R110 OneWireless Multinode User's Guide 3 6/08 OneWireless System Overview OneWireless is Honeywell’s network solution which connects process sensors and transmitters to the control system wirelessly in an industrial control environment. OneWireless uses Radio Frequency (RF) communications to transfer process data between the sensors and the control system, rather than the traditional wired connections. WNSIA solution There are four major components that make up Honeywell’s OneWireless network: 1. Wireless sensors (field I/O devices, such as temperature or pressure transmitters) that provide replacement for non-electronic or legacy wired sensors. 2. Wireless network infrastructure nodes (Multinodes) that serve as the network backbone to route wireless traffic towards the gateway and the control system. 3. Wireless System Gateways (WSGs) which act as bridges between the wireless network and the wired plant network. 4. Wireless device configuration tools (Wireless Builder, Key Server, Network Management and Diagnostics) allow users to configure, operate and monitor wireless devices. A typical OneWireless network using these components is shown in Figure 1.
OneWireless System Overview 4 OneWireless Multinode User's Guide R110 6/08 NOTE: The Key Server and Wireless Builder are installed on the OneWireless Server. Figure 1 Honeywell’s OneWireless solution for Wireless Network for Secure Industrial Applications (WNSIA) OneWireless Network topology Honeywell uses a wireless mesh network to achieve the OneWireless solution. A mesh network provides multiple RF communication paths between multinodes and Wireless System Gateways to transfer data to and from the wireless field devices. For example, in Figure 1 the WSG is connected to the wired network of the control system. Four multinodes are operating as Access Points (APs), communicating with the field devices and the WSG. Each multinode also is communicating with the other multinodes to form a mesh network. Multiple communications paths are also made between any field device and the WSG via any multinode in the network. Wi Fi clients can connect to the network via the multinode access points.

R110 OneWireless Multinode User's Guide 13 6/08 The Multinode/Wireless System Gateway Multinode description The Multinode is a wireless RF transmitter-receiver and router that is used to create the wireless communications network. Communication occurs by establishing radio links between the multinode and other wireless devices that are configured to operate as part of the Wireless Local Area Network (WLAN). It routes network traffic between devices, such as wireless field devices, other multinodes and wireless system gateways. The multinode is enclosed in a weatherproof enclosure and is mounted on a pole, a wall or near rooftop locations where it can transmit, receive and route control messages between field devices and the WSG. Figure 2 shows the physical features of the multinode. The multinode and the WSG are physically the same, and contain the same internal components. The operating mode selection during configuration enables the multinode to operate as a WSG or a multinode. Operating modes Multinodes can be configured to operate as either a Wireless System Gateway- in which the multinode acts as a device connecting the wireless network with the wired control system; or as a Multinode- which is an access point that communicates with the wireless field devices and the WSGs in the wireless network. Note that a WSG may also be configured to act as an access point within the wireless network. Multinodes also can be configured to provide mesh communications where multinodes communicate with other multinodes and WSGs to form a mesh network. The WSGs and multinodes use IEEE 802.11a/b/g communications protocol to communicate and complete the wireless network. Multinodes may also be connected to WSGs through a wired Ethernet link. System security OneWireless system uses both encryption keys and secure key deployment to secure the wireless network. Security of the multinodes operating in a mesh network use key encryption. During multinode configuration an encryption key is created which is then copied to the configuration of other multinodes that will operate in the same network. Every wireless communication is encrypted using a strong security key, (see Data Encryption for more information). Security between multinodes and field I/O devices is achieved through secure key deployment. Security keys are generated by the key server and then are deployed to individual field I/O devices via an authentication device. Security keys are dynamic and change automatically by the system following initial deployment providing a greater level of security for the wireless network.
The Multinode/Wireless System Gateway Physical description 14 OneWireless Multinode User's Guide R110 6/08 The Key Server is an application operating on the wireless server that stores, allocates and manages the security keys. Authentication devices are small handheld devices (PDAs) with an infrared port and buttons which are used to carry the security keys around between key server and the devices to be authenticated. The authentication device deploys the security keys to field devices to establish a trust between the device which is being authenticated (added to the network) and the key server. A couple of button presses is all that is required to authenticate a new device. See Getting Started for Honeywell OneWireless Solution for more information on authentication of wireless nodes. Additionally, the authentication device can also read and set parameters on multinodes and field I/O devices. Service Set ID (SSID) The Service Set ID (SSID) is used to define a common domain (network) among multiple wireless access points. Access points having the same SSID can communicate with each other. Two wireless networks with different SSIDs on access points can create overlapping wireless networks. The SSID can act as a password so that a client cannot connect to the network without it. However, security using the SSID is easily overridden when an access point is set to broadcast the SSID, which means that any client can associate with the AP. SSID broadcasting can be disabled in the multinode setup menus. Data Encryption You can select a data encryption option to be used for multinode wireless communications. Options include: None (no encryption), Static WEP, WPA, or AES-CCMP, depending on the multinode’s mode of operation. The AES-CCMP encryption option is available when operating multinodes in a wireless bridge network. Some level of security is recommended for all modes of operation. Wired Equivalent Privacy (WEP) Wired Equivalent Privacy (WEP) encryption is a security protocol for Wireless Local Area Networks (WLANs) defined in the IEEE 802.11 standard. WEP relies on the use of identical static keys deployed on client stations and access points. Static WEP gives you a choice of 64-bit or 128-bit encryption. A multinode configured with WEP encryption is compatible with any 802.11b PC Card configured for WEP. Wi-Fi Protected Access (WPA)/WPA2 with TKIP/ AES-CCMP WPA combines several technologies which includes the use of the 802.1X standard and the Extensible Authentication Protocol (EAP). For encryption, WPA uses the Temporal Key Integrity Protocol (TKIP) and WEP 128-bit encryption keys. Also, a message integrity check is used to prevent an attacker from capturing and altering or forging data packets. In addition, it can employ a form of AES called AES-CCMP.

