CHAPTER 1 INTRODUCTION Revised: 22 Aug 11 1-1 EST P/N AA107A BEFORE YOU BEGIN Thank you and congratulations on your purchase of the ESTeem Model 195Ea Wireless Ethernet Radio Modem! This manual was written to help both the first time and advanced user of the 195Ea configure the radio modem for your application. If this is your first time configuring the 195Ea and you would like to get going as soon as possible, we recommend using the ESTeem Resource CD provided with the modem. The Resource CD will provide the software utilities and guide you through the configuration of the wireless modem for your application. The ESTeem 195Ea is a very versatile wireless Ethernet networking device. To keep the manual usably short, many of the application descriptions and programming details assume the user has a good working knowledge of the following network concepts:  General Ethernet networking and the configuration of LAN topologies  Common Ethernet terminology and acronyms  TCP/IP network protocol structure and how to configure TCP/IP networks and subnets  How to identify and set the TCP/IP address on your computer  Have administrator privileges to the computer and network you are configuring  If using routing protocols, you must be able to identify and configure the network routers, gateways and firewalls  You must be familiar with using web browser software such as Internet Explorer, Netscape or Mozilla If you are unfamiliar with any of the above networking concepts, you may need to contact your network administrator for assistance. MODEL 195Ea OVERVIEW The ESTeem Model 195Ea is a wireless LAN transceiver that can be used to build a Wireless Local Area Network (WLAN) for line-of-sight distances to 15 miles for fixed base and 5 miles for mobile applications. The 195Ea can provide RF data rates up to 54 Mbps and can have a serial port for legacy RS-232 devices. The Model 195Ea is a very sophisticated networking device that can be configured for multiple modes of operation depending upon the needs of the wireless and wired LAN system. The following configuration modes are provided as an overview of the basic network types, as all possible network configurations can not be listed. For further help in selecting the correct network type, please contact Customer Support at 509-735-9092. Figure 1: ESTeem Model 195Ea Throughout this User’s Manual are “Technical Tips” in boxes like this that have been added to help answer the most commonly asked questions. Figure 2: Access Point Bridge Diagram
CHAPTER 1 INTRODUCTION Revised: 22 Aug 11 1-2 EST P/N AA107A MODEL 195Ea CONFIGURATION MODES The Model 195Ea can be configured for multiple modes of operation without any changes to the hardware. The following are brief descriptions of the configuration modes. For detailed descriptions and suggested applications for each mode, please refer to Chapter 4 – Example Applications: Access Point Modes When the Model 195Ea is configured as an Access Point it will provide a wireless bridge from a hardwired Local Area Network (LAN) to other Model 195Ea modems in client modes. Multiple Access Point Bridge modems can be physically connected to the same network (LAN) or through a radio link using the Access Point Repeater mode to provide overlapping, seamless Ethernet communication for mobile devices. The ESTeem Model 195Ea in Access Point Bridge mode will pass all network traffic between connected devices including global network broadcasts. 1. Access Point Bridge Mode The ESTeem Model 195Ea in Access Point Bridge mode will both provide wireless access to mobile clients (Access Point) and bridge all Ethernet data connected to the Ethernet ports. The AP Bridge mode will pass all network traffic between connected devices including global network broadcasts. See Figure 2. 2. Access Point Router Mode In this mode the ESTeem Model 195Ea will function as a router between wired Ethernet networks, connected to the 195Ea’s Ethernet port, and the wireless network of mobile clients and other 195Ea’s. As in all standard router configurations, the wireless and wired Ethernet networks will need to be on separate subnets. The 195Ea in Access Point Router mode will pass network traffic for connected devices but will block global network broadcasts from the wired network. This mode of operation should be used instead of the Access Point Bridge mode when a separation between networks is required or the ESTeem is connected to larger LAN Networks that will continuously send global network broadcasts (Figure 3). Figure 3: Repeater Mode Diagram Figure 4: Access Point Masquerade Diagram
CHAPTER 1 INTRODUCTION Revised: 22 Aug 11 1-3 EST P/N AA107A 3. Access Point Masquerade Mode The Access Point Masquerade mode is a special use of the Access Point mode where the Model 195Ea will connect multiple clients into a single static IP address on a wired network. Data requests from the wireless network will be processed through the Access Point Masquerade 195Ea, but any request from the wired Ethernet network to devices on the wireless network will be rejected similar to the operation of a “firewall”. The 195Ea will hide all the IP addresses connected on the wireless link. You should use this mode of operation if Model 195Ea is connected directly to the Internet with a static IP address (DSL, T1, etc.) and you want the wireless clients to access the information through the Model 195Ea (Figure 3). This mode should also be used for attaching the Model 195Ea to a network where few IP addresses are available or a firewall for the wireless clients is required. 4. Access Point Repeater The Access Point Repeater can be used with any of the above Access Point modes. With this repeater feature enabled, the Model 195Ea Access Points do not have to be hardwired together on the same physical LAN to provide seamless Ethernet communication for roaming clients. In addition to greatly extending the Access Point canopy range, the Model 195Ea will also bridge any Ethernet device or Ethernet network connected to the unit over this same wireless Ethernet network. This mode gives the user the features of a point to multi-point bridge network but also allows Model 195Ea in the Client mode to simultaneously roam under the network canopy. 5. Self-Healing Mesh Network If multiple Access Point Repeater routes are configured to the same destination ESTeem, the 195Ea will create a “self-healing” mesh network by automatically re-routing data through alternate paths to reach its destination if the primary path is inoperable. The routing and priority of alternate paths is completely user configurable. See Figure 5. Figure 5: Mesh Network Diagram
CHAPTER 1 INTRODUCTION Revised: 22 Aug 11 1-4 EST P/N AA107A Station (Client) Modes 1. EtherStation Mode. When the 195Ea is configured in the EtherStation Mode and attached to a single Ethernet Device, the Model 195Ea will provide wireless mobile access to that device through a canopy of Access Points. The 195Ea will seamless roam under the radio canopy of Access Point and can provide greatly increased range for mobile Ethernet devices such as vehicles, forklifts, cranes, etc (Figures 1-3). 2. Station Router Mode. The Station Router mode will also function as a client, similar to EtherStation, but will allow multiple Ethernet devices to be connected to a single 195Ea (Figure 3). The 195Ea will function as a router between the wireless client mode and the wired Ethernet devices connected to the Ethernet port. Similar in configuration to the Access Point Router mode, the wireless and wired Ethernet networks will need to be on separate subnets. To communicate from wireless network to devices on the wired Station Router network, a separate router (connected to the Ethernet side of the Access Point) is required. This mode would be used where multiple Ethernet devices will be connected to a single Model 195Ea in a mobile client application and the connected Ethernet devices will need to be accessible from the Access Point’s LAN network. 3. Station Masquerade Mode. The Station Masquerade Mode is another mode where multiple devices will be connected to a single ESTeem in a mobile or Client application, but unlike the Station Router mode, the Station Masquerade will consolidate all connected Ethernet devices to a single IP address on the network. The devices connected to the Station Masquerade 195Ea will be able to access information from both the wireless and wired LAN, but will be inaccessible the other way similar in application to a firewall. This mode would be used where multiple Ethernet devices will be connected to a single Model 195Ea in a mobile application and the IP addresses for each device will be hidden from the LAN connected to the Access Point. See Figure 3. Serial Applications. The ESTeem 195Ea is installed with an RS-232 data port for serial data applications run over the broadband link (Figure 5). The serial over broadband network can be used in a point-to-point or point-to-multi-point application for networking serial (RS-232c) devices, providing serial connections to legacy hardware in a new Ethernet network or providing for high-bandwidth devices (such as Video or Voice over IP) in an existing serial network. Installing the serial port option also provides a second 10/100 Base-T Ethernet port that can be used to connect a second Ethernet device without requiring a HUB/Switch or can be configured as an external Router port. To begin setup of your wireless Ethernet network, continue to Chapter 2 - Staring Out of this User’s Manual. Figure 6: Multi-point Serial Diagram
