To meet the requirements of FCC part 2.1091 for radio frequency radiation exposure, this radio must be used in such a way as to guarantee at least 20 cm between the antenna and users. Greater distances are required for high-gain antennas. The FCC requires a minimum distance of 1 mW *cm2 power density from the user (or 20 cm, whichever is greater). If a specific application requires proximity of less than 20 cm, the application must be approved through the FCC for compliance to part 2.1093.

RLX2 Series ♦ 802.11a, b, g, n RLX2 Quick Setup Industrial Hotspots User Manual 2 RLX2 Quick Setup In This Chapter  Setup Master Radio ............................................................................... 20  Setup Repeater Radio ........................................................................... 26  Setup Client Radio ................................................................................ 28 This section describes how to setup RLX2 radios in a minimal configuration before deploying them in the permanent installation. It will help verify the radios are operational along with getting familiar with basic configuration procedures. Note that the procedures described in this section assume the radios are in their default configurations as shipped by ProSoft. If that is not the case, reset the radios to factory defaults as described in section 6.7 before attempting these procedures. In any given network, there must be one radio acting as a Master, and the other radios will be configured as Repeaters or Clients. Generally there is only one Master radio per network. Note: The RLX2 radios support the Rapid Spanning Tree Protocol (RSTP) which allows configuration of multiple Master radios on a single network in “hot standby” mode for redundancy. RSTP is described further in section 6.2.3 Because most wireless networks consist of one Master radio and multiple Repeaters, all RLX2 radios are shipped from ProSoft pre-configured as Repeaters. Hence our first task is to configure one radio as the network Master. IMPORTANT: If a ProSoft Power adapter RL-PS007-2 (supplied with the RLX-IHBTK Bench Test Kit) is not present, see section 8.5.1 for instructions on wiring the power connector.

RLX2 Quick Setup RLX2 Series ♦ 802.11a, b, g, n User Manual Industrial Hotspot 2.1 Setup Master Radio The first step is to select the radio to use as a Master. Typically all RLX2 radios in a network will be the same model, although this is not necessary. IMPORTANT: The only RLX2 radios that do not have any channels in common with each other are the RLX2-IHA and RLX2-IHG. The RLX2-IHW and RLX2-IHNF radios can communicate with each other and with the RLX2-IHA and RLX2-IHG radios. If all the radios are present on the workbench, antennas are not needed for this configuration exercise. Radios without antennas will have sufficient signal strength to link over short distances, without radiating or receiving unnecessary RF energy in the surrounding environment. The connections needed are on the bottom of the radio: 1. Attach an Ethernet cable to the designated master RLX2 radio. Make sure this network connection is on the same subnet as the PC running the IH Browser configuration software. Note: The Ethernet DATA LED should come on when data is sent or received from the radio. The Ethernet SPEED LED indicates the speed of the Ethernet connection. The SPEED LED is off for 10 Base T, on for 100 Base T, and blinks about once every two seconds for 1000 Base T links. 2. Power up the radio. The power LED should illuminate with an amber color, then go out for a few seconds during initialization, then finally come back on green. This process will take 10 to 15 seconds. Once the power LED is green, the radio has booted and is operational. Other LEDs may become active as well. 3. Take note of the MAC address of the RLX2 radio. This is printed on a label attached to the front of the radio. The MAC address should be something like 00-0D-8D-XX-YY-ZZ (e.g. 00-0D-8D-F0-5C-8E.) This number uniquely identifies the radio on the network. Page 20 of 161 ProSoft Technology, Inc. November 29, 2012

Attach power to another RLX2 radio. The Ethernet cable does not need to be attached to it at this time. 2. After the radio is booted, the radio should appear in the IH Browser: Note that the Repeater radio above (whose MAC address ends in BF in the above example) has linked to the Master (whose MAC address ends in BE) and there is a signal strength indication of –85 dBm. 3. Attach an Ethernet cable, and assign a unique IP address to the Repeater. In this example, the Repeater is assigned an IP address of 192.168.1.251: After setting the Repeater’s IP address, remove its Ethernet connection. Page 26 of 161 ProSoft Technology, Inc.

RLX2 Quick Setup RLX2 Series ♦ 802.11a, b, g, n User Manual Industrial Hotspot 2.3 Setup Client Radio RLX2 radios can be configured in Client mode. Client mode radios only support one wired network device, but can connect to third-party 802.11 Access Points. The following table highlights the most significant differences between Repeater and Client modes on RLX2 radios: Repeater Client Number of attached Ethernet devices supported Many (up to limits of network) One Can connect to other RLX2 Repeaters? Yes No Can connect to non-ProSoft Access Points (Masters)? No Yes MAC address seen on network Repeater radio’s MAC address MAC address of connected device, or user-specified MAC address. Client mode radios are not often necessary in Industrial network applications. If the need for a Client RLX2 radio in the system is not needed, this example configuration can be skipped. The most straightforward way to test a Client mode radio configuration is with a second PC connected as the downstream network device from a Client radio. We will assume such a setup in the following example, and will connect to the Master radio we configured previously. Page 28 of 161 ProSoft Technology, Inc. November 29, 2012

Assign it an IP address as described above. Open the configuration webpage and change the radio to Client mode as shown: Click Apply Changes. When the radio reboots, the IH Browser will display: 2. Power off the Client radio and disconnect the Ethernet cable from the configuration PC. 3. Connect the Ethernet cable to an Ethernet port on another PC, and power up the Client radio. (The radio must be powered up after attaching the Ethernet cable to the new PC so the radio will register the MAC address of the PCs network interface.) ProSoft Technology, Inc.

RLX2 Series ♦ 802.11a, b, g, n Planning the Network Industrial Hotspots User Manual 3 Planning the Network Before configuring and installing the wireless network, it may help to create a plan. The following points assume a bridge network of masters and repeaters. Clients can also be configured to work with devices on existing wireless LANs. For information, see Setup Client Radio (page 28). The simplest way to design the physical network of radios, antennas, connectors, cables, amplifiers and other accessories, is to use ProSoft Wireless Designer (page 32). This is a freely-available software application that determines the hardware needs based on the user’s answers to a few questions. The software will generate a Bill of Materials specifying all the components needed for the installation. ProSoft Wireless Design is included on the optical media supplied with the RLX2 radio, and is also available for downloading from the ProSoft website.  To begin, identify the potential radio locations. For example, the master radio may be installed near a PC in a central plant location (This PC can configure the radios through the Radio Configuration / Diagnostic Utility). If the plant is an oil refinery, for example, radios may need to be installed near the oil tanks.  The next important issue is how to link the radios. Unless the radios are very close together, make sure that each pair of radio antennas in the network has a line of sight between them. In other words, visibility is needed from one antenna to another, either with the naked eye or with binoculars.  If a line of sight does not exist between antennas, an additional site is needed for installing a repeater radio. This site will create a bridge between the radio antennas.  Choose the appropriate antennas for the network. If an antenna will be connected to the radio by a long cable, a power amplifier (available from ProSoft Technology) may be needed. The more distance between an antenna and its radio, the more signal loss the radio will have. ProSoft Wireless Designer can suggest suitable antennas for the application based on frequency band, data rate, distance, power output level, and other factors.  Consider drawing up the network plans on paper. As part of the drawing, assign a logical name to each radio. These names can be assigned in the Radio Configuration / Diagnostic Utility.  As part of the planning, a site survey may be helpful. ProSoft Technology can perform this survey, or hire a surveyor, or survey it on your own.  Protect radios from direct exposure to weather, and provide an adequate, stable power source. Make sure the plan complies with the radio’s power requirements and cable specifications. Important: Radios and antennas must be located at least 8 inches (20 cm) away from personnel.

