Fig. 6-6: Configuring a new board

All boards you can registrate are listed on the left. Select the wished board. (The
corresponding line is highlighted).
On the right you can read technical information about the board(s).
Activate with „OK“; You come back to the former screen.

Clear:

You can delete the registration of a board. Select the board to be deleted and
click on „Clear“.

Set:

Sets the parametered board configuration. The configuration should be set before
you save it.

Cancel:

Reactivates the former parameters of the saved configuration.

Default:

Sets the standard parameters of the board.

More information:

You can change the board specific parameters like the identifier string, the COM
number, the operating mode of a communication board, etc...
If your board does not support these information, you cannot activate this button.

Save:

Saves the parameters and registrates the board.

Restore:

Reactivates the last saved parameters and registration.

Test registration:

Controls if there is a conflict between the board and other devices.
A message indicates the parameter which has generated the conflict. If there is no
conflict, „OK“ is displayed.

Deinstall registration:

Deinstalls the registrations of all board listed in the table.

Print registration:

Prints the registration parameter on your standard printer.

Quit:

Quits the ADDIREG program.
