What is the difference between Serial Number (S/N) and User Code (U/C)?

• S/N format is XX-XXXXX(X)

Serial Number (S/N) is a 7- or 8-digit number that represents the serial number of the station. S/N is always required when you ask for technical support at support@dataapex.com. S/N is saved in the HW key and is permanent (i.e. does not change with the Clarity configuration change). Last 5 or 6 digits extended most often by 40.000 correspond to the number written on the HW key itself. The prefix usually differentiates OEM versions, e.g. Clarity Offline has 98-xxxxx(x) number format.

• U/C format is X(X)-XXXXX-XXXXX-XXXXX

User Code (U/C) is a 16- or 17-digit (one- or two-letter prefix) code formed from letters and numbers that unlocks the specific Clarity configuration. It defines the version of SW and other specifications (e.g. bought extensions). User Code is always unique for the corresponding HW key and might be variable and changes whenever the customer purchases an additional instrument, control, extension or upgrade. When the configuration is changed you need to set the new U/C (given usually via email) in the Clarity main window - Help - User Code... dialog.