Planning the Network RLX2 Series ♦ 802.11a, b, g, n User Manual Industrial Hotspot 3.1.1 Installation Questions The following questions will help in getting familiar with the system. How many radios are in the network? Master ID: Repeater ID: Client ID: Locations: Is there a Line of Sight between them? What type of antennas will be used in the network? 3.1.2 Planning the Physical Installation A network's performance is affected by attributes specific to the installation site. Consider the following cautions, where possible, to optimize the network installation:  Design the network to use less than 2048 radios (per network)  Place radios within the specified 15 miles of each other  Add repeater to extend distance or where line of sight is limited  Radios or antennas CANNOT be placed within 8 inches (20 cm) of where people will be Though radio frequency communication is reliable, sometimes its performance can be affected by intangibles. A good network installation plan includes time and resources for performance testing and installation changes. Test the installation plan (page 39) before the network installation is complete.

If feasible, test with the radios and end-device equipment together before they are installed in the field. Important: If the radios are close enough to each other that their received signal strength is greater than -40dBm, performance may be degraded. Disconnect antennas from radios during bench testing, or move the radios further apart from each other. Tip: To make it easier to physically identify the radios, apply a label to each radio indicating the radio name and IP address. After each radio is configured using the IH Browser and the web configuration form, install the radios and test their performance. Install the radios in their proposed permanent locations. Temporarily place each radio’s antenna near its proposed mounting location. The temporary placement of the antenna can be done by hand. Make sure to monitor the radio’s signal strength.

RLX2 Series ♦ 802.11a, b, g, n Installing the Radios Industrial Hotspots User Manual 4.1 Connecting antennas Each radio must have an antenna connected to the Main antenna port on the RLX2 radio; without an antenna for each radio, the network will not function if the radios are more than a few meters apart. All antennas for radios that communicate directly with each other should be mounted so they have the same antenna polarity. Small antennas with a reverse-polarity SMA connector can be mounted directly on the radio. Screw the antenna onto the antenna port connector until it is snug. Larger antennas and antennas that do not have a reverse-gender SMA connector must be mounted separately and connected to the radio using a coaxial antenna cable. Because the antenna cable attenuates the RF signal, use an antenna cable length that is no longer than necessary to ensure optimum performance. Important: If the radio is to be used in a hazardous location, the radio must be mounted in an enclosure approved for hazardous locations. The radio requires a separate cable connection to the SMA connector that leads to an internal antenna. 4.2 Test the Network Installation Plan Test proposed installations before finalizing the installation. After the network and radios are configured:  Install the Master radio in its proposed permanent location  Cable the Configuration PC to the Master radio  Place the Remote radios in their proposed locations  Temporarily place each radio's antenna near its proposed mounting location. The temporary placement of the antenna can be by hand. However, one person must hold the antenna while the other person monitors the Remote radio's signal strength displayed on the Configuration PC. To improve the signal quality of each Remote radio:  Increase the height of the antenna's placement  Use higher-gain antennas  Increase the radio's transmission power, cable the radio to the Configuration PC, and reconfigure it  Select a new location for the Remote radio and/or its antenna  Decrease the length of antenna cable  Determine and resolve sources of "electrical" noise which may be interfering with the radio transmission  Add a repeater between the radios that are not communicating, or reconfigure an existing radio as a repeater if line of sight is available ProSoft Technology, Inc.

This error occurs when the IH Browser attempts to scan for radios and no valid network connection exists on the PC, wired or wireless. To correct this error, Confirm the PC has at least one active network (LAN) connection. It could be a wired Ethernet connection or a wireless 802.11 connection. Confirm the network connection has a valid IP address. The network connection might need to have a static IP address assigned to it. Check the IP address of the network connection to determine that one has been assigned. 5.6 Troubleshoot Missing Radios If radios are not visible in the IH Browser, try the following:  First, click the SCAN button again. Scans are sent as broadcast messages, which can be dropped in RF connections, requiring the user to scan again.  Second, disable any software firewall running on the PC (This is most common in Windows XP and newer). Open the NETWORK CONNECTIONS folder in the Windows Control Panel, then open the LOCAL AREA CONNECTION PROPERTIES window and verify that the check box under INTERNET CONNECTION FIREWALL is not checked.  If the preceding approaches do not help, the PC running the IH Browser and the radios are probably not connected to the same local network. Verify the connections.  In topological view, any unlinked radios may be at the bottom of the window. Scroll down to see all radios. If the radios still cannot be seen in the IH Browser, call technical support. Page 46 of 161 ProSoft Technology, Inc. November 29, 2012

RLX2 Series ♦ 802.11a, b, g, n Detailed Radio Configuration / Diagnostics Industrial Hotspots User Manual Field Description 802.11 Mode Present only on the RLX2-IHNF radio. There are three possible mode settings: 802.11a/g The radio acts as an 802.11a radio on the 5 GHz band, and an 802.11g radio on the 2.4 GHz band. Data rates will be limited to the 802.11 a/g rates (54 mbps maximum). 802.11n operational features will be disabled. It is not necessary to select this mode for RLX2-IHNF radios to link to other RLX2 or RLXIB series radios; they will link their best possible speeds regardless of mode. This mode is not commonly used. It is mainly used to allow 802.11 a/b/g client devices that cannot link to 802.11n devices to work. One example of such a device is the ProSoft 1734-AENTR wireless I/O client. 802.11n Default operational mode of the RLX2-IHNF radio. All 802.11n features are operational, and 20 MHz wide channels are used. 802.11.n wide Utilizes adjacent pairs of 20 MHz-wide channels as a single 40 MHz-wide channel. This allows the fastest data throughput to other 802.11n devices. Only 802.11n devices can utilize this mode, but all RLX2 radios will link at their best speed regardless of mode. Channels in the 5 GHz band are 20 MHz apart, so 802.11n wide mode occupies only two channels in that band. However, channels in the 2.4 GHz band are spaced only five MHz apart, so 802.11n wide mode in the 2.4 GHz band occupies eight adjacent channels! Since there are at most 13 channels in the 2.4 GHz band, and only three channels do not overlap others, it is not recommended to enable wide mode on 2.4 GHz band channels. Channel list (master radio) Indicates the channel number as well as the frequency for operation in the 2.4 GHz or 5 GHz bands. The available channels in the radio will vary based on the model and country configuration. Please see section 0 for a comprehensive list of all frequencies for all RLX2 radio models. RLX2-IHNF radios can operate on 5 GHz frequencies that are subject to Dynamic Frequency Selection regulations, and have a special channel selection called DFS Auto Select. See section 6.8.2 for further details Important: When choosing an antenna for use with the RLX2 radio, make sure it supports the frequency range set in the configuration for the radio. Repeater Configures a radio as a repeater. The repeater mode is the normal radio mode for the network, while the master mode is more of a special setting to establish the network channel and define the root of the network tree. Repeater radios help extend the range of a network and help create the signal "bridges" that allow networked radios to communicate. All RLX2 radios are capable of repeating.

