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 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.

CHAPTER 5 EXAMPLE CONFIGURATIONS Note: Throughout the Configuration Manager are Help Screens that can accessed for further information on each item. 2. Select if you want to use client or server Dynamic Host Configuration Protocol (DHCP) for the Ethernet device. 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.
PAGE 5
CHAPTER 5 EXAMPLE CONFIGURATIONS 4. Select if you want to use client or server Dynamic Host Configuration Protocol (DHCP) for the Wireless device. 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. For more information on the operation and configuration of DHCP, please refer to Appendix C – Interface Ports. Reference Figure 7. Figure 7: DHCP Wireless Port 5.
PAGE 6
CHAPTER 5 EXAMPLE CONFIGURATIONS 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. Figure 9: Wireless Security Level Settings 7. Select Yes if you will be using security for client access to your wireless network (recommened).
PAGE 7
CHAPTER 5 EXAMPLE CONFIGURATIONS 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.
PAGE 8
CHAPTER 5 EXAMPLE CONFIGURATIONS 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. Figure 13: Access Control List Settings 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.
PAGE 9
CHAPTER 5 EXAMPLE CONFIGURATIONS 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.
PAGE 10
CHAPTER 5 EXAMPLE CONFIGURATIONS 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.
PAGE 11
CHAPTER 5 EXAMPLE CONFIGURATIONS 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.
PAGE 12
CHAPTER 5 EXAMPLE CONFIGURATIONS 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. Figure 18: Completed Repeater Peer List 13. Figure 19 will be displayed.
PAGE 13
CHAPTER 5 EXAMPLE CONFIGURATIONS 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.
PAGE 14
CHAPTER 5 EXAMPLE CONFIGURATIONS 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. Figure 22: Bridge IP Addresses 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.
PAGE 15
CHAPTER 5 EXAMPLE CONFIGURATIONS 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.
PAGE 16
CHAPTER 5 EXAMPLE CONFIGURATIONS 7. Enter the WEP key values for your application that will be used by all devices on the wireless network. Reference Figure 26. Figure 26: WEP Key Entry 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.
PAGE 17
CHAPTER 5 EXAMPLE CONFIGURATIONS 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. Figure 28: Channel Configuration 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.