Antennas The multinode is supplied with three 5dBi omni-directional antennas. Two antennas are identical and are installed to the MESH and AP connectors located on the top of the unit. These antennas are used with the 802.11 radios for client and wireless mesh communications. The third antenna is used with the field I/O radio for communication with the field devices and is installed on the FIELD I/O ANTENNA (or FHSS ANTENNA) connector. Note: The 802.11 antennas and the field I/O radio antenna are not interchangeable. A number of optional high gain antennas from various manufacturers also have been qualified for use with the multinode. Antenna selection is based on a number of factors such as frequency range, overall antenna output, and country regulations. Antenna options also include installation of the antenna remote from the multinode. When using one of these antennas, you must manually adjust the transmit power of the radios in the multinode. ATTENTION Multinodes must be professionally installed in accordance with the requirements specified in the OneWireless Multinode Agency Compliance Professional Installation Guide. If you are not using the wireless access point function then you do not need to connect the client antenna. Make sure during your configuration set up that you go to the Wireless Access Point-General screen and set the Tx Pwr Mode to Off, (See page 47). Also ensure that any unused antenna port is securely covered with the attached protection caps. NOTE: If any part of the multinode or antenna is located outdoors, a lightning arrestor must be installed between the unit and the antenna. See the Outdoor protection kit.

R110 OneWireless Multinode User's Guide 23 6/08 Installation Overview First read through this section so that you have a good understanding of the tasks to properly plan and execute installation of Multinode/WSG nodes in a wireless network. Preinstallation requirements The following tasks must be completed before you actually install wireless system gateways and multinodes in a wireless network: • Network site planning must be completed to understand how a wireless network can be built and supported for your application using OneWireless components. These components consist of wireless field devices, multinodes, and wireless system gateways. • RF site survey must be completed by a qualified professional. The RF survey is essential for building the architecture of the wireless network. The site survey should at a minimum include the following tasks: − RF spectrum analysis must be conducted on the 2.40-2.49 GHz band and 5.7-5.9 GHz band (if available to be used) to detect any potential RF interference. Strong interference sources should be addressed (removed, avoided or minimized) before an installation. Note that some frequencies may not be available for use in some locations and countries. − A point-to-point 2-node mesh should be staged in various locations to measure the RF propagation ability in the site environment. Received Signal Strength Indicator (RSSI) can serve as one indicator of the RF environment. TCP/IP throughput testing and UDP/IP throughput and packet drop rate testing should be conducted in all selected locations to measure the quality of the site environment. − Site survey should be conducted once the factory system is operating so that maximum possible interference is measured and addressed. • Multinode placement should be determined through the completion of the network planning and RF survey activities. • Power requirements for network should be identified. Wired cable runs that provide DC power to the WSGs and multinodes should be determined. • Ethernet cable runs should be determined for WSGs and/or any other wired nodes in the network.

The multinode package includes the following items: • Multinode/Wireless System Gateway • 1 Client (AP) radio antenna (if required) • 1 Mesh radio antenna • 1 Field I/O radio antenna Identify multinode site locations Site location of the wireless system gateways and multinodes are identified through the completion of the network site planning and RF survey activities. Locations can be mapped so that site preparation for the multinodes can be started.
Installation Overview Multinode/WSG installation R110 OneWireless Multinode User's Guide 27 6/08 Antenna selection Antennas play critical roles in the setup and operation of wireless mesh systems. Depending upon results of the site survey and the requirements of the installed environment, proper antenna type should be determined, (omni-directional vs. directional, low-gain vs. high gain, etc.). Assemble and install mounting hardware The multinode can be wall mounted or pole mounted using the hardware mounting kit supplied with the unit. When pole mounting the multinode you can assemble and install the mounting hardware at the site. The mounting kit includes the following items: • Mounting bracket • U-bolts with nuts • Screws (to attach the multinode to the mounting bracket) Construct conduit and cable runs for multinode power and Ethernet Power cabling from the plant must be run through conduit to a junction box installed at the multinode installation site. If the multinode will be connected to a wired Ethernet you must run Ethernet cabling from the control system through the conduit to the multinode site. Outdoor Protection Kit An outdoor protection kit must be used to prevent lightning damage when the multinode is mounted outdoors. The outdoor protection kit contains the following items: • Three lengths (10, 12 and 18-inches) of 10AWG wire with #8 ring terminal on one end and a #10 ring terminal on the other end. • Two lightning arrestors, with Type N Male-to-Female, or two Reverse Polarity Type N (RPN) Male-to-Female connectors for the mesh and AP radio antennas. • One Lightning arrestor, Type N Male-to-Female connectors for Field I/O radio antenna. Lightning arrestor installation, (when required) NOTE: A lightning arrestor must be installed between the antenna and the multinode antenna connector when the unit is installed outdoors. Use the following procedure to install lightning arrestors on the multinode.