In the example above, the Repeater is not linked to a Master radio so the Parent MAC is shown as all zeroes. Parent Selection Method Automatically Choose Best The Automatic Parent Selection algorithm uses a calculation to create a “cost” metric for each possible parent radio that it detects. In the calculation the radio includes,  RSSI - Stronger signals receive a lower cost.  Hop Count - Fewer hops from the Master radio is given preference and therefore a lower cost Choose this setting to allow the radio to determine the best parent to select. Parent Branch Length RLX2 radio will choose its parent strictly by the number of repeaters between it and the Master radio. If a Branch Length of 1 is chosen, the RLX2 radio will link only to the Master radio. If a Branch Length of 2 is chosen, the RLX2 radio will link only to another RLX2 radio that is linked to the Master radio, and so on. ProSoft Technology, Inc. Page 61 of 161 November 29, 2012
Detailed Radio Configuration / Diagnostics RLX2 Series ♦ 802.11a, b, g, n User Manual Industrial Hotspot Field Description Preferred Parent RLX2 radio will select its parent from a list of possible parents specified by the user. The user can list up to eight radios to choose from.  Best in List When Best in List is selected the radio will select its parent using the "Automatic Parent Selection" algorithm, but it will limit the selection to the list of radios in the list. Therefore, the radio in the list with the lowest cost according to the algorithm will be chosen as its parent.  Follow List Priority When Follow List Priority is chosen the radio will select its parent from the list giving preference to the 1st entry followed by the 2nd entry and so on. Parent Selection Parameters Signal Strength Threshold When the signal from a parent reaches a high enough value, a stronger signal will not improve the quality of the link any further. For signals that are above that threshold, only fewer hops from the Master give preference. The threshold can be adjusted here. Rate to Parent The default setting is Auto which allows the radio to select the best rate to use to the parent radio, and adapt over time. Specify a fixed rate rather than auto for example if the link to the parent has a low signal strength in which case fixing a lower rate can improve performance. The actual rate used between this radio and its parent is the lower value of this setting and the Max Data Rate setting in the parent (see Max Data Rate). So use these two controls in conjunction if desired to tailor the rate of each parent link. Roaming Parameters Optimize Fast Roaming Parameters In typical Fast Roam applications a Repeater is installed on a mobile pallet or platform and a set of Master units forms a backbone infrastructure network, through which the Repeater must roam. To obtain fast roam times, Spanning Tree must be disabled and SSID's not hidden on the Master. The Repeater should be configured to not allow child Repeaters and to use a Signal Strength Threshold set high enough such that RSSI is used to determine the link cost to a parent. Checking the checkbox in this section automatically sets these parameters accordingly along with a predetermined optimum value for the cost threshold. Unchecking it will revert the parameters to their previous values before the check box state was saved. Note: All Spanning Tree configurations and Hide SSID must be disabled manually on all Master units as this dialog box is only accessible when in Repeater mode. It is always possible to subsequently change any of these parameters if it is so desired, for example to set a different value for the Signal Strength Threshold. If this is done then the control will not display as checked as it will only display as checked if all three parameters have the preset values. Save Saves the changes and updates the radio configuration. Cancel Discards the changes without updating the radio configuration. Page 62 of 161 ProSoft Technology, Inc. November 29, 2012
RLX2 Series ♦ 802.11a, b, g, n Detailed Radio Configuration / Diagnostics Industrial Hotspots User Manual After a selection is saved and return to the Radio Network Settings panel, notice the selection is indicated under the Parent Link button. The Automatic Parent Selection algorithm uses a calculation to create a cost for each possible parent radio that it detects. The following graph describes how the cost is calculated when the signal strength threshold is set to -60 dBm. Once per second, the RLX2 radio evaluates the link it has to its parent to determine if this link is the best parent to use. A cost is calculated for each entry and can be seen in the column labeled "Cost" in the preceding table. The cost calculation is based not only on the strongest signal, but on several other factors to provide optimum network communication. Prioritized Parent Selection If more control is needed than the automatic algorithm allows, a priority list of parents for the RLX2 radio can be defined. ProSoft Technology, Inc.

Detailed Radio Configuration / Diagnostics RLX2 Series ♦ 802.11a, b, g, n User Manual Industrial Hotspot 6.2.2 IGMP Settings RLX2 radios support IGMP v1 and v2. The default operation of the RLX2 radios is to have IGMP functionality enabled, although the user can disable IGMP entirely. Additionally, the user can specify settings associated with IGMP filtering and snooping. Unknown multicast addresses can be sent to all ports (flood) or to none (filtered) by changing the IGMP Multicast Filtering option. The user can specify whether the radio will generate IGMP queries, and configure the query interval time. By RFC specification, only one device on a network should generate IGMP queries. As such, RLX2 radios will only send a query if another device has not sent a query within its Query Interval setting, even if Query Generation is enabled. Field Description IGMP Multicast Filtering Disabling filtering will cause the radio flood multicast packets to all ports. Default Propagation Action Determines how to handle multicast addresses that are not in the radio’s address table. IGMP Query Generation Enables or disables query generation from this radio. IGMP Query Interval Number of seconds between queries (if not pre-empted by a query from another device). Multicast State Count Number of queries generated before a device is removed from the multicast group on this radio if no response is received.

RLX2 Series ♦ 802.11a, b, g, n Detailed Radio Configuration / Diagnostics Industrial Hotspots User Manual 6.2.3 Rapid Spanning Tree Functionality The software’s built-in Rapid Spanning Tree (RSTP) functionality enables the setup of full redundancy between radios or other devices. Spanning Tree shuts off ports as necessary to prevent loops. If loops are created in an Ethernet network, packets can be circulated endlessly, consuming all the bandwidth and making the network unusable. Important: All radios in a network must have the same Spanning Tree configuration (enabled or disabled.) Radios will not link if some of them have Spanning Tree enabled while others do not. RSTP allows users to create truly redundant connections between any two points in the network. The radios detect the redundant paths and keep one connection alive for communications. If the primary connection fails for any reason, the secondary connection is quickly transitioned to a state to forward packets, allowing the network to adapt itself to handle problems without customer intervention. RSTP uses active communications between network devices to propagate changes in the network and to cause transitions to occur much more quickly. Because RSTP is an IEEE standard, RLX2 radios work in conjunction with wired Ethernet switches to form a redundant network. Spanning Tree details are described in the IEEE 802.1D series of specifications. Each RSTP device (RLX2 Radio or Ethernet switch) communicates with other RSTP devices in the network via packets called Bridge Protocol Data Units (BPDUs). BPDUs are sent out each of the devices ports. In a wired switch this would be from each of the Ethernet ports. In an RLX2 Radio, in addition to the Ethernet port, each wireless link is considered a port. These BPDUs are the communications means to allow each RSTP device in the network to make sure that the proper connections still exist. ProSoft Technology, Inc. Page 67 of 161 November 29, 2012
Detailed Radio Configuration / Diagnostics RLX2 Series ♦ 802.11a, b, g, n User Manual Industrial Hotspot In the following illustration, the RLX2 Radio has 4 RSTP "ports":  Ethernet port (1)  A port for its parent connection (2)  A port for each of its two child connections (11 and 12). BPDUs are sent out the port at a rate called the "Hello Time". The accepted standard value for this is 2 seconds. If a radio (or any other RSTP device) does not get a BPDU for 2 Hello Times, it assumes the RSTP device that had been there is no longer available. It can then open an alternate path if one is available. This process is much like the STP process. If other devices on the network are not operating in rapid spanning tree mode, the radio will revert to normal spanning tree operation on a per-port basis. RSTP provides a performance enhancement over STP operation. By comparison, the radio using the STP algorithm would revert its port to the listening state, and then to the learning state, before returning to the forwarding state. Each of these states takes at least 15 seconds, during which the STP devices are listening for BPDUs to re-negotiate the network topology. The advantage of using the RSTP functionality is that is uses active handshaking between adjacent RSTP devices to re-negotiate the network topology. This process takes one to two seconds. Each RLX2 Radio contains a switch table, which tells it how to forward Ethernet packets to get them to their proper destination. When the network topology changes, the RLX2 Radio the Ethernet switch table is flushed immediately. This allows it to pass traffic immediately over the new network topology and learn the configuration in the process. Until the learning is complete, the packets are broadcast to their destination. As each packet is seen and the switch table rebuilds, the radios return to directing packets to their destinations. Page 68 of 161 ProSoft Technology, Inc. November 29, 2012
RLX2 Series ♦ 802.11a, b, g, n Detailed Radio Configuration / Diagnostics Industrial Hotspots User Manual 6.2.4 Spanning Tree Settings Field Description Enable Spanning Tree Spanning Tree is enabled when this box is checked. Without spanning tree, redundant connections might exist if multiple radio links are created in parallel with each other. Redundant connections are blocked only if spanning tree is enabled. Additionally, spanning tree is used to flush the Ethernet switch table when the network topology changes as described in the section on Automatic Parent Selection. The default setting for Enable Spanning Tree is disabled. Note that many network switches implement spanning tree functionality themselves, which if enabled, will cause conflicts if Spanning Tree is also enables in the radio. Check the documentation and settings for the wired network equipment before enabling Spanning Tree in the radios. Ethernet Edge Port Because RSTP is an active protocol, it depends on communication between RSTP devices. If no RSTP device is connected to the radio’s Ethernet port, the handshake cannot take place. In this case RSTP reverts to STP. This means that the Ethernet port will be forced to adhere to the timer based transition protocol of STP. Therefore on network transitions and power up, communications will not be allowed over the Ethernet port for 30 to 45 seconds. This setting is an indication that no redundant connections exist out this port and communication can immediately be allowed. If for some reason a BPDU is received on this port, the RSTP protocol will negotiate properly and handle any possible redundant paths. The recommended setting for Ethernet Edge Port is "Enabled". Bridge Times Configures the timing intervals to use. Priority Determines who should be the root of the RSTP. The RSTP device with the lowest priority becomes the root. The accepted standard value for this is 32768. If wired switches exist in the network that support RSTP, they should always be allowed to be the root. Set this value to 32769 to prevent the radio from being the root over a wired switch. Use this setting when a radio is configured to be a Master. Set this value to 32770 when the radio is configured to be a Repeater. In this way, if only RLX2 radios exist in the network, the Master radio will become the root. Hello Time Rate at which BPDUs are sent out. The industry standard is 2 seconds. ProSoft Technology, Inc. Page 69 of 161 November 29, 2012
Detailed Radio Configuration / Diagnostics RLX2 Series ♦ 802.11a, b, g, n User Manual Industrial Hotspot Field Description Max Age Measures the age of the received protocol information recorded for a port and ensures this information is discarded when its age limit exceeds the value to the maximum age parameter recorded by the switch. The timeout value for this timer is the maximum age parameter of the switches. Forward Delay Monitors the time spent by a port in the learning and listening states. The timeout value is the forward delay parameter of the switches. Path Costs RSTP and STP algorithms use a cost to determine which connections should be used. The "spanning tree" is formed by determining the least cost paths from any RSTP device back to the root. Wireless Gives preference to a wired connection, set the Wireless cost to 200. Ethernet Gives preference to a wired Ethernet connection, set the Ethernet cost to 100. Multiple master radios can be defined on the same network. If one master radio goes down, any radios linked to it can switch over to the other master, so the networked radios remain connected and transmitting. In order to be redundant, the two masters should typically be on the same segment—in other words, they should be wired together into the same switch. These two masters can be assigned different channels to increase network bandwidth, but they must be assigned the same SSID. Also, because all radios are repeaters, each radio can be configured to reach a master radio via multiple repeater paths. If a repeater goes down, the linked radios can use a different path to get back to a master radio. Page 70 of 161 ProSoft Technology, Inc. November 29, 2012
RLX2 Series ♦ 802.11a, b, g, n Detailed Radio Configuration / Diagnostics Industrial Hotspots User Manual 6.2.5 Advanced Settings It is important to allow many industrial protocols to communicate properly over the RLX2 radios. The standard 802.11 AP operation for transmitting broadcast messages is to accumulate them and transmit them only on specific time intervals. This allows clients that are in power-save mode to wake up at the synchronized time interval and receive the broadcast packets. However, the power-save mode is rarely used in industrial networks. Additionally, many industrial protocols utilize multicast traffic, which is sent as broadcast messages over the wireless network. By enabling immediate broadcasting, these multicast messages are not delayed by the wait for the next time interval to occur before they can be transmitted. This results in improved network performance. The settings on this form also allow the configuration of the transmission rate and broadcast mode to optimize this radio's use on an industrial network.

