Release Notes PN 93000531 Digi Connect Wi-EM 82000983_E1 EOS August 13, 2004 INTRODUCTION This is a production release of firmware for the Digi Connect Wi-EM. SUPPORTED PRODUCTS Digi Connect Wi-EM ENHANCEMENTS None. BUG FIXES Fixed issue with wireless failing to work properly at cold temperatures. Fixed problem where socket connections to serial were not always draining completely after the socket disconnected (#14000). KNOWN ISSUES It is not currently possible to configure the escape characters used by client applications (connect, telnet, and rlogin). When attempting to upgrade the firmware on a unit which has password authentication enabled, this release requires one to disable passwords during the time period of the firmware upgrade. When attempting to replace files in the file system, simply overwrite the existing version of the file rather than deleting the file first. Attempting to delete the file first defeats the internal file versioning maintained by the firmware, and can confuse your browser's cache. For the most consistent experience with the user interface, it is suggested that you clear your Internet cache. Microsoft Internet Explorer 6 Service Pack 1 (SP1) has a known problem where it displays the error message "Internet Explorer Cannot Open" when you use an HTTPS URL to access this Digi product. The following Microsoft article explains the problem: http://support.microsoft.com/default.aspx?kbid=812935 DOCUMENTATION ERRATA Password authentication can be enabled in this release, but authentication is OFF BY DEFAULT. A security screen has been added to the user interface to allow one to enable username and password authentication. When password checking is enabled, the user will be challenged when accessing the initial screen of the UI or if the user uses the Digi Device Discovery tool. CONNECTING TO THE WIRELESS DEVICE The device can only be configured over the wireless link with an access point. In order to establish a wireless link the access point must have authentication and encryption disabled. Furthermore to ensure that the Connect Wi-EM establishes a link with the correct access point the access point should use the SSID of "Connect". By factory default our device scans through each wireless channel and generates a list of access points. It then associates with the access point with the strongest signal strength. However it will choose to associate with an access point with SSID of "Connect" over another access point that has a different SSID regardless of which access point has the stronger signal strength. When the device successfully associates with an access point its link LED will go solid. CONFIGURING THE WIRELESS DEVICE Once link has been established the device can be discovered using the "Digi Device Discovery" tool. Using this tool you can find the device and if necessary assign it an IP address. Once the IP address has been determined or established you can configure it using a web browser or telnet. If at any point the device is configured in a state that it can no longer be connected to, a factory reset can be done as described below in the "RESETTING THE UNIT" section. IP ASSIGNMENT NOTES The Digi Connect Wi-EM supports three IP assignment methods: * Static IP address * DHCP * Auto-IP If a static address is enabled, it will be used. If a static address is not enabled, and DHCP is enabled, the unit will use an address supplied by a DHCP server regardless of the state of Auto-IP configuration. If a static address is not enabled, and Auto-IP is enabled, it will be used to generate an address ONLY if DHCP is disabled, or if DHCP is enabled and a DHCP server has not responded to the DHCP query. If both are enabled, Auto-IP has assigned an address, and then a DHCP server responds, the Auto-IP address will be discarded and the DHCP address will be used. RESETTING THE UNIT One feature of the Digi Connect Wi-EM firmware is an ability for a user to both soft reset the unit as well as reset the unit to its factory defaults. Both functions may be invoked via the "reset" button on the edge of the module, labelled SW1 on the board. * If the module is running (i.e. more than a few seconds after power on), holding the button for a second and then releasing it will soft reset the unit. * If the button is pressed for more than 10 seconds from the power on of the unit, it will prepare to reset the unit to its factory default state. Once the unit is prepared to reset, it will blink "1-5-1" on the red LED. Releasing the button will then reset the configuration. ADDITIONAL INFORMATION The configuration save and restore tools will save every configurable parameter (including IP configuration) except for those related to password authentication. ENABLING THE WEB USER INTERFACE The embedded web user interface is ALWAYS available at the following URL: http://ip-address-of-device/home.htm It is also available as the default configuration interface at the following URL: http://ip-address-of-device If your device contains the Java configuration applet it can be executed by connecting to the embedded web user interface and clicking the "Launch" button on the "Home" page under the "User Interfaces". It can be made to be the default configuration interface by clicking the "Set as Default" button on the same page. The Java Configuration Applet may remain in the unit's file system without affecting the embedded web user interface. If you would like to use the Java Configuration Applet as an alternative, simply upload the index.htm file as a file with an alternate name (e.g. applet.htm). You would then be able to use the Java Configuration Applet by accessing the following URL: http://ip-address-of-device/applet.htm HISTORY 82000983_E Initial product release. 82000983_1P Pilot release.
