BEGIN Thank you and congratulations on your purchase of the ESTeem Model 195C/M Wireless Ethernet Radio Modem! This manual was written to help both the first time and advanced user of the 195C/M to configure the wireless modem for your application. If this is your first time configuring the 195C/M 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 Figure 1: ESTeem Model 195C/M Series configuration of the wireless modem for your application. The ESTeem 195C/M wireless Ethernet modems are sophisticated networking devices. 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: • • • • • • • Throughout this User’s Manual are General Ethernet networking and the configuration of LAN topologies “Technical Tips” in boxes like this that Common Ethernet terminology and acronyms have been added to help answer the TCP/IP network protocol structure and how to configure TCP/IP networks most commonly asked questions. 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, Chrome or Firefox If you are unfamiliar with any of the above networking concepts, you may need to contact your network administrator for assistance. MODEL 195C/M OVERVIEW The ESTeem Model 195C/M and 195C/M are wireless modem transceivers that can be used to build many types of Wireless Local Area Networks (WLAN). The ESTeem 195C/M series have both and Ethernet interface and an RS-232 serial port for legacy device networks. The Model 195C/M 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 refer to Chapter 4 of this User’s Manual or call Customer Support at 509-735-9092. Figure 2: Access Point Bridge Diagram Revised: 1 Oct 13 1-1 EST P/N AA107-195CM CHAPTER 1 INTRODUCTION CONFIGURATION MODES A Model 195C/M 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. Access Point Bridge Mode When a Model 195C/M is configured as an Access Point Bridge it will provide a wireless bridge for mobile clients. Multiple Access Points 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. Figure 3: Repeater Mode Diagram An ESTeem Model 195C/M 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). Repeater Mode The Repeater Mode can be used with any of the above Access Point modes. With this repeater feature enabled, the Model 195C/M 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 195C/M 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 the Model 195C/M in the Client mode to simultaneously roam under the network canopy. Self-Healing Mesh Network If multiple repeater routes are configured to the same destination ESTeem, the 195C/M 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 Revised: 1 Oct 13 1-2 EST P/N AA107-195CM CHAPTER 1 INTRODUCTION EtherStation (Client) Mode When the 195C/M is configured in the EtherStation mode and attached to a single Ethernet Device, the Model 195C/M will emulate a wireless card in functionality for communication as a mobile client. The 195C/M will seamless roam under the radio canopy of Access Points and can provide wireless communication for mobile Ethernet devices such as vehicles, forklifts, cranes, etc (Figures 2&3). RS-232 Serial Applications The ESTeem 195C/M is installed with an RS-232 data port for serial data applications run over the wireless links (Figure 6). The serial 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. Figure 6: Multi-point Serial Diagram To begin setup of your wireless Ethernet network, continue to Chapter 2 - Staring Out of this User’s Manual. Revised: 1 Oct 13 1-3 EST P/N AA107-195CM CHAPTER 2 STARTING OUT OVERVIEW There are three main phases to prepare the ESTeem 195C/M for operation in a wireless network: Phase 1 - Determine the correct mode of operation for the ESTeem in the wireless network. The ESTeem 195C/M is a sophisticated networking device that can be configured for multiple modes of operation. Determining the correct mode of operation for the ESTeem 195C/M 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 195C/M can be programmed for the wireless network. To simplify the programming of the Model 195C/M, 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 195C/M’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 195C/M can also be programmed through the internal Web interface (discussed in detail in Chapter 5) if you do not have access to the ENC Utility. Phase 3 - Install the ESTeem hardware and test communication. After the ESTeem Model 195C/M’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 195C/M HARDWARE LAYOUT To begin the configuration, unpack the ESTeem Model 195C/M shipping boxes and locate the items 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 195C/M’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 195C/M AA109 Resource Disk Antenna (AA20C.1 Displayed) Coax Cable (Antenna to ESTeem 195C/M) Power Supply (AA174 Displayed) Ethernet Cable Revised: 1 Oct 13 2-1 EST P/N AA107-195CM CHAPTER 2 STARTING OUT Note: Your accessory model numbers may vary from the above, but you will need to locate each of above items to continue configuration. Revised: 1 Oct 13 2-2 EST P/N AA107-195CM CHAPTER 2 STARTING OUT MODEL 195C/M HARDWARE CONFIGURATION The following steps should be completed to begin configuration of the ESTeem Model 195C/M: Technical Tips: 1. Connect the antenna to the TNC connection on the ESTeem Model 195C/M (Figure 1). 2. Connect the power supply and Ethernet cable to the ESTeem and proceed to Chapter 3 to begin programming. 1. Configure the Model 195C/M prior to mounting. 2. Attach antenna to the Model 195C/M before powering up. Revised: 1 Oct 13 2-3 EST P/N AA107-195CM CHAPTER 3 EXAMPLE APPLICATIONS MODES OF OPERATION The ESTeem Model 195C/M 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 195C/M is the Ethernet bridge mode. The Ethernet bridge mode will connect two or more ESTeem 195C/M’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 195C/M 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 195C/M’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 Revised: 1 Oct 13 3-1 EST P/N AA107-195CM CHAPTER 3 EXAMPLE APPLICATIONS Figure 2: Ethernet Bridge with Repeater Figure 3: Multipoint Bridge with Mesh Networking Revised: 1 Oct 13 3-2 EST P/N AA107-195CM CHAPTER 3 EXAMPLE APPLICATIONS Router Modes (AP Router and AP Masquerade) The ESTeem 195C/M 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. 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 Revised: 1 Oct 13 3-3 EST P/N AA107-195CM CHAPTER 3 EXAMPLE APPLICATIONS Mobile Client Modes (EtherStation, Station Router or Station Masquerade) The ESTeem 195C/M can also be configured to function as a mobile client. The client modes allow the 195C/M to seamlessly roam between fixed Access Points. 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 195C/M. If you are connecting the 195C/M 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 195C/M and the wireless network, while the Station Masquerade will serve as a firewall on the Ethernet side. Example Applications • Mobile applications where the 195C/M 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 • Mobile applications Figure 5: Router Mode Example Revised: 1 Oct 13 3-4 EST P/N AA107-195CM CHAPTER 3 EXAMPLE APPLICATIONS PROGRAMMING EXAMPLES Once the mode of operation for the ESTeem has been determined, you are now ready to program the Model 195C/M 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. 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. Adding ESTeems to ENC Utility and Changing Name Each of the example applications will use the following procedure to add and rename ESTeem 195C/M’s. 1.

