Reconfigure the Touchscreen
The final step in adding a third serial port to your PowerStation is
to reconfigure then calibrate the touchscreen. You must do this
because the COM port for the touchscreen has now changed from
COM3 to COM4. You can calibrate the touchscreen in MS-DOS
mode by running the touchscreen configuration utility from the
MachineShop Shell. If you are running Windows on your Power-
Station, you can reconfigure the touchscreen by running the
UPDD program in Windows. If you use both MS-DOS and
Windows operating systems, you must reconfigure the touch-
screen in both DOS and Windows. Instructions for both proce-
dures follow.
Reconfiguring the Touchscreen under
MS-DOS
To reconfigure the touchscreen, complete the following steps:
1. Reboot the PowerStation, and when “Starting MS-DOS...” ap-
pears, press the F5 key on your keyboard.
2. At the DOS prompt, type
edit AUTOEXEC.BAT
.
3. In the AUTOEXEC.BAT file, change the Address and/or IRQ
setting, and save the file.
Note
The following segment of the AUTOEXEC.BAT file
shows the new values for IRQ and Address.
4. Reboot the PowerStation.
Important
You must restart your system for the changes to take effect.
The third serial port to your PowerStation has been successfully
installed. You can now use this port to communicate with external
devices.
