Troubleshooting tool for touch-screen devices with third-party digitizers

A number of touch-screen devices such as laptops or tablets which are not equipped with a Wacom digitizer can be configured to capture signatures by means of a special licence which allows Wacom signature software to handle Microsoft Pen Protocol, also known as RTS or Real-Time Stylus.

Wacom software still has difficulty with some touch-screen devices (such as later models of the Surface Pro) because they generate multiple virtual monitors or tablets and the software doesn't know which one to connect to for the pen data.

In order to assist in diagnosing such situations please download rtsInfo This is a combined console and window program for diagnosing RTS issues.

It lists all available virtual tablets and allows each one to be tested for pen response.

It should be ideally run from a command prompt but it is possible to run directly by double clicking on it from Explorer.

When run it will start with a console window, displaying a list of all the "tablets" (virtual monitors) installed, and then pop up a grey window.

As seen in the image above, count is 7, indicating that there are 7 virtual tablets or monitors.
rtsInfo displays all 7 virtual tablets (index range is 0-6), and then also displays the results of what the system regards as the "default tablet".

After that, the program uses (by default, see below) the first device that reports “DeviceKind: Pen”.

Carefully place your pen/cursor over the grey window – the text window will show pen data if the selected tablet is responding to the pen.

Ensure you have the console window as the focus window, then you can press ESC to quit.

When run from the command line (or Start->Run…) you can provide the index of which tablet to use. For example:

rtsinfo 4

This will override the automatic selection and use the tablet identified by the specific index.

Repeat the above, starting at 0 until the console window displays information when you pass over or press on the grey window with your stylus.

NOTE: beware of accidentally using the mouse in the console window to select text – while text is selected (even if it’s a single character) this will prevent the console window from responding and temporarily hang the program.

Once you have established the index number of the virtual tablet which responds to the pen then you can use it to populate a registry setting called "rtsIndex" - this will then be used by sign pro PDF or the Signature SDK when capturing signatures.

rtsIndex should be of type DWORD and should be created in the following registry key:

HKLM\SOFTWARE\Wow6432Node\Florentis\sd

Your registry key should then look like the highlighted entry in the screenshot below:
