Page 10E Series Data Radio  User Manual© Copyright 2004 Trio DataCom Pty. Ltd.Part C  ApplicationsPart C  ApplicationsGeneric ConnectivityThe E Series has been designed for SCADA and telemetryapplications, and any other applications that use an ASCIIcommunications protocol, and which connect physically using theRS232 interface standard (although converters can be used to adaptother interfaces such as RS422/485, RS530/V35, G703 etc).Any protocol that can be displayed using a PC based terminalprogram operating via a serial communications port is suitable fortransmission by the E Series radio modems.An ASCII protocol is any that consists of message strings formedfrom ASCII characters, that being defined as a 10 or 11 bit blockincluding 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 orsimilar indicate an ASCII protocol.Most of the dominant telemetry industry suppliers utilise proprietaryASCII protocols, and also common 'open standard industry protocolssuch as DNP3, MODBUS, TCP/IP, and PPP. These are all ASCIIbased protocols.Industries and ApplicationsThe E Series products are widely used in point-to-point and point-to-multipoint (multiple access) applications for remote interconnection ofPLCs, RTUs, dataloggers, and other data monitoring and controldevices - including specialist utility devices (such as powerlineACRs). In addition, other applications such as area wide security andalarm systems, public information systems (traffic flow and publicsignage systems) and environmental monitoring systems.Application DetailSCADA SystemsThis is where one or more centralised control sites are used to monitorand control remote field devices over wide areas. Examples includeregional utilities monitoring and controlling networks over entire shiresor a greater city metropolis. Industry sectors include energy utilities(gas and electricity distribution), water and sewerage utilities,catchment and environment groups (rivers, dams and catchmentmanagement authorities).Telemetry SystemsDedicated telemetry control systems interconnecting sequentialdevices either where cabling is not practical or distances areconsiderable.Examples include: ore conveyor or slurry pipeline systems simple water systems (pump and reservoir interlinking) broadcast industry (linking studio to transmitter) etc.Information SystemsPublic Information systems such as freeway vehicle flow, travel timemonitoring, feedback signage, parking signage systems andmeteorological stations etc.
Page 11E Series Data Radio  User Manual © Copyright 2004 Trio DataCom Pty. Ltd.Part C  ApplicationsSystems ArchitecturePoint-to-PointThis simple system architecture provides a virtual connection betweenthe two points, similar to a cable. Dependent of the hardware chosen,it is possible to provide a full duplex connection (i.e. data transfer inboth directions simultaneously) if required.Point-to-Multipoint SystemsIn a multiple access radio system, messages can be broadcast fromone (master) site to all others, either using a half duplex radio systemor from any site to all others, using a simplex radio channel.Half duplex systems often utilise a full duplex master, to make thesystem simpler and for faster operation.In either case, it will be necessary for the application to support anaddressing system, since themaster needs to be able to selectwhich remote device it with whichit wishes to communicate.Normally, the radio system isallowed to operate transparently,allowing the applications protocol toprovide the addressing, and thuscontrol the traffic. Where theapplication layer does not providethe addressing, the E Series canprovide it using SID codes. (SeePart F - Operational Features)
Page 12E Series Data Radio  User Manual© Copyright 2004 Trio DataCom Pty. Ltd.Part C  ApplicationsDigipeater SystemsThis configuration is used where all sites are required to communicatevia a repeater site. A repeater site is used because it has a positionand/or height advantage and thus provides superior or extended RFcoverage. The radio modem at the repeater does not have to bephysically connected to the applications master site. Information fromthe applications master is transmitted to the repeater via radio, and therepeater then relays this information to the other field sites. In thisscenario, the repeater is the master from an RF point of view, and theapplication 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 SystemsStore and forward is used as a way of extending RF coverage byrepeating data messages from one site to another.This can be done globally using the inbuilt data repeating functions, orselectively using intelligent address based routing features available insome PLC/RTU protocols.In this case it is necessary for all units on the system to operate in halfduplex mode (only key-up when transmitting data), so that each site isfree to hear received signals from more than one source.Digipeater SystemBackbone Store and ForwardSystem
Page 13E Series Data Radio  User Manual © Copyright 2004 Trio DataCom Pty. Ltd.Part D  System Planning and DesignPart D  System Planning and DesignUnderstanding RF PathRequirementsA radio modem needs a minimum amount of received RF signal tooperate reliably and provide adequate data throughput.In most cases, spectrum regulatory authorities will also define or limitthe amount of signal that can be transmitted, and the transmitted powerwill decay with distance and other factors, as it moves away from thetransmitting antenna.It follows, therefore, that for a given transmission level, there will be afinite distance at which a receiver can operate reliably with respect tothe transmitter.Apart from signal loss due to distance, other factors that will decay asignal include obstructions (hills, buildings, foliage), horizon (effectivelythe bulge between two points on the earth), and (to a minimal extent atUHF frequencies) factors such as fog, heavy rain-bursts, dust storms,etc.In order to ascertain the available RF coverage from a transmittingstation, it will be necessary to consider these factors. This can bedone in a number of ways, including(a) using basic formulas to calculate the theoretically availablesignal - allowing only for free space loss due to distance,(b) using sophisticated software to build earth terrain models andapply other correction factors such as earth curvature and theeffects of obstructions, and(c) by actual field strength testing.It is good design practice to consider the results of at least two of thesemodels to design a radio path.

