Chapter 4 Using the Microcal Diagnostic Utility 89
Finding the Touchscreen
When you open Microcal, Microcal automatically searches the
communication ports and tries to find a touchscreen.
Microcal also has a Find Touchscreen option. If Microcal has already
found the touchscreen, you do not need to use this option. However,
you can press F6 to reset the touchscreen and its controller to an initial
state. In this case, the Status box displays the message:
Search not activated
You must then select the Find Touchscreen option. If you select
another option before finding the touchscreen, the system displays a
message that you must first find the touchscreen.
To find the touchscreen, select Find Touchscreen.
(Depending on the type of touchscreen controller connected to your
system, you may need to select Diagnostics from the Main menu, and
then select Find Touchscreen.)
When you select the Find Touchscreen option, Microcal
Scans the communication ports and mouse port for a touchscreen;
and searches the valid combinations of communication ports, baud
rates, and parameters to enable communication with the controller.
Tries to communicate with the touchscreen controller.
Requests information on the touchscreen and its controller.
Waits for the touchscreen controller to respond.
If Microcal finds the touchscreen, the Status box displays the current
operating parameters. The information displayed includes the current
communication parameters (parity, stop bits, data bits), the hardware
version, and the firmware version. You can now select other options.
If Microcal does not find the touchscreen, the Status box reports that
Microcal failed to find the touchscreen. Check that the touchscreen is
connected properly, and then repeat the search.
