Development Kits Identification Codes
The development kits (XELK, XUELK, BELK, etc.) are identified by a couple of codes. These codes are printed on a label sticked to the box containing the kit.
For example, the following picture shows such a label of an Axel Ultra XELK (XELK-H-S).
These codes are required to complete the registration process of the kit.