Installation Overview Multinode/WSG installation 28 OneWireless Multinode User's Guide R110 6/08 Step Action 1 Examine the lightning arrestors and remove and discard the following items (if not needed). Securing nut, washer and ring terminal (but retain the screw). 2 Attach the 10, 12, and 18-inch wires to the appropriate lightning arrestor body ensuring that the smaller (#8) ring terminals and those wires with identifying labels are used. 3 Secure the ring terminal to the lightning arrestor using a screwdriver. 4 Install the two lightning arrestors to the multinode by attaching one end of the lightning arrestor to the multinode's MESH and AP connectors. Make sure that the lightning arrestor with the 12-inch wire is mounted closer to the ground stud and that the lightning arrestor with the 18-inch wire is mounted on the antenna connector farther from the ground stud. 5 Secure the lightning arrestors to the Type N connectors so that they are hand tight. Do not over tighten. 6 Install the Type N lightning arrestor with the 10-inch wire to the multinode by attaching one end of the lightning arrestor to the multinode's Type N FIELD I/O (or FHSS) ANTENNA connector. Hand tighten only. Note: Steps 7 and 8 may need to be performed once the multinode is mounted and connected at its site location. 7 Construct a grounding wire to be used for the earth ground connection. See Grounding in the next section for additional information. Attach the ground wire to the ring terminal attached to the multinode’s grounding stud. The earth ground ring terminal must be the first connection on the multinode's grounding stud when making additional connections to the grounding stud. 8 Place the ring terminals from the lightning arrestor ground cables on the grounding stud of the multinode enclosure and secure with a screw. Note that the earth ground ring terminal should be attached to the multinode before the lightning arrestor's ring terminal is attached. It is recommended that the outdoor protection kit be replaced every three years. If the unit is operated in an area subject to intense lightning activity, it is recommended that the outdoor protection kit be replaced every year.
Installation Overview Multinode/WSG installation R110 OneWireless Multinode User's Guide 29 6/08 Grounding NOTE: Users are responsible that the multinode connection to a proper earth ground is made by certified and authorized personnel and must conform to all applicable codes and regulations. The materials required to make a proper earth ground are defined by local regulations and must be obtained locally to ensure that the correct safety environment is achieved. The ground wire must be AWG 10 or heavier. The earth ground wire run should be kept as short as possible. Attach the earth ground wire (AWG 10 or heavier) to the ring terminal attached to the multinode's grounding stud (see Figure 3). The ring terminal must be secure against the unit's metal enclosure. The earth ground ring terminal must be the first connection on the unit's grounding stud when making additional connections to the grounding stud, (such as lightning arrestor ground wires). Sealing Antenna Connections Once all antennas have been installed, the connections should be sealed to protect them from the exterior environment. First use a wrap of electrical tape over the antenna connections. Then use a self-amalgamating polyisobutylene tape which adheres to itself and forms a single amalgamated rubber molding. Once the tape is in place for several hours, it forms a shaped rubber molding that is resistant to water and most solvents. Note that if you need to remove the tape after it has sealed for 30 minutes or more, it must be cut away. Installing the multinode/WSG at its location The assembled multinode, complete with antennas and lightning arrestors (if required), is now ready to be mounted in its site location. If the multinode is to be wall mounted, it can be secured to the wall with screws at each corner of the enclosure. When using the mounting bracket for pole installation, secure the multinode to the bracket using the screws supplied with the bracket kit. Connect power cables and Ethernet cables Conduit must be installed from the multinode ETHERNET connection to the junction box installed at the multinode site. The power cabling, green/yellow grounding wire and Ethernet cables from the multinode must be run through conduit to the junction box. Note that when installation is complete, all cabling must be routed through conduit and enclosed within the junction box. Refer to Figure 3 for multinode cable identification.