CHAPTER 2 STARTING OUT Revised: 23 Aug 11 2-1 EST P/N AA107A OVERVIEW There are three main phases to prepare the ESTeem 195Ea for operation in a wireless network: Phase 1 - Determine the correct mode of operation for the ESTeem in the wireless network. The ESTeem 195Ea is a sophisticated networking device that can be configured for multiple modes of operation. Determining the correct mode of operation for the ESTeem 195Ea is the first step. Chapter 3 of this User’s Manual details the modes of operation and applications where each would be used. Phase 2 - Program the ESTeem for operation in the wireless network. Once the correct mode of operation for the ESTeem has been determined, the 195Ea can be programmed for the wireless network. To simplify the programming of the Model 195Ea, ESTeem has created a new software utility called the ESTeem Network Configuration (ENC) Utility which is used to graphically configure the primary and backup communication routes between ESTeem 195Ea’s in the network. The ENC Utility can be installed from the ESTeem Resource Disk or from the ESTeem web site (www.esteem.com). Chapter 4 (Utilities and Features) of this User’s Manual will guide you in the installation of the software and give a brief overview of operation of the ENC Utility, but a detailed User’s Guide is available both on the ESTeem Resource Disk and in the Help section of the program itself. The ESTeem Model 195Ea can also be programmed through the internal Web interface. If you do not have access to the ENC Utility you can program the 195Ea for operation directly in the modem as detailed in Chapter 5. 3. Install the ESTeem hardware and test communication. After the ESTeem Model 195Ea’s programming, install the hardware in each remote location. Chapter 8 of this User’s Manual describes the antenna specifications, mounting options and the configuration of the pole mounting hardware for the ESTeem. For instructions on testing and troubleshooting the wireless link, refer to Appendix F (Troubleshooting). MODEL 195Ea HARDWARE LAYOUT To begin the configuration, unpack the ESTeem Model 195Ea shipping boxes and locate the items contained below for initial configuration. Take a few minutes to inventory your equipment before you proceed. Report any missing or damaged items to Customer Support (509-735-9092) as soon as possible. Each node in your ESTeem Model 195Ea’s network may have different hardware components based upon the final installation location (i.e Outdoor, Indoor, Point-to-point or Muti-Point). Antenna types, cable lengths, power supplies may be different, but the following items will be required for basic setup: Model 195Ea AA109 Resource Disk Antenna (XXX Displayed) (2) Ethernet Cables Power Supply (AA175.2 Displayed) Serial Interface Cable (AA6021.1) Note: Your accessory model numbers may vary from the above, but you will need to locate each of above items to continue configuration.

CHAPTER 3 EXAMPLE APPLICATIONS Revised: 6 Sep 11 3-1 EST P/N AA107A MODES OF OPERATION The ESTeem Model 195Ea is a sophisticated wireless networking device that can be configured for multiple modes of operation. Determining the correct mode of operation for the ESTeem is the first step in creating a reliable wireless network. This chapter will explain each mode of operation, provide example applications and detailed programming information for each mode. Please review the following modes of operations. If you do not see an example of your application, please contact ESTeem support at 509-735-9092 for help in selecting your mode of operation. Ethernet Bridge Mode (AP Bridge) The most commonly used mode of operation with the ESTeem Model 195Ea is the Ethernet bridge mode. The Ethernet bridge mode will connect two or more ESTeem 195Ea’s while passing all network traffic that arrives in both the wireless and connected Ethernet ports; including all global network traffic (Figure 1). This mode will work in most wireless applications of the 195Ea to wirelessly connect two or more remote Ethernet devices or networks. The Ethernet bridge mode is also used in repeating (Figure 2) and in self-healing Mesh networks (Figure 3) for fixed (non mobile) applications. Example Applications  Building to building remote wireless LAN networks  Point to point wireless Ethernet communication devices  Multi-point wireless Ethernet networks  Remote Supervisory Control and Data Acquisition (SCADA) networks  Redundant, self-healing Mesh networks  Fixed locations with mobile ESTeem 195Ea’s Applications Where Ethernet Bridge Mode Not Used  Mobile applications (see Mobile Clients)  Connections to large Ethernet traffic networks such as large office buildings or plant networks (see Router modes) Figure 1: Point to Point Example
CHAPTER 3 EXAMPLE APPLICATIONS Revised: 6 Sep 11 3-2 EST P/N AA107A Figure 3: Multipoint Bridge with Mesh Networking Figure 2: Ethernet Bridge with Repeater
CHAPTER 3 EXAMPLE APPLICATIONS Revised: 6 Sep 11 3-3 EST P/N AA107A Router Modes (AP Router and AP Masquerade) The ESTeem 195Ea can be configured as a network router or network firewall between the Ethernet LAN connection and the wireless network of remote locations. The router modes are used to limit the network traffic from a busy Ethernet network connection to only those specific IP address used on the wireless network (see Figure 4). The Ethernet router mode (AP Router) will allow bi-directional communication from the Ethernet LAN connection to the wireless network. The Ethernet firewall mode (AP Masquerade) will allow Ethernet devices in the wireless network to request information from the Ethernet LAN network and receive a response, but no traffic can be generated from the Ethernet LAN side. Example Applications  Wireless Ethernet networks connected to large company or plant Ethernet LAN networks (AP Router)  Wireless Ethernet networks with a requirement for network isolation from the plant or company network (AP Router)  Shared Ethernet connection to direct Internet service (DSL, Cable, T1, etc.) (AP Masquerade) Applications Where Ethernet Router Mode Not Used  Mobile applications (see Mobile Clients)  Simple network connections only using a single IP network subnet (see Ethernet Bridge modes) Figure 4: Router Mode Example
CHAPTER 3 EXAMPLE APPLICATIONS Revised: 6 Sep 11 3-4 EST P/N AA107A Mobile Client Modes (EtherStation, Station Router or Station Masquerade) The ESTeem 195Ea can also be configured to function as a mobile client. The client modes will allow the 195Ea to seamlessly roam between other 195Ea configured as Access Points (AP). These Access Points can be ESTeem 195Ea’s configured in one of the three Access Point modes (AP Bridge, AP Router or AP Masquerade – see above). The client modes will allow mobile Ethernet devices to connect to each other or to an Ethernet LAN through the fixed AP (Figure 5). The EtherStation mode is used to connect a single Ethernet device to the ESTeem 195Ea. If you are connecting the 195Ea to multiple Ethernet devices in a mobile mode, the Station Router or Station Masquerade will be required. The Station Router will allow bi-directional communication between the Ethernet devices connected to the 195Ea and the wireless network, while the Station Masquerade will serve as a firewall on the Ethernet side. Example Applications  Mobile applications where the 195Ea will change links often between fixed Access Points  Long range mobile client networks  Public safety applications for police, fire and EMS Applications Where Mobile Client Mode Not Used  Fixed locations using Ethernet Bridging or Routing  Wireless Ethernet networks with repeaters Figure 5: Router Mode Example