RLX2 Series ♦ 802.11a, b, g, n Detailed Radio Configuration / Diagnostics Industrial Hotspots User Manual Field Description Max Data Rate The maximum data rate for the RLX2-IHNF radio is specified in terms of a Modulation and Coding Scheme (MCS) index value. This specification is unique to IEEE 802.11n devices. The actual maximum data rate depends on several factors as shown in the following table: 802.11n mode, MBits/sec 802.11n wide mode, MBits/sec MCS Index Active Antennas 800 ns GI 400 ns GI 800 ns GI 400 ns GI 0 1 6.50 7.20 13.50 15.00 1 1 13.00 14.40 27.00 30.00 2 1 19.50 21.70 40.50 45.00 3 1 26.00 28.90 54.00 60.00 4 1 39.00 43.30 81.00 90.00 5 1 52.00 57.80 108.00 120.00 6 1 58.50 65.00 121.50 135.00 7 1 65.00 72.20 135.00 150.00 8 2 or 3 13.00 14.40 27.00 30.00 9 2 or 3 26.00 28.90 54.00 60.00 10 2 or 3 39.00 43.30 81.00 90.00 11 2 or 3 52.00 57.80 108.00 120.00 12 2 or 3 78.00 86.70 162.00 180.00 13 2 or 3 104.00 115.60 216.00 240.00 14 2 or 3 117.00 130.00 243.00 270.00 15 2 or 3 130.00 144.40 270.00 300.00 Only MCS rates from 0 through 7 are available with one antenna, which is the default configuration. To select MCS rates of 8 and above, configure the Active Antennas to be A,C or A,B,C. (See Active Antennas below.) The maximum throughput also depends on the 802.11n Mode as configured in the Radio Network Settings section of the main webpage. See section 6.2. Throughput in 802.11n wide mode is approximately twice that of 802.11n mode. The radio will automatically select the Guard Interval (GI) based on ProSoft Technology, Inc.

Detailed Radio Configuration / Diagnostics RLX2 Series ♦ 802.11a, b, g, n User Manual Industrial Hotspot Field Description current operating conditions. The system attempts to use a 400 microsecond Guard Interval, but will fall back to an 800 microsecond Guard Interval if excessive data corruption is detected. The radio will periodically attempt to resume using a 400 microsecond Guard Interval as conditions improve. A 400 microsecond Guard Interval results in about 11% more throughput than using a 800 microsecond guard interval. The user has no control of the Guard Interval. As seen in the table above, absolutely best throughput requires 802.11n wide mode, more than one antenna, and a RF environment capable of supporting a 400 microsecond Guard Interval. Max Basic Rate In addition to the Data Rate setting which controls generic data traffic, the Basic Rate setting adjusts the rate at which control packets such as Beacons and ACKs are sent at as well as packets that need to go to the whole network such as Broadcasts. Because these packets are intended for the whole network, the Max Basic Rate setting of the Master is advertised to each of the radios in the network through Beacons. Each radio, other than the Master, then inherits the Max Basic Rate setting of the Master. Therefore the setting only needs to be made in the Master radio. The setting in each of the other radios is disregarded. Immediate Broadcasting Forward multicast traffic immediately, rather than waiting for specific time intervals. Block General Probe Requests Do not respond to general probe requests that are not specific to the radio's SSID. Range Allows the radios to account for round trip delays. The Range settings should be the same in all radios in the network and should be at least large enough to account for the length of any links. However, increasing the Range beyond what is necessary can cause a slight decrease in throughput. The default Long range is 25km, which is valid for all operating modes of all radios. TX Power Attenuation Allows reduction of the radio’s output power.. The range of attenuation is from 0 to 18 dB. Radios are shipped from ProSoft configured for maximum output power. This is either the maximum output power of the radio itself, or the maximum power allowed by country for which the radio is configured. However, it is possible to attach an antenna with so much gain that the maximum legal allowed radiated power is exceeded. This control allows the reduction of power when using such antennas so that output power is still within legal limits. See section 8.4 for information on output power regulations by the FCC for the USA. Note that higher gain antennas provide better performance in both receive and transmit functions, while output power only increases transmit performance. Page 74 of 161 ProSoft Technology, Inc. November 29, 2012
RLX2 Series ♦ 802.11a, b, g, n Detailed Radio Configuration / Diagnostics Industrial Hotspots User Manual Field Description Active Antennas This control is only available on the RLX2-IHNF radios. The default is set to A Only. The other options are A, C (for two antennas) and A, B, C for three antennas. Note that if two antennas are used, they must be attached to the ANT A and ANT C antenna connectors. MIMO antennas generally will have three connections so all three antenna ports must be activated. In general, operation with three antenna ports will give best performance. When more than one antenna port is active, the radio will monitor the signal appearing at all antenna ports and dynamically select the port(s) with the best signal. However, there are situations where performance may improve if fewer antenna ports are active. If radios are very close together (typically a few feet), all three antenna ports will receive essentially identical signal strengths and the radio may continuously change antenna ports, resulting in degraded performance. SD Auto Write Enable Enables the unit to write a copy of its Configuration to the SD Card whenever new settings are saved from any pages of the unit's web interface. Previous Configuration files are renamed with a unique file name which allows auditing of changes made to the unit's settings. SD Auto Clone Enable Enables the unit's Clone function. On power up if an SD Card is present that has a Configuration file different from the unit's current Configuration the unit will adopt the settings from the SD Card. If the Configuration matches or there is no Configuration file on the SD Card then no action is taken. On inserting an SD Card into a running unit, if the Configuration file found on the SD Card will result in the unit's settings being changed on Powerup or Reset, a warning is indicated by flashing the Signal Strength, MOD and NET LEDs. In order to save this control as enabled, either an SD Card must not be present, or the SD Auto Write Enable control must also be checked when saving. If these conditions are not present the control will be disabled before saving, to prevent the unit from reverting back to a Configuration file on the SD Card after reset. To adopt the Configuration file on an SD Card when this control is already enabled, simply insert the SD Card and power cycle the unit. If this control is not enabled, first enable and save the setting without the SD Card inserted and then insert the SD Card and power cycle the unit. NOTE: Do not enable Auto Write if you do not want the active Configuration file on the SD Card to be replaced when the unit adopts and saves the SD Card's current Configuration file. Write SD Card Immediately writes a copy of the unit's Configuration file to the SD Card, independent of the Auto Write check box setting. Note that the configuration files are in a binary format so sensitive data (e.g. passwords, encryption keys) cannot be easily read from the files.

