On selecting the ‘Disconnect’ button, the application will terminate the data exchange with the
equipment, the PC Com Port will be released and the window view will return to that which was
seen when the ET was first run showing the ‘Disconnected’ sub-window (see Figure 6).

ET main window which will now be blank. The ET application will then be terminated.
1.4.3 Accidental Disconnection
If the PC is physically disconnected from the equipment in error by unplugging the serial connector
while the ET is running, the ET will try to re-establish contact with the equipment for approximately
3 seconds. If the connection is restored within that time, the ET will continue as normal. If the
disconnection period exceeds that time, the ET will automatically invoke the disconnection
process. The ‘Disconnected’ sub-window will appear briefly stating ‘No response’ before returning
to the disconnected state.
1.5 R ETAINING S OLAR S ETTINGS
All of the NI parameter values and settings are held locally in the NI non-volatile memory as well as
being stored centrally in the TM. The only exception to this is the IP address which is only stored
within the NI itself and cannot be accessed remotely. Changes made to any NI “Engineering”
setting are automatically saved to both the NI and the TM irrespective of where the change is
initiated.
1.5.1 Engineering Mode
Before any engineering changes may be attempted, it is necessary to deliberately select the ‘Eng’
button, furthermore, any change will not be invoked until the ‘Apply’ button is pressed. Multiple
changes may be made and implemented together with a single ‘Apply’ action. Failure to apply a
change will result in the attempted change being abandoned and settings will revert to their
previous state when the corresponding ‘Eng’ button is released.