CHAPTER 3 EXAMPLE APPLICATIONS Revised: 6 Sep 11 3-5 EST P/N AA107A PROGRAMMING EXAMPLES Once the mode of operation for the ESTeem has been determined, you are now ready to program the Model 195Ea for use. ESTeem has created a simplified network programming utility call the ESTeem Network Configuration (ENC) Utility. This ENC Utility will be used in all the following programming examples. For detailed instructions on installing the ENC Utility, please refer to the User’s Guide (found in the ESTeem Resource CD or Utility program itself) or Chapter 4 of this User’s Manual Adding ESTeems to ENC Utility and Changing Name Each of the example applications will use the following procedure to add and rename ESTeem 195Ea’s. 1. Consult the ENC Utility’s User Guide on how the create a new wireless network. Once you have a blank network configuration page (Figure 6), select , select ESTeem from the menu items to display the drop down menu, then select New>New ESTeem. 2. Enter in the ESTeem Model 195Ea serial numbers used for the example (for example enter E-14000 in the Set Serial Number Box) and press the OK button (Figure 7). The ENC Utility will look up the ESTeem 195Ea’s serial number in the database and match the correct Wireless LAN MAC (WLAN MAC) address to the modem. This WLAN MAC address will be displayed above the modem symbol on the screen (Figure 8). Technical Tip: The ENC Utility calculates the wireless link information based upon exact ESTeem serial numbers. The serial numbers listed in the following examples are for example only. Enter the correct ESTeem serial numbers for your application. Figure 6: Adding ESTeem to Blank ENC Configuration Page Figure 7: Enter the Serial Number

CHAPTER 3 EXAMPLE APPLICATIONS Revised: 6 Sep 11 3-13 EST P/N AA107A Mobile Client Mode Example (Figure 5) EtherStation, Station Router and Station Masquerade Modes (3) ESTeem Model 195Ea Serial Numbers: E-14000 (EtherStation) E-14001 (Station Router) E-14002 (Station Masquerade) Setting the ESTeem for Mobile Client (station) mode with the ENC Utility is different than the Bridge/Router or Access Point (AP) modes. ESTeem modems configured in as a Mobile Client will not link with a specific fixed modem; but will roam between any 802.11 Access Point with the correct Network Name (SSID) and Encryption. The ESTeem configured as a client is also not set on a specific operating frequency (channel) but will scan all channels looking for the AP. Use the following procedure to configure an ESTeem 195Ea in one of the three mobile client modes: 1. Starting a new network of ESTeem 195Eas in Mobile Client mode is the same as any of the Bridge modes except when you are asked for the frequency (channel) of operation, select “Station” (Figure 23). 2. Add the three mobile client modems to the ENC Utility configuration page as instructed above and set the Modem ID to match the three modes of operation. Your configuration will appear as in Figure 24. EtherStation 3. By default, the ENC Utility sets all station mode ESTeem modems to EtherStation mode. The only adjustment necessary to the EtherStation modem in our example is to enter the connected Ethernet device’s MAC address. The ESTeem 195Ea will “clone” the Ethernet MAC address of the connected Ethernet device. To configure the EtherStation modem, double-click on the icon to bring up the ESTeem Summary window and press the Edit button (Figure 20). 4. EtherStation mode should be selected in the Mode of Operation. Press the Next button at the bottom of the window to continue.

The 195Ea currently can not be used as a VLAN switch, but will pass VLAN tagged Ethernet packets through the wireless bridge. Figure 13: Advanced Settings Menu
CHAPTER 4 UTILITIES & FEATURES Revised: 6 Sep 11 4-10 EST P/N AA107A IGMP SNOOPING Internet Group Management Protocol (IGMP) Snooping allows the ESTeem 195Ea to operate more efficiently in networks with high Multicast (UDP, etc.) traffic. IGMP Snooping will define the destination for the Multicast traffic and send the data to the correct wireless Ethernet modem, not the entire network. This limiting of Multicast traffic to specific destinations greatly increases the overall network efficiency. The problem with using multicast traffic over a wireless connection is that multicast packets do not require an Acknowledge on the protocol layer. If the wireless network misses a data packet on the RF network, that multicast data packet is lost. Theory of Operation There are two types of Ethernet packets on a network, unicast and multicast. Unicast is intended for exactly one recipient (and ignored by all others). Multicast is intended to be received by multiple recipients. Interested parties can listen for particular multicast packets, but most nodes ignore it. In any case, the network medium is still utilized no matter how many nodes are listening. Broadcast packets are a special type of multicast traffic which all nodes always receive. These are particularly useful for global announcements (Hey, I'm Alice!) and queries (Hey, I'm Alice and I'm looking for Bob!). More relevantly, it is how hosts on a network find out each other's addresses, and are absolutely crucial to the proper functioning of a network. As the network grows physically, it encounters some growing pains. The first is more physical, relating to the cabling limitations. Bridges solve this problem by joining two physical networks together so they appear to be a single large network. Through use of bridges, a network can scale to hundreds or even thousands of hosts. There is a downside, however. Well before the physical limitations of bridging hit, you start to run into efficiency problems, as all traffic has to travel everywhere on the network. The raw carrying capacity of this shared medium, often referred to as bandwidth, is the second scaling problem. Smart bridges, or switches, help alleviate the bandwidth problem by only passing traffic across the bridge if the destination host was on the other side. This greatly increases the capacity and efficiency of the network by allowing two pairs of hosts communicating simultaneously on each side of the switched bridge. Only when the packet needs to go to the other side is both mediums utilized simultaneously for the same packet. Unfortunately, broadcast and multicast traffic by its very nature must always be relayed across the bridge. While the number of network nodes may grow linearly, the multicast traffic tends to grow exponentially. This isn't generally a problem for wired networks, as they have a considerable amount of bandwidth to spare, but wireless networks have, at best, an order of magnitude less bandwidth to begin with. If a wireless network is bridged with a wired network, while the absolute numbers are the same, a much higher proportion of the wireless network’s available bandwidth is used up by multicast traffic. This effect is further magnified if multiple wireless repeaters are in use. The preferred way of dealing with excess multicast traffic is to put the wireless network on a different sub-network (subnet) and use a router to join it to the wired network. This ensures that only unicast traffic intended for the wireless network crosses over, as multicast and broadcast traffic stays within its local subnet. Normally this is fine, but there are times where you need multicast traffic to span subnets. For IP traffic, this can be obviated by using a multicast-capable router, but for legacy multicast protocols that were not designed to be routed, another solution must be found. There are two primary types of communication networks used in wireless Ethernet systems; fixed points communicating to each other through an Ethernet Bridge and mobile devices communicating to these fixed points. The fixed point Ethernet bridge communication in the 195Ea is through Repeater Peer links, while the mobile communication is from the Client modes (EtherStation, Station Router and Station Masquerade) to the Access Points (Fixed Locations) in the network. Each of these networks handles Multicast traffic differently as explained below. Ethernet Bridge Mode (Repeater Peers)
CHAPTER 4 UTILITIES & FEATURES Revised: 6 Sep 11 4-11 EST P/N AA107A When the ESTeem 195Ea is configured as a repeater peer, all multicast traffic is “wrapped” in a Unicast frame and sent to all other repeater peers. (Figure 14) This operation allows the ESTeem network to receive an acknowledge packet and retransmit the data if the packet is lost during transmission. This unicast encapsulation will work regardless if the protocol can support IGMP or not. Figure 14: Repeater Peer Operation
CHAPTER 4 UTILITIES & FEATURES Revised: 6 Sep 11 4-12 EST P/N AA107A Ethernet Bridge Mode (Repeater Peers) With IGMP Snooping When the ESTeem 195Ea is configured as a repeater peer, IGMP Snooping is enabled and the network supports IGMP protocol, the 195Ea will begin to identify the connected Ethernet devices using Multicast transmissions and report this information to the network. As this process continues, all sites that have Multicast traffic on the wireless network will only send these requests to the specific ESTeem reporting the Ethernet device (see Figure 15). Figure 15: Repeater Peer with IGMP Enabled
