CHAPTER 5 EXAMPLE CONFIGURATIONS Revised: 23 Jan 08 5-1 EST P/N AA107G PROGRAMMING EXAMPLES In this chapter we will demonstrate how to program the ESTeem Model 195Eg for each of the operating modes. For a detailed explanation of the modes, please refer to Chapter 1 of this manual. In the following examples we assume that the modems have been initially configured for IP Address, Net Mask, etc. and are ready for programming from the Model 195Eg’s Web Configuration Manager’s Setup Menu. The first example network in Figure 1 consist of two wired Ethernet networks (Large Plant LAN and Remote Building) that will be bridged together through a repeater site and have a direct backup pathway. This same wireless mesh canopy will provide wireless access to the single PLC on the forklift (Example 4) and any other 802.11g or 802.11b devices. The second example network in Figure 2 show how to configure the Model 195Eg if multiple Ethernet devices are connected to a single ESTeem Model 195Eg. A separate network address for the connected hardware is required and can be configured for fixed or dynamic IP (DHCP) addressing. The use of multiple network addresses will require that a network router be programmed for each of the remote devices. As we learned in Chapter 1 of this manual, the difference in the Station Router and the Station Masquerade Mode will depend upon the required availability of accessing the connected Ethernet devices to the 195Eg. The Station Router will allow devices on the Ethernet LAN to access these device and the Station Masquerade will not, very similar to a firewall.

CHAPTER 5 EXAMPLE CONFIGURATIONS Revised: 23 Jan 08 5-3 EST P/N AA107G Example 1 – Plant Network (Access Point Router with Repeater Enabled) The ESTeem Model 195Eg configured as an Access Point Router will provide a separation between the larger Plant network and the Ethernet devices connected on the wireless network. This mode of operation is most often used when connecting the wireless system to a larger network to eliminate the Network broadcast traffic from entering the wireless system. If Ethernet devices on the Plant network want to access Ethenet devices on the wireless network, a network router is required to resolve the IP conflict created by having the wired and wireless networks on separate subnets. 1. Access the ESTeem Web page using your computer’s Web Browser as per instructions in Chapter 4. Select Setup from the menu items. From the Select Mode of Operation pull down box , select AP Router (Figure 4) and push the Next button below the pull down box.

Figure 7: DHCP Wireless Port Figure 8: Wireless IP Address
CHAPTER 5 EXAMPLE CONFIGURATIONS Revised: 23 Jan 08 5-6 EST P/N AA107G 6. Enter the default route (Gateway) address for the network. This AP Router 195Eg will use the Network Router for address resolution (Figure 3). Enter the IP address for the Network Router and any DNS server information. If you are not connecting the Model 195Eg to the Internet, leave blank and press the Next button. Figure 9. 7. Select Yes if you will be using security for client access to your wireless network (recommened). NOTE: The setting of this security level is ONLY for client access to the Model 195Eg. The security of the Bridge communication between the Model 195Eg’s is separate and will be configured during the repeater configuration. Enter the SSID for your 802.11g network. The SSID is the unique identification for your wireless network and all 802.11g devices that share a wireless network MUST have the same SSID code. This identification code is case sensitive and must NOT contain spaces. Reference Figure 10. Figure 9: Wireless Security Level Settings Figure 10: WEP Key Entry
CHAPTER 5 EXAMPLE CONFIGURATIONS Revised: 23 Jan 08 5-7 EST P/N AA107G 8. Select the encryption level for the wireless client access to the network. For further information on the different levels of security, please refer to Appendix E – Security of this User’s Manual. If you would like to hide the SSID from broadcasting from the Access Point and would like to discard the broadcast probes select Yes. If Yes is selected the Model 195Eg will no longer send out periodic SSID radio beacons that can be identified with 802.11b network scanning software. The users of the network will have to know the SSID to enter the network and security is increased, but if you want the SSID to be broadcast to the network for easy identification then select No. In our example, we will be using mobile clients with 128 bit WEP. Reference Figure 11. 9. Enter the WEP key values for your application that will be used by all devices on the wireless network. Reference Figure 12. Figure 11: Security Selection Figure 12: WEP Key Input Screen
