Page 8E Series Data Radio – User Manual© Copyright 2002 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 toadapt other interfaces such as RS422/485, RS530/V35, G703 etc).Any protocol that can be displayed using a PC based terminalprogram operating via a serial comm 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 paritybit(s). Port set-up dialog that includes the expressions “N,8,1”, orE,7,2” or similar indicate an ASCII protocol.Most of the dominant telemetry industry suppliers utilise proprietaryASCII protocols, and also common “open standard” industryprotocols such as DNP3, MODBUS, TCP/IP, and PPP. These areall ASCII. based protocols.Industries and ApplicationsThe E Series products are widely used in point-to-point and point-to-multipoint (multiple access) applications for remoteinterconnection of PLC’s, RTU’s, dataloggers, and other datamonitoring and control devices including specialist utility devices(such as powerline ACR’s). In addition, other applications such asarea wide security and alarm systems, public information systems(traffic flow and public signage systems) and environmentalmonitoring systems.Application DetailSCADA SystemsThis is where one or more centralised control sites are used tomonitor and control remote field devices over wide areas.Examples include regional utilities monitoring and controllingnetworks over entire shires or a greater city metropolis’. Industrysectors include energy utilities (gas and electricity distribution),water and sewerage utilities, and catchment and environmentgroups (rivers, dams, and catchment management authorities).Telemetry SystemsDedicated telemetry control systems interconnecting sequentialdevices where cabling is not practical or distances areconsiderable.Examples include ore conveyor or slurry pipeline systems, simplewater systems (pump and reservoir interlinking), broadcast industry(linking studio to transmitter) etc.Information SystemsPublic Information systems such as freeway vehicle flow and traveltime monitoring, and feedback signage, parking signage systems,meteorological stations etc.

Ltd.Part C  ApplicationsSystems ArchitecturePoint-to-PointThis simple system architecture provides a virtual connectionbetween the two points, similar to a cable. Dependant of thehardware chosen, it is possible to provide a full duplex connection(i.e. data transfer in both directions simultaneously) if required.Point-to-Multipoint SystemsIn a multiple access radio system, messages can be broadcastfrom one (master) site to all others, using a half duplex radiosystem, or from any site to all others, using a simplex radiochannel.Half duplex systems often utilise a full duplex master, to make thesystem simpler, and to operate faster.In either case, it will be necessary for the application to support anaddressing system, since the master needs to be able to selectwhich remote device it wishes to communicate to. Normally, theradio system is allowed to operate “transparently”, allowing theapplication’s protocol to provide the addressing, and thus controlthe traffic. Where the application layer does not provide theaddressing, the E Series can provide it using SID codes™. (SeePart F - Operational Features)
Page 10E Series Data Radio – User Manual© Copyright 2002 Trio DataCom Pty. Ltd.Part C  ApplicationsDigipeater SystemsThis configuration is used where all sites are required tocommunicate via a repeater site. A repeater site is used because ithas a position and/or height advantage and thus provides superioror extended RF coverage. The radio modem at the repeater doesnot have to be physically connected to the application’s mastersite. Information from the application’s master is transmitted to therepeater via radio, and the repeater then relays this information tothe other field sites. In this scenario, the repeater is the masterfrom an RF point of view, and the application master is effectively a“remote” from an RF point of view, even though it is controlling thedata transfer on the system.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 inhalf duplex mode (only key-up when transmitting data), so thateach site is free to hear received signals from more than onesource.
Page 11E Series Data Radio – User Manual © Copyright 2002 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 orlimit the amount of signal that can be transmitted, and thetransmitted power will decay with distance and other factors, as itmoves away from the transmitting antenna.It follows, therefore, that for a given transmission level, there will bea finite distance at which a receiver can operate reliably withrespect to the transmitter.Apart from signal loss due to distance, other factors that will decaya signal include obstructions (hills, buildings, foliage), horizon(effectively the bulge between two points on the earth), and (to aminimal extent at UHF frequencies) factors such as fog, heavyrain-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 theoreticallyavailable signal - allowing only for free space loss due todistance,(b) using sophisticated software to build earth terrain modelsand apply other correction factors such as earth curvatureand the effects of obstructions, and(c) by actual field strength testing.It is good design practice to consider the results of at least two ofthese models to design a radio path.

