CHAPTER 1 INTRODUCTION 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.
CHAPTER 1 INTRODUCTION MODEL 195Ea MODES CONFIGURATION 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.
CHAPTER 1 INTRODUCTION 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”.
CHAPTER 1 INTRODUCTION 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.
CHAPTER 2 STARTING OUT 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.

Assemble the 195Ea hardware as shown in Figure 4. Technical Tips: 1. Configure the Model 195Ea prior to mounting. 2. Attach antenna to the Model 195Ea before powering up. 3.
CHAPTER 3 EXAMPLE APPLICATIONS 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.
CHAPTER 3 EXAMPLE APPLICATIONS Figure 2: Ethernet Bridge with Repeater Figure 3: Multipoint Bridge with Mesh Networking Revised: 6 Sep 11 3-2 EST P/N AA107A
CHAPTER 3 EXAMPLE APPLICATIONS 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).
CHAPTER 3 EXAMPLE APPLICATIONS 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).
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 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.
CHAPTER 3 EXAMPLE APPLICATIONS Figure 8: Main Office ESTeem 195Ea 3.

CHAPTER 4 UTILITIES & FEATURES ESTeem Network Configuration Utility (ENC) The ESTeem Network Configuration (ENC) Utility is a software program designed to greatly simplify the configuration of your ESTeem Model 195E wireless Ethernet network. The ENC Utility will allow graphical, point-and-click configuration of your network routing, then configure each ESTeem wireless modem for the network as designed (Figure 1).
CHAPTER 4 UTILITIES & FEATURES ESTEEM DISCOVERY UTILITY The ESTeem Discovery Utility will allow you to configure the IP address on the Model 195Ea to match your network regardless of its current IP subnet. This utility will also allow you to update the software in the 195Ea and open the web configuration for that wireless modem. Installation To install the Discovery Utility on your computer, insert the Resource Disk in your CD drive.
CHAPTER 4 UTILITIES & FEATURES Note: This program is saved in a compressed file format. Microsoft Windows XP® will open the file directly, but other operating systems will require a common compression program such as WinZip available for download at http://www.winzip.com 3. Double click on the 195EDiscoverySetup.exe file listed in the window to install the program. Figure 4: Discovery Program Main Page 4.
CHAPTER 4 UTILITIES & FEATURES Firmware Updates To update firmware on any ESTeem Model 195 that is shown on the Discovery program, “right-mouse” click on the 195’s MAC address and select Update from the menu (Figure 6). Once you locate the update file, select the Open button and the 195 will update, validate and then reboot with the updated operating system.
CHAPTER 4 UTILITIES & FEATURES ETHERSTATION STATUS PROGRAM When configured for EtherStation mode, the Web Configuration Manger is turned off. To gather information from the 195Ea on Access Point, link status and received signal strength you will need to install the ESTeem 195E Status Utility. The EtherStation Status Utility version 2.0.0.0 or greater provides a new feature that will automatically program the connected ESTeem 195Ea to match up with the computer running the software.
CHAPTER 4 UTILITIES & FEATURES SETTING LOCAL TIME The ESTeem Model 195Ea will be shipped from the factory with the internal real-time clock set to Pacific Time. To change the clock settings to the local time for accurate log file entries: 1. Select Advanced from the top Menu, then Wireless LAN Settings>wlan0 device. Press the Next button (Figure 9). 2. Select Global Settings>Set System Time from the menu and press the Next button to continue. 3.
CHAPTER 4 UTILITIES & FEATURES CONFIGURING TIME SERVER Enabling NTP time synchronization services on the ESTeem 195Ea will allow usage of time services from upstream services to keep the time on the system accurate. To allow time synchronization, the Model 195Ea must be configured with the NTP Daemon enabled and the appropriate IP address of the upstream network NTP server. 1. Select Advanced from the menu items and Global Variables (Figure 11). Figure 11: Advanced Settings Menu 2.
CHAPTER 4 UTILITIES & FEATURES 3. The NTP daemon is enabled by selecting YES for NTP ENABLE (Figure 12). When enabled, the NTP daemon will use time services from upstream services to keep the time on this system accurate. 4. Next, the NTP SERVICE ENABLE should be configured to “YES,” if you want to allow the system to provide NTP service for clients wishing time synchronization (Figure 12). Figure 12: NTP Settings 5.
CHAPTER 4 UTILITIES & FEATURES 6. Once configuration is complete, press the Return to Advanced button. 7. To complete the configuration, select “Commit and Reboot.” The ESTeem 195Ea will now commit the configuration changes and reboot. (Figure 13) Figure 13: Advanced Settings Menu VLAN OPERATION Virtual LAN (VLAN) systems are rapidly becoming the desired configuration on larger Ethernet networks.
CHAPTER 4 UTILITIES & FEATURES 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.
CHAPTER 4 UTILITIES & FEATURES 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.
CHAPTER 4 UTILITIES & FEATURES 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.
CHAPTER 4 UTILITIES & FEATURES 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.
CHAPTER 4 UTILITIES & FEATURES Multicast Encapsulation To enable Multicast Encapsulation, select Advanced>Wireless LAN Settings>wlan0 device and press the Next Button (Figure 18). Select wlan0_EncapsulateMulitcast to either Multicast (for all Multicast including Broadcast) or Broadcast (Broadcast only). Press the Accept Button and then Commit and Reboot.
CHAPTER 4 UTILITIES & FEATURES Simple Network Management Protocol (SNMP) The ESTeem 195Ea supports SNMP Version 1 (SNMPv1) and Version 2 (SNMPv2c) protocol. This protocol enables any SNMP server to view the status of the wireless network while the system is in operation.

