Capture Process
UCD hardware blocks are described in the figure below. Simplified version of the capture
process is described as follows:
1. Set V-by-One color depth (6/8/10/12 bits /V-by-One byte mode)
2. Choose the desired number of V-by-One lanes to be captured.
3. Set color depth (8/16 bits) that is transferred over USB to PC. This setting affects data
amount i.e. preview frame rate. It does not need to be the same as V-by-One color
depth chosen in step 1.
4. Trigger capture start.
5. Video frames are saved to memory until memory is full.
6. Frames are readable one by one from the memory until memory is empty.
7. To continue, go back to step 4.

10
Device chaining
Two or more UCD-2s can be chained together for capturing more than 8 lanes. The
connection is done with a synchronizing cable as shown in the figure below. Figure in the
following page shows the intended V-by-One connections in a chained configuration.
When chaining devices, please pay attention to the following:
 Device chain must not form a ring.
 Both ends of the cables should always be connected to a device.
 All devices must be connected to the same computer via USB cables.
 LOCKn and HTPDn must be connected to correct devices for reliable operation.
 Please not that connecting the lanes incorrectly does not prevent capturing but will only
affect visible video.

11
External Trigger
An external trigger can be used to start video capture precisely at the right time. Connect
the external trigger to the Sync IN input (See Fig. 9). The trigger should provide a 3.3V
logical levels. Video capture can be started by either rising or falling edge.
The input is internally pulled up (10k resistor) to 3.3V. It enables triggering the video
capture manually with a push button that simply grounds the input.
External trigger mode needs to be enabled by setting the option value
UUCD_OPTION_EXT_TRIGGER to either EXT_TRIGGER_FALLING or
EXT_TRIGGER_RISING. Setting the option to EXT_TRIGGER_NONE disables external
trigger mode.
Exactly like in free-run mode, the application should invoke UUCD_StartCapture() and
then it can read frames by calling UUCD_GetFrame() until all the buffered frames are
transferred to a PC. In external trigger mode, the first UUCD_GetFrame() call may take
long time as it will be waiting for an external trigger to start video capture. Consider setting
long enough timeout by calling SetOption() with
UUCD_OPTION_FRAMEINFO_TIMEOUT parameter.
If UCD-2 devices are chained, the master device propagates the trigger to all slave devices.
All chained devices start video capture synchronously.

UCD VIEWER
Unigraf UCD Viewer software is the configuration and capture GUI for UCD-2 devices.
System requirements
The UCD Viewer application can be used in 32-bit and 64-bit editions of Windows XP,
Windows Vista, Windows 7, Windows 8 and Windows 10.
Installation
UCD Viewer can be installed by running UCD Setup.exe. The installer will allow you to
select the components used and configure the install locations.
Device and Mode Selection
When UCD Viewer is launched, you can first select the connected UCD device.
In the following dialog you can select the signal mode that you want to use.

13
Preview Window
When you click Start capture a window will open and show a preview of your captured
content.
You can align the size of the preview window to the content by right clicking on top of the
window and selecting one of the fixed zoom factors 25% [Alt+1], 50% [Alt+2] or
100% [Alt+3].
You can display the captured content in a borderless window by selecting Borderless
Mode. You can also maximize the window on your desktop by selecting Maximize.
Controls
You can end the current session by selecting File > Stop Capture.
You can select another capture device by selecting File > Close Device. From the dialog
click the new capture device that you need to use.
Saving
 By selecting File > Save snapshot (Ctrl+S) you can capture and save individual frames.
By selecting File > Save video sequence you can save a sequence of captured frames.
Capture Format
 You can select the capture image format from Tools > Options. The available formats are
PPM (up to 16 bpc), BMP and JPG (8 bpc).
In the same dialog you can also select the folder where the image files are stored.

UCD-2 Vx1
Vx1 Basic Video Capture Configuration
In the following window you can select the preferred Vx1 Capture Configuration settings.
Vx1 Capture Configuration settings are described in the figure below.

15
Setting Descripiton
Lane count
Number of lanes to capture. For cascaded devices, it shows the total number of lanes for all
devices.
Capture color depth
Selects input color
-
depth and capture color
-
depth. The preview display is always 24 bit true
-
color, while saved file will have the requested color-depth.
Section count Number of sections the frame is divided into.
Color mapping Selects color-mapping mode. (Vx1 should always use JEIDA).
Measurement Mode DE-only or Hsync-VSync based measurement
Vx1 Lane mapping
All zero means that default mapping is used (= No change of lane order). This feature can
be used to correct a situation where the Vx1 lanes are mixed up for some reason. For
example, if lanes 1 and 2 are reversed on the physical connector, enter 2 to the first edit
box, and 1 to the second.
External trigger Controls using external trigger mode, see 2.7
Capture mode
In real time mode, the internal UCD-2 device buffer memory is not used, it only stores one
frame. the screen is updated with minimal delay but some frames might be lost due to
limited USB2 band width. In the buffered mode, a sequence of frames is stored in the
internal buffer memory and then transferred to the PC. There are no frame gaps in this
sequence. There may be gaps between sequences.
Lock Options Adjust the needed delay period based on product specifications. For the configuration rules,
follow
the table
below
.
HTPDN
:
0 = Normal operation
(Default)
1 = HTPDn signal is
forced low
2 = HTPDn signal is
forced high
LOCKN
0 = Normal operation
(Default)
1 = LOCKn signal is
forced low
2 = LOCKn signal is
forced high
3= LOCKn signal is
forced low, and stays
low, after "LOCKN
delay" time has
elapsed. Timer starts
after HTPDn goes low
internally in normal
operation. Setting of
"HTPDN" value does
not affect this timer.
LOCKN delay, us:
Timer value in
micro seconds to
"LOCKN" option 3.
Default is 42000 us.
Video valid delay, us:
Timer value in micro
seconds after which valid
video is received from
source after LOCKn
signal goes low. Setting
"LOCKN" option 1 or 2
does not prevent timer
operation. Default is
42000 us.
After selecting the settings you can start the acquisition by pressing ‘Start Capture’
button. You can return to the configuration window by selecting “Stop Capture” from the
“File” option in the main menu. To return to the device selection window, select “Close
device” from the “File” option in the main menu.

16
When capture is in progress, single frame capture and frame-sequence capture features
are available through the “ File” option in the main menu. Captured frames are stored in
files according to the settings in “Tools” → “Options” dialog described in chapter 3.5.
Internal pattern generator
Settings are similar to those described in Vx1 Basic Video Capture Configuration.
Timing Measurement
In device operation mode, select Timing Measurement.

17
Settings are similar to those described in Vx1 Basic Video Capture Configuration.
UCD Viewer tabs