Installation Overview Multinode/WSG installation 30 OneWireless Multinode User's Guide R110 6/08 ATTENTION The power cable attached to the multinode may be one of the following: • Red cable with two wires (Red and Black) • Grey cable with two wire pairs (Red and Green, Black and White) The red (or grey) power cable, the Green/yellow grounding cable and Ethernet cables are connected as follows: Step Action 1 Ensure that all power is removed from the power cabling run to the multinode site. 2 If the multinode is equipped with a Red power cable: • Connect the Red wire from the multinode power cable to +24 volt dc output of the power supply in the junction box. • Connect the Black wire from the multinode power cable to the 24 volt COMMON of the power supply. If the multinode is equipped with a Grey power cable: • Connect both the Red and Green wires from the multinode power cable to +24 volt dc output of the power supply in the junction box. • Connect both the Black and White wires from the multinode power cable to the 24 volt COMMON of the power supply. 3 Cut and tie back the drain wire from the power cable. 4 Connect the Green/Yellow grounding cable from the multinode to a safety ground point. 5 The two WAN cables, labeled WLAN1 and WLAN2 (Ethernet cables), from the multinode are configured with the same IP address and a single MAC address and should be regarded as a two-port Ethernet switch. Therefore, if the control system provides connections to redundant switches, then use both Ethernet cables to connect to the separate switches. If only a single switch available in the control system, then use WLAN1 Ethernet cable to connect to the network switch. The two Ethernet cables should not be connected to the same network switch. Note: Using the WLAN1 cable enables the the WLAN LED indicator.
Installation Overview Multinode/WSG installation R110 OneWireless Multinode User's Guide 31 6/08 Figure 3 Multinode cable identification Power up multinodes and WSGs Once all multinodes/WSGs have been installed and connected at their site locations, turn up the multinodes to verify wireless network communications. See the Getting Started with Honeywell OneWireless Solution for more information.
Installation Overview Authenticating a multinode/WSG 32 OneWireless Multinode User's Guide R110 6/08 Authenticating a multinode/WSG Authenticating a multinode or WSG is the action taken to inject a wireless device with a security key so that when the device requests access to the system, it will be recognized and allowed to join the secure wireless network and start publishing packet information. A handheld PDA running the authentication device software is used to inject the security key into the multinode. Use the following procedure to authenticate multinodes and WSGs. Authentication order Authentication is performed once the multinode has been configured and is ready for deployment in a wireless network. Authenticate the WSG first, and then authenticate additional multinodes after you verify the gateway has been authenticated. See the Key Server event log to view authentication status of device. Prerequisite • The Key Server must be active on the network that the multinode/WSG is connecting to. • Keys from the Key Server are loaded onto the authentication device. See Getting Started with Honeywell OneWireless for the procedure. To transmit a security key to multinode/WSG: Step Action 1 If you have not already done so, power on the multinode. 2 Align the IR port of the authentication device with the IR Port of the multinode and place the authentication device 6 to 8 inches from the multinode’s IR port. 3 From the main menu of the authentication device, select Security and Node Deployment and select Clear Key and Restart Node. This clears any security keys from the multinode. The multinode LEDs will shut off for several seconds and cycle through a reboot of the multinode. 4 Select Transmit and Connect Node. A Security key deployed successfully message appears on the authentication device.
Installation Overview Authenticating a multinode/WSG R110 OneWireless Multinode User's Guide 33 6/08 Step Action 5 Verify that you receive a message on the authentication device indicating the multinode received the security key successfully. If you receive a message indicating that key deployment was not successful, repeat the procedure from step 1. 6 Select Read Device Information to determine if the multinode acquired a network address from the wireless directory server. A valid address should start with 0xEF or similar. (0x0000 indicates the multinode did not acquire a valid IP address.) TIP After the multinode has been injected with an authentication key and authenticated by the Key Server, you can look at the event log on the Key Server. • Select Start > Programs > Honeywell OneWireless > KeyServerManager, and then click Event Log.

R110 OneWireless Multinode User's Guide 35 6/08 Configuration Initial configuration Once you have received the multinode and associated hardware and physically inspected it for any damaged components, you then perform an initial setup of the unit. This should be peformed before the multinode is installed in the network at its designated physical location. The setup requires that you select configuration options, such as operating mode, security encryption and IP address, which gives the unit an identity. Also, the multinode must be given a security key to associate it with the wireless network in which it will be installed and operate (authentication). Completing setup and authentication will allow the multinode to join the network and communicate in the network. TIP When configuring multiple multinodes using the same option settings, you can create a template (configuration file) which contains the multinode settings, so that the template can be loaded to the multinodes. • First, configure a multinode using the Multinode Configuration Tool application. • Download the configuration file in the multinode to a local computer. • The configuration file then can be downloaded to additional multinodes. NOTE: The configuration file that you download to a local computer and use to configure additional multinodes contains both configuration parameters and some network parameters such as the IP address and hostname. • Update the network parameters to give the multinode a valid hostname, Description and IP Address. See System Administration for more information on downloading configuration files.