Most Windows users will probably use either Hyper Terminal or the Terminal Emulation in the ESTeem Utility program. Programming Using the USB Port 1. When configuring the Model 195C/M for the first time you can use the ESTeem Configuration Menu to setup the basic operating parameters such as assigning the IP Address, IP Net Mask, and Gateway IP Address. 2. Connect the USB cable between the USB connector on the Model 195C/M to an open USB port on the computer. 3. Plug the Model AA174 power supply into a wall socket and connect an Ethernet patch cable from the Model 195C/M Ethernet port to the J1 (Data&PWR) port on the power supply. The Power LED on the front of the ESTeem should be illuminated. 4. If your computer is configured properly, you will see the ESTeem Model 195C/M booting sequence on your Terminal Emulation program. Once the ESTeem boot sequence is complete (approximately 45 seconds) you will receive this message: “Please press Enter to active this console.” If you don’t see this message press the Reset button on the front panel of the Model 195C/M and/or check the programming of your RS-232 port. 5. Press the Enter key and you will be at the Configuration Menu 195C/M login prompt. See Figure 1. 6. To enter the Model 195C/M Main Menu you will need to log into the system with a login name and password. 7.

Figure 3: RS-232 Welcome Screen Revised: 1 Oct 13 6-2 EST P/N AA107-195CM CHAPTER 6 SERIAL APPLICATIONS USING THE RS-232 DATA PORT The ESTeem 195C/M 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 195C/M wireless Ethernet system. The configuration for a serial 195C/M 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 195C/M 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 9-pin Sub-D serial data port is located on the face of the 195C/M (Figure 4). Using the ESTeem AA062 interface cable, the 195C/M 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. SERIAL CONFIGURATION Configuration of the serial port is completed during the standard setup of the 195C/M. After completion of the Repeater Peer configuration screen, the Serial Port Setup screen (Figure 5) will be displayed. Each section in the Serial Port Setup screen is described in detail with the following: Figure 4: 195C/M Front Panel Overview 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. Mode of Operation There are two distinct modes of operation for the serial port in the 195C/M. 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 195C/M’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 6). 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. Revised: 1 Oct 13 6-3 EST P/N AA107-195CM CHAPTER 6 SERIAL APPLICATIONS Figure 5: Serial Configuration Screen Data Bits Select the number of data bits on the RS-232 connection to match your serial device. 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. Revised: 1 Oct 13 6-4 EST P/N AA107-195CM CHAPTER 6 SERIAL APPLICATIONS 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 multipoint 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 195C/M 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.

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 195C/M 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 195C/M. 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 1 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. Figure 1: Small Mesh Network Diagram Revised: 1 Oct 13 7-1 EST P/N AA107-195CM CHAPTER 7 REPEATING FEATURES 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 2: Repeater Configuration Example You can also configure the Mesh networking directly through the web configuration setup (Chapter 5). Figure 2 shows an example repeater peer table from the setup menus. For an ESTeem 195C/M to communicate with another ESTeem 195C/M, select Yes must at Enable Repeater Capability. Next, the Wireless LAN (WLAN) MAC address of each Model 195C/M that will have direct communications must be added to the Repeater Peer List. Finally, enabling the link allows the corresponding 195C/M 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. Revised: 1 Oct 13 7-2 EST P/N AA107-195CM CHAPTER 7 REPEATING FEATURES RAPID SPANNING TREE PROTOCOL (RSTP) The ESTeem Model 195C/M 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 195C/M is used in a network that has any older STP only modems, the entire network will be STP. SPANNING TREE PROTOCOL (STP) The ESTeem Model 195C/M uses standard Ethernet Spanning Tree Protocol (STP) or Rapid Spanning Tree Protocol (RSTP) to determine the radio routing structure of the wireless network. The primary purpose of STP/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. Figure 3: Programming Example #1 Diagram 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 Revised: 1 Oct 13 7-3 EST P/N AA107-195CM