CHAPTER 4 UTILITIES & FEATURES Revised: 6 Sep 11 4-13 EST P/N AA107A Client Modes When the ESTeem 195Ea is configured as a mobile client (EtherStation, Station Router or Station Masquerade), there are two configurations that will increase the reliability of Multicast traffic. The first phase is encapsulation of the multicast packets, as described in the Repeater Peer, and the second is IGMP Snooping if the network will support the protocol. The encapsulation of the Multicast packets will operate regardless of the IGMP support to increase the reliability. Figure 16: Unicast Packet to All Clients Figure 17: Unicast Packet to Single Client

CHAPTER 6 SERIAL APPLICATIONS Revised: 9 Sep 11 6-3 EST P/N AA107A USING THE RS-232 DATA PORT The ESTeem 195Ea has a serial data port that can provide RS-232 communication between two or more serial devices using the wireless broadband link. The serial data is encapsulated and transferred as a standard Ethernet packet over an operating 195Ea wireless Ethernet system. The configuration for a serial 195Ea network will be the same as an Ethernet or a serial (RS-232) based communication network. The serial interface option can be used to link two or more serial devices in a new or existing system. The serial data has very little impact on the network bandwidth and will allow for both Ethernet and serial applications simultaneously. A possible application would be installation of the 195Ea in an existing serial based network that was looking for future upgrade to an Ethernet based system. Another would be using the high-bandwidth Ethernet connections to provide a link to remote video hardware while also providing a serial link to the existing PLC in a SCADA type application. SERIAL CONNECTIONS The RJ-45 serial data port is the far-left port on the face of the 195Ea (Figure 4). Using the ESTeem AA0621 interface cable, the 195Ea can be connected to a standard DTE-device (PC) with a male 9-pin Sub-D connector. The complete cable configuration is available in Appendix C – Interface Ports. Second Ethernet Port Installation of the serial option also includes installing a second 10/100 Base-T Ethernet interface. This second Ethernet port can be used to Bridge to the first Ethernet port (ETH_0) and the wireless link working as a two-port HUB when configured in the AP Bridge mode. This second Ethernet port can also be configured as a Router port between the wireless and the first Ethernet port in AP Router mode (Figure 5). AP Bridge Mode In the AP Bridge mode, both Ethernet ports (primary and secondary) and the wireless port (WLAN_0) are configured for a common IP subnet and share the same IP address. AP Router Mode In the AP Router mode, the two Ethernet ports will be on the same IP subnet, while the wireless port will be on a separate IP subnet. If desired, the secondary Ethernet port (ETH_1) can be configured for a 3rd subnet (i.e. subnet C). This requires advanced configuration and routing tables specific to the particular networks.

CHAPTER 6 SERIAL APPLICATIONS Revised: 9 Sep 11 6-4 EST P/N AA107A Configuration of the serial port is completed during the standard setup of the 195Ea. After completion of the Repeater Peer configuration screen, the Serial Port Setup screen (Figure 6) will be displayed. Each section in the Serial Port Setup screen is described in detail with the following: Enable the RS-232 Data Port Enabling the serial data port allows the modem to send RS-232 data over the broadband wireless connection established with the ESTeem repeater peers. The modem can be configured in a point-to-point or point-to-multipoint system. Select Yes if you wish to enable the serial data port. Figure 6: Serial Configuration Screen
CHAPTER 6 SERIAL APPLICATIONS Revised: 9 Sep 11 6-5 EST P/N AA107A Mode of Operation There are two distinct modes of operation for the serial port in the 195Ea. The Redirector mode will provide two-way serial communication between two or more serial devices, while the Terminal Server mode will allow serial communication to a specific remote site by connecting through telnet or SSH. Select one of the following modes of operation: Full Redirector Mode - This mode allows bi-directional RS-232 data communication with other ESTeem Model 195Ea’s. The RS-232 data transmission will appear transparent to the connected devices as if a serial cable is connected between the two ports. This mode will also be used in a multi-point serial network were all serial devices will need bi-directional communication (Figure 7). Terminal Server Mode - This mode of operation translates RS-232 serial data into a network-oriented terminal protocol, such as telnet or SSH. This mode would be selected if an interactive RS-232 session at remote locations is desired over the wireless Ethernet link. Baud Rate Select the data rate of the RS-232 connection to match your serial device. Data Bits Select the number of data bits on the RS-232 connection to match your serial device. Figure 7: Serial Full Redirector Example
CHAPTER 6 SERIAL APPLICATIONS Revised: 9 Sep 11 6-6 EST P/N AA107A Stop Bits Select the number of stop bits on the RS-232 connection to match your serial device. Parity Select the parity of the RS-232 connection to match your serial device. Flow Control Select the type of data flow control used on the RS-232 connection. The ESTeem can support Hardware flow control (RTS/CTS control lines) or Software Flow Control (XON/XOFF). Select None if no serial flow control is necessary. Maximum Bridge Links for Multicast Packets This value sets the maximum number of Ethernet bridge links that the multicast packets will be sent through when used in a multi-point system. A multi-point serial network uses multicast packets (UDP) to send the data to more than one remote ESTeem. You want to limit the number of network bridge links that these UDP packets will be passed through to make the network more efficient. If you are using multiple ESTeem repeater links to send the serial data to remote locations, the value for the maximum bridge link needs to be increased to a number greater than the longest repeater chain. For example, if you are using four repeater (peer) links to send the serial data between two or more sites the number will need to be five (5) or greater (Figure 4). Destination IP Address The ESTeem configured for the correct destination IP and port number will send and receive the serial data from another modem. Set the destination IP address for the ESTeem where the serial data will be sent. If sending to more than one ESTeem (Multipoint) set to a multicast address (i.e 224.0.0.1). Note: If you are using the ESTeem 195Ea in a multipoint application (multicast), you must have default Gateway configured in the ESTeem set to the IP address of the Root Bridge modem. Serial IP Port Number The ESTeem configured for the correct destination IP and port number will send and receive the serial data from another modem. Set the IP port numbers to match where the serial data will be sent. The serial data will not be sent if both the IP address and port number is not correct. Maximum Packet Size This number represents the maximum size of the serial data packet in bytes. If the number of bytes of data in the serial port buffer exceeds the maximum packet size before the timer or delimiter character is reached, the ESTeem will send forward the serial packet. For example, if the maximum packet size is set to a value of 100, when the serial port receives 100 bytes the data will be sent through the wireless connection. Number of Milliseconds for Packetization This number represents the time the ESTeem will hold data in the serial data buffer before sending to the remote ESTeem. This feature is generally used if the serial data does not have a consistent packet length or delimiter character. For example, if the number of milliseconds is set to a value of 10 the ESTeem will monitor the incoming serial data stream and any break in characters longer than 10 milliseconds will cause the data will be sent through the wireless connection. Delimiter Characters Enabling and specifying a delimiter character will transmit the data in the serial buffer when the delimiter character is recognized in the serial data stream. There are two unique delimiter characters that can be configured and enabled independently. Terminal Server Control Lines Enabling this feature will allow the ESTeem in the Terminal Server mode to read and generate modem control lines to the connected device.