These utilities can be used to determine whether your network is unsecured. IEEE 802.11i and WPA (Recommended) Wi-Fi Protected Access (WPA) is designed to enable use of wireless legacy systems employing WEP while improving security. WPA uses improved data encryption through the Temporal Key Integrity Protocol (TKIP) which scrambles keys using a hashing algorithm and, by adding an integrity-checking feature to ensure that the keys have not been tampered with. Additionally, user authentication is enabled using the Extensible Authentication Protocol (EAP). Choosing the IEEE 802.11i and WPA Security Method will call up the following screen:

Pairwise Key If the clients use WPA-TKIP, select TKIP as encryption type. If the clients use WPA-AES, select AES-CCMP. If the clients use both encryption types, select AUTO. Pre-Authentication Enable pre-authentication to allow a client to authenticate in advance with the AP before the client is associated with it. Allowing the AP to pre-authenticate a client decreases the transition time when a client roams between APs. RADIUS Server As an alternative for business applications who have installed Radius Servers, select WPA 802.1x and input the Primary Radius Server settings. Use of Radius Server for key management and authentication requires that you have installed a separate certification system and each client must have been issued an authentication certificate. Encryption suite and Re-keying Re-keying time is the frequency in which new encryption keys are generated and distributed to the client. The more frequent re-keying (Group Encryption Key Lifetime) - the better the security. For highest security, select the shortest re-keying interval.

R110 OneWireless Multinode User's Guide 71 6/08 Wireless Mesh Configuration Introduction Wireless mesh provides a method for multinodes to communicate with each other; to extend the Basic Service Set (BSS) of a single access point (multinode), and to connect two or more separate LANs without cabling. The multinode contains a second WLAN card which is used to set up the independent wireless mesh/network connection. The multinode supports three common network types: 1. Point-to-point network of two Ethernet links 2. Point-to-multipoint network of several Ethernet links 3. Repeater mode The following sections describe the configuration options that are available to set up your network in the Multinode Configuration Tool screens. Setting up wireless networks provides typical configurations and procedures for setting up the various network types. Wireless Mesh screens The screens that you need to modify when setting up a wireless network are in the Wire-less Mesh section of the navigation bar in the Multinode Configuration Tool. These screens include: • Wireless Mesh - General • Wireless Mesh - Radio • Wireless Mesh - Encryption • Wireless Mesh - MAC Address Filtering (when Auto Mesh is selected.) General screen The Wireless Mesh - General screen shown in Figure 8 contains wireless mesh in-formation. This page is important in setting up the mesh/network configuration. Wireless mesh supports two modes of operation: Auto-forming wireless mesh (Auto Mesh) - Auto Mesh mode enables the multinode to search for beacons from other wireless meshs/networks and identifies multinodes that match configuration settings such as SSID and channel number. A three-way association handshake between the wireless networks is performed to control network access to the mesh. The maximum number links that a multinode will allow when forming the mesh
Wireless Mesh Configuration Wireless Mesh screens 72 OneWireless Multinode User's Guide R110 6/08 link is 40. It does not limit the overall size of the mesh/network or the number of networks. • Manual wireless mesh (Manual Mesh) - A manual mesh/network is defined through the wireless mesh configuration settings. Multinodes do not search for matching wireless networks, (as in the auto mesh mode). NOTE: This section describes the options that are available when using the Wireless Mesh - General screen. See Setting up wireless networks in this guide for typical multinode configurations when creating a wireless network. Figure 8 Wireless Mesh - General screen (Auto Mesh mode selected)
Wireless Mesh Configuration Wireless Mesh screens R110 OneWireless Multinode User's Guide 73 6/08 Auto mesh options When Auto Mesh mode is selected on the Wireless Mesh - General screen, the wireless mesh searches for beacons from other wireless meshs/networks and identifies multinodes that match configuration options such as SSID and channel number. ATTENTION Several of the parameters that appear in the Wireless Mesh screens are used when tuning the mesh network (Mesh priority, Signal Strength Threshold and MAC Address Filtering). See Multinode and Mesh NetworkTuning on page 97 for additional information on adjusting these parameters. Instead of simply adding the multinodes with the same SSID/channel to the network, a three-way association handshake between the wireless networks is performed to control network access to the mesh. Table 9 Auto Mesh screen options Auto Mesh Parameter Option Description Mesh Mode Auto Mesh Auto Mesh is selected. SSID numbers and/or letters An alpha-numeric ID assigned by the network administrator. This SSID must be set on each wireless device in the network so that the devices can communicate with each other. Max Direct Links 1-40 Sets the maximum number of multinode links allowed in forming a mesh link. It does not limit the overall size of the mesh/network or the number of networks. Mesh Priority 1-65535 Sets the mesh priority of the node in the network. The number should be set to a multiple of 4096. For example, use these values: 4096, 8192, 12288, 16384, 20480, 24576, 28672, 32768, 36864, 40960, 45056, 49152, 53248, 57344, 61440 and 65535 A lower the value indicates a higher mesh priority. Note: For wired Ethernet switches, WSGs and any wired multinodes, set the mesh
