Setting up OptiFDTD License Access

Optiwave tools use the Sentinel Software as a Service (SaaS) Pass utility to manage access to session-based shared license keys. To access a session license key for your OptiFDTD session, you must configure this utility so that your computer knows where to locate the key.

To configure the SaaS utility:

  1. Using a browser, navigate to the Sentinel Admin Control Center at http://localhost:1947/_int_/config_to.html.
  2. Click the tab Access to Remote License Managers.
  3. Check the box Allow Access to Remote Licenses, as shown in Figure 3.
  4. In the pane Remote License Search Parameters, enter the server name, as shown in Figure 3.

    Note: Always check CADpass Licensing Information for the latest server name.

Figure 3: Configuring a Remote License Key

  1. Click the button Submit.

Once the address for the OptiFDTD license key for your computer is correctly set and submitted, you can close your browser. Your computer does not need to be connected to the Sentinel utility during your OptiFDTD session. However, you may choose to leave the browser open so that you can monitor your access to a CMC session license key as required later in the procedure.

Note: You do not need to repeat steps 1-5 above, for subsequent OptiFDTD sessions.

Since the Sentinel utility may be used to manage concurrent software licenses for multiple CAD tools on your computer, you may be required to input several license keys into the remote license manager window. Contact for further details.

  1. Start CADpass client by clicking the icon CADpass on your desktop and double click the Optiwave checkbox, as shown in Figure 1.
  2. From your desktop, go to Start | OptiFDTD xx, where xx is the version number, as shown in Figure 4, and then select the program from within this suite that you want to use.
