Before you can use credentials of up to 240 bits with your Mercury controllers, you must enable support for long credentials on your Synergis™ unit.

Before you begin

Ensure the following:
  • Your Synergis™ unit is running Synergis™ Softwire 11.0 or later, and that it is online and connected to your network.
  • The Mercury controllers you want to use long credential support with are running firmware version 1.29.1 or later.

What you should know

Because credentials of 64 bits or longer are not automatically synchronized with Mercury, you must manually enable them.


  1. Log on to the Synergis™ unit.
  2. Click Configuration > Mercury controller settings.
  3. Expand the Database layout settings section, and select the Long credentials database layout from the list.
  4. Expand the Long credential formats section, and enter the credential length you want to use.
    The value must be from 64 to 240.
  5. Click Add.
    You can add up to eight different credential formats.
  6. Click Save.
  7. Restart Synergis™ Softwire on your Synergis™ unit:
    1. In the top menu, click Restart > Software restart.
  8. After Synergis™ Softwire has restarted, log back on to the unit.
  9. On the Mercury controller settings page, expand the Buses section.
  10. Click Reset for the controllers that require long credential support.


The new credential formats you enabled can be used with your Mercury controllers.