Wireless Mesh Configuration Wireless Mesh screens 74 OneWireless Multinode User's Guide R110 6/08 Auto Mesh Parameter Option Description priority to a value lower than all wireless multinodes in the mesh network. The lowest value (highest mesh priority) in the network becomes the STP root. See also Tuning the mesh priority. RSSI window size 1 - 100 Sets the number of samples over which the reported RSSI value is calculated. A smaller number means that the RSSI value changes more quickly and is affected more by outliner values. A larger value means that the RSSI value is not affected by transient changes in RSSI value. This parameter serves to smooth RSSI value. RF signals fluctuate over time and in different operating environments and the rate of fluctuation can vary. The RSSI value in which multinode applications use is an average of the last window size samples. The sample rate is dependent upon the beacon interval of the associated node. His parameter also servers to stabilize the wireless network. For fixed location deployment, higher values are recommended for both window-size and beacon interval. Lower values are recommended when adjusting antennas or distributing mobile mesh devices. Signal Strength Threshold 75%, 60%, 51%, 45%, 39%, 27%, 21%, 15%, 9%, None Sets the threshold of signal strength that prevents the node from associating and joining the network. When creating a mesh link, if the signal strength is less that the threshold, the link is not be created. Although once a link is created, it will not be broken even if the signal goes below the threshold. This parameter helps to stabilize the network. Link Sensitivity 75%, 60%, 51%, 45%, 39%, 27%, 21%, 15%, 9%, None The amount of change in the RSSI value required before the multinode changes its mesh link. Set this value high for good mesh stability. It is recommended that all nodes in a network are set to the same value. Once a link is created, signal strength is mapped to rapid spanning tree priority (RSTP) path cost. Since RF signals fluctuate, path cost needs to be adjusted accordingly. However, adjusting path cost too frequently causes network instablility. Path cost is adjusted if the signal strength increases/decreases by link sensitivity value since the last adjustment. If the value is set to none, evey link acts like 100% signal and no path cost adjustment is made.
Wireless Mesh Configuration Wireless Mesh screens R110 OneWireless Multinode User's Guide 75 6/08 Auto Mesh Parameter Option Description Broadcast SSID Disable/Enable When enabled, the SSID of the network is broadcast so that any client using the SSID can associate with the multinode. When disabled, the multinode hides the SSID in outgoing beacon frames to prevent stations from obtaining the SSID through passive scanning. Also, the bridge doesn’t send probe responses to probe requests with unspecified SSIDs when disabled. Signal Strength MAC The MAC address of a multinode. The signal strength of the link between this multinode and the other multinode (indicated in the Signal Strength MAC field) will be represented by the WLANSS LED located on the front of the multinode. The WLANSS LED will blink at a rate proportional to the signal strength of the link. Note that the MAC address may or may not be the addresss of the bridge link used in the mesh network. Normally, this parameter is not configured and is used only as a diagnostic aid. Manual mesh options When Manual Mesh mode is selected on the Wireless Mesh - General screen, you can manually select MAC address of a node that represents the signal strength LED and enable or disable spanning tree protocol. You can also add and delete remote AP's (multinode’s) MAC addresses. Table 10 Manual Mesh screen options Manual Mesh Parameter Option Description Mesh Mode Manual Mesh Manual Mesh is selected. Signal Strength LED MAC Not Assigned Selects the number of one of the remote multinodes that will be listed at the bottom of the screen once the system is operational
Wireless Mesh Configuration Wireless Mesh screens 76 OneWireless Multinode User's Guide R110 6/08 Manual Mesh Parameter Option Description (Remote AP’s MAC address). This wireless mesh link becomes the guiding port indicated as a signal in the WLANSS LED on the front of the multinode. 'Not Assigned' is the default. No signal indication of any multinode will be indicated when option is set to 'Not Assigned.' Spanning Tree Protocol (STP) 802.1d Enable/Disable Sets the Spanning Tree Protocol for this node. Enable STP if there is any possiblity that a mesh loop could occur. If there is no possibility that a mesh loop will occur, then disable STP. Bridge communications is faster when STP is disabled. Mesh loop Mesh loop is a condition that occurs where data is transmitted circularly between multinodes in a mesh network. For example, three multinodes are operating in a mesh network. Device data from a field device is received by one multinode which is then passed to the second multinode and then the third multinode, because all three multinodes are meshed together. It is possible that the device data could be passed on to the first multinode again creating a loop. Enabling Spanning Tree Protocol will prevent mesh loops from occurring. Monitor Linked Nodes button The Monitor Linked Nodes button in the upper right-hand corner of the Wireless Mesh - General screen allows you to view a pop-up window (Wireless Mesh Information). It shows the signal strength of all nodes linked to this multinode. Select Enable refesh, you can set the mesh refresh interval from 5 seconds to 30 minutes. Refreshing the screen allows you to see the effect when aiming the antenna to improve signal strength. The signal can be trended for each node. Monitor All Nodes button The Monitor All Nodes button in the upper right-hand corner of the Wireless Mesh - General screen allows you to view a pop-up window (Wireless Mesh Information). It shows the signal strength of all nodes detected by this multinode. Select Enable refesh, you can set the mesh refresh interval from 5 seconds to 30 minutes. Refreshing the screen

Once the key is applied, the key is no longer displayed in plain text. 7 Once you have selected the options you will use, click Apply. TIP Configure other multinodes in the mesh network following the instructions given for Multinode 1 above. Be sure that you have completed configuration of the multinode by visiting the System Configuration, Wireless Access Point and System Services screens and choosing the configuration options applicable to the wireless network. You must set the Encryption type and encryption key (if required) to ensure that the mesh is working correctly. The encryption key that you use on this screen must be the same for any mesh node connected to this network in order for communication to occur. The encryption type and key value for Mesh node 1 must be the same as for Mesh node 2 and any other mesh node in the network.