It contains the latest updates to the 802.11 standards for best security. However, some legacy devices do not yet support these updates. Therefore, a few combinations of legacy methods can be selected. Available encryption types are:  None (not recommended)  WPA-AES - Latest security setting using WPA (pre-shared key) authentication and AES encryption.  WPA-TKIP - Security setting using WPA (pre-shared key) authentication and TKIP encryption.  WEP128 - Legacy security setting using a 128-bit key and WEP encryption.  WEP64 - Legacy security setting using a 64-bit key and WEP encryption.

RLX2 Series ♦ 802.11a, b, g, n Detailed Radio Configuration / Diagnostics Industrial Hotspots User Manual 6.3.1 Encryption type The preferred encryption type is WPA (WiFi Protected Access). Select WEP (wired equivalency protocol) for use with an older client radio that only has WEP encryption. For compatibility with clients that do not support WPA, select WPA+WEP128 (bits) or WPA+WEP64 (bits) as the encryption type. The older clients can connect to an access point using the WEP setting, but new clients will use WPA and the RLX2 radios will still use WPA among themselves. IMPORTANT: If WPA+WEP is selected, some clients using WPA might not be able to connect unless a WEP key other than number 1 is used, due to limitations in these clients. In such cases, set a WEP key other than key 1 and set this same key in all clients that are using WEP. See WEP key (page 80). WEP is the original security protocol used by 802.11 networks, but WPA offers better protection against attacks, for several reasons: WPA distances the encryption key from the actual data by performing several algorithms to the key before generating the encrypted data, it performs dynamic key management by changing keys frequently, and it performs message integrity checks to prevent forgery and replay. Selecting WEP 128, WEP 64, or None (no encryption) as the encryption type is possible, but none of these settings are recommended. Note: If an RLX2 radio is set to use WPA+WEP, it will connect to other radios set to WPA only or WPA+WEP, but it will not communicate with radios set to WEP only. Likewise, an RLX2 radio in client mode with WPA+WEP selected will not connect to an access point with WEP only selected. 6.3.2 WPA phrase To use WPA encryption on packets sent between the radios, enter a WPA pass phrase of between eight and 63 normal keyboard characters. This phrase automatically generates an encryption key of 128 hexadecimal characters. This field is only available if WPA encryption type is selected. The default WPA-AES Phrase is 'passphrase'.

Detailed Radio Configuration / Diagnostics RLX2 Series ♦ 802.11a, b, g, n User Manual Industrial Hotspot 6.3.3 WEP key A key is a set of hexadecimal (hex) or ASCII characters used to encrypt data. This field is only available when using WEP encryption type. Be sure to record the WEP encryption key to retrieve if needed. To create a 64-bit WEP key, enter five normal text characters in the WEP key field, which converts the characters automatically to 10 hex digits. Alternatively, enter 10 hex digits (0 to 9, a to f, A to F) directly in the WEP key field. To create a 128-bit key, enter 13 normal text characters, which convert to 26 hex digits, or enter 26 hex digits (0 to 9, a to f, A to F) directly. Note: Clients often support more than one WEP key. Packets received can be decrypted using any one of the keys if programmed, but packets are always transmitted with the "default" WEP key number. If a transmit key number is set on the RLX2 radio, make sure all other radios and clients have this key programmed. To set keys other than key 1 on some clients using Windows, Advanced settings may be used. Programming more than one key on the RLX2 radio requires setting the key number to the key, entering the key, and saving the changes. Repeat these steps for each key to program, saving after each one. Finally, change to the desired transmit key number if necessary and save again (If "****" remains in the key field, the previously programmed key will not be changed when changes are applied) Page 80 of 161 ProSoft Technology, Inc.

In order to configure or diagnose a radio using its built-in Web server or SNMP agent, both the computer and the radio must have IP addresses. These IP addresses must be on the same subnetwork. An IP address is only needed to configure the radio and view its diagnostic settings. Otherwise, the address is unnecessary. Field Description Obtain IP address - DHCP Allows the radio to obtain its IP address from a DHCP server. Use the following IP address Specifies a Static IP address to the radio. Enter the IP address information in the following fields. IP Address Use an IP address that will not interfere with any other devices on the network. Request a block of IP addresses to use from the Network Administrator. Subnet Mask Subnet Mask provided by the Network Administrator. Default Gateway Default Gateway address provided by the Network Administrator. Primary DNS Primary DNS address provided by the Network Administrator. Secondary DNS Secondary DNS address provided by the Network Administrator. SNMP button Opens the SNMP (Simple Network Management Protocol) Agent settings form. Use this form to configure access to radio network settings through an SNMP agent. Login Password button Configures the Login Password for the radio. The default password is "password". Change this password and keep a record of it in a safe place, to protect the radio from being reconfigured by unauthorized users. DHCP (Dynamic Host Control Protocol) is a service provided by a server (typically a router or a firewall) on a local area network. Devices on a network that supports DHCP can request and receive an IP address from the DHCP server. RLX2 radios support DHCP; by default, they attempt to obtain an IP address from a DHCP server. If a DHCP server is not available, the radio will not be able to acquire an IP address automatically. Therefore, assign an IP address, subnet mask and default gateway to the radio so that it can communicate on the network. Page 82 of 161 ProSoft Technology, Inc. November 29, 2012

This means that if the radio detects the presence of radar on its operating frequency, it must automatically change to another frequency. 6.8.1 Master Radio Operations If radar is detected on an operating channel, transmissions must cease within the required Channel Closing Transmission Time, and must move to a new channel within the required Channel Move Time. Before transmitting on a new DFS channel that has not been previously checked for radar, the Master radio must monitor the channel for the Channel Availability Check Time before transmitting. Operations cannot return to a channel where radar was detected for at least the Non-Occupancy Period. The values for these parameters are noted in the table below: Parameter FCC Value ETSI Value ETSI Value 5.600 – 5.650 GHz (Channels 120, 124, & 128) Channel Availability Check Time 60 seconds 60 seconds 10 minutes Channel Move Time 10 seconds (12 seconds for “long pulse” radar 10 seconds 10 seconds Channel Closing Transmission Time 200 milliseconds (plus up to 60 milliseconds over 10 seconds) 1 second 1 second Non-Occupancy Period 30 minutes 30 minutes 30 minutes ProSoft Technology, Inc.

