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 packet data and Ethernet data between the Base Station, Repeater Stations and Remote Stations. The Aprisa SR is configurable as a point-to-multipoint Base Station, a Remote Station or a Repeater Station. Aprisa SR User Manual 16 | About the Radio 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 Base Stations are fitted with omni-directional antennas and the Remote Stations use directional Yagi antennas for higher gain. On start-up the Base Station transmits a registration message which is recognized by the Remote Stations which respond with their own registration message. This allows the Base Station to record the details of all the Remote Stations active in the network. 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 the Remote Stations, within the coverage area, will receive the messages broadcast from the Base Station, but only the radio the message is intended for will action the message. 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. The Aprisa SR network is not designed for Remote Stations to communicate with other Remote Stations. Aprisa SR User Manual About the Radio | 17 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.

Aprisa SR User Manual About the Radio | 19 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 which consists of base station controlled scheduling with remote station access using an access request / access grant (AR/AG) scheme. Aprisa SR User Manual 20 | About the Radio 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. There are a number of parameters that can be altered for the channel access such as back off times, number of retries etc. To enable the most efficient use of the channel these parameters will differ for each network (largely dependent on number of radios in the network). 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. Aprisa SR User Manual About the Radio | 21 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 serial port is terminated on a serial port and data originating on an Ethernet port is terminated on an Ethernet port only. User Traffic User traffic is prioritized depending on the Serial and Ethernet Data Priority options (see ‘Serial > Advanced’ on page 91 and ‘Ethernet > Advanced’ on page 98). 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 has the same priority as Ethernet User Traffic but if the radio is not licensed for Ethernet, the Ethernet Data Priority is set to Low.

Aprisa SR User Manual Diagnostics Function Active 26 | About the Radio 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 115 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). Note: 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. Aprisa SR User Manual Product Options | 27 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. Option Example Part Number Single Antenna Port APSR-N400-012-SO-12-ETAA Dual Antenna Port APSR-N400-012-DO-12-ETAA Aprisa SR User Manual 28 | Product Options Protected Station The Aprisa SR Protected Station provides radio and user interface protection for Aprisa SR radios when configured as a Base Station. 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. Option Example Part Number Aprisa SR Radio APSR-N400-012-SO-12-ETAA Aprisa SR Protected Station APSR-R400-012-SO-12-ETAA The Aprisa SR Protected Station is comprised of an Aprisa SR Protection Switch and two standard Aprisa SR radios. 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. The active radio sends regular ‘keep alive’ messages to the standby radio to indicate it is 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). Aprisa SR User Manual Product Options | 29 Configuration Management The active and standby radios are separately managed by SuperVisor via the Local and Partner IP addresses. Changes to the configuration in one radio must be reflected in the partner radio. Changes to the Network Table are automatically synchronized from the active radio to the standby radio but 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. This guard time will block another switch over with 20 seconds of the previous switch over. At the end of the guard time period, the switching criteria will be evaluated and any protection switch will occur immediately if necessary. 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 126). PA current Tx AGC Tx reverse power Temperature threshold Thermal shutdown RSSI threshold Rx CRC errors RF no receive data Ethernet port 1 – no receive data Ethernet port 1 – data receive errors Ethernet port 1 - data transmit errors Ethernet port 2 – no receive data Ethernet port 2 – data receive errors Ethernet port 2 - data transmit errors Serial port – no receive data Serial port – data receive errors Component failure Calibration failure Configuration not supported Switch over will not occur if there is a power failure or an active alarm event is detected on the standby radio which has been configured as a ‘blocking criteria’. Switch over will be initiated once either of these conditions is rectified, i.e. power is restored or the alarm is cleared. Aprisa SR User Manual 30 | Product Options 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 lock is indicated by the three LEDs on the Protection Switch: A LED Orange Manual Lock asserted and radio A is active B LED Orange Manual Lock asserted and radio B is active Auto LED Green Manual Lock is in Auto position Only one of three LEDs will be active at a time. The Protection Switch also has a Software Manual Lock (see ‘Lock Active’ on page 119). 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 reevaluated 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 220 Ω pullup to +5 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 143). Aprisa SR User Manual Product Options | 31 Installation Mounting The Aprisa SR Protected Station is designed to mount in a standard 19 inch rack.

