About the Radio | 15 Aprisa SR User Manual 3. About the Radio The 4RF Aprisa SR Radio The 4RF Aprisa SR is a point-to-multipoint digital radio providing secure narrowband wireless data connectivity for SCADA, infrastructure and telemetry applications. The radios carry a combination of serial data and Ethernet data between the base station, repeater stations and remote stations. A single Aprisa SR is configurable as a point-to-multipoint base station, a remote station or a repeater station.
16 | About the Radio Aprisa SR User Manual Product Overview Network Coverage and Capacity In a simple point-to-multipoint network, an Aprisa SR, configured as a base station, will communicate with multiple remote units in a given coverage area. With a link range of up to 60 km a typical deployment will have 30 – 50 remote stations attached to the base station. However, geographic features, such as hills, mountains, trees and foliage, or other path obstructions, such as buildings, tend to limit radio coverage. Additionally, geography may reduce network capacity at the edge of the network where errors may occur and require retransmission. However, the Aprisa SR uses Forward Error Correction (FEC) which greatly improves the sensitivity performance of the radio resulting in less retries and minimal reduction in capacity. Ultimately, the overall performance of any specific network will be defined by a range of factors including the geographic location, the number of remote stations in the base station coverage area and the traffic profile across the network. Effective network design will distribute the total number of remote stations across the available base stations to ensure optimal geographic coverage and network capacity. Remote Messaging On start-up, the remote station transmits a registration message to the base stations which responds with a registration response. This allows the base station to record the details of all the remote stations active in the network. If a remote station cannot register with the base station after multiple attempts (RF LED flashing red) within 10 minutes, it will automatically reboot. If a remote station has registered with the base station but then loses communication, it will automatically reboot within 6 minutes. There are two message types in the Aprisa SR network, broadcast messages and unicast messages. Broadcast messages are transmitted by the base station to the remote stations and unicast messages are transmitted by the remote station to the base station. All remotes within the coverage area will receive broadcast messages and pass them on to either the Ethernet or serial interface. The RTU determines if the message is intended for it and will accept it or discard it. Only the base station can receive the unicast messages transmitted from the remote station. Unicast messages are ignored by other remote stations which may be able to receive them.
About the Radio | 17 Aprisa SR User Manual Repeater Messaging The Aprisa SR uses a routed protocol throughout the network whereby messages contain source and destination addresses. Upon registration, the radios populate an internal neighbor table to identify the radios in the network. The remote stations will register with a base station, or a repeater, and the repeater registers with a base station. In networks with a repeater, the repeater must register with the base station before the remotes can register with the repeater. Additionally, all messages contain a ‘message type’ field in the header and messages are designated as either a ‘broadcast’ message, originating from a base station, or a ‘unicast’ message, originating from a remote station. In a network with a repeater, or multiple repeaters, the base station broadcasts a message which contains a message type, a source address and a destination address. The repeater receives the message and recognizes it is a broadcast message, from the message type and source address and re-broadcasts the message across the network. All remote stations in the coverage area will receive the message but only the radio with the destination address will act upon the message. Similarly, the remote station will send a unicast message which contains a message type (unicast) a source address and a destination address (the base station). The repeater will receive this message; recognize the message type and source address and forward it to the destination address. It is this methodology which prevents repeater-repeater loops. If there is repeater (A) which, in some circumstances, is able to pick up the RF signal from another repeater (B), it will not forward the message as it will only forward broadcast messages from the base station (recognized by the source address). For unicast messages the repeater (A) will recognize that the message (from repeater (B)) is not from a remote with which it has an association and similarly ignore the message.

About the Radio | 19 Aprisa SR User Manual Architecture Product Operation There are three components to the wireless interface: the Physical Layer (PHY), the Data Link Layer (DLL) and the Network Layer. These three layers are required to transport data across the wireless channel in the Point-to-Multipoint (PMP) configuration. The Aprisa SR DLL is largely based on the 802.15.4 MAC layer using a proprietary implementation. Physical Layer The Aprisa SR PHY uses a one or two frequency ½ duplex transmission mode which eliminates the need for a duplexer. However, a Dual Antenna port option is available for separate transmit and receive antenna connection to support external duplexers or filters (half duplex operation). Remote nodes are predominantly in receive mode with only sporadic bursts of transmit data. This reduces power consumption. The Aprisa SR is a packet based radio. Data is sent over the wireless channel in discrete packets / frames, separated in time. The PHY demodulates data within these packets with coherent detection. The Aprisa SR PHY provides carrier, symbol and frame synchronisation predominantly through the use of preambles. This preamble prefixes all packets sent over the wireless channel which enables fast synchronisation. Data Link Layer / MAC layer The Aprisa SR PHY enables multiple users to be able to share a single wireless channel; however a DLL is required to manage data transport. The two key components to the DLL are channel access and hop by hop transmission. Channel Access The Aprisa SR radio has two modes of channel access, Access Request and Listen Before Send. Access Mode Function Access Request Channel access scheme where the base stations controls the communication on the channel. Remotes ask for access to the channel, and the base station grants access if the channel is not occupied. Listen Before Send Channel access scheme where network elements listen to ensure the channel is clear, before trying to access the channel.
20 | About the Radio Aprisa SR User Manual Access Request This scheme is particularly suited to digital SCADA systems where all data flows through the base station. In this case it is important that the base station has contention-free access as it is involved in every transaction. The channel access scheme assigns the base station as the channel access arbitrator and therefore inherently it has contention-free access to the channel. This means that there is no possibility of contention on data originating from the base station. As all data flows to or from the base station, this significantly improves the robustness of the system. All data messages are controlled via the AG (access grant) control message and therefore there is no possibility of contention on the actual end user data. If a remote station accesses the channel, the only contention risk is on the AR (access request) control message. These control messages are designed to be as short as possible and therefore the risk of collision of these control messages is significantly reduced. Should collisions occur these are resolved using a random back off and retry mechanism. As the base station controls all data transactions multiple applications can be effectively handled, including a mixture of polling and report by exception. Listen Before Send The Listen Before Send channel access scheme is realized using Carrier Sense Multiple Access (CSMA). In this mode, a pending transmission requires the channel to be clear. This is determined by monitoring the channel for other signals for a set time prior to transmission. This results in reduced collisions and improved channel capacity. There are still possibilities for collisions with this technique e.g. if two radios simultaneously determine the channel is clear and transmit at the same time. In this case an acknowledged transaction may be used. The transmitter requests an ACK to ensure that the transmission has been successful. If the transmitter does not receive an ACK, then random backoffs are used to reschedule the next transmission. Hop by Hop Transmission Hop by Hop Transmission is realized in the Aprisa SR by adding a MAC address header to the packet. For 802.15.4, there are 2 addresses, the source and destination addresses.
