This is the simplest mechanism for using the stand-alone programmable SmartKeys dongles, i.e. models PR, EP, SP

and XM. It enables automatic verification, on all the system's ports, of the presence of a protection dongle with Label,

Password and Secure Data assigned, to find out if the dongle is present and on which door.

COMPARING mode is therefore an extension of the LOCATING MODE, valid for programmable dongles only. It can

be useful in programs where verification of dongle presence is sufficient, without the need to update the contents by

means of Secure Data rewriting operations.

The exchange of information is organized like this:

values, the status variable will have a value of 1,2 or 3 at the end of the operation, according to the LPT.

9.12 Model reading mode

The MODEL READING function enables one to identify the installed SmartKey model (FX, PR, EP, SP, XM, NET).

This is an accessory function, which, for example, can be used to activate a different type of behavior for software

packages operating in both standalone and network versions.