Wireless Mesh Configuration Setting up wireless networks 90 OneWireless Multinode User's Guide R110 6/08 Point-to-Multipoint network A point-to-multipoint network allows three or more multinode access points to communicate wirelessly between 3 or more locations. Figure 12 shows an example of this network type. Multinode 1 is the single access point for communication with the other mesh nodes (Mesh nodes 2, 3, …n) in the network. For the mesh nodes to be linked and communicating properly, they must be configured with compatible options in their Wireless Mesh setup screens. For example, all mesh nodes must be set with the same channel number. When setting up this type of network, Mesh node 1 must contain the BSSIDs for all other mesh nodes in the network, while Mesh nodes 2, 3, …n need to contain only Mesh node 1's BSSID. Table 15 and Table 16 list the option settings for creating the point-to-multipoint network as shown in Figure 12. Use the settings in these tables if you want to set up this type of network. The procedure to set up a wireless mesh begins on page 86. NOTE: To set up bridging for Mesh network communications, use the settings for Auto Mesh in Table 15.

R110 OneWireless Multinode User's Guide 97 6/08 Multinode and Mesh Network Tuning This section contains information on making adjustments to multinode parameters when conducting a site survey of an installed wireless network. Although a site survey was conducted during the planning phase to determine the optimal location of multinodes and WSGs to create a wireless network, once the multinodes have been installed in their designated locations a site survey should be conducted to measure the performance of the wireless network and make adjustments or tune the mesh network for the best possible and reliable wireless communication. The Network Management and Diagnostics tool also can provide realtime feedback on network performance. See the OneWireless System Administration Guide for a description of the NMD tool. Monitoring signal strength The multinode configuration tool application contains a tool that can be used to monitor the received signal strength of all wireless devices it can detect. The tool should be used during the site-survey and during multinode deployment for optimal antenna positioning. To access the monitoring tool: Step Action 1 Open Internet Explorer and access the multinode’s configuration tool by typing the URL for the multinode in the address line: https:// <ip address> Where: ip address is the IP address of the multinode. 2 From the sign-in screen, type your username and password and then click Sign In. 3 From the left pane of the Multinode Configuration Tool, click Monitoring/Reports > Adjacent AP List. 4 Refresh the page to get the most recent RSSI readings.
Multinode and Mesh Network Tuning Mesh tuning for optimal settings 98 OneWireless Multinode User's Guide R110 6/08 Note: In the Adjacent AP List screen, the Signal column lists the signal strength of the received signal (RSSI) from other access Points detected by the multinode. Signal = RSSI value. RSSI value = dbm - 95 (Subtract 95 from the RSSI value for the dbm value) For example: An RSSI of 15 equals -80 dbm. An RSSI of 20 equals -75 dbm. Mesh tuning for optimal settings Due to the variety of installation environments, the default configuration/parameter settings of the mesh network may not be the optimal settings for your site. The following are important parameters contained on the Wireless Mesh screen that you can adjust to customize the mesh for optimal performance: • Mesh link Signal Strength Threshold • Mesh priority • MAC address filtering See Table 9 for more information on these parameters.
Multinode and Mesh Network Tuning Tuning the mesh link Signal Strength threshold R110 OneWireless Multinode User's Guide 99 6/08 Tuning the mesh link Signal Strength threshold The Signal Strength threshold value is checked when a node tries to establishes a link with another node. Both nodes will check the RSSI of its partner against its configured threshold value. If the RSSI value is lower than the threshold value in either side, the link between them will not be established. If the signal strength threshold is too small, the node will establish links with all nodes it can see even though some link quality may be poor. Too many links in the mesh network can result in unnecessary and frequent changes of the network topology. If the signal strength threshold is too large, the node may not link with any other nodes and be isolated. This is an undesirable condition. The proper signal strength threshold should include 2-4 links on each node. Tuning the mesh priority Mesh priority sets the 802.1D/ RSTP (Rapid Spanning Tree) mesh priority. The latest revision of 802.1D requires the priority to be set to a multiple of 4096. Therefore, the mesh priority value should be one of the following: 4096 8192 12288 16384 20480 24576 28672 32768 36864 40960 45056 49152 53248 57344 61440
Multinode and Mesh Network Tuning Tuning MAC address filtering 100 OneWireless Multinode User's Guide R110 6/08 Further considerations should be made in setting mesh priority in a network and is dependent upon the role the multinode (or device) plays in the network. For example, if the mesh network includes a WSG which is then wired to a switch, the following priority should be assigned to the nodes in the network: Node type in network Priority Typical value Ethernet switch that uses RSTP Highest 4096 Default gateway, WSG 2nd highest 8192 Any wired multinode directly connecting to the mesh through a wired Ethernet link 3rd highest 12288 Wireless multinodes 4th highest 16384 The device with the lowest bridge priority becomes the ROOT node. This device can be any RSTP compliant device (such as a switch) and not necessarily a multinode. The mesh priority number does not affect the general topology of the mesh networks. Tuning MAC address filtering Wireless Mesh - MAC Address Filtering screen can be used to further customize the mesh network (only available in auto-mesh mode) In some cases, you may want to specifically link to one or a few nodes. You can use MAC Address Filtering to achieve this. For example, if one multinode (A) is used to stream video to another multinode (B) which is not the ROOT node, you can specify A to always connect to B and maybe another node for link backup. This allows video to be delivered using the shortest path to B. You can also use MAC Address Filtering to specify that a set of nodes NOT to connect to. For more information on using MAC Address filtering, see Wireless Mesh - MAC Address Filtering screen on page 81. Estimating network performance The values from the two tables below, (Throughput based on signal strength and Throughput based on "hops") are based on a best-case scenario. That is, there is little to no 5.8GHz RF interference sources present while the data was being passed. The values are also based on the mesh radio only. It does not take into account the stability of the link for the Field I/O radio to the sensors nor the wireless client link to the AP radio of the multinode.