About the Radio | 21 Aprisa SR User Manual Network Layer Packet Routing Packet routing is realized in the Aprisa SR by adding a network address header to the packet. This contains source and destination addresses. For the Network Layer, there are 2 addresses, the address of the originating radio and the address of the terminating radio (i.e. end to end network). This is required for routing packets across multiple hops e.g. PMP with repeaters. The Aprisa SR uses an automated method for performing address assignment and routing information. There are two types of packets: unicast and broadcast. Only the base station sends broadcasts which are received by all remote stations. User packets are not interpreted as the radio link is transparent. Traffic Data originating on the base station is broadcast to all repeater stations and remote stations Data originating on a remote station is unicast to the base station only This can be via multiple repeater stations. Data originating on a repeater station is unicast to the base station only Data originating on a base station serial port is terminated on remote station serial ports only Data originating on a base station Ethernet port is terminated on remote station Ethernet ports or serial ports (Terminal Server mode) User Traffic User traffic is prioritized depending on the Serial and Ethernet Data Priority options (see ‘Serial > Advanced’ on page 99 and ‘Ethernet > Advanced’ on page 106). If the Serial and Ethernet Data Priority options are equal, then first come first served is invoked. Repeater stations repeat traffic also on a first come first served basis. Management Traffic Ethernet Management Traffic is also prioritized relative to user traffic (see ‘Ethernet > Advanced’ on page 106).

26 | About the Radio Aprisa SR User Manual Network Software Upgrade During a network software upgrade, the AUX LED flashes orange on the base station and all remote stations. Test Mode Remote station and repeater station radios have a Test Mode which presents a real time visual display of the RSSI on the LED Display panel. This can be used to adjust the antenna for optimum signal strength (see ‘Maintenance > Test Mode’ on page 128 for Test Mode options). To enter Test Mode, press and hold the ENTER button on the radio LED panel until all the LEDs flash green (about 3 - 5 seconds). The response time is variable and can be up to 5 seconds. To exit Test Mode, press and hold the ENTER button until all the LEDs flash red (about 3 – 5 seconds). The RF LED will be green if the network is operating correctly. Note: Test Mode traffic has a low priority but could affect customer traffic depending on the relative priorities setup. The RSSI result is displayed on the LED Display panel as a combination of LED states:
Product Options | 27 Aprisa SR User Manual 4. Product Options Dual Antenna Port The standard Aprisa SR uses a one or two frequency ½ duplex transmission mode which eliminates the need for a duplexer. However, a dual antenna port option is available for separate transmit and receive antenna connection to support external duplexers or filters. The transmission remains half duplex. Example Part: Part Number Part Description APSR-N400-012-DO-12-ETAA 4RF SR, BR, 400-470 MHz, 12.5 kHz, DO, 12 VDC, ET, AA
28 | Product Options Aprisa SR User Manual Protected Station The Aprisa SR Protected Station provides radio and user interface protection for Aprisa SR radios. The RF ports and interface ports from two standard Aprisa SR Radios are switched to the standby radio if there is a failure in the active radio. Example Part: Part Number Part Description APSR-R400-012-SO-12-ETAA 4RF SR, PS, 400-470 MHz, 12.5 kHz, SO, 12 VDC, ET, AA The Aprisa SR Protected Station is comprised of an Aprisa SR Protection Switch and two standard Aprisa SR radios. This configuration provides the ability to ‘hot-swap’ a failed radio without interrupting user traffic on the active radio. Additionally, retains the full temperature range specification of a single radio. The Aprisa SR radios can be any of the currently available Aprisa SR radio frequency bands, channel sizes or single / dual antenna port options. By default, the Aprisa SR Protected Station is configured with the left hand radio (A) designated as the primary radio and the right hand radio (B) designated as the secondary radio. Each radio is configured with its own unique IP and MAC address and the address of the partner radio. On power-up, the primary radio will assume the active role and the secondary radio will assume the standby role. If, for some reason, only one radio is powered on it will automatically assume the active role. Operation In normal operation, the active radio carries all RS-232 serial and Ethernet traffic over the radio link and the standby radio is unused with its transmitter turned off. Both radios are continually monitored for correct operation and alarms are raised if an event occurs. Both the active and standby radios send regular ‘keep alive’ messages to each other to indicate if they are operating correctly. In the event of a failure on the active radio, the RF link and user interface traffic is automatically switched to the standby radio. The failed radio can then be replaced in the field without interrupting user traffic (see ‘Replacing a Protected Station Faulty Radio’ on page 33).