CHAPTER 5 EXAMPLE CONFIGURATIONS Revised: 23 Jan 08 5-8 EST P/N AA107G 10. Enter the values for the Access Control List (ACL). This is a configurable MAC filter that can be set to allow or deny specific wireless MAC address to the network. This feature is further explained in Appendix E – Security. In our example we will not use the ACL. Reference Figure 13. 11. Select the frequency channel of operation. All Access Points in the same Repeater Peer network need to be on the same radio frequency channel. See Appendix D – Radio Configuration for help in selecting the frequency channel. Reference Figure 14. Figure 13: Access Control List Settings Figure 14: Radio Channel Selection
CHAPTER 5 EXAMPLE CONFIGURATIONS Revised: 23 Jan 08 5-9 EST P/N AA107G 12. The Repeater Peer Table (Figure 15) identifies which Model 195Eg’s will bridge wireless Ethernet communication. Only other Access Point Repeaters need to be listed not the Model 195Eg’s in client modes. Multiple links to the same destination will provide a backup pathway (Mesh Network) if the primary pathway is lost. Looking at the system layout in Figure 1, both the repeater site and the direct link will be listed. Using the System Configuration Table (Table 1) as a guide, enter the Wireless (WLAN) MAC address for the 195Eg’s that will communicate with the Access Point Router (Example 1) starting with the primary repeater path through the stand-alone repeater. The communication link through repeater site is the best radio path from the Plant Network to the Remote Building and we want this link to be the primary repeater route. The 195Eg follows the same networking “rules” as any other Ethernet device and if we made no changes to the default path cost of 100 the lowest path cost would be directly to the Remote Building (Direct = 100, Repeater = 200 (100+100)). To configure the 195Eg to select the repeater as the primary radio path, the direct link’s path cost must be greater than the cost through the repeater link (any number greater than 200). We will set the path cost at 201 for the direct link, making the repeater link a lower path cost and thus the primary pathway. Press the Add button to enter the first repeater link to the Repeater Peer List and Figure 16 will be displayed. Note: For a more complete description on configuring repeater routes, see Chapter 6 – Repeating Features. Figure 15: Blank Repeater Table
CHAPTER 5 EXAMPLE CONFIGURATIONS Revised: 23 Jan 08 5-10 EST P/N AA107G First Repeater Link - Enter the Wireless (WLAN) MAC address of the stand-alone repeater site and the path cost for this link will stay at the default value at 100. Select the level of Encryption for this communication link. The encryption levels for the repeater peer link must be the same on both sides, but is completely independent from the Encryption level for the client access to the network. For consistency in our example, we will also use 128-Bit WEP Encryption for the Repeater Peer link. Setting the link data rate to Dynamic will allow all data rates from 1 Mbps to 54 Mbps to be used. Verify the Repeater Link is set to Enable and press the Create Repeater Peer Button. Figure 16: First (Primary) Repeater Link
CHAPTER 5 EXAMPLE CONFIGURATIONS Revised: 23 Jan 08 5-11 EST P/N AA107G Second Repeater Link (Direct Path) - Press the Add button a second time (Figure15) and Figure 17 will be displayed. Enter the Wireless (WLAN) MAC address of the Remote Building and set the path cost for this link to a value of 201. Select the level of Encryption for this communication link. The encryption levels for the repeater peer link must be the same on both sides, but is completely independent from the Encryption level for the client access to the network. For consistency in our example, we will also use 128-Bit WEP Encryption for the Repeater Peer link. Setting the link data rate to Dynamic will allow all data rates from 1 Mbps to 54 Mbps to be used. Verify the Repeater Link is set to Enable and press the Create Repeater Peer Button. Figure 17: Second (Backup) Repeater Link
CHAPTER 5 EXAMPLE CONFIGURATIONS Revised: 23 Jan 08 5-12 EST P/N AA107G Figure 18 displays the complete repeater peer list with both repeater peer entries. Set Enable repeater capability to Yes and to both repeater paths. This Access Point Router 195Eg is also the primary data path for all Ethernet traffic on the network and will also need to be configured as the Root Bridge. Press the Next button to continue. 13. Figure 19 will be displayed. If no further changes are necessary to the modem, you can commit the changes that will then be saved and the modem rebooted.

