DTU

Data encryption

The tablet driver sets up encryption on the USB data flowing from tablet to driver.
In the driver, the data is unencrypted and sent to the tablet inking service as any non-encrypted tablet would send such data.

Disable the mouse on the tablet but allow the use of the pen

Actual Multiple Monitors (http://www.actualtools.com/) (as recommended by DisplayLink who provide the video driver used by many of our business-oriented tablets) includes this feature.

Their Web site has a description of the feature. An evaluation version of the tool can be downloaded free of charge but a fee is payable for a permanent licence.

Please note that we cannot provide support for Actual Multiple Monitors or accept any liability for its use - please contact the company in question directly for any queries or support needs.

Move an application directly to the DTU without having to drag it using the mouse

From Windows 7 onwards you can use keyboard shortcuts to move windows from one screen to another:

  • Win+Shift+Right-arrow - moves current window to the screen on the right
  • Win+Shift+Left-arrow - moves current window to the screen on the left

There are a number of third-party applications which offer this functionality by means of hot keys or a single mouse-click on an icon.

For example:

  1. Actual Multiple Monitors
  2. Ultramon

Please note that we cannot provide support for Ultramon or Actual Multiple Monitors or accept any liability for their use - in all cases please contact the companies in question directly.

If your primary requirement is to open a PDF on a DTU then both sign pro PDF and Adobe provides this feature as explained in this Microsoft article

Please see also our FAQ on capturing signatures with dual monitors

Open a specific Web site directly on the tablet

The following online articles may be of help:

Alternative solutions we could suggest:

  1. Use of a hot-key to move a window directly to another monitor without having to drag it with the mouse, as provided in Actual Multiple Monitors
  2. Ultramon which allows you to run automated scripts - see for example LaunchApp at https://www.realtimesoft.com/ultramon/scripts/

Prevent the Windows taskbar from appearing on the tablet

The DTU acts as an extension or duplicate of the Windows desktop and functions in the same way as a second monitor.

This means that it can be treated in the same way as a second monitor when it comes to managing various aspects of the Windows desktop.

Windows 7

On Windows 7 the taskbar is not normally displayed on a secondary monitor configured to act as a desktop extension.

Third-party software is required if you want one to display one - there are various applications available on-line including Actual Multiple Monitors which is recommended by DisplayLink.

Windows 8

Switch the tablet on and off programmatically

In order to enable or disable the DTU display (switch it temporarily on or off) one possibility is to use DisplaySwitch.

Further details on its use can be found on winaero.com

For example it could be activated via a batch file containing the command "displayswitch /internal" or "displayswitch /extend" with a desktop shortcut linked to it.
It could then easily be run on demand from the user's login session.

Alternatively you may find that similar functionality is available in a third party tool such as the following:

Find the display number of the tablet to use in the wtCintiq registry setting

  1. Download and install EnumDisplayDevices
  2. Download and install EnumDisplayMonitors
  3. If needed run EnumDisplayMonitors from a command prompt to see a short list of display device IDs (see example 1 below)
  4. Run EnumDisplayDevices from a command prompt and look for a display ID which is marked as "ATTACHED_TO_DESKTOP" (see example 2 below)
  5. Use the appropriate display number for the wtCintiq registry entry, e.g. \\.\DISPLAY3

Example 1

   lpRect {0,0 1920,1080}
      rcMonitor = {   0,   0 1920,1080}
      rcWork    = {   0,   0 1920,1040}
      dwFlags   = 0x00000001 [MONITORINFOF_PRIMARY]
      szDevice  = \\.\DISPLAY1  

    lpRect {1920,0 3840,1080}
      rcMonitor = {1920,   0 3840,1080}
      rcWork    = {1920,   0 3840,1040}
      dwFlags   = 0x00000000 []
      szDevice  = \\.\DISPLAY2  

   lpRect {3840,0 4864,600}
      rcMonitor = {3840,   0 4864, 600}
      rcWork    = {3840,   0 4864, 560}
      dwFlags   = 0x00000000 []
      szDevice  = \\.\DISPLAY3

Example 2

    Name:   \\.\DISPLAY3
    String: Intel(R) HD Graphics
    Flags:  00000001 [ATTACHED_TO_DESKTOP]
    ID:     'PCI\VEN_8086DEV_016A\SUBSYS_1790103CREV_09'
    Key:    '\Registry\Machine\System\CurrentControlSet\Control\Video\{43767078-F844-4E74-9C90-E499C4F8E9B7}\0002'

    Number: 0
    Name:   \\.\DISPLAY3\Monitor0
    String: Generic PnP Monitor
    Flags:  00000003 [ATTACHED_TO_DESKTOP MULTI_DRIVER]
    ID:     'MONITOR\WAC1045\{4d36e96e-e325-11ce-bfc1-08002be10318}\0001'
    Key:    '\Registry\Machine\System\CurrentControlSet\Control\Class\{4d36e96e-e325-11ce-bfc1-08002be10318}\0001'

Write an application to capture a signature on the tablet

The quickest way to write a signature capture application for a DTU tablet is to use the Signature SDK - see under "For signature".