Product Options | 29 Aprisa SR User Manual Configuration Management The Primary and Secondary radios are managed with the embedded web-based management tool, SuperVisor (see ‘Managing the Radio’ on page 59) by using either the Primary or Secondary IP address. Configuration changes in one of the radios will automatically be reflected in the partner radio. To ensure all remote stations are registered to the correct (active) base station, changes to the Network Table are automatically synchronized from the active radio to the standby radio. The Network Table is only visible on the active radio. This synchronization does not occur if the Hardware Manual Lock is active. Switch Over The switch over to the standby radio can be initiated automatically, on fault detection, or manually via the Hardware Manual Lock switch on the Protection Switch or the Software Manual Lock from SuperVisor. Additionally, it is possible to switch over the radios remotely without visiting the station site, via the remote control connector on the front of the Protection Switch. On detection of an alarm fault the switch over time is less than 0.5 seconds. Some alarms may take up to 5 seconds to be detected. The Protection Switch has a switch guard mechanism to prevent protection switch oscillation. If a switch-over has occurred, subsequent switch-over triggers will be blocked if the guard time has not elapsed. The guard time starts at 20 seconds and doubles each switch-over to a maximum of 320 seconds and halves after a period of two times the last guard time with no protection switch-overs. Switching Criteria The Protected Station will switch over operation from the active to the standby radio if any of the configurable alarm events occur, or if there is a loss of the ‘keep alive’ signal from the active radio. It is possible to configure the alarm events which will trigger the switch over. It is also possible to prevent an alarm event triggering a switch over through the configuration of blocking criteria. Any of the following alarm events can be set to trigger or prevent switching from the active radio to the standby radio (see ‘Events > Events Setup’ on page 137). PA current Tx AGC Tx reverse power Thermal shutdown Temperature threshold Thermal shutdown RSSI Threshold RX Synthesizer Not Locked Rx CRC errors RF no receive data Ethernet port 1 – no receive data Ethernet port 2 – no receive data Ethernet port 1 - data receive errors Ethernet port 2 – data receive errors Ethernet port 1 – data transmit errors Ethernet port 2 - data transmit errors Serial port – no receive data Serial port – data receive errors Component failure Calibration failure Configuration not supported Protection Hardware Failure It will not attempt to switch over to a standby radio which has power failure. It will also not switch over to a standby radio with an active alarm event which has been configured as a ‘blocking criteria’.
30 | Product Options Aprisa SR User Manual Switch over will be initiated once either of these conditions is rectified, i.e. power is restored or the alarm is cleared. Hardware Manual Lock The Hardware Manual Lock switch on the Protection Switch provides a manual override of the active / standby radio. When this lock is activated, the selected radio (A or B) becomes the active radio regardless of the Software Manual Lock and the current switching or block criteria. When the lock is deactivated (set to the Auto position), the protection will become automatic and switching will be governed by normal switching and blocking criteria. The state of the switch is indicated by the three LEDs on the Protection Switch: A LED B LED Locked LED State Green Off Off Auto - Radio A is active Off Green Off Auto - Radio B is active Green Off Orange Manual Lock to radio A Off Green Orange Manual Lock to radio B The Protection Switch also has a Software Manual Lock (see ‘Protected Station: Maintenance > Protection’ on page 179). The Hardware Manual Lock takes precedence over Software Manual Lock if both diagnostic functions are activated i.e. if the Software Manual Lock is set to ‘Primary’ and the Hardware Manual Lock set to ‘Secondary’, the system will set the Secondary radio to Active. When a Hardware Manual Lock is deactivated (set to the Auto position), the Software Manual Lock is re-evaluated and locks set appropriately. Remote Control The switch over to the standby radio can be initiated via the Remote Control connector on the front of the Protection Switch. This control will only operate if the Hardware Manual Lock switch is set to the Auto position. The inputs are logic inputs with 4700 Ω pullup to +3.3 VDC. They require a pull down to ground to activate the control. The ground potential is available on the connector (see ‘Protection Switch Remote Control Connections’ on page 215).

40 | Product Options Aprisa SR User Manual USB RS-232 Serial Port The Aprisa SR USB host port is predominantly used for software upgrade and diagnostic reporting. However, it can also be used to provide an additional RS-232 DCE serial port for customer traffic. This is accomplished with a USB to RS-232 serial converter cable. This plugs into the USB host port connector and can be terminated with the required customer connector. This additional RS-232 serial port is enabled with the SuperVisor mode setting in Serial Port Settings (see ‘Serial > Port Setup’ on page 95). USB RS-232 operation The USB serial converter buffers the received data frames into 64 byte blocks separated by a small inter-frame gap. For the majority of applications, this fragmentation of egress frames is not an issue. However, there are some applications that may be sensitive to the inter-frame gap, therefore, these applications need consideration. A 5 ms inter-frame is recommended for the applications that are sensitive to inter-frame gap timings. On a USB RS-232 port, Modbus RTU can operate up to 9600 baud with all packet sizes and up to 115200 if the packet size is less than 64 bytes. The standard RS-232 port is fully compatible with Modbus RTU at all baud rates.

Preparation | 45 Aprisa SR User Manual 6. Preparation Bench Setup Before installing the links in the field, it is recommended that you bench-test the links. A suggested setup for basic bench testing is shown below: When setting up the equipment for bench testing, note the following: Earthing Each radio should be earthed at all times. The radio earth point should be connected to a protection earth. Attenuators In a bench setup, there should be 60 - 80 dB at up to 1 GHz of 50 ohm coaxial attenuation, capable of handling the transmit power of +37 dBm (5 W) between the radios’ antenna connectors. Splitter If more than two radios are required in your bench setup, a multi-way splitter is required. The diagram shows a two way splitter. This splitter should be 50 ohm coaxial up to 1 GHz and capable of handling the transmit power of +37 dBm (5 W). Cables Use double-screened coaxial cable that is suitable for use up to 1 GHz at ≈ 1 metre. CAUTION: Do not apply signals greater than +10 dBm to the antenna connection as they can damage the receiver.
