Release Notes PN 93000780_F5 Digi Connect Wi-SP 82001220_F5 EOS September 21, 2005 INTRODUCTION This is a production release of firmware for the Digi Connect Wi-SP. The Digi Connect Wi-SP device server is the ideal solution for web and network-enabled applications by delivering a powerful, compact and customizable device networking solution for both "plug-and-play" and custom application environments. SUPPORTED PRODUCTS Digi Connect Wi-SP ENHANCEMENTS Control flashing of 1-1-1 to allow faster boot up. Added a new feature to set the initial level of GPIO output states to a user configurable setting. (Vantive 16384) Added new feature to allow upload of customization files using Connect Programmer. Add support for a user-configurable DHCP host name (DHCP Option 12) to the Digi Connect family of products. (Vantive 14648) Included support in all Wireless Connect Products for channels 1-13 in Spain and France. (Vantive 16419) BUG FIXES Corrected regression where file upload using the Connect Programmer was not showing up in the web UI. (Vantive 15771) Added logic to re-establish a TCP socket connection after a remote host becomes drops off line. (Vantive 16396) With the latest combination of POST firmware and embedded operating system, the Digi Connect device servers now offer the ability to select whether some of their power-on self tests will be executed or skipped. The new default behavior of the POST will be to skip some of its tests, including the test of the diagnostic LED which blinks 1 - 1 - 1 before running the EOS. Skipping the tests enables the device to boot more quickly. With a CLI command in the EOS, customers will be able to choose to execute the tests, restoring the previous POST behavior. The new CLI commands are: boot postaction=display boot postaction=skip boot postaction=execute KNOWN ISSUES The current hardware doesn't allow user to set less than 6 dBm wireless transmit power. With encryption set to AES, serial throughput will be lower than usual It is not currently possible to configure the escape characters used by client applications (connect, telnet, and rlogin). If the standard web service (HTTP) is disabled, the encrypted web service (HTTPS) stops operating. They will be made independently selectable in a future release. In order to clear the persistent storage from the CLI one can execute the "boot action=factory" command. The only web accessible method for clearing the storage is available via the reset functionality in the administrative pages at "admin/factory_defaults.htm". 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. 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 CONNECTING TO THE WIRELESS DEVICE The device can be configured over the wireless link with an access point or by automatically enabling the CLI on the serial port. In order to establish a wireless link the access point must have authentication and encryption disabled. Furthermore to ensure that the Connect Wi-SP 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 using the reset button on the bottom of the unit. IP ADDRESS ASSIGNMENT NOTES The Digi Connect Wi-SP 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. ADDITIONAL INFORMATION In order to automatically enable the CLI on the serial port: - The device should be powered down - All of the MEI switches should be placed in the ON position (normally an invalid setting that puts the serial port in an electrical loop back mode) - Connect an RS-232 console device to the serial port, configured with the speed, parity, and stop bits that are specified in the serial port configuration - Power the device up and use the CLI - When complete, power the device down, place the MEI switches in their normal positions, and power the unit back on The new "set wireless transmit power" feature is not currently documented in the CLI and RCI manuals. In the CLI, it is added as a parameter on the set/show wlan command. In the "show wlan" command, it is displayed as: txpower : 6dbm and in the "set wlan" it has the following syntax: set wlan [txpower={16dbm | 14dbm | 12dbm | 10dbm | 8dbm | 6dbm}] In the RCI, it is part of the data group and its field is . The following values are valid for the txpower field: 16dbm, 14dbm, 12dbm, 10dbm, 8dbm, and 6dbm. The configuration save and restore tools will save every configurable parameter (including IP configuration) except for some 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 82001220_F1 Initial production release Enabled the CLI PING command on this device WPA enhancements: - TLS, TTLS, and PEAP authentication methods - CHAP, GTC, MD5, MSCHAP, MSCHAPv2, OTP, and PAP authentication methods for use with TTLS and PEAP - Client certificates for use with TLS - Verification of server certificates - CCMP (AES) encryption Wireless networking enhancements: - Separate authentication and encryption settings - WEP with 802.1x authentication - Cisco LEAP - Settings for short preamble and antenna diversity (Wi-EM only) - Display current authentication, encryption, and network statistics Added the option of enabling the CLI on a serial port