CHAPTER 7 REPEATING FEATURES Revised: 9 Sep 11 7-1 EST P/N AA107A To increase the wireless network’s area of coverage for both indoor and outdoor applications, the ESTeem 195Ea utilizes a custom repeating feature that allows increased coverage areas without the added expense of hard cabling or adding an additional point to point radio link. With a conventional IEEE 802.11a Access Point (AP) network, all of the APs have to be interfaced to a common network either by hardwire, see Figure 1, or a separate, dedicated RF backbone. The Model 195Ea can create this RF backbone, bridge Ethernet networks connected to the wired Ethernet port and provide the wireless canopy for 195Ea clients simultaneously. When programmed in any of the three Access Point (AP) Repeater Modes, the Model 195Ea will create a wireless network with other Model 195Ea units in radio range that are programmed in the AP Repeater Peer table during setup. This feature adds the increased functionality of repeaters to the typical Ethernet Bridge configuration. ESTEEM MESH NETWORK One of the most powerful features of the AP Repeater Mode is the ability to input multiple communication routes and designate the priority for each of these routes to create a wireless Mesh network. The ESTeem Model 195Ea will automatically change communication routes in the network if a route has failed. The new route will be based upon the priority level set during configuration. This wireless Meshing technology allows the RF network to “self-heal” if any of the communication paths fail. The routing priority is manually set during the configuration of the 195Ea. A manual path configuration is far superior to standard “self-discovery” networks, because you have direct control over the best RF paths and can easily identify any failed routes for easy troubleshooting. For example, Figure 2 shows a typical wireless Ethernet system used in the Water/Waste Water Industry. The problem with a standard “self-discovery” Mesh network is the selection of routes. Notice that the communication between the Water Plant (Site A) and Pump Site D has a marginal link, but it is the most direct route between the Ethernet devices. This scenario poses the question, which path will the network select? The ESTeem Mesh Network takes out the guessing games by allowing the user to select and prioritize all communication routes in the system. In our example we would want the primary link to go through Tank B (Repeater) and use the direct link only if this primary link fails. The following sections will show how this completed. Configuration The configuration of the repeater paths is completed during setup of the Access Point modes. All three Access Point modes support repeating and Meshing features. The Mesh network configuration using the ESTeem Network Configuration (ENC) Utility is shown in detail in Chapter 3 of this User’s Manual. Figure 1: Conventional Access Point Diagram Figure 2: Small Mesh Network Diagram
CHAPTER 7 REPEATING FEATURES Revised: 9 Sep 11 7-2 EST P/N AA107A You can also configure the Mesh networking directly through the web configuration setup (Chapter 5). Figure 3 shows an example repeater peer table from the setup menus. For an ESTeem 195Ea to communicate with another ESTeem 195Ea, Yes must be selected at the “Enable Repeater Capability.” Next, the Wireless LAN (WLAN) MAC address of each Model 195Ea that will have direct communications must be added to the Repeater Peer List. Finally, enabling the link allows the corresponding 195Ea to be included in the communication routing. Mobile clients do not require input in the repeater peer table. If multiple Mesh routes are configured, you will also need to set the values for Priority and Path Costs (explained in Spanning Tree below). For multiple examples of repeater configurations, please refer to Chapter 3 of this user’s manual. RAPID SPANNING TREE PROTOCOL (RSTP) The ESTeem Model 195Ea uses Rapid Spanning Tree Protocol (RSTP - IEEE 802.1d) to determine the radio routing structure of the wireless network. This RSTP functions the same as standard Spanning Tree Protocol (STP) listed below, but the network recovery is three times faster. If the 195Ea is used in a network that has any older STP only modems, the entire network will be STP. Figure 3: Repeater Configuration Example
CHAPTER 7 REPEATING FEATURES Revised: 9 Sep 11 7-3 EST P/N AA107A SPANNING TREE PROTOCOL The ESTeem Model 195Ea uses standard Ethernet Rapid Spanning Tree Protocol (RSTP) to determine the radio routing structure of the wireless network. The primary purpose of RSTP is to make sure that “network loops” are not created. A network loop is having two communication paths to the same destination where the remote device would receive the same data multiple times. If there were no way to control the data flow, this data would be constantly passed around this loop causing a “packet storm” that would shut down the entire network. The Spanning Tree Protocol will block all these redundant links. The STP operation begins by determining which Ethernet device on the network will be the Root Bridge. All Ethernet networks have a Root Bridge that is selected by the lowest MAC address. All path costs are evaluated against this Root Bridge device to determine routing and which paths will be blocked. On a wired Ethernet network, the location of the Root Bridge is not really important, but in a wireless network selection of the Root Bridge is critical to the wireless network routing. Let’s use one of the Example network diagrams from Chapter 5 to continue the discussion (Figure 4).