Page 16E Series Data Radio  User Manual© Copyright 2004 Trio DataCom Pty. Ltd.Part D  System Planning and Design Antenna GainBy compressing the transmission energy into a disc or beam, theantenna provides more energy (a stronger signal) in that direction, andthus is said to have a performance gain over a basic omni antenna.Gain is usually expressed in dBd, which is referenced to a standardfolded dipole. Gain can also be expressed in dBi, which is referencedto a theoretical isotropic radiator. Either way, if you intend to sendand receive signals from a single direction, there is advantage in usinga directional antenna - both due to the increased signal in the wanteddirection, and the relatively decreased signal in the unwanted direction(i.e. interference rejection properties).Tuning the AntennaMany antennas are manufactured for use over a wide frequencyrange. Typical fixed use antennas such as folded dipoles and yagisare generally supplied with the quoted gain available over the entirespecified band range, and do not require tuning. Co-linear antennas arenormally 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 measuringVSWR, or simply trimming to a manufacturer supplied chart showinglength vs frequency. These antennas would normally be supplied withthe tuning information provided.Antenna PlacementWhen mounting the antenna, it is necessary to consider the followingcriteria:The mounting structure will need to be solid enough to withstandadditional loading on the antenna mount due to extreme wind, ice orsnow (and in some cases, large birds).For omni directional antennas, it is necessary to consider the effect ofthe mounting structure (tower mast or building) on the radiation pattern.Close in structures, particularly steel structures, can alter the radiationpattern of the antenna. Where possible, omni antennas should alwaysbe mounted on the top of the mast or pole to minimise this effect. If thisis not possible, mount the antenna on a horizontal outrigger to get it atleast 1-2m away from the structure. When mounting on buildings, asmall mast or pole (2-4m) can significantly improve the radiationpattern by providing clearance from the building structure.For directional antennas, it is generally only necessary to consider thestructure in relation to the forward radiation pattern of the antenna,unless the structure is metallic, and of a solid nature. In this case it isalso prudent to position the antenna as far away from the structure asis practical. With directional antennas, it is also necessary to ensurethat the antenna cannot move in such a way that the directionalbeamwidth will be affected. For long yagi antennas, it is oftennecessary to instal a fibreglass strut to stablilise the antenna underwindy conditions.Alignment of Directional AntennasThis is generally performed by altering the alignment of the antennawhilst measuring the received signal strength. If the signal is weak, itmay be necessary to pre-align the antenna using a compass, GPS,or visual or map guidance in order to find the wanted signal. Yagiantennas have a number of lower gain lobes centred around theprimary lobe. When aligning for best signal strength, it is important toscan 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 bodyin the vicinity of the radiating element or the forward beam pattern, asthis will affect the performance of the antenna.Selecting AntennasThere are basically two types of antennas  omni-directional anddirectional.Omnidirectional antennas are designed to radiate signal in a 360degrees segment around the antenna. Basic short range antennassuch as folded dipoles and ground independent whips are used toradiate the signal in a ball shaped pattern. High gain omni antennassuch as the co-linear compress the sphere of energy into thehorizontal plane, providing a relatively flat disc shaped pattern whichgoes further because all of the energy is radiated in the horizontalplane.Directional antennas are designed to concentrate the signal into beamof energy for transmission in a single direction (i.e. for point-to-point orremote to base applications).Beamwidths vary according to the antenna type, and so can beselected to suit design requirements. The most common UHFdirectional antenna is the yagi, which offers useable beam widths of30-50 degrees. Even higher gain is available using parabolic dishtype antennas such as gridpacks.

