Description:

 Set Host Watchdog Timeout Value

 

Syntax: 

~AA3EVV[CHK](cr) 

~      delimiter character 

AA    address of setting/response module(00 to FF) 

3        command for set host watchdog timeout value 

E    1=Enable/0=Disable host watchdog 

VV    timeout value, from 01 to FF, each for 0.1 second 

Response: 

Valid command:       

!AA 

Invalid command:     

?AA 

 

Example: 

Command : ~010                  Receive : !0100 

Read address 01 modules status, return host watchdog 

timeout status is clear. 

Command : ~013164               Receive : !01 

Set address 01 host watchdog timeout value 10.0 seconds 

and enable host watchdog, return success. 

Command : ~012                  Receive : !01164 

Read address 01 host watchdog timeout value, return that 

host watchdog is enabled, and time interval is 10.0 seconds. 

Command : ~**                   No response 

Reset the host watchdog timer. 

Wait for about 10 seconds and don't send command~**, the 

LED of module will go to flash. The flash LED indicates the 

host watchdog timeout status is set. 

Command : ~010                  Receive : !0104
