3.2 Network configuration of ADT-8840 
The user can activate the window of serial-interface software and press any key to enter the 
interface of configuration within 30 seconds after ADT-8840 is started, as shown in Figure 2. Two 
commands for configuration mode appear in Figure 2. Format of command input and how to send: 
enter the command by starting with the character “:” and the character string prompted in the 
interface (see Figure 2). Then click Send to complete the process. 
If the user has not input the command within 30 seconds, the system will automatically close the 
configuration mode so as to prevent the control card from unexpectedly entering the test mode, a 
situation caused by the serial interface interference. When the system closes the test/configuration 
mode, if the user needs to access the test/configuration mode again, the control card should be 
electrified again after powered-off. 
Figure 2 shows the two commands used for test/configuration.
