Note:
Logoff GUI mode
After working in administrator mode through the PC GUI, you can choose to log-off (File,
Logoff). This sends a disconnect command to the board (see
GUI window. Remove the RS232 serial cable.
All three LEDs glow for 4-5 seconds (see
Figure 18. Logoff message
The system then becomes available to operate in user or administrator modes through the
board itself (see
Automatic Logoff from GUI mode (through watchdog)
The system is designed in such a way to support automatic log-off from GUI mode, if no
communication from PC is received.
No communication from the PC could be due to:
●
●
In this situation the system watchdog is activated for approximately 30 seconds. After that
the system resets, all the three LEDs start glowing for 4-5 seconds (see
system then becomes available to operate in user or administrator modes through the board
itself (see
As this is a case of improper log-off, it is desirable that when the serial communication is re-
established between the PC and board the user should re-login to view the real status.
Otherwise the status on the GUI may not be updated.
Shortcut: By directly closing the GUI window, a disconnect command is directly issued
to the board. Remove the RS232 serial cable.
RS232 cable un-plugged without proper log-off from the GUI
GUI idle for long time, no serial communication between PC and board
