Configuration, Network Management and Remote Diagnostics Software Page 9 E Series Data Radio User Manual Part C Applications Part C Applications Generic Connectivity Application Detail 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). SCADA Systems 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-tomultipoint (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. Page 10 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 shires or a greater city metropolis. Industry sectors include energy utilities (gas and electricity distribution), water and sewerage 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. © Copyright 2004 Trio DataCom Pty. Ltd. E Series Data Radio User Manual Part C Applications 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 applications 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) © Copyright 2004 Trio DataCom Pty. Ltd. Page 11 E Series Data Radio User Manual Part C Applications Digipeater Systems Backbone Store and Forward 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 applications master site. Information from the applications 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. 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 in half duplex mode (only key-up when transmitting data), so that each site is free to hear received signals from more than one source. Digipeater System Backbone Store and Forward System Page 12 © Copyright 2004 Trio DataCom Pty. Ltd. E Series Data Radio User Manual Part D System Planning and Design Part D 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 (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. © Copyright 2004 Trio DataCom Pty. Ltd.

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. 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. 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. Antenna Gain 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). 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 instal 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. Page 16 © Copyright 2004 Trio DataCom Pty. Ltd. E Series Data Radio User Manual Part D System Planning and Design Data Connectivity 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.

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). © Copyright 2004 Trio DataCom Pty. Ltd.

Page 19 E Series Data Radio User Manual Part D System Planning and Design 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. 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. Power Supply Site Earthing 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 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. 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 Caution: There is NO internal replaceable fuse, and therefore the radio modem MUST be externally fused with the fuse holder provided (ER450: 3 amp slo-blow fuse, EB450: 5 amp fast-blow fuse).

This guide provides stepby-step instructions, with simple explanations to get you up-andrunning. 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 modems heatsink to operate efficiently. Typical Radio Setup Page 24 © Copyright 2004 Trio DataCom Pty. Ltd. E Series Data Radio User Manual Part E Getting Started - ER450 ER450 Connections Layout 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 conjuction with the RJ-45 to DB9 Adaptor. TVIEW+ Adaptor Configuration: System Port Pin 1 Pin 2 Pin 3 Pin 4 Pin 5 Pin 6 Pin 7 Pin 8 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.

Communications Ports System Port RJ45 The System Port (available front and rear on EB/EH450) is a multifunction 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). © Copyright 2004 Trio DataCom Pty. Ltd. Page 25 E Series Data Radio User Manual Part E Getting Started - ER450 User Interfaces Ports A & B RS232 Connector Pin outs (DCE) Port A and B, Female DB9 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. 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 Page 26 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. © Copyright 2004 Trio DataCom Pty. Ltd. E Series Data Radio User Manual Part E Getting Started- ER450 Power Supply Requirements TVIEW+ Management Suite 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 requirments Radio Configuration Caution: There is NO internal replaceable fuse, and therefore the radio modem MUST be externally fused with the fuse holder provided (ER450: 3 amp slo-blow fuse, EB450: 5 amp fast-blow fuse, EH450 1 amp slo-blow fuse). 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 generic templates for the types of systems architecture you wish to employ. Example: Local configuration session Attach the programming cable from the PC to the System Port of the radio Launch TVIEW+ & Select Programmer Select Read the radio Change the configuration as required Select Write the parameters back to the radio Refer to Parts I & J TVIEW+ Management Suite for detailed operation of advanced features. The radio is designed to self protect, and will blow the external fuse if the voltage exceeds 16Vdc, or if reverse polarity is applied. 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. © Copyright 2004 Trio DataCom Pty. Ltd. Page 27 E Series Data Radio User Manual Part E Getting Started- ER450 Optimising the Antenna for best RX signal LED Indicators & Test Outputs LED Legend 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. 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. 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. Analog RSSI Output Characteristics - E Series Data Radio 4.5 RSSI (DC Volts) Port A Port B Pwr/TX Error Diagnosis OFF Synch/ RXSig OFF OFF ON OFF OFF ON OFF OFF ON External Supply Voltage out of spec. (1) RX VCO Out of Lock. (2) TX VCO Out of Lock. (3) ON ON 3.5 2.5 1.5 0.5 -120 -110 -100 -90 -80 -70 RF Level (dBm) -60 -50 -40 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. Page 28 © Copyright 2004 Trio DataCom Pty. Ltd. E Series Data Radio User Manual Part E Getting Started- ER450 Received Signal Indicator Verifying Operational Health The RX/SYNC LED is used to indicate the state of the receiver. 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). If the LED is off, no signal is being received. Note: Port A and Port Bs RxD and TxD will be Active on Data Flow LED Legend 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. Full Duplex PTP Master or Slave 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. Full Duplex PTMP Master Tx Half Duplex PTMP Slave Rx 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. Half Duplex Master or Slave (Tx) If data is alternately flowing in and out quickly, then the indicator appears orange. Half Duplex Master or Slave (Rx) © Copyright 2004 Trio DataCom Pty. Ltd.