46 | Preparation Aprisa SR User Manual Path Planning The following factors should be considered to achieve optimum path planning: Antenna Selection and Siting Coaxial Cable Selection Linking System Plan Antenna Selection and Siting Selecting and siting antennas are important considerations in your system design. The antenna choice for the site is determined primarily by the frequency of operation and the gain required to establish reliable links. Base or Repeater Station The predominant antenna for a base station or a repeater station is an omni-directional collinear gain antenna. Omni Directional Collinear Antennas Factor Explanation Frequency Often used in 380-530 MHz bands Gain Varies with size (5 dBi to 8 dBi typical) Wind loading Minimal Tower aperture required Minimal Size Range from 2 m to 3 m length Polarization Vertical
Preparation | 47 Aprisa SR User Manual Remote station There are two main types of directional antenna that are commonly used for remote stations, Yagi and corner reflector antennas. Yagi Antennas Factor Explanation Frequency Often used in 350-600 MHz bands Gain Varies with size (typically 11 dBi to 16 dBi) Stackable gain increase 2 Yagi antennas (+ 2.8 dB) 4 Yagi antennas (+ 5.6 dB) Size Range from 0.6 m to 3 m in length Front to back ratio Low (typically 18 to 20 dB) It is possible to increase the gain of a Yagi antenna installation by placing two or more of them in a stack. The relative position of the antennas is critical. Example of stacked antennas
48 | Preparation Aprisa SR User Manual Corner Reflector Antennas Factor Explanation Frequency Often used in 330-960 MHz bands Gain Typically 12 dBi Size Range from 0.36 m to 0.75 m in length Front to back ratio High (typically 30 dB) Beamwidth Broad (up to 60°) Antenna Siting When siting antennas, consider the following points: A site with a clear line of sight to the remote radio is recommended. Pay particular attention to trees, buildings, and other obstructions close to the antenna site. Example of a clear line-of-sight path Any large flat areas that reflect RF energy along the link path, for instance, water, could cause multipath fading. If the link path crosses a feature that is likely to cause RF reflections, shield the antenna from the reflected signals by positioning it on the far side of the roof of the equipment shelter or other structure. Example of a mid-path reflection path The antenna site should be as far as possible from other potential sources of RF interference such as electrical equipment, power lines and roads. The antenna site should be as close as possible to the equipment shelter. Wide angle and zoom photographs taken at the proposed antenna location (looking down the proposed path), can be useful when considering the best mounting positions.
Preparation | 49 Aprisa SR User Manual Coaxial Feeder Cables To ensure maximum performance, it is recommended that you use good quality low-loss coaxial cable for all feeder runs. When selecting a coaxial cable consider the following: Factor Effect Attenuation Short cables and larger diameter cables have less attenuation Cost Smaller diameter cables are cheaper Ease of installation Easier with smaller diameter cables or short cables For installations requiring long feeder cable runs, use the LCF78, LCF12 or CNT-400 feeder cable or equivalent: Part Number Part Description Specification RFS LCF78 50JA Feeder Cable, 7/8’, CELLFLEX, Low Loss, Std, /m, MOQ 50 Low loss 7/8’ (22.2 mm) feeder cable Bending radius of 125 mm min Attenuation of 2.5 dB / 100m @ 450 MHz RFS LCF12 50J Feeder Cable, 1/2’, CELLFLEX, Low Loss, Std, /m, MOQ 50 Low loss 0.5’ (12.7 mm) feeder cable Bending radius of 125 mm min Attenuation of 4.7 dB / 100m @ 450 MHz RFI CNT 400 Feeder, CNT-400, 10.8mm, Double Shielded Solid Polyethylene Low loss 0.4’ (10.8 mm) feeder cable UV protected black Polyethylene, bonded AL tape outer conductor Bending radius of 30 mm min Attenuation of 8.8 dB / 100m @ 450 MHz For installations requiring short feeder cable runs, use the RFI 8223 feeder cable or equivalent: Part Number Part Description Specification RFI 8223 Feeder, RG 223 5.4mm d, Double Shielded Solid Polyethylene Bending radius of 20 mm min Attenuation of 30.5 dB / 100m @ 450 MHz When running cables: Run coaxial feeder cable from the installation to the antenna, ensuring you leave enough extra cable at each end to allow drip loops to be formed. Terminate and ground the feeder cables in accordance with the manufacturers’ instructions. Bond the outer conductor of the coaxial feeder cables to the base of the tower mast. Linking System Plan All of the above factors combine in any proposed installation to create a Linking System Plan. The Linking System Plan predicts how well the radios will perform after it is installed. Use the outputs of the Linking System Plan during commissioning to confirm the radios have been installed correctly and that it will provide reliable service.
50 | Preparation Aprisa SR User Manual Site Requirements Power Supply Ensure a suitable power supply is available for powering the radio. The nominal input voltage for a radio is +13.8 VDC (negative earth) with an input voltage range of +10 to +30 VDC. The maximum power input is 30 W. WARNING: Before connecting power to the radio, ensure that the radio is grounded via the negative terminal of the DC power connection. Equipment Cooling If the Aprisa SR is operated in an environment where the ambient temperature exceeds 50°C, the Aprisa SR convection air flow over the heat sinks must be considered.

Managing the Radio | 59 Aprisa SR User Manual 8. Managing the Radio SuperVisor The Aprisa SR contains an embedded web server application (SuperVisor) to enable element management with any major web browser (such as Mozilla Firefox or Microsoft® Internet Explorer). SuperVisor enables operators to configure and manage the Aprisa SR base station radio and repeater / remote station radios over the radio link. The key features of SuperVisor are: Full element management, configuration and diagnostics Manage the entire FAN (Field Area Network) from the Base Station (remote management of elements) Managed network software distribution and upgrades Performance and alarm monitoring of the entire network, including RSSI, alarm states, time-stamped events, etc. View and set standard radio configuration parameters including frequencies, transmit power, channel access, serial, Ethernet port settings Set and view security parameters User management Connecting to SuperVisor The predominant management connection to the Aprisa SR radio is with an Ethernet interface using standard IP networking. There should be only one Ethernet connection from any radio in the FAN to the management network. The Aprisa SR has a factory default IP address of 169.254.50.10 with a subnet mask of 255.255.0.0. This is an IPv4 Link Local (RFC3927) address which simplifies the connection to a PC. Each radio in the FAN must be set up with a unique IP address on the same subnet. The Aprisa SR Protected Station radio A (left radio) has a factory default IP address of 169.254.50.10 and radio B (right radio) has a factory default IP address of 169.254.50.20, both with a subnet mask of 255.255.0.0. To change the Aprisa SR IP address: 1. Set up your PC for a compatible IP address e.g. 169.254.50.1 with a subnet mask of 255.255.0.0. 2. Connect your PC network port to one of the Aprisa SR Ethernet ports. 3. Open a browser and enter http://169.254.50.10. 4. Login to the radio with the default Username ‘admin’ and Password ‘admin’. 5. Change the IP address to conform to the network plan in use.
