[. . . ] The left (yellow) LED indicates network activity. It is on by default, turning off when network activity occurs at the Ether-Serial Link. The right (green) LED indicates a network link. It is off by default, but lights when a network link exists. 3 4. [. . . ] If your network assigns IP addresses using a DHCP server, DHCP detection can also be enabled. The Ether Link Manager can also auto-configure a link when a DNS server is used. Changes made using the Ether Link Manager will be updated to both the local PC and to the Ether Link. NOTE: Changing the network settings of an Ether Link device may make that device unavailable to other stations that have activated a connection to that device using older network settings. NOTE: The Ether Link Manager is the recommended method of changing all Ether-Serial Link settings. 7 Configuring Ether Link network settings using a web browser To set an Ether Link's network settings using a web browser, open the browser and enter the IP address of the Ether Link into the browser's location bar. The embedded web server running on the Ether Link will display the opening screen of the EtherSerial Link configuration menu. In the configuration screen that appears, enter the network settings you wish for that Ether Link. Once the new values are entered and accepted, the Ether-Serial Link will reboot to implement the new network settings. Changes made using a web browser will be updated to the Ether Link but not to the local PC. NOTE: Changing the network settings of an Ether Link device may make that device unavailable to other stations that have activated a connection to that device using older network settings. 8 Configuring Ether Link network settings using a Telnet client To set an Ether Link's network settings using a Telnet client, open a Telnet session to the IP address of the link whose settings you want to change. Details on Telnet connection can be found in the "telnet. pdf" file on the Installation diskette. Note on subnet configuration If the Ether-Serial Link is on a different subnet from a client station that is attempting to access it, the Ether-Serial Link will be visible in an instance of the LAVA Ether Link Manager running on the client station, and its ports can be activated on that client station, but applications running on the client station will not be able to open a serial port on the Ether-Serial Link. For example, if the IP address of the Ether-Serial Link is 192. 168. 0. 35 and the IP address of the client station is 192. 168. 1. 1, the two devices are on different subnets (as indicated by the difference between the "0" and the "1" in the third portion of the two IP addresses). Two solutions exist: · change the subnet of the either the Ether-Serial Link or the client station so that they are both on the same subnet or, · change the subnet mask of the Ether-Serial Link to encompass both subnets. By default, the Ether-Serial Link has its subnet mask set to 255. 255. 255. 0. This setting excludes all but the fourth portion of the IP address when assessing IP addresses. In the example above, a subnet mask of 255. 255. 0. 0 will include the Ether-Serial Link in both subnets. 9 C. Activating & Deactivating Ether Link ports Ether Link ports that have been detected as existing on the network are not initially activated for your PC. To access an EtherSerial port it must be activated. You may wish to activate on a given computer some, all, or none of the Ether Link ports that are available on the network. To activate a particular port, right click on the port where it is displayed in the right panel of the Ether Link Manager, and select "Activate". To activate all ports on a particular Ether-Serial Link device, right click on that device in the left panel of the Manager and select "Activate All" . Before activation, Ether Link ports only appear under the "My Ether Link Network" branch of the Ether Link Desktop. Once they have been activated for a local system, they will also appear under "My Computer" in the Ether Link Manager. To deactivate ports individually, rightclick on the port where it is displayed in the right panel of the Ether Link Manager, and select "Deactivate". To deactivate all ports on a particular Ether-Serial Link device, right click on that device in the left panel of the Manager and select "Remove All" . 10 Icons depict the states of Ether Link devices and ports as follows: Device available on the network Device not available on the network Under "My Computer": Port available Under "My Ether Link Network": Port activated locally Under "My Computer": Port not available Under "My Ether Link Network": Port not activated locally Activated ports appear in Windows' Device Manager under the "Ports (COM & LPT)" branch as "Lava Virtual Port" ports, with their associated COM numbers. Activating and deactivating Ether Link ports on one computer does not affect the operation of those ports on other systems. 11 D. Optional advanced port configuration Ether-Link ports that have been activated on your PC can generally be used immediately without further configuration. Additional configuration options can however be accessed through the Lava Ether Link Manager. These configuration options are discussed in detail in the "advanced. pdf" readme file on the Installation diskette. [. . . ] In the right hand pane you should find a new port titled "LAVA Ether-Serial Port (COMXX)" resembling the WAN activation icon. 13 10. Repeat step 8 for any additional WAN activations you wish to create. Configuration & installation when Ether-Serial Link is internal: NOTE: All steps assume the Ether-Serial Link has already been configured and is working on a public IP address. Obtain the IP address of the gateway/router that the EtherSerial Link is located behind. [. . . ]
