ADBG Menu Item (Auto Debug)
This menu item has the same function as the DEBG menu
item. The only difference is that the functions are executed
automatically.
After selecting this menu item, an attempt is made to start up
the bus. If startup was possible without any errors, data and
ID cycles will start after a waiting time of 1 second.
The LED diagnostic indicators on the devices enable you to
determine to what extent the bus is started up. If all BA LEDs
are active, the bus is running without errors.
As soon as a bus error occurs, an attempt is made to restart
the bus after a waiting time of 1 second. This is repeated until
startup is successful.
The display reading corresponds to that of the DEBG menu
item.