Detailed Radio Configuration / Diagnostics RLX2 Series ♦ 802.11a, b, g, n User Manual Industrial Hotspot If a Master radio detects radar, it issues a channel change announcement to all Clients and Repeaters in the network. Then it moves to a new channel within the Channel Move Time. (Typically, this move time is 500 milliseconds or less.) If the selected channel was not previously checked for the presence of radar, the Master radio must do so for the Channel Availability Check Time before it can begin to transmit. If the newly-selected channel is not a DFS channel, or if the channel was previously monitored for radar since the radio was powered on, transmissions can begin immediately. During the Channel Availability Check Time, a radio blinks all three amber Signal Strength LEDS approximately once per second. If radar is detected on the new channel during the Channel Availability Check Time, the Master randomly selects another channel and begins the process again. If a Repeater in a network detects radar, it will notify the Master to change channels. 6.8.2 DFS Auto Select One of the Master channel selection options is DFS Auto Select. With this selection the radio randomly selects a DFS channel for operation. The actual channel in operation is always shown in the Current Channel display: Page 86 of 161 ProSoft Technology, Inc.

Use it in place of Ethernet cables to save money, extend range, and make connections that may not otherwise be feasible. The radio operates as a wireless Ethernet switch. Any data that can be sent over a wired network can also be sent over the radio. The RLX2 radio series is certified for unlicensed operation in the United States, Canada and Europe at 2.4 and 5 GHz. With approved high-gain antennas, the radios can achieve distances of over 5 miles line-of-sight between them. Multiple repeaters can be used to extend this range to far greater distances. A highly reliable wireless network can be developed by creating redundant (page 69) wireless paths. Multiple master (page 58) radios can be installed without any special programming or control. Repeater (page 58) radios can connect to any master at any time; if one master goes down, the repeater connects to another. Likewise, if a repeater goes down, any repeater that was connected to it can reconnect to a different repeater, keeping the network intact. Create large, self-healing tree-like networks can be done in this fashion. Fully redundant paths are possible because the Spanning Tree (page 69) protocol in the radios disables and enables paths as necessary to avoid Ethernet loops, which would otherwise halt communications. In addition to acting as a switch, every master or repeater radio in an RLX2 wireless network can simultaneously act as an 802.11 a, b or g access point. This allows 802.11 WiFi clients to connect and roam between radios for monitoring of the wireless network or general network access. The RLX2 has a special client mode (page 37) that allows connection of any Ethernet device to any existing 802.11 a, b or g access point, regardless of the brand (An example of an 802.11 client is a laptop with a WLAN card). Note: Wi-Fi is a trademark of the Wi-Fi Alliance, used to describe the underlying technology of wireless local area networks (WLAN) based on the IEEE 802.11 specifications. ProSoft Technology, Inc. Page 115 of 161 November 29, 2012
Reference RLX2 Series ♦ 802.11a, b, g, n User Manual Industrial Hotspot A high level of security is inherent with AES (Advanced Encryption Standard) encryption. TKIP (Temporal Key Integrity Protocol) is also available. If necessary, adding WEP128 or WEP64 (Wired Equivalent Protocol) encryption in addition to AES or TKIP for clients that do not support AES can be done. A simple Media Access Control (MAC) filter table restricts the radios or clients that can link to a selected radio according to the MAC IDs entered in the table. The radio is designed for industrial applications with a metal enclosure, DIN-rail mounting, and shock and vibration tested to IEC 60068. The RLX2 radio series is easy to use. Use the Radio Configuration / Diagnostic Utility, which runs in a web browser, to configure the radio. Also, an SNMP manager can be used for configuration. The radio comes with a Windows-based utility called IH Browser. It finds all the radios on the network and lists information about them. A topology view in the IH Browser shows how the wireless network is linked together at any point in time. Firmware updates can be done at anytime from anywhere on the network. This includes over the wireless link or over the Internet. ProSoft Technology radios can easily be installed into new or existing systems. The software and manuals can be downloaded from the DVD or ProSoft Technology’s web site at www.prosoft-technology.com. Page 116 of 161 ProSoft Technology, Inc. November 29, 2012
RLX2 Series ♦ 802.11a, b, g, n Reference Industrial Hotspots User Manual 8.2 Compatibility with ProSoft RLXIB Series Radios The RLX2 series radios are 100% functionally compatible with ProSoft’s legacy RLXIB-IHA, RLXIB-IHG, and RLXIB-IHW radio models. This allows customers with RLXIB series radios to add RLX2 radios to their existing networks without any reconfiguration of existing assets or obsolescence issues. The main differences in the RLX2 series radios are the following improvements: 1 Different enclosure size for more efficient heat dissipation. 2 Faster, more efficient electronics that consume less power. 3 Gigabit Ethernet. 4 MicroSD memory cards for configuration data storage. 5 Internal temperature sensor. The RLX2 series radios will acquire additional functionality as new firmware features are added. These new features will not be ported to the RLXIB radios, but the RLX2 radios will continue to work with RLXIB radios using their existing functionality. The RLX2-IHNF is an 802.11n device that does not have an RLXIB series equivalent. It cannot function as a repeater to ProSoft’s RLXIB-IHxN series radio products. Specific differences by product are noted in the following table. Specifications that have not changed between the RLXIB and RLX2 series products are not listed.

A detachable power connector comes with the radio, as shown below. The connector terminals are labeled + (positive DC connection) and - (DC ground connection). The AC-to-DC power supply adapter supplied with the optional RLX-IHBTK Bench Test Kit can be used. The DC power wires must be less than 3 meters in length to meet regulatory requirements. Important: When wiring the power connector supplied with the radio, be sure to observe the proper polarity markings on the power connector. Wiring the connector incorrectly can cause serious damage to the radio which will not be covered under the ProSoft warranty. The Power Connector (ProSoft part number 002-0116) is shown on the left in the photo above. Note the + and – polarity markings. The wire installation tool (ProSoft part number 357-0061) shown on the right is helpful for installing wires into the spring-loaded contacts inside power connector. ProSoft Technology, Inc.

RLX2 Series ♦ 802.11a, b, g, n Reference Industrial Hotspots User Manual The equipment shall be installed by a qualified installer/electrician. The installer/electrician is responsible for obtaining a secured ground connection between the lug terminal on the surge protector to a verified common ground point using a minimum 6 AWG gauge wire. This must be done when attaching power lines to the radio during installation. A solid ground connection should be verified using a meter prior to applying power to the radio. Failing to secure a proper ground could result in serious injury or death as a result of a lightning strike. Using Power over Ethernet (PoE) to power remote devices has several advantages including:  "Carrier Class" Power Over Ethernet System.  Power can be supplied over long distances, up to 300 feet.  Power can be available wherever network access is available.  The power supply can be centrally located where it can be attached to an uninterruptible power supply.  The user has the ability to easily power on reset the attached equipment from a remote location.  There is no need to run additional power cabling to the device as power can be supplied over the CAT5, CAT5E, or CAT6 Ethernet cable.  Used for remote mounted radios to save on cost of coax and reduce RF losses.  Built-in Ethernet Surge protection to prevent equipment damage.  Overload and Short Circuit protection. 8.5.2 Ethernet Cable Specifications The recommended cable is Category 5 or better. A Category 5 cable has four twisted pairs of wires, which are color-coded and cannot be swapped. The module uses only two of the four pairs when running at 10 MBit or 100 MBit speeds. All eight wires are used when running at 1000 MBit speeds. Category 5e or better cable is recommended for 1000 MBit speeds. The Ethernet port on the module is Auto-Sensing. Use either a standard Ethernet straight-through cable or a crossover cable when connecting the module to an Ethernet hub, a 10/100/1000 Base-T Ethernet switch, or directly to a PC. The module will detect the cable type and use the appropriate pins to send and receive Ethernet signals. Ethernet cabling is like U.S. telephone cables, except that it has eight conductors. Some hubs have one input that can accept either a straight-through or crossover cable, depending on a switch position. In this case, ensure the switch position and cable type agree. Refer to Ethernet cable configuration (page 126) for a diagram of how to configure Ethernet cable. ProSoft Technology, Inc. Page 125 of 161 November 29, 2012