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 generallyapplied 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 thesame connector type) is a straight through cable (i.e. each pinconnects to the same numbered corresponding pin at the other end ofthe 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 differentpin assignments.The wiring standard is unbalanced, and provides for three basic datatransfer wires (TXD, RXD, and SG  signal ground).Hardware HandshakingHardware handshake lines are also employed to provide flow control,however (in the telemetry industry) many devices do not alwayssupport all (or any) flow control lines.For this reason, the E Series modems can be configured for fullhardware flow control, or no flow control at all (simple 3 wireinterface).Note: that when connecting devices together with differing handshakeimplementations, it is sometimes necessary to loop handshake pinsin order to fool the devices handshaking requirements.In telemetry applications (particularly where port speeds can be set tothe same rate as the radio systems over-air rate) then flow control,and therefore handshaking, is usually NOT required. It follows thatany devices that CAN be configured for no flow control should beused 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 ESeries modem when set for no handshaking).RF Feeders and ProtectionThe antenna is connected to the radio modem by way of an RF feeder.In choosing the feeder type, one must compromise between the losscaused by the feeder, and the cost, flexibility, and bulk of lower lossfeeders. To do this, it is often prudent to perform path analysis first, inorder to determine how much spare signal can be allowed to be lostin the feeder. The feeder is also a critical part of the lightning protectionsystem.All elevated antennas may be exposed to induced or direct lightningstrikes, and correct grounding of the feeder and mast are an essentialpart of this process. Gas discharge lightning arresters should also befitted to all sites.Note: All ETSI installations require the use of a lightning surgearrestor in order to meet EN6095. See Part A - Preface for lightningarrestor specifications.

Ltd.Part D  System Planning and DesignPower Supply and EnvironmentalConsiderationsGeneralWhen mounting the equipment, consideration should be given to theenvironmental aspects of the site. The cabinet should be positioned sothat it is shaded from hot afternoon sun, or icy cold wind. Whilst theradios are designed for harsh temperature extremes, they will give alonger service life if operated in a more stable temperatureenvironment. In an industrial environment, the radio modems shouldbe isolated from excessive vibration, which can destroy electroniccomponents, 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 radiateheat from the in-built heatsink, and the higher the transmitter dutycycle, the more heat will be radiated from the heatsink. Ensure there issufficient ventilation in the form of passive or forced air circulation toensure that the radio is able to maintain quoted temperature limits.Power SupplyThe power supply should provide a clean, filtered DC source. Theradio modem is designed and calibrated to operate from a 13.8VDCregulated supply, but will operate from 10-16 volts (filtered) DC.The power supply must be able to supply sufficient current to provideclean filtered DC under the full current conditions of the radio modem(i.e. when transmitting full RF power). See Section L - Specificationsfor more details of the power supply requirements.Solar ApplicationsIn solar or battery-backed installations, a battery management unitshould be fitted to cut off power to the radio when battery levels fallbelow the minimum voltage specification of the radio. In solarapplications, a solar regulation unit MUST ALSO be fitted to ensurethat the radio (and battery) is protected from excessive voltage underfull sun conditions.When calculating solar and battery capacity requirements, the constantcurrent consumption will be approximately equal to the transmit currentmultiplied by the duty cycle of the transmitter, plus the receive currentmultiplied by the (remaining) duty cycle of the receiver.The Tx/Rx duty cycle will be entirely dependent on the amount of databeing transmitted by the radio modem, unless the device has beenconfigured for continuous transmit, in which case the constant currentconsumption will be equal to the transmit current only (at 100% dutycycle).Note: Operation below the minimum specified supply voltages couldresult in poor radio performance. If the supply voltage falls below7.2Vdc the radio will shut down. Normal radio startup will not occuruntil 10Vdc is supplied.Site EarthingThe radio must not be allowed to provide a ground path from chassisto (DB9) signal ground or (-) battery ground. Ensure that the chassismounting plate, power supply (-) earth, RTU terminal device, andlightning arrester, are all securely earthed to a common ground point towhich an earth stake is attached. Please pay particular attention to24Vdc PLC systems using DC-DC converters to supply 13.8Vdc.Caution: There is NO internal replaceable fuse, and thereforethe radio modem MUST be externally fused with the fuseholder provided (ER450: 3 amp slo-blow fuse, EB450: 5amp fast-blow fuse).
