Functional Description
UCD-422 units consist of a multimedia signal input stage, an internal pattern generator, a
control stage with on-board frame buffer and a PC interface stage. In the Input Stage the
signal is conditioned and converted to desired format. The Interface and Control stages are
either passing the captured data directly to the USB interface or storing it to the frame
buffer. The internal pattern generator is able to source a signal for testing sink and branch
units. The Interface & Control stages are receiving instructions from the host PC to
configure and control the functionality of the unit.

LICENSE MANAGER
Licensing
The features of UCD Console GUI are divided into groups based on the target use of the
device. Some basic features can be used without licenses. Advanced feature groups have
their dedicated licenses that open the related part of the GUI or enable the related control.
Unigraf licenses are provided as strings of characters, License Keys. Each License Key
enables a dedicated function in one device. Each device has its dedicated Seed Number.
Each License Key is tied to one Seed Number. License Keys can be freely used in any
number of PCs.
License keys are managed with Unigraf License Manager. By default, shortcut to Unigraf
License Manager can be found in Start Menu under: All programs/Unigraf/UCD-400.
Please click Yes in the first dialog. License Manager can be run only with Administrator
rights.
Note: System administrator's privileges are required for accessing the licenses.
License Manager GUI
When run, License Manager will list the licensing enabled Unigraf devices. If no suitable
device families are detected, License Manager will exit. Please first select one of the
available device families by clicking one of the device family selector buttons.
In the list of Attached Devices please select the device in question. The serial number and
the seed number of your device are printed in a sticker attached to the bottom of the device.