R110 OneWireless Multinode User's Guide 113 6/08 Troubleshooting Overview If a fault or a failure is indicated or suspected in a wireless system gateway or multinode in the network, there are a number of tools that you can use to gather information to help diagnose a problem. • Network Management Diagnostic (NMD) tool - This tool provides a live graphic display of the mesh network showing multinodes and wireless field devices, the operating status of the nodes, and the signal strength of the links between nodes. The NMD tool allows you to access, view and change multinode configuration options (although not all configuration options can be changed using the NMD). • Data Collection - This is a method in which you can capture data logs from the wireless network and Key Server activity and save the log files. These files are then forwarded to Honeywell technical assistance for analysis. • System and Web Access logs - These logs are available using the Multinode Configuration Tool in the multinode. The logs can exported and saved to a PC for later analysis. See System and Web Access Logs for more information. • Monitoring/Report screens - A number of status screens are available in the Multinode Confguration Tool. Multinode operating status and statistics can be viewed and collected for analysis. See Monitoring/Reports screens for more information. Since the multinode contains no user-serviceable parts inside the multinode enclosure, any failure within a multinode will require a hardware replacement. Multinode failure indications Failure indication may be signaled via the multinode status LEDs. The WLAN1 and WLAN2 LEDs blink simultaneously when the system is halted. This indicates the software has detected a problem with the encryption algorithm or the system configuration does not pass the integrity check. Reboot multinode You may want to reboot the multinode if a failure is suspected. The System Administration - Reboot screen allows you to reboot the multinode without changing any configuration settings. Both CryptoOfficer and Administrator users have access to this function.
Troubleshooting Network Management Diagnostics tool 114 OneWireless Multinode User's Guide R110 6/08 If you are using the Network Management and Diagnostics (NMD) tool there is an icon on the interface that allows you to reboot the multinode. When making changes to the configuration settings of a multinode, you must reboot the multinode to enable the changes. Restore factory default settings The System Administration - Factory Default screen is used to reset the multinode to its factory settings. You must be logged in as the CryptoOfficer to access the Restore button. ATTENTION The "Restore" button is a fallback troubleshooting function that should only be used to reset the multinode to its factory default settings. Network Management Diagnostics tool The Network Management and Diagonostics tool can be use to gather event data and operation and configuration information for troubleshooting and diagnosing a problem. If troubleshooting a problem with a multinode, WSG, or field device, you must connect a PC or laptop (with the NMD tool installed) to the network in which the node is operating. Using the NMD, you can open the tool and view the nodes operating in the network and obtain node configuration settings. See the OneWireless System Administration Guide for a description of the NMD tool. Data Collection Event data can be captured and saved in files so this data can be forwarded to Honeywell Technical Assistance for analysis. Event data is sometimes cryptic and is best analyzed by trained Honeywell personnel. These event log files are collected from three sources: • The WNSIA event log is collected from the server or PC. • The Key Server Manager (KSM) event log is collected from the Key Server • The Wirelesss Capture File (WCF) is collected from the multinode. Event and file capture data is time stamped by the system which allows a view of the events leading up to and immediately after the fault event. So it is important to supply the time of the fault or failure when submitting the data files to Honeywell. Also, the WNSIA event log and portions of the WCF are constructed as circular lists, meaning that as new data is captured in the file, older data is deleted. Therefore, you should collect
Troubleshooting Data Collection R110 OneWireless Multinode User's Guide 115 6/08 these files as soon as possible after the problem occurs in order to capture the events leading up to it. Use the following procedures to capture these log files when a fault occurs. To capture the WNSIA event log Step Action 1 On the Server desktop, go to My Computer. Right click and select Manage from the menu. 2 Expand the listing under System Toolsand Event Viewer as shown in the figure. 3 Select WNSIA.