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 Data Driven 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 The active radio is determined explicitly by which radio receives data on its RS-232 serial port input from the interface. The active radio carries all RS-232 serial traffic over its radio link and the standby radio is unused with its transmitter turned off. If data is received on the RS-232 serial port interface input of the standby radio, it will immediately become the active radio and the radio which was active will become the standby radio. Aprisa SR User Manual 36 | Product Options Switch Over The active radio is determined explicitly by which radio receives data on its RS-232 serial port. The switching and blocking criteria used for the standard Protected Station do not apply. This means that events and alarms on the unit are not used as switching criteria.

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. Aprisa SR User Manual 44 | Preparation 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 Aprisa SR User Manual Preparation | 45 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 Aprisa SR User Manual 46 | Preparation 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. Note: 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. Aprisa SR User Manual Preparation | 47 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. Aprisa SR User Manual 48 | Preparation 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.

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, 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: Manage the entire FAN (Field Area Network) from the Base Station connection. View and set standard radio configuration parameters, including frequencies, transmit power, channel access, serial, Ethernet and USB port settings. Set radio operating mode, whether Base Station, Remote Station or Repeater Station. Set and view security parameters. Display performance and alarm information, including RSSI, alarm status, time-stamped events, and alarm parameters. 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: Set up your PC for a compatible IP address e.g. 169.254.50.1 with a subnet mask of 255.255.0.0. Connect your PC network port to one of the Aprisa SR Ethernet ports. Open a browser and enter http:// 169.254.50.10. Login to the radio with the default Username ‘admin’ and Password ‘admin’. Change the IP address to conform to the network plan in use. Aprisa SR User Manual 58 | Managing the Radio 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. Aprisa SR User Manual Managing the Radio | 59 PC Settings for SuperVisor To change the PC IP address: If your PC has previously been used for other applications, you may need to change the IP address and the subnet mask settings.

Enter the TX frequency and the RX frequency and then click ‘Save’. This is to prevent remote management communication from being lost before both frequencies have been changed in the Remote Stations. TX and RX Frequencies. The TX and RX frequencies entered must be within the frequency tuning range of the product frequency band and will be automatically resolved to the synthesizer step size for the frequency band e.g. an ETSI 400 MHz band frequency entry of 458,004,000 Hz will be changed to 458,006,250 Hz (see ‘Frequency Bands’ on page 148). The default setting is 400,000,000 Hz. The TX and RX frequencies can be single frequency ½ duplex or dual frequency ½ duplex. Dual frequency ½ duplex is often used for reasons of: Channel Planning. Network Efficiencies. Regulatory rules. Aprisa SR User Manual 80 | Managing the Radio Single Frequency Operation The TX and RX frequencies of the Base Station, Repeater Station and all the Remote Stations are on the same frequency. To change the TX and RX frequencies: Change the TX and RX frequencies of the Remote Stations operating from the Repeater Station to the new frequency. The radio links to these Remote Stations will fail. Change the TX and RX frequencies of the Repeater Station operating from the Base Station to the new frequency.

