base Station is housed in a 2RU 19” rack enclosure.
The 4 mounting holes on the front panel should be used to secure
the unit to the rack.
The radio should be mounted in a clean and dry location,
protected from water, excessive dust, corrosive fumes, extremes
of temperature and direct sunlight. Please allow sufficient passive
or active ventilation to allow the radio modem’s heatsink to operate
efficiently.
All permanent connections are made at the rear of the unit. This
includes: Power, Antenna, Communications Ports, Digital I/O
and System Port. The front panel has an additional System Port
connection point for easy access.
Full Duplex Considerations
The EB450 is designed for continuous full duplex transmission. An
automatic thermostatically controlled fan will operate whenever the
internal temperature exceeds 50 degrees Celsius.
External Duplexer Considerations
The EB450 is normally supplied with separate Tx and Rx ports for
connection to an external duplexing system.
Depending on the frequency band of operation and the Tx/Rx
frequency split, internal band reject duplexers are available.
