Nanovison Mimo touchscreen display configuration 30th May 10
As suppliers of the Mimo touch screen driver we are often contacted if any issues are encountered with the Windows touch driver supplied with the device or the Mac and Linux driver supplied directly from us. This is in part because there is little or no direct support offered by the manufacturers or suppliers of the device. We have no problem with assisting with Mimo touch queries but we have found by experience that many issues arise from either the supply of old out-of-date drivers or user misunderstanding of the use of our driver.
The Mimo device uses a resistive touch controller from a company called e2i which later became SJT. The graphics USB interface comes from a company called DisplayLink and latest drivers are available on the web site at http://www.displaylink.com/support/downloads.php. It is always recommended you download and install the latest graphics drivers along with the latest touch screen driver, see below
This document is mainly aimed at the Windows users but the same advice applies to the Mac OS X and Linux users. Touch-Base Mac and Linux drivers are not automatically supplied for this device but drivers are available from the download page of our web site or from links at the bottom of this document.
Regarding the touch driver, called UPDD, we initially supplied version 3.x.x of our Windows driver. This was superseded with 4.0.x and recently the suppliers were shipping 4.1.6. We are now shipping 4.1.8 for full Vista and Windows 7 touch utilisation – See note 1). Our driver is supplied in the form of an executable called setup.exe. A lot of Mimo users seem to be supplied version 4.0.3 or 4.0.6, 32 bit support only, which in the UPDD software names the touch device as “e2i Technologies, NTR, USB”. There are also some 4.1.x drivers using this name but when e2i became SJT we supplied a 4.1.6 driver for 32 and 64 bit in which the device is referred to as “SJT, USB”. Both these names refer to the same device. In addition, 4.1.6 automatically recognises when the device is rotated and adjusts the calibration accordingly.
From our records we believe that 4.0.x, depending on the build, may have some calibration issues. We also know that when these earlier versions are installed the Windows desktop associated with the touch device by default is the primary monitor, in UPDD terms this is called the ‘Whole Desktop” and therefore the calibration screen and mouse movements will occur on the primary monitor, not the Mimo device!
Given that the Mimo device is normally an extra monitor on a Windows system then the UPDD Console program needs to reflect the relationship between the touch device and the Windows monitor associated to the Mimo device. So, for example, if you attach a Mimo to a single monitor computer the Mimo device is likely to become Monitor 2, attached to a 2 monitor system it is likely to become Monitor 3 etc.
In this example a Mimo device is connected to a Single monitor system to create a dual monitor system whereby the Mimo device becomes Monitor 2. In this case the UPDD setting is as shown.
In the above example, when you run Calibrate the calibration screen will be displayed on the Mimo device and when you touch the screen the touch will also relate to Monitor 2.
Since UPDD 4.1.x the driver supplied to e2i/SJT tries to automatically make this desktop association (See note 2) once the Mimo touch device is detected so it is possible that the setting will be correct after install. If this is not the case then manually change the setting.
The latest 4.1.6 driver for the ‘SJT, USB’ device can be downloaded from here.
Supported Operating Systems:
Windows 7 ------------------------- (UPDD 4.1.6 does not invoke Windows 7 advanced touch features)
32 and 64 Bit Support
The latest 4.1.8 driver for the ‘SJT, USB’ device can be downloaded from here.
(http://touch-base.com/downloads/production/mimo/Win7/setup.exe). This supports the same OSes as above. Due to the current restrictions (Note 1) the extended touch option is disabled by default.
A full set of UPDD documentation is available on our web site at http://touch-base.com/documentation.asp, specifically:
Windows Install: http://touch-base.com/documentation/WindowsPlatformNotes.htm
UPDD Console: http://touch-base.com/documentation/UPDD%20console.htm
Windows 7 extended features: http://touch-base.com/documentation/OS%20Extended%20Touch%20Features.htm
We recommend that you use the latest graphics driver from DisplayLink and the latest UPDD driver.
With these drivers in place if the touch still fails to work, then, unless there is a hardware error with the touch hardware, it is likely that the system has not associated UPDD with the touch USB controller. To confirm this is the case open up the UPDD Console. In a working system the touch device name should be shown in black. This means that the driver is associated with the device. If the name is shown in red (e2i Technologies, NTR or SJT) or missing then the driver is not associated with the device, as shown here:
In this instance unplug and replug the USB device. If this does not correct the problem and the touch does still not work then run up the Windows Device Manager (Start > Control Panel > System > Hardware > Device Manager) and look for a device called USB Touchpanel. If this entry is missing the system is not physically seeing the device and there may be a hardware fault. If it is listed it will have a yellow exclamation mark to indicate the driver is missing.
Right click on the device and select the option to manually update the driver and follow the instructions, selecting the UPDD driver when prompted to select a driver. More information on this procedure is available here.
time or writing (May 2010) UPDD 4.1.8 with extended touch mode enabled the
touch input is directed to the primary monitor only. In normal touch mode the
touch input is directed to the assigned desktop, e.g. Monitor 2. To utilise extended touch features with the
mimo device set the device to be the primary
monitor. A future release of UPDD will remove this restriction and all UPDD
supported devices will be able to use extended touch features.
2) The driver searches internal structures looking for an attached video device with the characteristics of a Mimo device. This method is not 100% reliable. The Displaylink interface now offers an API to identify the associated monitor and in a future release of the driver we will be using this API.
Trial drivers for both Linux and Mac OSX are available for the Mimo device. Costs for production drivers are here.