60 | Managing the Radio Aprisa SR User Manual Management PC Connection The active management PC must only have one connection to the FAN as shown by path . There should not be any alternate path that the active management PC can use via an alternate router or alternate LAN that would allow the management traffic to be looped as shown by path . When logging into a FAN, it is important to understand the relationship between the Local Radio and the Remote Radios. The Local Radio is the radio that your IP network is physically connected to. If the Local Radio is a base station, SuperVisor manages the base station and all the repeater stations and remote stations in the FAN. If the Local Radio is a remote station or repeater station, SuperVisor only manages the remote / repeater station radio logged into.

Managing the Radio | 91 Aprisa SR User Manual Packet Size (Bytes) This parameter sets the maximum over-the-air packet size in bytes. A smaller maximum Packet Size is beneficial when many remote stations or repeater stations are trying to access the channel. The default setting is 1550 bytes. As radios dispatched from the factory have a Packet Size set to the maximum value of 1550 bytes, if a new radio is installed in an existing Field Access Network (FAN), the Packet Size must be changed to ensure it is the same value for all radios in the FAN. The new radio will not register an existing FAN if the Packet Size is not the same as the other radios in the FAN. This packet size includes the wireless protocol header and security payload (0 to 16 bytes). The length of the security header depends on the level of security selected. When the security setting is 0, the maximum user data transfer over-the-air is 1516 bytes. When encryption is enabled, the entire packet of user data (payload) is encrypted. If authentication is being used, the security frame will be added (up to 16 bytes). The wireless protocol header is then added which is proprietary to the Aprisa SR. This is not encrypted. Packet Time to Live (ms) This Time To Live (TTL) parameter sets the time a packet is allowed to live in the system before being dropped if it cannot be transmitted over the air. It is used to prevent old, redundant packets being transmitted through the Aprisa SR network. The default setting is 1500 ms. In the case of serial poll SCADA networks such as MODBUS and IEC 60870.50.101, it is important to ensure the replies from the RTU are in the correct sequence and are not timed out replies from Master requests. If the TTL value is too long, the SCADA master will detect sequence errors. It is recommended to use a TTL which is half the serial SCADA timeout. This is commonly called the ‘scan timeout’ or ‘link layer time out’ or ‘retry timeout’. When using TCP protocols, a TTL of 1500 ms is recommended because a TCP re-transmission usually occurs after approximately 3 second. In SCADA networks which use both serial and Ethernet, it is recommended that the TTL is set to half the serial SCADA timeout for serial remotes, and 1500 ms for Ethernet (TCP) remotes. For example, if the serial SCADA timeout is 1000 ms, a remote radio which is connected to the serial RTU should be set to 500 ms, a remote radio which is connected to a Ethernet (TCP) RTU should have a 1500 ms timeout. In this case, the base station TTL should be set to 1500 ms as well; or which ever is the longer TTL of serial or Ethernet.
92 | Managing the Radio Aprisa SR User Manual Packet Filtering Each Aprisa SR radio can filter packets not destined for itself. The Packet Filtering parameter controls this functionality. In an Aprisa SR network, all communication from remote stations is destined for the base station in the Aprisa SR network communication protocol. In a repeater network, a remote station will send a message to the base station. The repeater station will receive this and then repeat the message. The repeated message will then be received by the base station. Other remote stations connected to the repeater station will receive this message and depending on the Packet Filtering parameter, either forward this packet or discard it. This filtering capability can provide the ability for remote stations to communicate with each other when connected to a repeater, particularly useful in the event of losing communication with a SCADA Master, assuming the Aprisa SR network is still operational. Note: IP Header Compression must be disabled for this feature to operate correctly (see ‘IP Header Compression Ratio’ on page 93). Access Mode Function Disabled Every packet received by the radio will be forwarded to the relevant interface. Automatic The radio will filter (discard) packets not destined for itself according to the Aprisa SR traffic protocols The default setting is Automatic. Note: The Aprisa SR network is transparent to the protocol being transmitted; therefore the Packet Filtering parameter is based on the Aprisa SR addressing and network protocols, not the user (SCADA, etc.) traffic protocols.
Managing the Radio | 93 Aprisa SR User Manual LISTEN BEFORE SEND When the Access Mode is set for Listen Before Send, the Listen Before Send parameters can be set: ACK This parameter determines if unicast requests from the remote station are acknowledged by the base station. Receiving acknowledgments increases reliability of transport but reduces available channel capacity so if application has the capability to handle lost or duplicate messages, the ACK should be disabled. When enabled, the transmitter requests an ACK to ensure that the transmission has been successful. If the transmitter does not receive an ACK, then random back-offs are used to reschedule the next transmission. The default setting is enabled. DATA COMPRESSION IP Header Compression Ratio The IP Header Compression implements TCP/IP ROHC v2 (Robust Header Compression v2. RFC4995, RFC5225, RFC4996) to compress the IP header. IP Header compression module comprises of two main components, Compressor and Decompressor. Both these components maintain some state information for an IP flow to achieve header compression. However, for reasons like packet drops or station reboots this state information can go out of sync between compressor and decompressor resulting in compression and/or decompression failure resulting in loss of packets. The Compression Ratio controls the rate at which compressor and decompressor synchronize state information with each other. Frequent synchronization results in reduced ratio. IP Header Compression Ratio Function Compression Disabled Disables IP Header Compression. High State information is synchronized less frequently thus achieving the best compression ratio. Medium State information is synchronization less frequently than ‘High’ setting but more frequently than ‘Low’ setting. Low State information is synchronized frequently thus reducing the compression ratio. The default setting is High.

If the Aprisa SR buffer is full, the CTS goes OFF. In the case of radio link failure the signal goes to OFF (-ve) state. Inter-Frame Gap (chars) This parameter defines the gap between successive serial data frames. It is used to delimit the serial data to define the end of a packet. The Inter-Frame Gap limits are 0.5 to 16 chars. The default setting is 3.5 chars.
