APPENDIX C INTERFACE PORTS Revised: 23 Jan 08 APX C-1 EST P/N AA107G ETHERNET INTERFACE The ESTeem Model 195Eg’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 802.3af Power Over Ethernet (PoE) to provide both data and power over the same CAT-5E grade Ethernet cable. The port is compatible with TIA/EIA-568B cable configuration (Figure 1). A second Ethernet port will be included if the serial option is added to the 195Eg. This second Ethernet port can be used in Bridge Mode (HUB) or as a router. Figure 1: Ethernet Pin Layout

APPENDIX D RADIO CONFIGURATION Revised: 18 Mar 08 APX D-1 EST P/N AA107G 195Eg FREQUENCY OF OPERATION In a wireless Ethernet network all of the ESTeem Model 195Eg’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 195Eg (reference Chapter 4). See Figure 1. RF COMMUNICATIONS DATA RATE The RF data rate of the Model 195Eg can be programmed for operation at 1, 2, 5.5, 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 195Eg from monitoring the received signal quality. The Model 195Eg can communicate with multiple 802.11g devices at different data rates for each device. By selecting all ranges from 1 to 54 Mbps you will be able to communicate with all 802.11g and 802.11b devices regardless of their generation, data rate, and signal quality requirements. Dynamic scaling means that the Model 195Eg 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 192E 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 192E will increase the RF data rate the next highest level. The ESTeem 195Eg is set at the factory to operate at maximized scaling speed data rates from 1-54 Mbps and should not need adjustment. The RF Data Rate is programmed in the Model 195Eg through the Advanced Menu>Wireless LAN Settings>Wlan0 Device and the value for wlan0_OPRATES:. In the example shown in Figure 2 the RF Date Rate is programmed to dynamic scale from 1 to 54 Mbps (recommend factory default setting). To set the values for the data rate, check the box next to the listed data rate to enable this rate for operation. Figure 1: RF Channel Selection Channel Number Frequency 1 2412 MHz 2 2417 MHz 3 2422 MHz 4 2427 MHz 5 2432 MHz 6 2437 MHz 7 2442 MHz 8 2447 MHz 9 2452 MHz 10 2457 MHz 11 2462 MHz
APPENDIX D RADIO CONFIGURATION Revised: 18 Mar 08 APX D-2 EST P/N AA107G RF BASIC RATE The RF Basic Rate is the synchronization rate used to establish the initial connection between 802.11g and 802.11b communication devices in Mbps. After the initial connection has been establish the RF communication rate will be determined by the RF Communication Data Rate established above. Factory default is 1 through 11 Mbps shown in Figure 2 so that the unity will establish communication with the older (slower) 802.11b devices. This lower rate also allows for a quicker reconnect when the ESTeems are configured for EtherStation mode or working in a mobile environment. The ESTeem 195Eg is set at the factory to operate at all speeds from 1-11 Mbps and should not need adjustment. The RF Basic Rate is programmed in the Model 195Eg through the Advanced Menu>Wireless LAN Settings>Wlan0 Device and the value for wlan0_AP_BASICRATES:. In the example shown in Figure 2 the RF Date Rate is programmed to dynamic scale from 1 to 11 Mbps (recommend factory default setting). To set the values for the data rate, check the box next to the data rate required. Note: The Model 195Eg will only communicate with slower speed devices after synchronization if the RF Communication Data shown above has been set to dynamically scale to 1 and 2 Mbps. In general, do not set the RF Basic Rates above 11Mbps unless specifically instructed by ESTeem Customer Support. Figure 2: Advanced Data Rate Selection
APPENDIX D RADIO CONFIGURATION Revised: 18 Mar 08 APX D-3 EST P/N AA107G SETTING RF POWER LEVEL The ESTeem Model 195Eg 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. Max (Maximum) 1 Watt Hi (High) ≈700 mw Lo (Low) ≈500 mw Min (Minimum) ≈250 mw Figure 4: Power Level Settings Figure 3: Advanced Global Variables
APPENDIX D RADIO CONFIGURATION Revised: 18 Mar 08 APX D-4 EST P/N AA107G AVERAGE RF OUTPUT POWER The average measurable output power on the ESTeem Model 195Eg 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. The following table provides that level and modulation type at each data rate: RF Data Rate (Mbps) Average Power Modulation Type 1 30dBm BPSK 2 30dBm BPSK 5.5 30dBm BPSK 6 30dBm OFDM 9 30dBm OFDM 11 30dBm BPSK 12 28dBm OFDM 18 28dBm OFDM 24 27dBm OFDM 36 27dBm OFDM 48 24dBm OFDM 54 24dBm OFDM
APPENDIX E SECURITY Revised: 23 Jan 08 APX E-1 EST P/N AA107G OVERVIEW The security for the ESTeem Model 195Eg, 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. 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. 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 uses 802.1x. However, a backend authentication server handles the authentication decision. The most commonly type of authentication server is a RADIUS server. The ESTeem Model 195Eg 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 195Eg can support WPA Enterprise and PSK as an Access Point, but the level of security on the Bridging layer is configured separately. 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.
