O Series Data Radio – User Manual Part C – Applications Part C – Applications Generic Connectivity Application Detail The O Series has been designed for SCADA and telemetry applications, and any other applications that use an ASCII communications protocol, and which connect physically using the RS-232 or RS-485 interface standard. 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 O Series radio modems. An ASCII protocol is any that consists of message strings formed from ASCII characters, that being defined as a 10 or 11 bit block including start and stop bits, 7 or 8 data bits and optional parity bit(s). Port set-up dialogue that includes the expressions “N,8,1”, or E,7,2” or similar indicate an ASCII protocol. Most of the dominant telemetry industry suppliers utilise proprietary ASCII protocols, and also common “open standard” industry protocols such as DNP3, MODBUS, TCP/IP, and PPP. These are all ASCII based protocols. Industries and Applications The O Series products are widely used in point-to-point and point-to-multipoint (multiple access) applications for remote interconnection of PLCs, RTUs, dataloggers, and other data monitoring and control devices - including specialist utility devices (such as powerline ACRs). In addition, other applications such as area wide security and alarm systems, public information systems (traffic flow and public signage systems) and environmental monitoring systems. Page 7 This is where one or more centralised control sites are used to monitor and control remote field devices over wide areas. Examples include regional utilities monitoring and controlling networks over entire councils or a greater city metropolis. Industry sectors include energy utilities (gas and electricity distribution), water and waste water utilities, catchment and environment groups (rivers, dams and catchment management authorities). Telemetry Systems Dedicated telemetry control systems interconnecting sequential devices either where cabling is not practical or distances are considerable. Examples include: • ore conveyor or slurry pipeline systems • simple water systems (pump and reservoir interlinking) • broadcast industry (linking studio to transmitter) etc. Information Systems Public Information systems such as freeway vehicle flow, travel time monitoring, feedback signage, parking signage systems and meteorological stations etc. © Copyright 2007 Trio DataCom Pty.

Ltd. O Series Data Radio – User Manual Part D – System Planning and Design Part E – System Planning and Design Obstructed Radio Path Understanding RF Path Requirements This path has an obstruction that will seriously degrade the signal arriving at the field site. A radio modem needs a minimum amount of received RF signal to operate reliably and provide adequate data throughput. In most cases, spectrum regulatory authorities will also define or limit the amount of signal that can be transmitted, and the transmitted power will decay with distance and other factors, as it moves away from the transmitting antenna. It follows, therefore, that for a given transmission level, there will be a finite distance at which a receiver can operate reliably with respect to the transmitter. Apart from signal loss due to distance, other factors that will decay a signal include obstructions (hills, buildings, foliage), horizon (effectively the bulge between two points on the earth), and factors such as fog, heavy rain-bursts, dust storms, etc. In order to ascertain the available RF coverage from a transmitting station, it will be necessary to consider these factors. This can be done in a number of ways, including (a) using basic formulas to calculate the theoretically available signal - allowing only for free space loss due to distance, (b) using sophisticated software to build earth terrain models and apply other correction factors such as earth curvature and the effects of obstructions, and (c) by actual field strength testing. It is good design practice to consider the results of at least two of these models to design a radio path. Examples of Predictive Path Modelling Clear line of site Radio path with good signal levels, attenuated only by free space loss. Page 10 © Copyright 2007 Trio DataCom Pty. Ltd. O Series Data Radio – User Manual Effect of Earth Curvature on Long Paths This path requires greater mast height to offset the earth curvature experienced at such a distance (73km). Part D – System Planning and Design Selecting Antennas Antennas 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 a “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 directional antenna is the yagi, which offers useable beam widths of 15-40 degrees. Even higher “gain” is available using parabolic “dish” type antennas such as gridpacks. 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). Page 11 © Copyright 2007 Trio DataCom Pty. Ltd. O Series Data Radio – User Manual Part D – System Planning and Design Antenna Placement RF Feeders and Protection When mounting the antenna, it is necessary to consider the following criteria: 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. 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, 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. 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. Common Cable Types Loss per 30.5m @ 915MHz Loss per 30.5m @ 2.4GHz RG213/U 7.4dB 23.6dB FSJ1-50 (¼” superflex) 5.6dB 9.9dB LDF4-50 (1/2” heliax) 2.2dB 2.3dB LDF5-50 (7/8” heliax) 1.2dB 3.7dB TX Power for Maximum EIRP (FCC) FCC Regulations allow up to 36 dBm effective isotropic radiated power (EIRP). To calculate the maximum transmitter power you need to know the gain of the antenna being used (see the FCC Approved Antenna List Appendix) and the cabling loss. The maximum transmitter power can then be calculated using the following formula: Maximum transmitter power (dBm) = 36dBm + cable loss (dB) – antenna gain (dBd) - 2.15. As an example, if we choose the BMY890K yagi from the FCC Approved Antenna List which has a gain of 10dBd and we know the cable loss is 3dB then the maximum output power is: Maximum output power (dBm) = 36 + 3 -10 - 2.15 = 26.85 dBm. Rounded down to 26dBm. Therefore the radio TX power should be set to 26dBm. Other countries may have different EIRP limits, but the same method for calculation applies. Page 12 © Copyright 2007 Trio DataCom Pty. Ltd. O Series Data Radio – User Manual Part D – System Planning and Design Power Supply and Environmental Considerations Power Supply The power supply should provide a clean, filtered DC source. The radio modem is designed and calibrated to operate from a 3.3VDC and 5VDC regulated supply. 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). 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.