Managing the Radio | 97 Aprisa SR User Manual TERMINAL SERVER SETTINGS This menu item is only applicable if the serial port has an operating mode of Terminal Server. The Terminal Server operating mode provides encapsulation of serial data into an IP packet (TCP or UDP). A server connected to a base station Ethernet port can communicate with all remote station Ethernet ports and serial ports. Note: The current Aprisa SR has one serial port so there will be only one record. Local Address This parameter displays the IP address of this radio. Port This parameter sets the port number of the local serial port. The valid port number range is greater than or equal to 1024 and less than or equal to 49151 but with exclusions of 0, 5445, 6445, 9930 or 9931. The default setting is 20000. Remote Address This parameter sets the IP address of the server connected to the base station Ethernet port. Port This parameter sets the port number of the server connected to the base station Ethernet port. The default setting is 0. Protocol This parameter sets the IP protocol used for terminal server operation. The default setting is TCP.
98 | Managing the Radio Aprisa SR User Manual Mode This parameter defines the mode of operation of the terminal server connection. The default setting is Client and Server. Mode Function Client The radio will attempt to establish a TCP connection with the specified remote unit. Server The radio will listen for a TCP connection on the specified local port. Data received from any client shall be forwarded to the associated serial port while data received from that serial port shall be forwarded to every client with an open TCP connection. If no existing TCP connections exist, all data received from the associated serial port shall be discarded. Client and Server The radio will listen for a TCP connection on the specified local port and if necessary, establish a TCP connection with the specified remote unit. Data received from any client shall be forwarded to the associated serial port while data received from that serial port shall be forwarded to every client with an open TCP connection. Inactivity Timeout (seconds) This specifies the duration (in seconds) to automatically terminate the connection with the remote TCP server if no data has been received from either the remote TCP server or its associated serial port for the duration of the configured inactivity time. TCP Keep Alive A TCP keepalive is a message sent by one device to another to check that the link between the two is operating, or to prevent the link from being broken. If the TCP Keep Alive is enabled, the radio will be notified if the TCP connection fails. If the TCP Keep Alive is disabled, the radio relies on the Inactivity Timeout to detect a TCP connection failure. The default setting is disabled. Note: An active TCP Keep Alive will generate a small amount of extra network traffic.
Managing the Radio | 99 Aprisa SR User Manual Serial > Advanced This page provides the setup for the serial port advanced settings. SERIAL PORT ADVANCED Serial Data Priority The Serial Data Priority controls the priority of the serial customer traffic relative to the Ethernet customer traffic. If equal priority is required to Ethernet traffic, this setting must be the same as the Ethernet Data Priority setting (see ‘Ethernet Data Priority’ on page 107). The serial data priority can be set to Very High, High, Medium and Low. The default setting is Very High. A queuing system is used to prioritize traffic from the serial and Ethernet interfaces for over the air transmission. A weighting may be given to each data type and this is used to schedule the next transmission over the air e.g. if there are pending data packets in multiple buffers but serial data has a higher weighting it will be transmitted first. The serial buffer is 20 serial packets (1 packet can be up to 512 bytes). There are four priority queues in the Aprisa SR: Very High, High, Medium and Low. Data is added to one of these queues depending on the priority setting. Data leaves the queues from highest priority to lowest: the Very High queue is emptied first, followed by High then Medium and finally Low.

Managing the Radio | 115 Aprisa SR User Manual Security > SNMP In addition to web-based management (SuperVisor), the FAN can also be managed using the Simple Network Management Protocol (SNMP). MIB files are supplied, and these can be used by a dedicated SNMP Manager, such as Castle Rock’s SNMPc, to access most of the radio’s configurable parameters. For communication between the SNMP manager and the radio, Access Controls and Community strings must be set up as described in the following sections. A SNMP Community String is used to protect against unauthorized access (similar to a password). The SNMP agent (radio or SNMP manager) will check the community string before performing the task requested in the SNMP message. ACCESS CONTROL SETUP A SNMP Access Control is the IP address of the radio used by an SNMP manager or any other SNMP device to access the radio. The Aprisa SR allows access to the radio from any IP address. Read Only The default Read Only community string is public. Read Write The default ReadWrite community string is private.
116 | Managing the Radio Aprisa SR User Manual SNMP Manager Setup The SNMP manager community strings must be setup to access the base station and remote / repeater stations. To access the base station, a community string must be setup on the SNMP manager the same as the community string setup on the radio (see ‘Security > SNMP’ on page 115). SNMP access to remote / repeater stations can be achieved by using the radio’s IP address and the normal community string or by proxy in the base station. SNMP Access via Base Station Proxy To access the remote / repeater stations via the base station proxy, the community strings must be setup on the SNMP manager in the format: ccccccccc:bbbbbb Where: ccccccccc is the community string of the base station and bbbbbb is the last 3 bytes of the remote station MAC address (see ‘Network Status > Network Table’ on page 158) for the remote station MAC address. The SNMP Proxy Support must be enabled for this method of SNMP access to operate (see ‘SNMP Proxy Support’ on page 112).

Managing the Radio | 131 Aprisa SR User Manual Maintenance > Licence LICENCE Fully Featured Radio When a fully featured Aprisa SR radio is purchased (indicated by the AA), it contains the licences which activate Remote Management, Ethernet Traffic, and SNMP Management e.g. Part Number Part Description APSR-N400-012-SO-12-ETAA 4RF Aprisa SR, BR, 400-470 MHz, 12.5 kHz, SO, 12 VDC, ET, AA Serial Only Radio If a Serial Only Aprisa SR radio is purchased (indicated by the A1), Ethernet Traffic is not enabled. Part Number Part Description APSR-N400-012-SO-12-ETA1 4RF Aprisa SR, BR, 400-470 MHz, 12.5 kHz, SO, 12 VDC, ET, A1 Feature Licences Feature Licences can be purchased to enable features if they were not purchased initially. One license key is required per feature and per radio serial number. Part Number Part Description APSA-LSRF-FET 4RF Aprisa SR Acc, Licence, Feature, Ethernet Traffic When Ethernet traffic is enabled, the Ethernet port status must be set to enabled to allow Ethernet data communication over the radio link (see ‘Ethernet > Port Setup’ on page 101). In this software version, Remote Management and SNMP management are enabled by default.