Page 14E Series Data Radio – User Manual© Copyright 2002 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,and thus is said to have a performance “gain” over a basic omniantenna. Gain is usually expressed in dBd, which is referenced toa standard folded dipole. Gain can also be expressed in dBi, whichis referenced to a theoretical “isotropic” radiator. Either way, if youintend to send and receive signals from a single direction, there isadvantage in using a directional antenna - both due to theincreased signal in the wanted direction, and the relativelydecreased signal in the unwanted direction (i.e. “interferencerejection” 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 theentire specified band range, and do not require tuning. Co-linearantennas are normally built to a specific frequency specified whenordering.With mobile “whip” type antennas, it is sometimes necessary to“tune” the antenna for the best performance on the requiredfrequency. This is usually done by trimming an antenna elementwhilst measuring VSWR, or simply trimming to a manufacturersupplied chart showing length vs frequency. These antennas wouldnormally be supplied with the tuning information provided.Antenna PlacementWhen mounting the antenna, it is necessary to consider thefollowing criteria:The mounting structure will need to be solid enough to withstandadditional loading on the antenna mount due to extreme wind, iceor snow (and in some cases large birds).For omni directional antennas, it is necessary to consider the effectof the mounting structure (tower mast or building) on the radiationpattern. Close in structures, particularly steel structures, can alterthe radiation pattern of the antenna. Where possible, omniantennas should always be mounted on the top of the mast or poleto minimise this effect. If this is not possible, mount the antenna ona horizontal outrigger to get it at least 1-2m away from thestructure. When mounting on buildings, a small mast or pole (2-4m)can significantly improve the radiation pattern by providingclearance from the building structure.For directional antennas, it is generally only necessary to considerthe structure in relation to the forward radiation pattern of theantenna, unless the structure is metallic, and of a solid nature. Inthis case it is also prudent to position the antenna as far away fromthe structure as is practical. With directional antennas, it is alsonecessary to ensure that the antenna cannot move in such a waythat the directional beamwidth will be affected. For long yagiantennas, it is often necessary to instal a fibreglass strut tostablilise the antenna under windy conditions.Alignment of Directional AntennasThis is generally performed by altering the alignment of theantenna whilst measuring the received signal strength. If the signalis weak, it may be necessary to pre-align the antenna using acompass, GPS, or visual or map guidance in order to “find” thewanted signal. Yagi antennas have a number of lower gain “lobes”centred around the primary lobe. When aligning for best signalstrength, it is important to scan the antenna through at least 90degrees, to ensure that the centre (strongest) lobe is identified.When aligning a directional antenna, avoid placing your hands orbody in the vicinity of the radiating element or the forward beampattern, as this will affect the performance of the antenna.Selecting AntennasThere are basically two types of antennas – omni directional, anddirectional.Omni directional 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 omniantennas such as the “co-linear” compress the sphere of energyinto the horizontal plane, providing a relatively flat “disc” shapedpattern which goes further because all of the energy is radiated inthe horizontal plane.Directional antennas are designed to concentrate the signal into“beam” of energy for transmission in a single direction (ie for point-to-point or remote 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 widthsof 30-50 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 (ie each pinconnects to the same numbered corresponding pin at the other endof the cable).The “V24” definition originally specified the DB25 connectorstandard, but this has been complicated by the emergence of theDB9 (pseudo) standard for asynch devices, and this connectorstandard has different pin assignments.The wiring standard is “unbalanced”, and provides for three basicdata transfer wires (TXD, RXD, and SG – signal ground).Hardware HandshakingHardware handshake lines are also employed to provide flowcontrol, however (in the telemetry industry) many devices do notalways support 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 differinghandshake implementations, it is sometimes necessary to “loop”handshake pins in order to fool the devices handshakingrequirements.In telemetry applications (particularly where port speeds can be setto the same rate as the radio systems over-air rate) then flowcontrol, and therefore handshaking, is usually NOT required. Itfollows that any devices that CAN be configured for “no flowcontrol” should be used in this mode to simplify cablingrequirements.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 forE Series modem when set for no handshaking).RF Feeders and ProtectionThe antenna is connected to the radio modem by way of an RFfeeder. In choosing the feeder type, one must compromisebetween the loss caused by the feeder, and the cost, flexibility, andbulk of lower loss feeders. To do this, it is often prudent to performpath analysis first, in order to determine how much “spare” signalcan be allowed to be lost in the feeder. The feeder is also a criticalpart of the lightning protection system.All elevated antennas may be exposed to induced or directlightning strikes, and correct grounding of the feeder and mast arean essential part of this process. Gas discharge lightning arrestersshould also be fitted to any site that stands elevated or alone,particularly in rural areas.