CHAPTER 5 EXAMPLE CONFIGURATIONS Revised: 23 Jan 08 5-13 EST P/N AA107G Example 2 – Stand Alone Repeater (Access Point Bridge with Repeater Enabled) Review the example diagram, Figure 1, and locate the 195Eg marked as Example #2. This ESTeem is being used by two other Model 195Eg’s as a repeater but is not connected to an Ethernet network. This modem should be configured for Access Point Bridge mode. 1. Access the ESTeem Web page using your computer’s Web Browser as per instructions in Chapter 4. Select Setup from the menu items. From the Select Mode of Operation pull down box , select AP Bridge (Figure 20) and push the Next button below the pull down box. 2. Select if you want to use client or server Dynamic Host Configuration Protocol (DHCP) for the 195Eg. If you want to enter a static IP address for the Model 195Eg, select Off and press the Next button. For our example, we have fixed IP addresses and will select Off. Reference Figure 21. Figure 20: Access Point Bridge Figure 21: DHCP Configuration
CHAPTER 5 EXAMPLE CONFIGURATIONS Revised: 23 Jan 08 5-14 EST P/N AA107G 3. Enter the bridge IP Address and IP Netmask for the Model 195Eg. You will notice that for the 195Eg in AP Bridge mode only a single IP address in entered. Both the ethernet IP and wireless IP addresses will be the same in the bridge mode. Reference Figure 22. 4. Enter the default route (Gateway) address for the network. For Ethernet devices on the wireless network (IP 172.16.X.X – See Figure 3), the AP Router 195Eg will be the gateway. Enter the wireless IP address for the AP Router 195Eg (configured in Example 1) and any DNS server information. If you are not connecting the Model 195Eg to the Internet, leave blank and press the Next button. Figure 23. Figure 22: Bridge IP Addresses Figure 23: Default Route (Gateway) and DNS Configuration
CHAPTER 5 EXAMPLE CONFIGURATIONS Revised: 23 Jan 08 5-15 EST P/N AA107G 5. Select Yes if you will be using security for your wireless network (recommened). NOTE: The setting of this security level is ONLY for client access to the Model 195Eg. The security of the Bridge communication between the Model 195Eg’s is separate and will be configured during the repeater configuration. Enter the SSID for your 802.11g network. The SSID is the unique identification for your wireless network and all 802.11g devices that share a wireless network MUST have the same SSID code. This identification code is case sensitive and must NOT contain spaces. Reference Figure 24. 6. Select the encryption level for client access to the wireless network. For further information on the different levels of security, please refer to Appendix E – Security of this User’s Manual. If you would like to hide the SSID from broadcasting from the Access Point select Yes. If Yes is selected the Model 195Eg will not send out periodic SSID radio beacons that can be identified with 802.11b network scanning software. The users of the network will have to know the SSID to enter the network and security is increased, but if you want the SSID to be broadcast to the network for easy identification then select No. The 195Eg can also be configured to discard the probe requests from 802.11g clients. If desired, set Discard Broadcast Probes to Yes. In our example, we will be using mobile clients with 128 bit WEP. Reference Figure 25. Figure 24: Security and SSID Configuration Figure 25: Encryption Level Selection
CHAPTER 5 EXAMPLE CONFIGURATIONS Revised: 23 Jan 08 5-16 EST P/N AA107G 7. Enter the WEP key values for your application that will be used by all devices on the wireless network. Reference Figure 26. 8. Enter the values for the Access Control List (ACL). This is a configurable MAC filter that can be set to allow or deny specific wireless MAC address to the network. This feature is further explained in Appendix E – Security. In our example we will not use the ACL. Reference Figure 27. Figure 26: WEP Key Entry Figure 27: ACL Configuration
CHAPTER 5 EXAMPLE CONFIGURATIONS Revised: 23 Jan 08 5-17 EST P/N AA107G 9. Select the frequency channel of operation. All Access Points in the same Repeater Peer network need to be on the same radio frequency channel. See Appendix D – Radio Configuration for help in selecting the frequency channel. Reference Figure 28. 10. The Repeater Peer Table identifies which Model 195Eg’s will bridge wireless Ethernet communication. Only other Access Point Repeaters need to be listed not the Model 195Eg’s in client modes. Looking at the system layout in Figure 1 and what we discussed in Example 1, both the Plant Network’s 195Eg and the Remote Building’s 195Eg will be listed by their wireless (WLAN) MAC (Figure 29). There is only a single radio connection path to the other two 195Eg’s in the network. The path cost only effects redundant links in the network (not applicable to the repeater) and will be left at default. Enter the WLAN MAC addresses for the other two Access Points and press the Next button to continue. 11. Select Commit Changes to write the programming to Flash memory and reboot the Model 195Eg. When the reboot process has completed (approximately 30 seconds) the modem will be ready to place in operation. Figure 28: Channel Configuration Figure 29: Repeater Configuration
