Appendix B
Advanced Script Language (ASL)
The Advanced Script Language (ASL) is an extension of the Upper Level Protocol
Decodes that allows you to define custom upper level protocol decodes in addition to
those provided with the product.
The ASL, as defined, enables the user to extract and interpret arbitrary data from the
UWB stream by creating custom scripts.
The ASL protocol decodes may be used to decode any class or vendor-specific
requests and descriptors, protocols or any structured data transferred over the USB
bus, or can be used to complement pre-defined protocols.
This appendix is the essential reference for ASL users including definitions, code
snippets, and complete examples. The decode script files can be written in any text
editor or using the Catalyst script editor and must be saved with an *.asl file extension.
