You can determine which firmware was fitted when the Bus Coupler left the factory from the adhesive label underneath (see the fifth and sixth figures of the production number).

Example: 3200B2020000 - The firmware in the example is B2.

The KS2000 configuration software and the corresponding serial cable included with, is required for updating your firmware. You can also update your coupler using the System Manager from TwinCAT version 2.8 (in the case of the BK9000 only from firmware version B6).
