Associating AIM reader commands with terms allows changing term value on corresponding command from the reader.

The commands are executed in the Card and PIN reader mode only. In other modes, commands are not executed (see 1 in the figure below). Most of the reader commands are only supported by the AP-500 reader. The usual reader with a keyboard support PIN+10 and PIN+20 commands (2 and 3 commands, correspondingly).

To enter a command using AP-500 reader, swipe a card, then press Cmd, enter a command number and press <Enter>. The even command sets corresponding term to TRUE, the odd command sets it to FALSE.

Correspondingly, when PIN+10 is entered, the term associated with 2 and 3 commands will be set to TRUE, when PIN+20 is entered, it will be set to FALSE.

PIN+10 and PIN+20 means that 10 or 20 is added to the PIN number, correspondingly. For example, if a user has PIN code 8080, then PIN+10 = 8090. The user will have to enter 8090 to set corresponding term to TRUE.

Assigning AIM reader commands with terms is performed as follows:

1. Go to the settings panel of the Apollo AIM Reader object.
   
2. Click the IV Settings button (2).
3. The Connection with variables configuration dialog box opens.
   
4. In the drop-down list in the Internal variable column, select the Apollo Internal Variable object corresponding to the variable the term of which the command from the reader should change (1).
5. In the IV term drop-down list, select the Apollo Term object corresponding to the required internal variable (2).
6. Click the OK button (3).
7. Click the Apply button (3).
8. To save the changes to the controller, write configuration to hardware.
