User Field:
Enter the name of the LDAP database field which contains the user names. Commonly used field names are
“uid” or “cn”, depending on the LDAP database in use.
Anonymous Bind:
This checkbox determines whether bind requests are sent with user name and password (more suitable for
Microsoft Active Directory), or if bind requests are sent anonymously (more suitable for Linux LDAP).
Firmware Upgrade
The UL2-DVI firmware can be upgraded over the network using a web browser. Prior to sending the firmware
over the network, the unit must be placed in upgrade mode. There are two ways to accomplish this, as follows.
The first method is to click the Upgrade Firmware button in the Advanced Unit Configuration Screen, which
causes the unit to close all connections and enter firmware upgrade mode. This method does not require
physical access to the unit. When the Upgrade Firmware button is clicked, the unit displays a Firmware
Upgrade Information Screen as displayed below. Click OK in the screen to proceed with the firmware upgrade
as described below.

The second method is by using the DIP Switches on the side of the unit. Record the IP address of the UL2-DVI
and remove power from the unit. Move DIP Switch 2 to the ON position. When power is reapplied to the unit, it
will enter maintenance mode, and firmware upgrade can be performed. This method can be used if the
firmware on the unit has become corrupted and there is no access from a VNC Viewer connection.
Once the unit is in upgrade mode, use a standard web browser (not a VNC Viewer) to connect to it by entering
the unit’s IP address in browser’s web address pane. The Perform Upgrade Web Page will be displayed.