RLX2 Series ♦ 802.11a, b, g, n Antenna Configuration Industrial Hotspots User Manual 9 Antenna Configuration In This Chapter  Antennas ............................................................................................. 135 9.1 Antennas Connecting antennas to the radio, see Connecting antennas (page 39). Consider important electrical characteristics when selecting antennas:  Antenna pattern (page 135)  Antenna gain (page 136)  Antenna polarity (page 136)  Antenna location, spacing, and mounting (page 141) 9.1.1 Antenna Pattern Information between two wireless devices is transferred via electromagnetic energy radiated by one antenna and received by another. The radiated power of most antennas is not uniform in all directions and has varying intensities. The radiated power in various directions is called the pattern of the antenna. Each antenna should be mounted so that its direction of strongest radiation intensity points toward the other antenna or antennas with which it will exchange signals. Complete antenna patterns are three-dimensional, although often only a two-dimensional slice of the pattern is shown when all the antennas of interest are located in roughly the same horizontal plane, along the ground rather than above or below one another. A slice taken in a horizontal plane through the center (or looking down on the pattern) is called the azimuth pattern. A view from the side reveals a vertical plane slice called the elevation pattern. An antenna pattern with equal or nearly equal intensity in all directions is omnidirectional. In two dimensions, an omnidirectional pattern appears as a circle (in three dimensions, an omnidirectional antenna pattern would be a sphere, but no antenna has true omnidirectional pattern in three dimensions). An antenna is considered omnidirectional if one of its two dimensional patterns, either azimuth or elevation pattern, is omnidirectional. Beamwidth is an angular measurement of how strongly the power is concentrated in a particular direction. Beamwidth is a three dimensional quantity but can be broken into two-dimensional slices just like the antenna pattern. The beamwidth of an omnidirectional pattern is 360 degrees because the power is equal in all directions. ProSoft Technology, Inc. Page 135 of 161 November 29, 2012
Antenna Configuration RLX2 Series ♦ 802.11a, b, g, n User Manual Industrial Hotspot 9.1.2 Antenna Gain Antenna gain is a measure of how strongly an antenna radiates in its direction of maximum radiation intensity compared to how strong the radiation would be if the same power were applied to an antenna that radiated all of its power equally in all directions. Using the antenna pattern, the gain is the distance to the furthest point on the pattern from the origin. For an omnidirectional pattern, the gain is 1, or equivalently 0 dB. The higher the antenna gain is, the narrower the beamwidth, and vice versa. The amount of power received by the receiving antenna is proportional to the transmitter power multiplied by the transmit antenna gain, multiplied by the receiving antenna gain. Therefore, the antenna gains and transmitting power can be traded off. For example, doubling one antenna gain has the same effect as doubling the transmitting power. Doubling both antenna gains has the same effect as quadrupling the transmitting power. 9.1.3 Antenna Polarity Antenna polarization refers to the direction in which the electromagnetic field lines point as energy radiates away from the antenna. In general, the polarization is elliptical. The simplest and most common form of this elliptical polarization is a straight line, or linear polarization. Of the transmitted power that reaches the receiving antenna, only the portion that has the same polarization as the receiving antenna polarization is actually received. For example, if the transmitting antenna polarization is pointed in the vertical direction (vertical polarization, for short), and the receiving antenna also has vertical polarization, the maximum amount of power possible will be received. On the other hand, if the transmit antenna has vertical polarization and the receiving antenna has horizontal polarization, no power should be received. If the two antennas have linear polarizations oriented at 45° to each other, half of the possible maximum power will be received. 9.1.4 Whip antennas Use a 1/2 wave straight whip or 1/2 wave articulating whip (2 dBi) antenna with RLX2 radios. These antennas are the most common type in use today. Such antennas are approximately 5 inches long, and are likely to be connected to a client radio (connected directly to the radio enclosure). These antennas do not require a ground plane. Articulating antennas and non-articulating antennas work in the same way. An articulating antenna bends at the connection.

RLX2 Series ♦ 802.11a, b, g, n Antenna Configuration Industrial Hotspots User Manual 9.1.5 Collinear array antennas A collinear array antenna is typically composed of several linear antennas stacked on top of each other. The more stacked elements it has, the longer it is, and the more gain it has. It is fed in on one end. The antenna pattern is torroidal. Its azimuthal beamwidth is 360° (omnidirectional). Its vertical beamwidth depends on the number of elements/length, where more elements equal narrower beamwidth. The antenna gain also depends on the number of elements/length, where more elements produce higher gain. Typical gain is 5 to 10 dBi. The antenna polarity is linear, or parallel to the length of the antenna. 9.1.6 Yagi Array Antenna A yagi antenna is composed of an array of linear elements, each parallel to one another and attached perpendicular to and along the length of a metal boom. The feed is attached to only one of the elements. Elements on one side of the fed element are longer and act as reflectors; elements on the other side are shorter and act as directors. This causes the antenna to radiate in a beam out of the end with the shorter elements. The pattern depends on the overall geometry, including the number of elements, element spacing, element length, and so on. Sometimes the antenna is enclosed in a protective tube hiding the actual antenna geometry. The antenna pattern (page 135) is a beam pointed along the boom toward the end with the shorter elements. The beamwidth varies with antenna geometry but generally is proportional to the length (where longer length produces a narrower beam). The antenna gain (page 136) varies with antenna geometry but generally is proportional to the length (where longer length produces higher gain). Typical values are 6 to 15dBi.

Refer to the Antenna Types overview section for other types of approved antennas (page 139). 9.1.7 Parabolic reflector antennas A parabolic reflector antenna consists of a parabolic shaped dish and a feed antenna located in front of the dish. Power is radiated from the feed antenna toward the reflector. Due to the parabolic shape, the reflector concentrates the radiation into a narrow pattern, resulting in a high- gain beam. The antenna pattern is a beam pointed away from the concave side of the dish. Beamwidth and antenna gain vary with the size of the reflector and the antenna construction. Typical gain values are 15 to 30 dBi. The antenna polarity depends on the feed antenna polarization. Page 138 of 161 ProSoft Technology, Inc. November 29, 2012

RLX2 Series ♦ 802.11a, b, g, n Antenna Configuration Industrial Hotspots User Manual 9.1.9 Antenna location, spacing, and mounting Consider the following points regarding antenna location, spacing, and mounting:  When placing antennas, ensure a clear line of sight between the master radio's antenna and all of the other radio antennas.  If the site base contains obstructing terrain or structures, mount the antenna on a tower or rooftop to provide a line-of-sight path. The line-of-sight consideration becomes more important as the transmission path becomes longer.  Mount the antennas as high off the ground as is practical. The higher an antenna is above the ground, the greater its range.  Mount the antennas away from massive structures. Radio signals bounce off metal walls, for example, which can compromise a clear signal.  Mount antennas to minimize the amount of nearby metal structures in the antenna pattern.  Mount the antennas and install radios away from sources of RF interference.  Use the shortest possible antenna cable length. Signals lose power over the cable's distance.  Choose antennas that are appropriate for the network's intended function.  If antennas are on radios on the same network, mount them so they have the same polarity. If the antennas are on separate networks, mount them so they have a different antenna polarity—for example, mount one antenna vertically and the other horizontally.  Space radios at least three feet (one meter) apart so they do not overload each other. If antennas must be near each other: o Mount omnidirectional antennas directly above each other. o Position directional antennas so they do not point at nearby antennas. Place antennas side by side if they point in the same direction. Place antennas back to back if they point in opposite directions. ProSoft Technology, Inc. Page 141 of 161 November 29, 2012

Support, Service & Warranty RLX2 Series ♦ 802.11a, b, g, n User Manual Industrial Hotspot Default Gateway The IP address of a network router where data is sent if the destination IP address is outside the local subnet. The gateway is the device that routes the traffic from the local area network to other networks such as the Internet. Device-to-Device Network (Peer-to-Peer Network) Two or more devices that connect using wireless network devices without the use of a centralized wireless access point. Also known as a peer-to-peer network. DFS DFS stands for Dynamic Frequency Selection, a requirement for operation on certain frequencies in the 5 GHz band in many countries. When a radio operates on a DFS frequency, it must sense the presence of radar and automatically change to another channel if radar is detected. DHCP The dynamic host configuration protocol is an Internet protocol, similar to BootP, for automating the configuration of computers that use TCP/IP. DHCP can be used to automatically assign IP addresses, to deliver IP stack configuration parameters, such as the subnet mask and default router, and to provide other configuration information, such as the addresses for printer, time, and news servers.

