ABOUT THIS MANUAL This manual is intended as a reference guide for the Interactive Touchscreen running under Windows XP™ or Windows Vista™. This User Manual provides the information needed to set up the touchscreen. In addition, this manual describes basic technical information about the touchscreen and troubleshooting.
INTRODUCTION This manual will explain the workings and setup of the touchscreen fitted to your display. An explanation of the monitor and its workings is covered in the Monitor Manual that came with this product. The following pages will tell you how to install the software needed by the touchscreen to function and go through the adjustments that user’s can change to enable the screen to perform effectively in many different environments.
INSTALLATION LOADING THE TOUCH DRIVER SOFTWARE ONTO PC 1. Switch on monitor Do not plug the touchscreen interface cable into your computer. 2. Insert the ‘Information & Touch Software installation CD’ into the PC and follow the automatic installation instructions. If the installation does not start automatically; 1. Click START on the Windows™ Taskbar; then click RUN. 2. Type d:\Autorun.exe where d is the letter of your CD-ROM drive. Click OK 3. Select the ‘Touch software’ button from the on-screen menu.
STARTING THE DRIVER CONTROL PROGRAM Connect the touchscreen cable to a free serial port of the. 1. If the Touchscreen control panel is not already running, start the driver by clicking the icon on the desktop or select the Windows™ START button and RUN "Ma7_Control_En.exe" with the necessary path or double click Ma7_Control_En.exe from ‘Windows Explorer™’ or click the short cut placed on the desktop.
Fig 2 EXPLANATION OF THE STATUS SECTION 1. The following explanation of the Status section assumes that the touchscreen is physically attached to a serial port of the PC: Open - will go red and remain red only when the driver is present, the correct port is chosen and the Baud rate is set correctly. If the Open box does not go red then the driver is not loaded or another driver has taken the port.
The mouse pointer will not respond to a touch until it has been enabled in the Output section of the Control Program. Details of this will follow later in this manual. The Reset button loads fresh data from the touchscreen. This is used as a reference for detecting any new touches. This may be necessary if the touchscreen environment has been changed; for example, the touchscreen has been moved.
ADJUSTING THE TOUCH SENSITIVITY LEVEL Automatic Setup When you receive your unit, the sensitivity settings will have been optimised when the unit was manufactured. These settings should only be altered if you are experiencing problems such as an electrically noisy environment. Contact your supplier if you need further explanation. 1. To select the sensitivity setup click on the Sense tab. Fig 3 2. First set the Course Sensitivity to approximately two thirds by dragging the bar with your mouse. 3.
7. The moving indicator under Finger Pressure shows the strength of touchscreens signal. Nominally the Coarse Sensitivity slider is adjusted so the Finger Pressure indicator moves about a third of the way along in response to a light touch. 8. The Press Threshold slider is used to adjust the sensitivity of the touch to simulate a mouse button press. The driver recognises a touch when the Finger Pressure indicator exceeds the position of the Press Threshold slider.
CALIBRATION 1. Select the Calib tab as shown below (Fig 5), click the 'Start Calibration' box. Fig 5 2. You will see the following screen (Fig 6); there are three targets to touch in total, like the one shown below: Fig 6 3. When each of these targets is displayed, touch and hold your finger on the centre of the circular target. You must touch all three targets in turn. 4. The red circle in the target slowly moves towards the centre of the target. 5.
SETTING THE TOUCH OUTPUT TO SUIT THE APPLICATION PROGRAM 1. Select the Output tab. Fig 7 2. Select the mouse control required for your application (Fig 7). To enable the touch function on the screen, tick the Enable check box. 3. No action selects no mouse pointer movement or button pressing when touching the touchscreen. 4. Move mouse only enables mouse pointer movement but no button movement when touching the screen. 5.
You must now save the settings Fig 8 1. (Fig 8) Click on file. 2. Click on save to save the current settings. When the touchscreen driver has been set up and there is no requirement to change it.
DIAGNOSTICS AND FREQUENTLY ASKED QUESTIONS Testing the Hardware with ‘Graph’ 1. Select the Graph tab. Fig 9 2. Run a finger around the sensor, the effect of the finger on nearby wires can be seen by a visible movement on the indicators (Fig 9), each representing one wire. The algorithm in the driver interpolates the response curve to generate an accurate co-ordinate for the finger position. The following hardware checks can now be made: Wire Integrity Test 3.
MONITOR MODE Fig 10 1. This section is used to check the output of the touchscreen over the whole display area represented by the white box in the centre. It is useful in checking for any dead areas on the touchscreen and the performance of the touchscreen being able to follow the finger accurately and responsibly (Fig 10). 2. When using this feature make sure that the touchscreen output is disabled by un-ticking the Enable Selection Control in the output section.
USING EDGE ENHANCEMENT 1. To allow easy access to the sliders and buttons at the edge of the display, the cursor can be positioned nearer the edge of the screen. The amount of enhancement can be adjusted via the screen shown. Fig 13 2. Each of the sliders represents one edge of the sensor; the default position is as illustrated above (Fig 13). 3. Edge Gain can also be used to counteract the effects of nearby metalwork that surrounds the display area. 4.
FAULT FINDING GUIDE The following are some possible reasons why the touch screen might not work. If they do not solve your problem or you have a situation not covered please contact your supplier. DRIVER DOES NOT SEE THE TOUCHSCREEN Touchscreen on a different comm port than the one selected. The Baud rate is incorrect. Another device, driver or program is using the port.
There are several ways to improve system performance. Optimise the Background performance against the Applications, to do this follow the simple instructions below: Select the Windows™ START Button; go into Settings and Control Panel. Open the System folder and select the Advance tab. Press the Performance Options button. Change the selection from Optimise Performance for Applications to Optimise Performance for Background Services.
