How to Reprogram the Touch Screen controller with MicroCal

1. Download the MCAL.ZIP microcal software to your C:\TNS directory.
2. Get to a DOS prompt in the C:\TNS directory.
3. Unzip the software on your computer by typing PKUNZIP MCAL from your C:\TNS prompt. The software will then be in your TNS directory along with all the other InfoTouch files.
4. At the C:\TNS prompt, type MICROCAL to start the program. Then press the SPACE bar to get the main menu screen.
5. Use the UP/DOWN arrow keys to highlight DIAGNOSTICS; press <ENTER>.
6. Highlight FIND TOUCH SCREEN; press <ENTER>.
7. Highlight SERIAL; press <ENTER>. If it finds the touch screen, it will beep and display information on the right side of the screen in the STATUS window. Write down what it says for PORT, BAUD and PARAMETERS.
8. Throughout the next few steps, you'll periodically see a red warning screen that reminds you that you're changing settings. Ignore the warning screens because that's exactly what you want to do. Get back to the main MicroCal screen.
9. Highlight CALIBRATION and press <ENTER>. Touch the crosshairs as they appear on the screen.
10. Highlight CONFIGURE and press <ENTER>. Select Sensitivity, set it to high if there's a lot of humidity in the air, normal if humidity is very low.
11. Highlight Data Protocol, then SELECT protocol, and choose HEX STREAM.
12. Highlight AUTO BAUD DETECTION ENABLE and press <ENTER>, select DISABLE.
13. Highlight COMMUNICATION PARAMETERS and press <ENTER>
14. Select N,7,2 and press <ENTER>
15. Then highlight selections to EXIT and continue to exit the program. You should be back at the C:\TNS prompt.
16. Type CD\ and press <ENTER> to get to the C:\ prompt
17. Now you should be able to restart your system. If it still does not work properly, you may have to calibrate the touch screen from InfoTouch as well: click here: InfoTouch Calibration
