When the application is executed, it will display watchdog information in the WATCH-
DOG INFORMATION group box. It displays max time-out, min time-out, and time-out
steps in milliseconds. For example, a 1~255 second watchdog will have 255000 max

of the watchdog as follows:

REFRESH button. After you click this button, the Time-out Countdown field will
