Figure 3-9. After Setting Up the Host Watchdog
Figure 3-9 shows that the user can read the status and the setting value of Host Watchdog. The
user got these values:
• 0:Host is OK,
• 1:Host Watchdog is Enabled,
• Host Watchdog time interval is 5 seconds.
Figure 3-10. Host Watchdog Demo.
After 5 seconds, the system displays a message that the “Host is down!!!” (Figure 3-10).
Click the button “OK” to close this message box.
Since the Host Watchdog is enabled, if the Host PC does not send the command ~** to module,
the module ignores all other output commands and the module output stays in the safe state
(Figure 3-11).
After the module goes to the safe state, the module’s Host Watchdog is disabled automatically.
Click on the button “Clear [Host failure mode]” to clear this status (see Figure 3-11). The module
status will return to “0:Host is OK!”.