CHAPTER 7 REPEATING FEATURES Revised: 9 Sep 11 7-4 EST P/N AA107A The following sections describe the process of the STP in the ESTeem Model 195Ea as how it would happen in the above example. Learning Phase - Once properly configured, each Model 195Ea will begin to search out the other Model 195Ea units in radio range that are programmed in the AP Repeater Peer table. All Model 195Ea’s will calculate their routes to every Model 195Ea in the network based upon the lowest “path length” to the Root Bridge. Path length is the total number of wireless links (repeater peer links) to transmit a packet through the wireless network to the Root Bridge. Note: The Root Bridge in a network should be the Model 195Ea where the majority of the data flow is processed. In every wireless network of two or more radios, the Root Bridge should be user defined. If not defined, the ESTeem 195Ea with the lowest MAC address will be designated as the Root Bridge. In Figure 4, the Plant network (Example 1) is the most logical location for the Root Bridge based upon the amount of data flow. Setting this site as the root bridge is discussed below in Root Bridge. Blocking and Forwarding Phase – To ensure you do not have a network loop situation due to redundant paths in your wireless network, the Model 195Ea will recognize and disable (block) one or more redundant links and provide back up links should the primary link fail. This establishes a wireless mesh network with a series of forwarding links, based upon the shortest path length to the Root Bridge. For example, looking at Figure 4, the Remote Building has two routes to the Root Bridge (Plant Network – Example #1); directly to the site and through the repeater. The direct link between the two sites is the shortest route (lowest Path Length) and will be selected as the primary route unless overridden by manually changing the Path Length in the configuration. Path Length If more than one communication path to the Root Bridge is found, the 195Ea must determine which route to take based upon the lowest Path Length. The default path length to all links in the 195Ea network is 1. If the Path Lengths are equal then the lowest MAC address will determine the priority route. In the ESTeem Mesh Network we want to directly control all data flow so do not want the routes to be automatically determined. Looking again at our Example in Figure 4, if we made no changes to the default path length of 1 (note values in Figure 3) the lowest path cost would be direct from the Remote Building to the Root Bridge (Plant Network). Link Description Total Path Length Direct from Remote Building 1 Remote Build to Root Bridge Through Repeater 2 (Length 1 to repeater + Length 1 to Master = 2) To configure the 195Ea to select the repeater as the primary radio path, set the path length value for the direct link greater than 2 (such as a value of 3) to make this the primary radio path. The lowest path length will identify the highest priority. The Model 195Ea will use this routing, but also switch to direct communication if the repeater were to disappear. Root Bridge In any Access Point Repeater network consisting of more than two sites, one Model 195Ea should be designated as the Root Bridge. Only one Model 195Ea can be designated as the Root Bridge in a given network and should be located where the majority of the Ethernet data flow is processed. This site may be the Master location in a SCADA network or could be configured at a repeater site. Selection is important because all Model 195Ea’s NOT configured as the Root Bridge will choose routing based upon the Path Length to the Root Bridge. If you have any question as to which site in your AP Repeater application should be the Root Bridge, contact ESTeem Customer Support at 509-735-9092 or e-mail your application to support@esteem.com. The Root Bridge will be selected in one of two ways: the Root Bridge can be manually set (recommended) during the configuration of the Repeater Peer table (Figure 3) or the Root Bridge designation will default to the lowest MAC address of all the Model 195Ea’s in the network. The manual Root Bridge configuration is located in the “Advanced Settings” section.
CHAPTER 7 REPEATING FEATURES Revised: 9 Sep 11 7-5 EST P/N AA107A Redundant Backup The ESTeem Model 195Ea configured in Access Point Repeater mode will automatically function as a redundant backup if two Model 195Ea’s are installed at the same location (Figure 7). If two Model 195Ea’s are connected to the same switch, one of the Model 195Ea’s will be Blocked when the Spanning Tree Protocol is completed. The network will continue to use this route until any problem with the original Model 195Ea is detected and the second Model 195Ea will begin operation at that site. Redundant Master Configuration – The configuration in Figure 7 will also provide a redundant backup for the Master Site (Root Bridge). Configure both Model 195Ea’s as Root Bridges (see above) giving the primary Root Bridge a value of 1 and the secondary Root Bridge a value of 2. Figure 7: Redundant Backup Diagram

CHAPTER 8 ANTENNA SETUPS Revised: 27 Jan 12 8-7 EST P/N AA107A 195E POLE MOUNT GROUNDING PROCEEDURES Mounting the 195E series radio modem outdoors requires proper grounding procedures to prevent damage to both the radio hardware and the connected Ethernet and Serial peripherals. The case on the 195E series wireless modem is electrically conductive, but the AA195 Pole Mount kit provides isolation from the connected structure. To bring the 195E case to a ground potential with Earth ground and eliminate any static buildup on the case itself, the shield on the Ethernet cable is used to provide the ground connection. Outdoor Ethernet Cable A critical component of this grounding protection system is the ESTeem AA09.1 outdoor, shielded CAT-5E Ethernet cable. This cable provides three, necessary elements; Ethernet data, DC Power over Ethernet (PoE) applications, and a ground from the 195E case to the AA166 surge protector. The Ethernet cable is outdoor rated and protected from UV breakdown. Installation The following diagram outlines all the critical components and connections in the 195E series system. The Earth ground connection to the surge protector must be installed to comply with local Electrical code requirements.

APPENDIX D RADIO CONFIGURATION Revised: 6 Sep 11 APX D-1 EST P/N AA107A 195Ea FREQUENCY OF OPERATION In a wireless Ethernet network all of the ESTeem Model 195Ea’s must be set to the same radio frequency of operation or channel. Listed on the right is a table showing the channel and corresponding frequency of operation. The frequency of operation is selectable when configuring the mode of operation of the 195Ea (reference Chapter 3). See Figure 1. RF COMMUNICATIONS DATA RATE The RF data rate of the Model 195Ea can be programmed for operation at 6, 9, 11, 12, 18, 24, 36, 48, or 54 Mbps. The RF data rate can be set for a fixed rate or a specific range that is dynamically scaled by the Model 195Ea from monitoring the received signal quality. The Model 195Ea can communicate with multiple 195Ea wireless modems at different data rates for each device. Dynamic scaling means that the Model 195Ea will operate at the highest RF data rate that is programmed into unit. If the received data quality drops below the required minimums for reliable communications the Model 195Ea will reduce the data rate to the next lowest step to increase signal quality. Conversely if the signal quality increases above the minimums the Model 195Ea will increase the RF data rate the next highest level. SETTING RF POWER LEVEL The ESTeem Model 195Ea peak power is adjustable in output power from 250mW to 1 Watt. The output power is adjusted on the Advanced Menu>Wireless LAN Settings>Wlan0 Device screen (Figure 3) of the Web Configuration Manager. Select the value and press the Save Settings button.

APPENDIX E SECURITY Revised: 9 Sep 11 APX E-1 EST P/N AA107A OVERVIEW The security for the ESTeem Model 195Ea, like all network security, must be multi-layered. One level of security is never enough to make sure that data does not end up in the wrong hands. Please review the following security levels and decide what is the most appropriate for your network. AES-CCMP (802.11i and WPA-2) AES-CCMP (Advanced Encryption Standard-Counter Mode CBC-MAC Protocol) is the encryption algorithm used in the IEEE 802.11i and WPA-2 security protocols. This national encryption standard uses a 128 bit-AES block cipher and CCMP technique to ensure the highest level of security and integrity available on a wireless network. AES-CCMP incorporates two sophisticated cryptographic techniques (counter mode and CBC-MAC) and adapts them to Ethernet frames to provide a robust security protocol between the mobile client and the access point. AES itself is a very strong cipher, but counter mode makes it difficult for an eavesdropper to spot patterns, and the CBC-MAC message integrity method ensures that messages have not been tampered with. The ESTeem 195Ea is compatible as either an Access Point or client in either WPA2 or IEEE 802.11i security systems. Wi-Fi Protected Access 2 with Preshared Key (WPA2 PSK) WPA2 PSK uses a common passphrase (preshared key) between the Access Point (AP) and the client to begin a secure communication session. This passphrase must be entered exactly the same in both the Access Point and the client. This passphrase is used to authenticate communication session between the AP and client to begin the secure wireless networking session. Wi-Fi Protected Access 2 with Enterprise Server (WPA Enterprise) Like WPA2 PSK, WPA2 Enterprise verifies the authenticity of the Access Point and client, but uses an 802.1x backend authentication server handling the authentication decision. The most commonly type of authentication server is a RADIUS server. The ESTeem Model 195Ea can be configured to operate with an established RADIUS server on the network. WPA Wi-Fi Protected Access with Preshared Key (WPA PSK) WPA, which uses 802.1x, was introduced in 2003 to improve on the authentication and encryption features of WEP. All authentication is handled within this access point device. WPA has two significant advantages over WEP: 1. An encryption key differing in every packet. The TKIP (Temporal Key Integrity Protocol) mechanism shares a starting key between devices. Each device then changes their encryption key for every packet. It is extremely difficult for hackers to read messages even if they have intercepted the data. 2. Certificate Authentication (CA) can be used, blocking a hacker posing as a valid user. Wi-Fi Protected Access with Enterprise Server (WPA Enterprise) Like WPA PSK, WPA Enterprise verifies the authenticity of the Access Point and client, but uses an 802.1x backend authentication server handling the authentication decision. The most commonly type of authentication server is a RADIUS server. The ESTeem Model 195Ea can be configured to operate with an established RADIUS server on the network. WPA is server/client relationship from a software driver on a computer’s wireless LAN (WLAN) card to an Access Point. The scope of WPA is limited in use to this configuration only. The ESTeem Model 195Ea can support WPA Enterprise and PSK as an Access Point, but the level of security on the Bridging layer is configured separately.