H Half-Duplex A communications circuit or system designed to transmit and receive data, but not both simultaneously. CB or walkie-talkie radios are an example of a half-duplex communication system. Either parties on a radio conversation may talk or listen; but both cannot talk at the same time without corrupting each other's signal. If one operator is "talking", the other must be "listening" to have successful communication. Hz Hertz. The international unit for measuring frequency equivalent to the older unit of cycles per second. One megahertz (MHz) is one million hertz. One gigahertz (GHz) is one billion hertz. The standard US electrical power frequency is 60 Hz. 802.11a devices operate in the 5 GHz band; 802.11b and g devices operate in the 2.4 GHz band.

Support, Service & Warranty RLX2 Series ♦ 802.11a, b, g, n User Manual Industrial Hotspot MIC Message Integrity Check. One of the elements added to the TKIP standard. A "signature" is added by each radio on each packet it transmits. The signature is based on the data in the packet, a 64-bit value (key) and the MAC address of the sender. The MIC allows the receiving radio to verify (check) that the data is not forged. MIMO Multiple Input Multiple Output refers to using multiple antennas in a Wi-Fi device to improve performance and throughput. MIMO technology takes advantage of a characteristic called multipath, which occurs when a radio transmission starts out at Point A and the reflects off or passes through surfaces or objects before arriving, via multiple paths, at Point B. MIMO technology uses multiple antennas to collect and organize signals arriving via these paths. Modbus The Modbus protocol provides the internal standard that the MODICON® controllers use for parsing messages. During communications on a Modbus network, the protocol determines how each controller will know its device address, recognize a message addressed to it, determine the kind of action to be taken, and extract any data or other information contained in the message. If a reply is required, the controller will construct the reply message and send it using Modbus protocol. Modem Stands for MODulator-DEModulator, a device that converts digital signals to analog signals and vice-versa. Analog signals can be transmitted over communications links such as telephone lines. N Network A series of stations or nodes connected by some type of communication medium. A network may consist of a single link or multiple links. Node An address or software location on the network. Non-Occupancy Period The time during which a radio cannot return to a frequency where radar was detected. This time is typically 30 minutes. Typically a radio will not return to a channel where radar was previously detected unless absolutely necessary.

Peer-to-Peer Network Each radio in a Peer-to-Peer network has the ability to receive data from - and transmit data to - any other radio in the network. Point-Multipoint (Broadcast) Network A network type where a single master radio sends data to every remote radio in the network. This is done repeatedly until every remote radio individually receives and acknowledges the data. Each remote radio sends pending data to the master radio that receives and acknowledges data sent from each remote. In this configuration, there are multiple remote radios referenced to a single master radio. Point-Multipoint (Modbus) Network A network with a single Master radio and multiple Remote radios. The devices cabled to the radios communicate through the Modbus standard protocol. The Master radio sends data to a Remote radio based on the Modbus address of the Modbus device. The data is only sent to the single Remote device based on its address. Each Remote radio sends its data only to the Master radio. The Master and Remote radios acknowledge that data was received correctly. Point-to-Multipoint A wireless network in which one point (the access point) serves multiple other points around it. Indoor wireless networks are all point-to-multipoint, and long-range wireless networks that serve multiple clients usually employ either a single omnidirectional antenna or multiple sector antennas.

Signal Strength The strength of the radio waves in a wireless network. Simplex A communications circuit or system designed to either transmit data or receive data, but not both. Broadcast television is an example of simplex communication system. A television station sends a TV signal but cannot receive responses back from the television sets to which it is transmitting. The TV sets can receive the signal from the TV station but cannot transmit back to the station. Site Survey A comprehensive facility study performed by network managers to ensure that planned service levels will be met when a new wireless LAN, or additional WLAN segments to an existing network are deployed. Site surveys are usually performed by a radio frequency engineer and used by systems integrators to identify the optimum placement of access points to ensure that planned levels of service are met. Site surveys are sometimes conducted following the deployment to ensure that the WLAN is achieving the necessary level of coverage. Site surveys can also be used to detect rogue access points. Spectrum A range of electromagnetic frequencies. Spread Spectrum A form of wireless communication in which a signal’s frequency is deliberately varied. This increases bandwidth and lessens the chances of interruption or interception of the transmitted signal. SSI Service Set Identifier is a sequence of characters unique to a specific network or network segment that’s used by the network and all attached devices to identify themselves and allow devices to connect to the correct network when one or more than one independent network is operating in nearby areas.

Assuming this is part of a Class B network (with a subnet mask of 255.255.0.0), the first two numbers (150.215) represent the Class B network address, and the second two numbers (017.009) identify a particular host on this network. T TKIP Temporal Key Integrity Protocol. The wireless security encryption mechanism in Wi-Fi Protected Access. TKIP uses a key hierarchy and key management methodology that removes the predictability that intruders relied upon to exploit the WEP key. In increases the size of the key from 40 to 128 bits and replaces WEP’s single static key with keys that are dynamically generated and distributed by an authentication server, providing some 500 trillion possible keys that can be used on a given data packet. If also includes a Message Integrity Check (MIC), designed to prevent the attacker from capturing data packets, altering them, and resending them. By greatly expanding the size of keys, the number of keys in use, and by creating an integrity checking mechanism, TKIP magnifies the complexity and difficulty involved in decoding data on a Wi-Fi network. TKIP greatly increases the strength and complexity of wireless encryption, making it far more difficult (if not impossible) for a would-be intruder to break into a Wi-Fi network. U UART Universal Asynchronous Receiver/Transmitter W WAP Wireless Application Protocol. A set of standards to enable wireless devices to access internet services, such as the World Wide Web and email. WDS Wireless Distribution System. Enables access points to communicate with one another in order to extend the range of a wireless networks. Used in 802.11g based access points. WEP Wired-Equivalent Privacy protocol was specified in the IEEE 802.11 standard to provide a WLAN with a minimal level of security and privacy comparable to a typical wired LAN, using data encryption.

RLX2 Series ♦ 802.11a, b, g, n Support, Service & Warranty Industrial Hotspots User Manual Wi-Fi A certification mark managed by a trade group called the Wi-Fi Alliance. Wi-Fi certification encompasses numerous standards including 802.11a, 802.11b, 802.11g, WPA, and more. Equipment must pass compatibility testing to receive the Wi-Fi mark. Wi-Fi CERTIFIED™ The certification standard designating IEEE 802.11-based wireless local area network (WLAN) products that have passed interoperability testing requirements developed and governed by the Wi-Fi alliance. Wi-Fi Interoperability Certificate A statement that a product has passed interoperability testing and will work with other Wi-Fi CERTIFIED products. Wi-Fi Protected Setup Wi-Fi Protected Setup™ (previously called Wi-Fi Simple Config) is an optional certification program developed by the Wi-Fi alliance designed to ease set up of security enabled Wi-Fi networks in the home and small office environment. Wi-Fi Protected Setup supports methods (pushing a button or entering a PIN into a wizard-type application) that are familiar to most consumers to configure a network and enable security. Wireless Gateway Term used to differentiate between an access point and a more-capable device that can share an internet connection, serve DHCP, and bridge between wired and wireless networks. Wireless Network Devices connected to a network using a centralized wireless access point. WLAN Wireless Local Area Network. A type of local area network in which data is sent and received via high-frequency radio waves rather than cables or wires. WPA Wi-Fi Protected Access is a data encryption specification for 802.11 wireless networks that replaces the weaker WEP. It improves on WEP by using dynamic keys, Extensible Authentication Protocol to secure network access, and an encryption method called Temporal Key Integrity Protocol (TKIP) to secure data transmissions. WPA2 An enhanced version of WPA. It is the official 802.11i standard. It uses Advanced Encryption Standard instead of TKIP. AES supports 128-bit, 192-bit, and 256-bit encryption keys.
