How does the RS232 Watchdog work?
The watchdog function may be enabled or disabled by configuring the controller’s settings. When enabled, the controller expects to receive at least one character every 5 seconds. The character can be part of a command, or may be a dummy character that causes no action. If not character is received, the controller will cause the motors to stop. The controller remains active and ready to execute the next command as soon as it arrives. This function is designed to place the robot is a safe (stop) position in case the microcontroller, or wireless modem attached to the controller, fails.