For all the Remote Stations operating from the Base Station, change the TX frequency to frequency A and the RX frequency to frequency B. Aprisa SR User Manual Managing the Radio | 83 Transmit power The transmitter power is the power measured at the antenna output port when transmitting. The transmitter power has a direct impact on the radio power consumption (see ‘Power Consumption’ on page 153) and ‘Save’ the change. The default setting is +37 dBm. Note: The Aprisa SR transmitter contains power amplifier protection which allows the antenna to be disconnected from the antenna port without product damage. Aprisa SR User Manual 84 | Managing the Radio Radio > Channel Access CHANNEL ACCESS Access Mode This parameter sets the Media Access Control (MAC) used by the radio for over the air communication. Access Mode Function Access Request This mode is a general purpose access method for high and low load networks Listen Before Send This mode is optimised for low load networks and repeated networks The default setting is Access Request. 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. Aprisa SR User Manual Managing the Radio | 85 Note that this includes the wireless protocol header (18 to 20 Bytes) and security payload (0 to 16 Bytes). The length of the security header depends on the level of security selected. An example wireless protocol frame structure is illustrated below. This uses maximum security of 16 Bytes. The length of the header varies depending on whether the user data must be segmented. User data will be segmented if it is larger than the wireless packet payload length. In this case, this limit is 213 Bytes. If the user data packet is larger than this, then the header increases to 20 Bytes to account for the transport of the required segmentation and reassembly data. Note that 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 parameter sets the time a packet is allowed to live in the system before being dropped if it cannot be transmitted over the air. The default setting is 5000 ms. ACCESS REQUEST Maximum Access Attempts This parameter sets the maximum number of attempts the MAC will try to acquire the channel for the packet to be transmitted before it is dropped. The default setting is 3. Maximum Back-Off Count This parameter sets the random back-off period before the MAC tries to acquire the channel to transmit a packet. The default setting is 4. Aprisa SR User Manual 86 | Managing the Radio LISTEN BEFORE SEND When the Access Mode is set for Listen Before Send, the Listen Before Send parameters can be set: Network Type This parameter sets the operating mechanism used in the FAN: Network Type Function Polled The SR radio network is part of a polling system e.g. if a SCADA master station is set up to periodically poll remote terminal units (RTUs). Channel access for data traffic in this case is completely controlled by the external SCADA master. Exception The Base Station and all remote and Repeater Stations can send traffic asynchronously. The default setting is Polled. All Channel Access parameters are calculated and set automatically for the network topology and the size of packet that is being transmitted. This improves channel utilization if there are variable size packets on the network. When the Network Type is set for Exception, the Access Rate and Network Size parameters can be set: Access Rate This parameter defines the rate at which the channel is accessed by remote or Repeater Stations. It is an approximation of the traffic rates on the FAN. The default setting is 1 per min. Aprisa SR User Manual Managing the Radio | 87 Network Size This parameter defines the number of scope of the FAN e.g. 2-10 Remotes. This enables the Channel Access parameters to be optimized for the network topology. The default setting is 1 remote. 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. Aprisa SR User Manual 88 | Managing the Radio Serial Serial > Summary SUMMARY This page displays the current settings for the Serial interface parameters. Aprisa SR User Manual Managing the Radio | 89 Serial > General SERIAL PORT SETTINGS Baud Rate (bit/s) The baud rate can be set to 300, 1200, 2400, 4800, 9600, 19200, 38400, 57600 or 115200 bit/s. The default setting is 115200 bit/s. Character Length (bits) The character length can be set to 7 or 8 bits. The default setting is 8 bits. Parity The parity can be set to Even, Odd or None. The default setting is None. Stop Bits (bits) The stop bits can be set to 1 or 2 bits. The default setting is 1 bit. 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. Aprisa SR User Manual 90 | Managing the Radio Serial > Flow Control CTS / RTS Status The CTS / RTS Status can be set to enabled or disabled. The default setting is Disabled. CTS / RTS Status Function Enabled CTS / RTS hardware flow control between the DTE and the Aprisa SR radio port (DCE) is enabled. 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. Disabled The Aprisa SR radio port (DCE) CTS is in a permanent ON (+ve) state. This does not go to OFF if the radio link fails. Aprisa SR User Manual Managing the Radio | 91 Serial > Advanced SERIAL SUPPORT Serial Data Mode The Serial Data Mode can be set to Enabled or Disabled. The default setting is Enabled. Serial Data Mode Function Enabled Enables serial data communication over the radio link. Disabled Disables serial data communication over the radio link. Serial Data Priority The Serial Data Priority controls the priority of the serial traffic relative to the Ethernet traffic. If equal priority is required to Ethernet traffic, this setting must be the same as the Ethernet Data Priority setting. 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.

