Tutorial 6. How to programme the Touch Screen ‘Soft’ buttons.
6.0
The touch screen requires an interface which connects the touch screen to the ‘AUX’ input of
the DVR. Contact Black Box AV for further information on this interface.
For the DVR, a ‘soft’ button is a rectangular area of screen which, if touched, will cause the DVR to
jump to a particular sequence. Each new sequence can contain up to 20 ‘soft’ buttons. A button is
created by defining the top-left and bottom-right corners and then assigning a sequence number to the
button.
The touch screen could be used with the screen acting as one big button where touching any part
would activate a new sequence, however, for the tutorial, we will define 2 ‘soft’ buttons.
6.1
Firstly ensure the touch screen interface is connected and the DVR is paused displaying the still
image that contains 2 ‘soft’ buttons. If you have not recorded a suitable image, then choose a still
having two distinct areas that could represent rectangular buttons.
6.2
The ‘soft’ buttons are usually programmed as the first steps in a sequence so select ‘New’
from the ‘File’ menu to create a new sequence.
6.3
Click on ‘New’ and select ‘TOUCH SCRN’ as the Device and ‘ADD BUT’ as the
command.
6.4
The ‘Touch Screen’ frame is displayed. This has a button ‘Touch On’ to turn on the
transmission of touch screen data to the computer. The frame also displays the current X,Y
coordinates and has 2 boxes which display the last touch coordinates for Top/Left and Bottom/Right..
Another box holds the sequence number for this button.
6.5
Click ‘Touch On’ to begin the transmission of data - notice the caption changes to ‘Touch
Off’. The X/Y coordinates should be displaying 63/63 - this is the value when the screen is not
touched.
Touch, and move your finger around the screen and you will see the coordinates change. Notice that
the coordinates go from about 05/60 (top/left) to about 60/05 (bottom/right) i.e. 1st coordinate (X)
goes from left to right, 2nd coordinate (Y) goes from bottom to top. Also notice that when the screen
is released, the last touch coordinate is saved in the ‘Top/Left’ box. This is how we define the corners
of the ‘soft’ button.
6.6.
Click on ‘Top/Left’ to enter this coordinate. Then touch the screen at the top/left corner of the
1st soft button. Remove the touch and ensure that the correct coordinate is entered in the ‘Top/Left’
box.
6.7.
Click on ‘Bot/Right’ to enter the next coordinate. Once again check that the coordinate has
entered correctly.
6.8
Now click on the box containing the sequence number and enter the sequence number you
want this button to select. Enter ‘01’ for this button. Hopefully, if you have completed tutorial 5 you
will have a sequence 01 loaded to test the button.