132 | Managing the Radio Aprisa SR User Manual Maintenance > Advanced NETWORK Node Registration Retry (sec) This parameter sets the base station poll time at startup or the remote / repeater station time between retries until registered. The default setting is 10 seconds. Base Station Announcement Period (min) This parameter sets the period between base station polls post startup. The default setting is 1440 minutes (24 hours). When a new base station powers on, it announces its presence and each remote that receives the announcement message will be advised that a new base station is present and that they should re-register. This allows the new base station to populate its Network Table, with knowledge of the nodes in the network. If, during this initial period, there is some temporary path disturbance to one or more remotes, they may miss the initial announcement messages and be left unaware of the base station change. For this reason, the base station must periodically send out announcement messages to pick up any stray nodes and the period of these messages is the base station Announcement Period. Setting this parameter to 0 will stop further announcement messages being transmitted. Node Missed Poll Count This parameter sets the number of times the base station attempts to poll the FAN at startup or if a duplicate IP is detected when a remote / repeater station is replaced. The default setting is 3.
Managing the Radio | 133 Aprisa SR User Manual Discover Nodes This parameter when activated triggers the base station to poll the FAN with Node Missed Poll Count and Node Registration Retry values. Decommission Node This parameter when activated resets the FAN registrations to remove the entire FAN from service. Note: Take care using this option. Broadcast Time This parameter when activated sends the base station Date / Time setting to all the Remote and repeater stations in the FAN and sets their Date / Time. This option applies to the base station only. Automatic Route Rediscovery This parameter enables the radio to transmit route discovery messages when packets are unacknowledged. When enabled, unacknowledged unicast packets are converted into uni-broadcast messages and sent through the network. All nodes see the message and populate their routing tables accordingly. When the destination node is reached, it sends a route response message via the shortest path. The intermediate nodes see this message and populate their routing tables in the reverse direction, thus re-establishing the route. The default setting is disabled. RF Interface MAC address This parameter is only applicable when the radio is part of a Protected Station. This RF Interface MAC address is used to define the MAC address of the Protection Switch. This address is entered into both Protected Station radios in the factory. If a replacement Protection Switch is installed, the replacement unit MAC address must be entered in both radios (see ‘Replacing a Faulty Protection Switch’ on page 34). The Protection Switch RF Interface MAC address is shown on the Protection Switch label:
134 | Managing the Radio Aprisa SR User Manual CONFIGURATION Save Configuration to USB This parameter saves all user configuration settings to a binary encrypted file on the USB root directory with filename of asrcfg_1.5.3. Some parameters are not saved e.g. security passwords, licence keys etc. Restore Configuration from USB This parameter restores all user configuration settings from a binary encrypted file on the USB root directory with filename of asrcfg_1.5.3. Note: Activating this function will over-write all existing configuration settings in the radio (except for the non-saved settings e.g. security passwords, licence keys etc).
Managing the Radio | 135 Aprisa SR User Manual Events The Events menu contains the setup and management of the alarms, alarm events and traps.

All active alarms for configured alarm events will be displayed on the Parameters page (see ‘Terminal > Parameters’ on page 82). This Switch and Block parameters are only visible / applicable when the radio is part of a Protected Station. Severity The Severity parameter sets the alarm severity. Severity Function Critical The Critical severity level indicates that a service affecting condition has occurred and an immediate corrective action is required. Such a severity can be reported, for example, when a managed object becomes totally out of service and its capability must be restored. Major The Major severity level indicates that a service affecting condition has developed and an urgent corrective action is required. Such a severity can be reported, for example, when there is a severe degradation in the capability of the managed object and its full capability must be restored. Minor The Minor severity level indicates the existence of a non-service affecting fault condition and that corrective action should be taken in order to prevent a more serious (for example, service affecting) fault. Such a severity can be reported, for example, when the detected alarm condition is not currently degrading the capacity of the managed object. Warning The Warning severity level indicates the detection of a potential or impending service affecting fault, before any significant effects have been felt. Action should be taken to further diagnose (if necessary) and correct the problem in order to prevent it from becoming a more serious service affecting fault. Information No problem indicated – purely information
138 | Managing the Radio Aprisa SR User Manual Suppress This parameter determines if the action taken by an alarm. Suppress Function None Alarm triggers an event trap and is logged in the radio Traps Alarm is logged in the radio but does not trigger an event trap Traps and Log Alarm neither triggers an event trap nor is logged in the radio Lower Limit / Upper Limit Threshold alarm events have lower and upper limit settings. The alarm is activated if the current reading is outside the limits. Example: 9 RX CRC Errors The Upper Limit is set to 0.7 and the Duration is set to 5 seconds. If in any 5 second period, the total number of errored packets divided by the total number of received packets exceeds 0.7, the alarm will activate.

Managing the Radio | 207 Aprisa SR User Manual In-Service Commissioning Before You Start When you have finished installing the hardware, RF and the traffic interface cabling, the system is ready to be commissioned. Commissioning the radio is a simple process and consists of: 1. Powering up the radios. 2. Configuring all radios in the FAN using SuperVisor. 3. Aligning the antennas. 4. Testing that the links are operating correctly. 5. Connecting up the client or user interfaces. What You Will Need Appropriately qualified commissioning staff at both ends of each link. Safety equipment appropriate for the antenna location at both ends of each link. Communication equipment, that is, mobile phones or two-way radios. SuperVisor software running on an appropriate laptop, computer, or workstation at the base station radio. Tools to facilitate loosening and re-tightening the antenna pan and tilt adjusters. Predicted receiver input levels and fade margin figures from the radio link budget.