APPENDIX E SECURITY Revised: 9 Sep 11 APX E-2 EST P/N AA107A 128-BIT WEP The 128 WEP uses a particular algorithm called RC4 encryption to encode and decode traffic that is based on a 104-bit encryption key and a 24-bit Initialization Vector (IV). RC4 starts with a relatively short encryption key (104 bits) that is expanded into a nearly infinite stream of keys to accompany the stream of packets. The basic concept of RC4 is good, but the way it’s implemented in WEP leaves it open to compromise. The researchers that test the integrity of the system usually focus on one piece of the implementation, the Initialization Vector (IV). The IV (24 bits) is the algorithm component that’s supposed to keep expanded keys from repeating. From the researcher’s point of view, a high-volume access point is mathematically guaranteed to reuse the same key stream at least once a day. When this happens, it’s called an IV collision this becomes a soft spot to enter the system. The researchers aren’t saying that it’s easy to break into the system, or that it’s being done on a regular basis, only that it is possible and that administrators should consider ways to reduce the possibility ACCESS CONTROL LIST (ACL) The ACL is one of the simplest yet most secure methods of network security. The ACL is a configurable MAC filter in the Model 192E that can be set to allow specific MAC address on the wireless network by individual address or address ranges. The same filter can also be set to reject individual MAC addresses or address ranges. The MAC address is a unique, 6 hexadecimal field address assigned at the manufacturer that can not be changed. The MAC address is traceable through the IEEE governing body to the manufacturer and is the “fingerprint” for all Ethernet devices. Using a combination of both the WPA or 128-Bit WEP encryption and the ACL filter provide the ESTeem an extremely secure wireless networking layer. DISABLING BROADCAST PROBES AND HIDING SSID A simple but very effective way of securing a network is to make the network difficult to find. By disabling broadcast probes and hiding the Service Set Identification (SSID), wireless and network “sniffers” will not be able to find your ESTeem Model 195Ea network. To gain access to the wireless network, you would be required to have the SSID and all security loaded in the WLAN card software prior to entering the network. PROPRIETARY BRIDGE COMMUNICATION Although the ESTeem Model 195Ea is compatible with the open communication standards IEEE 802.11g and 802.11b, the repeater communication between the units is a proprietary communication link. No other manufacturer of wireless hardware can access the ESTeem repeater network when bridging between Ethernet networks. This proprietary communication layer, in combination with the other security settings, allows you as the user to reject wireless clients into the network if so desired. When used in conjunction with the Access Control List the 802.11g and 802.11b client access can be removed. The security level of the bridge communication link is configurable for 64-Bit WEP, 128-Bit WEP or TKIP and is completely independent of the client access level or any other communication link level. For example, an ESTeem Model 195Ea can be configured for WPA Enterprise for client level access, communicate to another ESTeem Model 195Ea using a TKIP bridge link and also communicate 128-Bit WEP to our older ESTeem Model 192E radio modems all running simultaneously.
APPENDIX E SECURITY Revised: 9 Sep 11 APX E-3 EST P/N AA107A MASQUERADE MODES When the ESTeem Model 195Ea is configured in either the Access Point Masquerade or the Client Masquerade modes, the wireless modem will function as a network firewall. If access to the wired network is the greatest concern, place the ESTeem in the Masquerade mode and the wireless network will be completely isolated from the wired Ethernet network. INCREASING NETWORK SECURITY The following are a few suggestions to help improve the overall security of your wireless network: 1. Enable the security. If you research all of the articles regarding hackers, they have gotten into the user’s network due to the security not being enabled. 2. Set the ACL filter to include only those MAC address of the wireless Ethernet device being used on the network. 3. Make sure the keys are not reused in your company, since reuse increases the statistical likelihood that someone can figure the key out and change the default password on your access point or wireless router 4. As a network administrator, you should periodically survey your company using a tool like NetStumbler to see if any "rogue" access points pop up within your company without authorization. All of your hard work to "harden" your wireless network could be wasted if a rogue AP was plugged into your network behind the firewall. 5. Many access points allow you to control access based on the MAC address of the NIC attempting to associate with it. If the MAC address of your NIC isn't in the table of the access point, you won't associate with it. And while it's true that there are ways of spoofing a MAC address that's been sniffed out of the air, it takes an additional level of sophistication to spoof a MAC address. The downside of deploying MAC address tables is that if you have a lot of access points, maintaining the tables in each access point could be time consuming. Some higher-end, enterprise-level access points have mechanisms for updating these tables across multiple access points of the same brand. 6. Consider using an additional level of authentication, such as Remote Access Dial-in User Service (RADIUS), before you permit an association with your access points through WPA and WPA2 Enterprise. 7. If you're deploying a wireless router, think about assigning static IP addresses for your wireless NICs and turn off Dynamic Host Configuration Protocol (DHCP). If you're using a wireless router and have decided to turn off DHCP, also consider changing the IP subnet. Many wireless routers default to the 192.168.1.0 network and use 192.168.1.1 as the default router. 8. Only purchase Access Points that have flashable firmware. There are a number of security enhancements that are being developed, and you want to be sure that you can upgrade your access point. 9. A simple security technique used by the military is to have the administrator periodically change the key for the system i.e. weekly, monthly, etc.
APPENDIX F TROUBLESHOOTING Revised: 6 Sep 11 APX F-1 EST P/N AA107A TESTING COMMUNICATION LINK After you have configured at least two of the Model 195Ea wireless Ethernet modems for operation, you can verify communication with each the following steps: Status Light The quickest source of link status is to view the Status Light on the face of the 195Ea (Figure 1). If the Status light is solid, the Model 195Ea has a connection to another Model 195Ea listed in the Peer Table. Status Screen/Peer Table To view detailed information on the status of the communication link (such as connection speed, signal strength and last update time) you can open the Status Screen from the Web Interface. After press the Status tab at the top of the screen the Status: Summary will be displayed showing the status of all ports and memory in the 195Ea. Under the Wireless Status heading click on the View Peer Table (Figure 2). The Peer Table will list all other wireless activity seen by the 195Ea and how it is classified. Note: The data rate displayed is not necessarily indicative of the RF data rate between the ESTeems. The rate show in the Repeater Peer table will be the last RF packet, which could consist of either data, repeater beacon or network probes.