Ltd.Part D  System Planning and DesignPower Supply and EnvironmentalConsiderationsGeneralWhen mounting the equipment, consideration should be given tothe environmental aspects of the site. The cabinet should bepositioned so that it is shaded from hot afternoon sun, or icy coldwind. Whilst the radios are designed for harsh temperatureextremes, they will give a longer service life if operated in a morestable temperature environment. In an industrial environment, theradio modems should be isolated from excessive vibration, whichcan destroy electronic components, joints, and crystals.The cabinet should provide full protection from moisture, dust,corrosive atmospheres, and other aspects such as ants and smallvermin (who’s residues can be corrosive or conductive). The radiomodem will radiate heat from the in-built heatsink, and the higherthe transmitter duty cycle, the more heat will be radiated from theheatsink. Ensure there is sufficient ventilation in the form ofpassive or forced air circulation to ensure that the radio is able tomaintain quoted temperature limits.Power SupplyThe power supply should provide a clean, filtered DC source. Theradio modem is designed and calibrated to operate from a13.8VDC regulated supply, but will operate from 10-15 volts(filtered) DC.The power supply must be able to supply sufficient current toprovide clean filtered DC under the full current conditions of theradio modem (ie when transmitting full RF power). The currentrequirement is typically 120mA (230mA for EB450) in receivemode, and will vary in transmit mode according to RF output powerlevel (typically 0.5-1.5 amps, 1.3-2.5 amps for EB450).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 voltageunder full sun conditions.When calculating solar and battery capacity requirements, theconstant current consumption will be approximately equal to thetransmit current multiplied by the duty cycle of the transmitter, plusthe receive current multiplied by the (remaining) duty cycle of thereceiver.The Tx/Rx duty cycle will be entirely dependent on the amount ofdata being transmitted by the radio modem, unless the device hasbeen configured for continuous transmit, in which case theconstant current consumption will be equal to the transmit currentonly (at 100% duty cycle).Site EarthingThe radio must not be allowed to provide a ground path fromchassis to (DB9) signal ground or (-) battery ground. Ensure thatthe chassis mounting plate, power supply (-) earth, RTU terminaldevice, and lightning arrester (if fitted), are all securely earthed to acommon ground point to which an earth stake is attached. Pleasepay particular attention to 24VDC PLC systems using DC-DCconverters to supply 13.8Vdc.Caution: There is NO internal replaceable fuse, andtherefore the radio modem MUST be externally fused withthe fuse holder provided (ER450: 3 amp slo-blow fuse,EB450: 5 amp fast-blow fuse).