Handling tablets with the Signature SDK

The Signature SDK is a general purpose high-level SDK which displays a signature capture window with a standard design and format on a signature capture pen device.
As such it is compatible with almost all Wacom pen devices including DTUs and STUs.
It does not provide any functionality within the API which is specific to DTUs because it is designed to provide a general purpose user interface which is adjusted automatically within the SDK to suit the current signing device.

Please note that the wizard control functionality will not work with a DTU as it is much more effective to use standard Windows forms programming techniques.

Low-level SDK programming for Wacom tablets

The DTU tablets are programmed using Wintab - the DLL which accepts the Wintab API is installed as part of the Wacom tablet driver.
There is no need to download any separate SDK - everything is included in the tablet driver itself.

Further information on Wintab is available on our Wacom Developer Relations Web site

All technical queries regarding use of the Wintab SDK should be raised via a Support Ticket.

Wacom tablets and the Signature SDK wizard control

The Wizard control is for use with STU pads only.

It allows the user to be guided through a set of instruction pages displayed on the LCD display, each page requiring a selection by tapping the pen on the pad surface, for example by selecting a radio button then selecting <Next>.

When using a Wacom signature display such as a DTU-1031 (which acts as an extension of the Windows desktop), similar functionality can be achieved using a standard Windows application.

Why won't the STU SDK work with my DTU/DTH/DTK tablet?

The STU SDK can only be used with STU pads. As at time of writing (July 2018) these are the STU 300, 430, 500, 520, 530, 540 and 541.
It is available on the following platforms:

  • Windows 7 SP1 or higher
  • Linux
  • MAC OS 10

Please note that there is no browser support on Linux or MAC OSX.
For details about the low-level API for DTU devices please see the Wacom Device Kit.

Obtain the serial number of a DTU

Via Device Manager

The serial number of a DTU should normally be displayed in the 'Device instance path' of the properties window in Device Manager. It should look something like this:

USB\VID_056A&PID_0336\5AZQS00085

Via Wintab

Using Wintab the serial number can be obtained from the device context.

For example, in the ScribbleDemo code-sample add the following call to the beginning of the OpenTabletContexts function.
 

char uniqueTabletID[32] = { 0 };
int numBytes = gpWTInfoA(WTI_DEVICES, DVC_PNPID, uniqueTabletID);

 
This populates uniqueTabletID with the serial number of device 0.
If there are multiple Wacom devices on the system (or the user preferences have information for multiple devices, having had different ones plugged in in the past), then it may be necessary to get the serial number of device 1, or device 2, etc.
This can be done as follows:
 

int deviceNumber = 0; // Place device number here
char uniqueTabletID[32] = { 0 };
int numBytes = gpWTInfoA(WTI_DEVICES + deviceNumber, DVC_PNPID, uniqueTabletID);

 

It can always be guaranteed that the DTU-1141 attached to a system is device 0 if only the DTU-1141 is attached to the system, no other Wacom devices.
Alternatively it can be achieved by either of the following:

    • Clear user preferences (this is destructive and will remove user settings)
    • Stop the Wacom Professional Service
    • Remove contents of C:\Users[USERNAME]\AppData\Roaming\WTablet
    • Start Wacom Professional Service
       

  2. Execute the following command at a command prompt:

C:\Program Files\Tablet\Wacom\32\PrefUtil.exe /remove-all

 

NB: in recent driver versions, PrefUtil.exe is located in C:\Program Files\Tablet\Wacom\PrefUtil.exe

Please note that the service takes a few seconds to fully start up, depending on the machine.

Why does my DTU only work as a mouse over RDP?

The standard Remote Desktop tool which comes with Windows is not able to handle pen data.
If you want to use a DTU or other Wacom pen input device successfully over RDP a third-party USB redirection app is required.

We collaborated with a company called Incentives Pro to ensure that our DTU pen displays worked well with their Terminal Services USB-Redirection software. This was in a Windows-based environment at both ends, i.e. client and server.

If you have a different requirement such as a Linux-based client then please contact Incentives Pro directly to see if they can support you.
