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:

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
