Request via: http://www.digi.com/support/eservice/login.jsp?p=true. You will need to create a user account if one is not already set up.
When submitting a support request, please include a copy of the debug.txt file from the unit’s flash. This will greatly improve the quality of the initial response you receive. Without this file, it is often very difficult for the support team to provide accurate answers to your queries.

5.2 Unable to open the Web Interface
Ensure that the LAN cable is properly connected to the LAN port and that the “LAN” status indicator on the front of the unit is illuminated. If it is not, then there is a problem with either the LAN cable or the device it is connecting to. If the status indicator is illuminated, check that the PC can communicate with the unit. To do this, open the Command Prompt window on your PC and enter the command “ping 192.168.1.1”. If you do not get a response, then the problem could be one of the following:
•The IP address of the unit has been changed from its default of 192.168.1.1. Use the Digi TransPort Connection Wizard (which can be downloaded from the Support area at Digi.com or the Digi Device Discovery Tool). It can usually discover the unit on a network as long as the unit’s firewall has not been enabled.
•PC IP configuration. The PC’s LAN interface that is connected to the unit should be configured to “Obtain an IP address automatically”. If required, the Digi TransPort Connection Wizard can be used to configure the PC.
•Check the PC’s LAN connection and any LAN device (e.g. Ethernet switch) that is used to interconnect to the unit.
•Refresh the PC’s IP settings by opening a command window and enter “ipconfig /release” then “ipconfig /renew”.
•ARP resolution. Clear the PC’s ARP cache with the command “arp
5.3 Unable to log in to the Web Interface
Access to the unit can be achieved via any of the asynchronous serial ports. Connect your PC to the unit using a “straight through” RS232 serial cable. This will allow you to change the configuration via the Command Line Interface (CLI). Please refer to the Digi TransPort User Guide for information on how to use the CLI. The User Guide can be downloaded from the Digi Support site. If you have further questions about your product please contact Digi Technical Support (see page 2 for contact information).