APPENDIX E SECURITY Revised: 23 Jan 08 APX E-2 EST P/N AA107G 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 195Eg 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 195Eg 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 195Eg can be configured for WPA Enterprise for client level access, communicate to another ESTeem Model 195Eg using a TKIP bridge link and also communicate 128-Bit WEP to our older ESTeem Model 192E radio modems all running simultaneously. MASQUERADE MODES When the ESTeem Model 195Eg is configured in either the Access Point Masquerade or the Client Masquerade modes, the wireless modem functions 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. Set "Hide SSID" to True. As you take your access point out of the box, broadcast SSID is enabled which means that it will accept any SSID. By hiding the SSID configured in the client must match the SSID of the access point. 4. 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 5. Change the default SSID of your product. Don't change the SSID to reflect your company's main names, divisions, or products. It just makes you too easy to target. 6. 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.
APPENDIX E SECURITY Revised: 23 Jan 08 APX E-3 EST P/N AA107G 7. 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. 8. Consider using an additional level of authentication, such as Remote Access Dailin User Service (RADIUS), before you permit an association with your access points. While it's not part of the 802.11b standard, a number of companies are optionally including some provision for RADIUS authentication. 9. 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. 10. Don't buy Access Points or NICs that only support 64-bit WEP. 11. 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. 12. 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: 23 Jan 08 APX F-1 EST P/N AA107G TESTING COMMUNICATION LINK After you have configured at least two of the Model 195Eg 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 195Eg (Figure 1). If the Status light is solid, the Model 195Eg has a connection to another Model 195Eg 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 195Eg. Under the Wireless Status heading click on the View Peer Table (Figure 2). The Peer Table will list all other 802.11b or 802.11g wireless activity seen by the 195Eg 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: 23 Jan 08 APX F-2 EST P/N AA107G Repeater Peers - The Peer Table will display all connected 195Egs 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 195Eg. 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 195Eg 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: 23 Jan 08 APX F-3 EST P/N AA107G The value of the Current TX rate is the RF data rate between the two ESTeem Model 195Eg. 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 Revised: 23 Jan 08 APX F-7 EST P/N AA107G 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 195Eg firmware listed on the ESTeem Web site (www.esteem.com) under the Model 195Eg product page. How and when do I update the Model 195Eg firmware? - You should only update the Model 195Eg 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/195EG Do all firmware versions have to be the same to communicate between the Model 195Eg? – 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 195Eg? – The ESTeem Utility program is not required to program the Model 195Eg. The 195Eg 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 195Eg – The Model 195Eg 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 195Eg 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 195Eg 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 30 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 195Eg’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 195Eg 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 195Eg’s repeater tables. If only one side is configured, everything will appear to be correct but no communication will function.
APPENDIX F TROUBLESHOOTING Revised: 23 Jan 08 APX F-8 EST P/N AA107G EtherStation How do I access the Model 195Eg web page in EtherStation Mode? The Model 195Eg 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 192E 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 195Eg. The MAC address must have colons between the values. Can I connect my Model 195Eg 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 195Eg can only service ONE Ethernet device.

Ether a cross-over or patch cable is supported.Access Point ModeWireless LAN cards are not connecting – Verify that the wireless LAN cards are set to Infrastructure Mode, have a matchingSSID (or ESSIS) set the same as the Model 195Eg 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 onthe Model 195Eg match the wireless LAN card.Access Point Repeater ModeHow long does it take to re-establish the Wireless Ethernet Network? - If a communication link is lost and the Wireless Networkneeds to re-establish the repeater routes, the time can take up to 30 seconds.Should the AP Repeater Mode be used on mobile equipment? - The AP Repeater mode should be used on equipment that willnot change the Repeater Route as it moves. For example, if a mobile device such as a crane can communicate directly to anotherESTeem and will not loose the link in its travel, the AP Repeater Mode could be used. If the device requires two ESTeem Model195Eg’s (Base and Repeater) to maintain communication across its complete travel, the Station Modes should be used on themobile device. The problem will be in the time that the mobile ESTeem will take to transfer between the two sites. In AccessPoint 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 beconfigured the same way.Correct configuration, but cannot establish communications. – In addition to the network configuration, all 195Eg modemsconfigured in the AP mode must share the same SSID and be on the same frequency channel.