208 | Managing the Radio Aprisa SR User Manual Antenna Alignment A base station omni directional collinear antenna has a vertical polarization. The remote station yagi antennas must also have vertical polarization. Aligning the Antennas Align the remote station yagi antennas by making small adjustments while monitoring the RSSI. The Aprisa SR has a Test Mode which presents a real time visual display of the RSSI on the front panel LEDs. This can be used to adjust the antenna for optimum signal strength (see ‘Test Mode’ on page 26). Note: Low gain antennas need less adjustment in elevation as they are simply aimed at the horizon. They should always be panned horizontally to find the peak signal. 1. Press and hold the ENTER button on the radio LED panel until all the LEDs flash green (about 3 - 5 seconds). Note: The time for the LEDs to display the RSSI result is variable, depending on the network traffic, and can be up to 5 seconds. Small antenna adjustments should be made and then wait for the display to refresh. The RSSI poll refresh rate can be set with the SuperVisor command ‘Transmit Period’ (see ‘Maintenance > Test Mode’ on page 128). 2. Move the antenna through a complete sweep horizontally (pan). Note down the RSSI reading for all the peaks in RSSI that you discover in the pan. 3. Move the antenna to the position corresponding to the maximum RSSI value obtained during the pan. Move the antenna horizontally slightly to each side of this maximum to find the two points where the RSSI drops slightly. 4. Move the antenna halfway between these two points and tighten the clamp. 5. If the antenna has an elevation adjustment, move the antenna through a complete sweep (tilt) vertically. Note down the RSSI reading for all the peaks in RSSI that you discover in the tilt. 6. Move the antenna to the position corresponding to the maximum RSSI value obtained during the tilt. Move the antenna slightly up and then down from the maximum to find the two points where the RSSI drops slightly. 7. Move the antenna halfway between these two points and tighten the clamp. 8. Recheck the pan (steps 2-4) and tighten all the clamps firmly. 9. To exit Test Mode, press and hold the ENTER button until all the LEDs flash red (about 3 – 5 seconds).

Insert the USB flash drive into the Host Port . 4. Using File Transfer, load the software pack into the radio (see ‘Software > File Transfer’ on page 146). 5. Activate the software on the radio (see ‘Software > Manager’ on page 149).
212 | Maintenance Aprisa SR User Manual USB Boot Upgrade Method A single Aprisa SR radio can also be upgraded simply by plugging a USB flash drive containing the new software into the USB A host port on the Aprisa SR front panel and power cycling the radio. Upgrade Process To upgrade the Aprisa SR radio software: 1. Unzip the software release files in to the root directory of a USB flash drive. 2. Check that the SuperVisor USB Boot Upgrade setting is set to ‘Load and Activate’ (see ‘Software > Setup’ on page 145). 3. Power off the Aprisa SR and insert the USB flash drive into the Host Port . 4. Power on the Aprisa SR. 5. The software upgrade process is complete when the OK LED lights solid orange. This can take about 2 minutes. The software will have loaded in to the radio Software Pack location. 6. Remove the USB flash drive from the Host Port . 7. Power cycle the Aprisa SR. Login to the radio being upgraded and go to SuperVisor ‘Software > Manager’ on page 149. The version of the uploaded software will be displayed in the Software Pack ‘Version’ field. If the upgrade process did not start, the Aprisa SR could already be operating on the version of software on the USB flash drive. This will be indicated by flashing OK LED and then the OK, DATA and CPU will light steady green.
Maintenance | 213 Aprisa SR User Manual If the radio is not operating on the new software (after the power cycle), it could be caused by the SuperVisor ‘USB Boot Upgrade’ setting set to ‘Load Only’ (see ‘Software > Setup’ on page 145). In this case, go to SuperVisor see ‘Software > Manager’ on page 149 and tick the Software Pack ‘Activate’ checkbox and click ‘Appy’. If any Display Panel LED flashes red or is steady red during the upgrade process, it indicates that the upgrade has failed. This could be caused by incorrect files on the USB flash drive or a radio hardware failure. Software Downgrade Radio software can also be downgraded if required. This may be required if a new radio is purchased for an existing network which is operating on an earlier software release. The downgrade process is the same as the upgrade process.

216 | Alarm Types and Sources Aprisa SR User Manual 11. Alarm Types and Sources Alarm Types There are three types of alarm event configuration types: 1. Threshold Type These alarm events have lower and upper limits. An alarm is raised if current reading is outside the limits. Note: the limits for PA Current, TX AGC, TX Reverse Power and Thermal shutdown are not user configurable. 2. Error Ratio Type This is the ratio of bad packets vs total packets in the defined sample duration. For Serial, it is the ratio of bad characters vs total characters in the duration seconds. An alarm is raised if current error ratio is greater than the configured ratio. The error ratio is configured in ‘Upper Limit’ field and accepts value between 0 and 1. Monitoring of these events can be disabled by setting the duration parameter to 0. 3. Sample Duration Type Used for No Receive data events type. An alarm is raised if no data is received in the defined sample duration. Monitoring of these events can be disabled by setting the duration parameter to 0.

228 | Product End Of Life Aprisa SR User Manual 13. Product End Of Life End-of-Life Recycling Programme (WEEE) The WEEE Directive concerns the recovery, reuse, and recycling of electronic and electrical equipment. Under the Directive, used equipment must be marked, collected separately, and disposed of properly. 4RF has implemented an end-of-life recycling programme to manage the reuse, recycling, and recovery of waste in an environmentally safe manner using processes that comply with the WEEE Directive (EU Waste Electrical and Electronic Equipment 2002/96/EC). The WEEE Symbol Explained This symbol appears on Electrical and Electronic Equipment (EEE) as part of the WEEE (Waste EEE) directive. It means that the EEE may contain hazardous substances and must not be thrown away with municipal or other waste. WEEE Must Be Collected Separately You must not dispose of electrical and electronic waste with municipal and other waste. You must separate it from other waste and recycling so that it can be easily collected by the proper regional WEEE collection system in your area. YOUR ROLE in the Recovery of WEEE By separately collecting and properly disposing of WEEE, you are helping to reduce the amount of WEEE that enters the waste stream. One of the aims of the WEEE directive is to divert EEE away from landfill and encourage recycling. Recycling EEE means that valuable resources such as metals and other materials (which require energy to source and manufacture) are not wasted. Also, the pollution associated with accessing new materials and manufacturing new products is reduced. EEE Waste Impacts the Environment and Health Electrical and electronic equipment (EEE) contains hazardous substances which have potential effects on the environment and human health.