Eitherbase station may be taken out for maintenance without the need forany system down time. The automatic change-over is triggered by outof tolerance (alarm) conditions based on either RF and/or user datathroughput paramaters.Part E  Getting Started - EH450Features and Benefits• Individual and identical base stations with separate control logicchangeover panel• Modules are hot swapable without user downtime• Flexible antenna options – single, separate Tx & Rx, two Txand two Rx• Increased sensitivity with receiver pre-amplifier• Both on-line and off-line units monitored regardless of activestatus• External input for higher stability 10MHz reference – GPSderived• Also refer to the common Features and Benefits list of the ESeries Data RadioBase / Repeater UnitHot Standby Controller UnitBase / Repeater UnitEH450 Hot Standby Base / Repeater UnitNOTE: RF connectors not used or ETSI version Rear View
Page 32E Series Data Radio – User Manual© Copyright 2002 Trio DataCom Pty. Ltd.Operational DescriptionThe Hot Standby Controller (HSC) unit is a 1RU rack mountedmodule that interfaces to two physically separate base stations (each2RU rack mounted modules) via a number of RF and data cables.Both base stations are operating simultaneously and both units areconstantly receiving signals, however only data from one basestation, the “online” base station is directed to the user equipment. Theonline base station is the only base station transmitting at any time.The Hot Standby Controller has the following functions:• Diplex the transmit and receive paths (Assuming internalduplexer fitted), TX Only.• Amplify and split the incoming signal two ways so both basestations receive at once.• Monitor status reports from both base stations to identify faultsand swap over the online base station if required.• Switch the antenna via internal coaxial relay duplexer to theonline base station transmitter and inhibit the offline base stationfrom transmitting.• Switch the User A and B data ports through to the online basestation.An optocoupler based switch in the base station controller directs datato and from ports A and B on the rear panel directly to ports A and B onthe on-line base station without any involvement from the Hot Standbycontroller microcontrollers (apart from selecting the on-line base). Thisprovides protection of the system from failure of the microcontroller.As well as ports A and B, each base has a system port. The systemport of each base station is interfaced to the microcontroller on the HotStandby controller. This allows the microcontroller in charge ofselecting the base station to receive diagnostic messages from eachbase station to decide their health.The base station has it’s own system port on the rear panel and this isinterfaced to the Hot Standby Contruller Module. The HSC will routediagnostics at the rear panel system port to and from the system portsof the base stations.Mounting and EnvironmentalConsiderationsThe EH450 Hot Standby Base Station is housed as a 5RU 19” rackmounted set, encompassing 2 x 2RU Base Station units and 1 x 1RUHot Standby Controller unit. The mounting holes on the front panelsshould be used to secure the units to the rack.The unit should be mounted in a clean and dry location, protected fromwater, excessive dust, corrosive fumes, extremes of temperature anddirect sunlight. Please allow sufficient passive or active ventilation toallow the radio modem’s heatsink to operate efficiently.All permanent connections are made at the rear of the unit. Thisincludes: Power, Antenna, Communications Ports, Digital I/O andSystem Port. The front panel has an additional System Portconnection point for easy access.The Base Station front panel system ports must not be used while inthis config.Part E  Getting Started - EH450

Ltd.Communications PortsThe A & B Data Ports and System Ports of each Base Stationconnect directly to the Hot Standby Controller units correspondingports with the cables provided. Ensure all clamping screws on theData Port cables are firmly secured and the System Port cables areclipped in correctly. See figure below for further details.Note: Only the front or rear User System Port can be used at anyone time on the HSC.Power Supply and ProtectionThe EH450 has facilities for dual power supplies to provide for aredundant system. A separate power supply should be used for eachof the Base Station units. The Hot Standby Controller unit hasconnections for dual power supplies and it is recommended that thepower supplies from each of the Base Stations also be used to powerthe Hot Standby Controller unit. See Figure below for further details.See ER450 Quick Start Guide Section for detailed wiring information.The Hot Standby Controller units A & B Data Ports connect directly toyou application device and the System Port connects directly to yourlocal PC.

Both have the same functionality and canbe used for local diagnostics, firmware front panel downloads and hotstandby controller testing. To access the system port use thediagnostic/programming cable supplied.Note: Wnen connection is made to front panel system rear systemport is disabled.Alarm Status LEDsThere are 10 alarm LEDs on the fron panel, five for base 1 and five forbase 2. These LEDs provide a general indication of base stationstatus. More detailed base station status information is available byusing the diagnostic utility software.The indicated alarms for each base station are:Freq. => Frequency ErrorRxSig => Receive Signal (RF) ErrorData => Receive Data ErrorTxPower => Transmit Power (RF) ErrorSupply => DC Voltage ErrorThe status of each alarm is represented as follows:Green => No ErrorRed => Current (active) Error conditionAmber => Recovered Error conditionAny active or recovered error LEDs will turn to green after the resetalarms switch has been pushed or remotely reset.Part E  Getting Started - EH450