These settings are the same as setting the parameters in ‘Terminal > Device’ on page 74. Aprisa SR User Manual 96 | Managing the Radio Ethernet > L2 Filtering FILTER DETAILS L2 Filtering provides the ability to filter radio link traffic based on specified Layer 2 MAC addresses. Traffic originating from specified Source MAC Addresses destined for specified Destination MAC Addresses that meets the protocol type criteria will be transmitted over the radio link. Traffic that does not meet the filtering criteria will not be transmitted over the radio link. If the Source MAC Address is set to ‘FF:FF:FF:FF:FF:FF’, traffic will be accepted from any source MAC address. If the Destination MAC Address is set to ‘FF:FF:FF:FF:FF:FF’, traffic will be delivered to any destination MAC address. Protocol Type This parameter sets the Ethernet Type accepted ARP, VLAN, IPv4, IPv6 or ANY type. Example: In the screen shot, the rules are configured in the Base Station which controls the radio link traffic from Base Station to remote / Repeater Stations. Traffic from a device with the MAC address 00:01:50:c2:01:00 is forwarded over the radio link if it meets the criteria: Rule 1 If the Ethernet Type is ARP going to any destination MAC address or Rule 2 If the Ethernet Type is ANY and the destination MAC address is 01:00:50:c2:01:02 or Rule 3 If the Ethernet Type is VLAN tagged packets going to any destination MAC address Aprisa SR User Manual Managing the Radio | 97 Special L2 Filtering Rules: Unicast Only Traffic This L2 filtering allows for Unicast only traffic and drop broadcast and multicast traffic. This filtering is achieved by adding the two rules: Rule Source MAC Address Destination MAC Address Allow ARPS FF:FF:FF:FF:FF:FF FF:FF:FF:FF:FF:FF ARP Allow Unicasts from ANY source FF:FF:FF:FF:FF:FF FE:FF:FF:FF:FF:FF ANY Aprisa SR User Manual Protocol Type 98 | Managing the Radio Ethernet > Advanced This screen is only available if the Ethernet traffic option has been licenced (see ‘Maintenance > Licence’ on page 120). ETHERNET SUPPORT There must always be an Ethernet port available for management, so both Ethernet ports cannot be set to User Only. Ethernet Port 1 Function This parameter sets the use for the Ethernet port 1. The default setting is Management Only. Ethernet Port Function Function Management Only The Ethernet port is only used for management of the FAN. Management and User The Ethernet port is used for management of the FAN and User traffic over the radio link. User Only The Ethernet port is only used for User traffic over the radio link.

Ethernet Port Function Function Management Only The Ethernet port is only used for management of the FAN. Management and User The Ethernet port is used for management of the FAN and User traffic over the radio link. User Only The Ethernet port is only used for User traffic over the radio link. This option is not available if this radio is part of a Protected Station. Aprisa SR User Manual Managing the Radio | 99 Ethernet Data Priority The Ethernet Data Priority controls the priority of the Ethernet traffic relative to the serial traffic. If equal priority is required to serial traffic, this setting must be the same as the Serial Data Priority setting The Ethernet 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 Ethernet buffer is 10 Ethernet packets (1 packet can be up to Ethernet MTU, 1500 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. L2 Filter This parameter enables / disables L2 Filtering. The default setting is disabled. If L2 Filtering is enabled, the filters defined in Ethernet > L2 Filtering become active. If L2 Filtering is disabled, the filters defined in Ethernet > L2 Filtering have no effect.

Aprisa SR User Manual 106 | Managing the Radio 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 107). To access the Remote / Repeater Stations, 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 69). Aprisa SR User Manual Managing the Radio | 107 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.

Aprisa SR User Manual Managing the Radio | 119 SOFTWARE MANUAL LOCK The software Manual Lock is a software implementation of the Hardware Manual Lock switch on the Protection Switch. The Software Manual Lock is intended to be used when making changes to the Protected Station remotely via SuperVisor, to prevent the Protected Station from switching as a result of the changes being made. See ‘Setting the Software Manual Lock’ on page 33 for a recommended process to follow to make remote configuration changes. Lock Active To This parameter sets the Protection Switch Software Manual Lock. The Software Manual Lock only operates if the Hardware Manual Lock is deactivated (set to the Auto position). Option Function Automatic The protection is automatic and switching will be governed by normal switching and blocking criteria. Primary The primary radio will become active i.e. traffic will be switched to the primary radio. Secondary The secondary radio will become active i.e. traffic will be switched to the secondary radio. Warning: If the Software Manual Lock is set to Primary or Secondary, the Software Manual Lock must be set to the same value on both Protected Station radios. If the Software Manual Lock is set to primary on one radio, and secondary on the other radio, management communication to the radios may be lost if both radios become set to 'standby' mode. Aprisa SR User Manual 120 | Managing the Radio 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.

