cadett ELSA is protected from unauthorised use with a so-called hardware lock.
Regardless of the number of available licenses, cadett ELSA can be installed legally without any reservations on an unlimited number of workstations. It is however forbidden to use the program on more computers at the same time than there are available licenses.
Hardware locks is one of the methods that are available to enforce the compliance of the above stated rules. There are two types, as described in the table below.
Type of lock |
Description |
|---|---|
Local hardware lock |
Local hardware locks always contain one single license per lock. The hardware lock is connected to the workstation where the license is to be used. If you want to move the license to another computer, you simply move the hardware lock to that computer.
The hardware lock is connected to a USB port of the computer.
|
Network hardware lock |
This type of hardware lock is connected to a server, usually but not necessarily the same server where cadett ELSA is installed, and does always contain more than one license. The licenses do not have to be for the same product. It can be a mixture of different cadett ELSA products.
The lock itself is connected to a USB port of the server.
A license calculator on the server makes sure that no more than the maximum available licenses in the hardware lock are running in the network at the same time.
Two programs are installed on the server for this management. One of them is a driver for communication with the physical lock. (The same type of driver that is used on the workstations when using local hardware locks). The other is a service that controls the communication with the workstations and contains the license calculator mentioned above.

Regardless of the selected hardware solution, the lock (or locks) will give access to the specific number of licenses and license types you have purchased. The locks are therefore unique and dependent on the selection of available products you have bought.
•If you for instance have a lock for cadett ELSA LT, you cannot use the functions that only exist in cadett ELSA Professional.
The simple logic is that you can always use a simpler solution than you have purchased, but never a more advanced.
The cadett ELSA licenses are always “floating”, regardless of whether you have selected a local lock or a network based lock. This means that you can move licenses between computers as desired. The technical management of this varies however. A local lock must be moved physically. For a network lock, the only action needed to move a license from one workstation to another, is to shut down cadett ELSA on one computer and then start the software on another. This is of course more convenient in a network, but has the drawback of not allowing the software to be used without a network connection (for instance on a stand-alone laptop).
You can freely mix the different lock types in the same cadett ELSA installation, and have some licenses in a network lock and some in local locks. This is often the optimal compromise, benefiting from both solutions at the same time.
Worth mentioning, and sometimes important to note is that the selection of hardware lock solution is completely independent of the type of installation of cadett ELSA. The software can be installed either locally or as a network installation. Regardless of the installation type, you can freely select between local hardware locks and network locks, and vice versa. All combinations are possible.
Another important note is that the hardware locks are to a large extent backwards compatible with older versions of cadett ELSA. The current hardware locks can therefore be used all the way back to cadett ELSA 7.0, which was released in 2002.
