General Installation Instructions

To install this ePad System Software, Download the software from our website and follow the instructions to complete the installation of the ePad software.  

Silent or Unattended Installation

Installation can be automated by using response files. To generate a response file, run setup.exe on a typical target machine as follows:

** These commands should be typed into a command prompt window or the Windows Run dialog (accessible by clicking Start --> Run). Replace <full_path_to_setup> with the fully qualified path and file name where setup.exe is located (e.g., d:\setup.exe). Replace <full_path_to_response_file> with the fully qualified path and file name where the response file is to be created/read from (e.g., c:\response.in).

<full_path_to_setup> /r /f1"<full_path_to_response_file>"

Configure the installation as you want all targets to be configured. When setup completes successfully it will create the response file at the location specified.

To run the installer silently, issue the following command on the client machine(s) (this assumes you've copied setup.exe and the generated response file to the client):

<full_path_to_setup> /s /f1"<full_path_to_response_file>"


Terminal Server and Citrix Support

l   On Windows 2012 go to control panel, viewed by small icons, click on the “Install Application on Remote Desktop…” icon and follow the instructions on the wizard to install ePad Software. Make sure using the custom installation and check the Terminal Services Server on the Terminal Services page.

In the event you wish to manually enable support for Terminal Services, the following procedures can be used:

ePad provider names, folder names, and file names

Terminal Services may be manually configured for the following ePad products by using the file names designated:

Provider Name

Key Name

File Name

ePad USB



ePad-ink USB









Server Installation

  1. Install the ePad Software
  2. Create the following registry folder:

HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server\AddIns\<Key Name>

  1. Create the following keys / values within this new folder:

REG_SZ,Name,<File Name>

Client Installation

For the client, the Citrix/Terminal Services client software is required. Download and install the latest client software based on the client Windows type (32 or 64 bits).

Map Inking Region Only (ePad-ink)

This option will result in data only being reported within the specified inking region of the device. The data is rescaled so that unity is within this region. Note that no data reports will occur outside this region when this option is enabled.


ePad-vision Images

The ePad-vision has the ability to store up to ten screensaver images and one signature background image in its memory. These images can be managed via the ePad-vision Control Panel, which can be found in the Windows Control Panel. ePadLink recommends using images that are sized to 480 x 272 pixels to avoid distorting the images appearance on the device.


ePad-vision Downloadable Font

The ePad-vision has the ability to store up to twenty-five System Independent Format (SIF) fonts in its external memory (Flash or RAM). SIF fonts can be created using the FontGen.exe program located at the ePad/Tools/ePad-vision folder. These SIF fonts can be managed via the ePad-vision Control Panel, which can be found in the Windows Control Panel.  Please refer to the Local Font Manager User Manual at the Tools/ePad-vision folder for detailed instructions.


Known Issues

In firmware versions 1.00 and earlier contact with the touchscreen while performing I/O to the device (such as transferring a background image) may result in the device failing to respond over the USB bus. The end result is that device functionality will be lost. To recover:



If the computer is shut down or restarted while an application is using an ePad-ink unit, the display may not be cleared. The display should be refreshed the next time an application initializes it or it can be manually cleared by unplugging the unit and then plugging it back in.

On at least some HP / Compaq PC's we have observed that the process EAUSBKBD.EXE will open the ePad-ink preventing our system software from using our own pad. The solution to this is to:


The screensaver option fails when attempting to set it while initializing the pad. To change the default screensaver behavior, set the option after the pad has been initialized.

Since Windows 8.1, Microsoft has introduced a new power management method for USB devices to reduce power consumption on mobile computers. This approach may suspend the ePad device or show delay on signature capture. To solve this issue, the SetPowerManageField.exe, located in the ePadLink/ePad folder, may set the EnhancedPowerManagementEnabled field in the registry with proper value then reset the device to apply the changes made in registry.