CHAPTER 6 SERIAL APPLICATIONS USING THE RS-232 PROGRAMMING PORT Any terminal emulation program that can run with VT100 emulation can be used for this configuration of the ESTeem. Most Windows users will probably use either Hyper Terminal or the Terminal Emulation in the ESTeem Utility program. Configure your RS-232C port for a Baud Rate to 38,400, Data Bits to 8, Parity to None, Stop Bits to 1 and Handshaking to None. Set the Emulation type to VT100.
CHAPTER 6 SERIAL APPLICATIONS Note: All characters are lower case. 10. To set the IP address in the ESTeem 195Ea, type the letter “A” and press the Enter key. Enter the value for the IP address, Netmask and default route pressing the Enter key after each entry. Figure 2: RS-232 Welcome Screen 11. After the basic parameters have been entered into the Model 195Ea you will need to commit the changes to the Model 195Ea (Figure 3). Press the C key and then Enter. The changes will be saved to flash memory.
CHAPTER 6 SERIAL APPLICATIONS 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.
CHAPTER 6 SERIAL APPLICATIONS Figure 6: Serial Configuration Screen 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.
CHAPTER 6 SERIAL APPLICATIONS 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.
CHAPTER 6 SERIAL APPLICATIONS 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.
CHAPTER 7 REPEATING FEATURES 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.
CHAPTER 7 REPEATING FEATURES 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.
CHAPTER 7 REPEATING FEATURES 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.
CHAPTER 7 REPEATING FEATURES 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.
CHAPTER 7 REPEATING FEATURES 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.
CHAPTER 8 ANTENNA SETUPS ANTENNA AND CABLE CONFIGURATIONS Warning: Only the tested cable lengths and antennas provided by EST meet the FCC and DOC maximum peak output power requirements. Any other combination of antennas or coax cables is not authorized. EST offers different types of antennas for both indoor and outdoor configurations.

APPENDIX C INTERFACE PORTS ETHERNET INTERFACE The ESTeem Model 195Ea’s Ethernet Port is a Full and Half-Duplex Auto-negotiation interface supporting both 10 Mbps and 100 Mbps (10/100BaseT). The Ethernet port is compliant with IEEE 802.3at High-Power Over Ethernet (PoE) to provide data and power over the same CAT-5E grade Ethernet cable. The port is compatible with TIA/EIA-568B cable configuration (Figure 1).
APPENDIX C INTERFACE PORTS CONFIGURING DHCP SERVER The ESTeem 195Ea Ethernet port supports both client and server Dynamic Host Configuration Protocol (DHCP). Figure 2 shows the DHCP host configuration screen that will be shown if DHCP server is selected in the setup screens. Enter the values that match the DHCP configuration for your network.
APPENDIX C INTERFACE PORTS RS-232C PROGRAMMING PORT CONFIGURATION RS-232 Programming Port The ESTeem Model 195Ea has a proprietary RS-232C interface in a RJ-45 connector on the front panel. To interface the 195Ea to the serial port on the computer, you need ESTeem cable AA0621 that combines a standard Ethernet patch cable to a 9-pin Female adapter. The serial port on the ESTeem Model 195Ea can be used to access the configuration menu in the ESTeem for system and network configuration.
APPENDIX D RADIO CONFIGURATION 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.
APPENDIX D RADIO CONFIGURATION Max (Maximum) Hi (High) Lo (Low) Min (Minimum) 1 Watt 700 mw 500 mw 250 mw Figure 3: Advanced Global Variables Figure 4: Power Level Settings Revised: 6 Sep 11 APX D-2 EST P/N AA107A
APPENDIX D RADIO CONFIGURATION AVERAGE RF OUTPUT POWER The average measurable output power on the ESTeem Model 195Ea will vary from 24dBm to 30dBm depending upon modulation type and RF data rate. The average power is used when entering the output power level in the ESTeem RF Design program.
APPENDIX E SECURITY 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.
APPENDIX E SECURITY 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.
APPENDIX E SECURITY 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.
APPENDIX F TROUBLESHOOTING 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 LED Solid Red on Link 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.
APPENDIX F TROUBLESHOOTING 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.
APPENDIX F TROUBLESHOOTING Figure 4: Rate Control Information 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.
APPENDIX F TROUBLESHOOTING 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).
APPENDIX F TROUBLESHOOTING 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.
APPENDIX F TROUBLESHOOTING 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.