Feature Licences Feature Licences 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 93). Remote Management and SNMP management In this software version, Remote Management and SNMP management are enabled by default. Aprisa SR User Manual Managing the Radio | 121 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. 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 reregister. 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. Aprisa SR User Manual 122 | Managing the Radio 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 reestablishing the route. The default setting is enabled. 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: Aprisa SR User Manual Managing the Radio | 123 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_1.3.4. 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_1.3.4. 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). Aprisa SR User Manual 124 | Managing the Radio Events There are two types of events that can be generated on the Aprisa SR radio. These are: 1. Alarm Events Alarm Events are generated to indicate a problem on the radio. 2. Informational Events Informational Events are generated to provide information on key activities that are occurring on the radio. These events do not indicate an alarm on the radio and are used to provide information only. See ‘Alarm Types and Sources’ on page 144 for a complete list of events. Events > Alarm Summary ALARM SUMMARY The Alarm Summary is a display tree that displays the current states of all radio alarms. The alarm states refresh automatically every 12 seconds. LED Colour Severity Green No alarm Orange Warning alarm Red Critical, major or minor alarm Aprisa SR User Manual Managing the Radio | 125 Events > Event History EVENT HISTORY The last 1500 events are stored in the radio. The complete event list can be downloaded to a USB flash drive (see ‘Write Alarm History to USB’ on page 112).

Aprisa SR User Manual 126 | Managing the Radio Events > Events Setup EVENTS SETUP Alarm event parameters can be configured for all alarm events (see ‘Alarm Events’ on page 144). 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 Aprisa SR User Manual Managing the Radio | 127 Suppress The Suppress 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. Units (1) The Units parameter shows the unit for the Lower Limit and Upper Limit parameters. Duration The Duration parameter determines the period to wait before an alarm is raised if no data is received. Units (2) The Units parameter shows the unit for the Duration parameters. Switch The Switch parameter determines if the alarm when active causes a switch over of the Protection Switch. This parameter is only applicable when the radio is part of a Protected Station. Block The Block parameter determines if the alarm is prevented from causing a switch over of the Protection Switch. This parameter is only applicable when the radio is part of a Protected Station. The Next button will display the next page of 8 alarm events and the Prev button will display the previous page of 8 alarm events.

Aprisa SR User Manual Maintenance | 139 9. Maintenance There are no user-serviceable components within the radio. All hardware maintenance must be completed by 4RF or an authorized service centre. Do not attempt to carry out repairs to any boards or parts. Return all faulty radios to 4RF or an authorized service centre. For more information on maintenance and training, please contact 4RF Customer Services at support@4rf.com. CAUTION: Electro Static Discharge (ESD) can damage or destroy the sensitive electrical components in the radio. Aprisa SR User Manual 140 | Maintenance Radio Software Upgrade The Aprisa SR radio software can 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. The software upgrade procedure is different for an Aprisa SR Protected Station (see ‘Protected Station Software Upgrade’ on page 32). Note: If a radio has been configured for a Protection Type of ‘Redundant’ (see ‘Terminal > Protection’ on page 77), and that radio is no longer part of a Protected Station, the Protection Type must be changed to ‘None’ before the radio software upgrade can be achieved. Upgrade Process To minimize disruption of link traffic and prevent your radios from being rendered inoperative, please follow the procedures described in this section together with any additional information or instructions supplied with the upgrade package. The radio software must be identical on all radios in the FAN. To upgrade the Aprisa SR radio software: 1. Check that the SuperVisor USB Upgrade setting is set to ‘Enabled’ (see ‘Maintenance > Upgrade’ on page 114). 2. Unzip the software release files in to the root directory of a USB flash drive. 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 Standby SW location. 6. Remove the USB flash drive from the Host Port 7. Power cycle the Aprisa SR. Login in to the radio being upgraded and view the Active and Standby SW version (see ‘ Summary’ on page 70). If the upgrade process was successful, the Active SW Version will show the new software version and the Standby SW Version will be shown as ‘No Standby’. 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. Aprisa SR User Manual Maintenance | 141 If the radio is not operating on the new software (after the power cycle), it could be caused by the SuperVisor USB Upgrade setting set to ‘Authenticate’ (see ‘Maintenance > Upgrade’ on page 114). The new software will have uploaded in to the Aprisa SR but will not have activated. The new software version will be displayed in the Standby SW version. In this case, go to SuperVisor ‘Maintenance > Upgrade’ on page 114 and tick the ‘Switch to new Software’ checkbox and click ‘Save’ to apply the changes. 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. To view the uploaded software version: Select Terminal Settings > Terminal > Summary The version of the uploaded software will be displayed in the ‘Standby SW Version field. 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. Aprisa SR User Manual 142 | Interface Connections 10.

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 Communications 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.
