APPENDIX C INTERFACE PORTS 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).
APPENDIX C INTERFACE PORTS CONFIGURING DHCP SERVER The ESTeem 195Eg 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 195Eg has a proprietary RS-232C interface in a RJ-45 connector on the front panel. To interface the 195Eg 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 192E can be used to access the configuration menu in the ESTeem for system and network configuration.
APPENDIX D RADIO CONFIGURATION 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.
APPENDIX D RADIO CONFIGURATION Figure 2: Advanced Data Rate Selection 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.
APPENDIX D RADIO CONFIGURATION 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.
APPENDIX D RADIO CONFIGURATION 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) 1 2 5.
APPENDIX E SECURITY 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).
APPENDIX E SECURITY 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.
APPENDIX E SECURITY 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.
APPENDIX F TROUBLESHOOTING 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 LED Solid Red on Link 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.
APPENDIX F TROUBLESHOOTING 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.
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 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 UPDATING MODEL 192E TO OPERATE WITH 195EG The ESTeem Model 192E can be used in a Model 195Eg system but does require an update to the firmware. Once the 192E firmware has been updated, all the programming instructions in this User’s Manual will be applicable. The following firmware update procedure requires the ESTeem 192E to first be updated to firmware version 220.19. Once this has been verified, please proceed. Local FTP Server 1.
APPENDIX F TROUBLESHOOTING 6. Using an Internet Explorer or other web browser, open the internal WebPage of the local ESTeem192E you wish to upgrade. A hardwired Ethernet connection to the modem is required. 7. Configure the 192E in the Ethernet Only mode, make changes permanent and reboot. 8. Choose Run Script 9. When prompted for the script URL input the following command string and submit: ftp:///192epdrs.sh> Example: ftp:// 172.16.1.1/192epdrs.sh 10.
APPENDIX F TROUBLESHOOTING LONG RANGE POINT TO POINT APPLICATIONS The factory configuration on the 195Eg 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 195Eg’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 7).