APPENDIX F TROUBLESHOOTING Revised: 6 Sep 11 APX F-2 EST P/N AA107A Repeater Peers - The Peer Table will display all connected 195Ea’s configured to repeat to this ESTeem by their Wireless (WLAN) MAC address. Received Signal Strength – This is the first of the two numbers listed in the block. This signal strength value is listed in dBm. Last RX – This is the time of the last received data packet. When monitoring the status menu, it is important to note the time the last transmission was updated so you are not looking at “stale” data. Current Data Rate – This is the current speed the last data packet received by the Model 195Ea. This may not be the data rate between the radio modems. Note that the speed is listed in kbps, so that 11000 kbps is equal to 11 Mbps. Note: The ESTeem Model 195Ea uses spread spectrum technology that analyzes each data packet for signal strength and data quality (strength vs. noise). The higher your signal, the mare background noise you can sustain without causing degradation in the data transfer. This is also true for lower signal strengths with a very low background noise. These values are provided for guidance and if you have any questions about the values in your application, please contact ESTeem Customer Support at 509-735-9092 or e-mail your application to support@esteem.com. Modem ID – This is Modem ID for the opposite repeater peer. Viewing RF Data Rates The value shown on the Peer Status Screen for data rate may not be the actual rate of the RF link. To view the link information, click on the Opposite Modems WLAN MAC address in the Repeater Peer list (Figure 2) and further link status information will be displayed (Figure 3). Once loaded, click on View Peer Rate Control Information. (Figure 4) Figure 3: Peer Summary Table
APPENDIX F TROUBLESHOOTING Revised: 6 Sep 11 APX F-3 EST P/N AA107A The value of the Current TX rate is the RF data rate between the two ESTeem Model 195Ea. SIGNAL STRENGTH VS DATA RATE The following chart will show the average signal strength required to maintain a data rate. Please note that the data rates listed here can be greatly effected by overall activity on the radio channel and the total background noise. This values should be used as a guide, but testing after installation is required. Receive Signal Strength RF Data Rate -89 dBm 1 Mbps -86 dBm 2 Mbps -85 dBm 5.5 Mbps -88 dBm 6 Mbps -87 dBm 9 Mbps -82 dBm 11 Mbps -84 dBm 12 Mbps -82 dBm 18 Mbps -79 dBm 24 Mbps -75 dBm 36 Mbps -70 dBm 48 Mbps -68 dBm 54 Mbps Note: The signal strength required for the above data rates are effected by other RF transmitters in the area. A higher signal strength will be required in applications with high background noise. Figure 4: Rate Control Information
APPENDIX F TROUBLESHOOTING Revised: 6 Sep 11 APX F-4 EST P/N AA107A LONG RANGE POINT TO POINT APPLICATIONS The factory configuration on the 195Ea is optimized for distances up to 10 miles. If your application has an RF link with a range greater than 10 miles, you will need to set the maximum range value on both ESTeem 195Ea’s on this communication link. To access the Maximum Distance value select Advanced from the top Menu then Wireless LAN Settings>wlan0 device and press the Next button (Figure 5). Scroll down the menu list until you find the Maximum Distance variable (Figure 6). Enter the maximum distance of the connection in miles.

APPENDIX F TROUBLESHOOTING Revised: 6 Sep 11 APX F-5 EST P/N AA107A TROUBLESHOOTING TIPS General (Applicable to All Modes of Operation) Where do I find the latest firmware version number? – We have the latest version number of the Model 195Ea firmware listed on the ESTeem Web site (www.esteem.com) under the Model 195Ea product page. How and when do I update the Model 195Ea firmware? - You should only update the Model 195Ea firmware if you are having a specific problem and it is recommended that you do so by ESTeem Customer Support personnel. All the update instructions and files are located on the ESTeem FTP site at the following address: ftp://www.esteem.com/195Ea Do all firmware versions have to be the same to communicate between the Model 195Ea? – It is not necessary for all the firmware versions to be the same revision to communication, but the later version may have added features that the other versions will not recognize. What characters are valid for WEP Key entry? - Only the Hexadecimal characters 0-9 and A-F are valid for key entry. What ESTeem Utility version is required to program the Model 195Ea? – The ESTeem Utility program is not required to program the Model 195Ea. The 195Ea can be programmed using any Terminal Emulation program (such as Windows HyperTerminal) and any web browser program. What is the speed and duplex configuration on the Model 195Ea – The Model 195Ea is an auto-negotiation full/half-duplex 10/100 Base-T interface. Ether a cross-over or patch cable is supported. Access Point Mode Wireless LAN cards are not connecting – Verify that the wireless LAN cards are set to Infrastructure Mode, have a matching SSID (or ESSIS) set the same as the Model 195Ea and that all encryption codes are the same. My Wireless LAN card shows a solid connection, but I can not pass any data – Verify the encryption and the ACL setting on the Model 195Ea match the wireless LAN card. Access Point Repeater Mode How long does it take to re-establish the Wireless Ethernet Network? - If a communication link is lost and the Wireless Network needs to re-establish the repeater routes, the time can take up to 10 seconds. Should the AP Repeater Mode be used on mobile equipment? - The AP Repeater mode should be used on equipment that will not change the Repeater Route as it moves. For example, if a mobile device such as a crane can communicate directly to another ESTeem and will not loose the link in its travel, the AP Repeater Mode could be used. If the device requires two ESTeem Model 195Ea’s (Base and Repeater) to maintain communication across its complete travel, the Station Modes should be used on the mobile device. The problem will be in the time that the mobile ESTeem will take to transfer between the two sites. In Access Point Repeater mode the transfer can take up to 30 seconds, while the EtherStation mode will transfer without a packet loss. Does WEP have to be used? – The WEP does not have to be enabled for the modems to communicate, but all modems must be configured the same way. Correct configuration, but cannot establish communications. – In addition to the network configuration, all 195Ea modems configured in the AP mode must share the same SSID and be on the same frequency channel. The most likely cause of the error is the WLAN MAC address is not configured in both 195Ea’s repeater tables. If only one side is configured, everything will appear to be correct but no communication will function.
APPENDIX F TROUBLESHOOTING Revised: 6 Sep 11 APX F-6 EST P/N AA107A EtherStation How do I access the Model 195Ea web page in EtherStation Mode? The Model 195Ea does not have an active web browser when configured in EtherStation mode. You must access the ESTeem with the ESTeem Discovery Program or through the RS-232 port after configuration in this mode. To monitor the link status, you can use the EtherStation Status program. What IP address do I configure the ESTeem in EtherStation mode? – The Model 195Ea will not have an IP address in EtherStation mode. I can not link my device into the wireless network – Verify that the MAC address of the device is exactly the same as configured in the Model 195Ea. The MAC address must have colons between the values. Can I connect my Model 195Ea in EtherStation mode to a HUB or Ethernet Switch? – No. The modem must be connected directly to the Ethernet device for which it is programmed. In EtherStation mode the Model 195Ea can only service ONE Ethernet device.
