23. 17 October 2008 12th CBM Collaboration Meeting -- Walter F.J. Müller, GSI 23 Design of the CBM readout chain 'Starter Kits' and '1 st round demonstrators' use existing or pre-prototype read-out ASIC's, prime objective is fast availability to support tests of concepts and building blocks. Key aspects for final CBM readout chain  scalability to full CBM detector size and data rates provide interface to FLES (First Level Event Selector)  adapt to radiation environment determine where COTS components can be used minimize functionality in exposed areas (on detector) put complex logic into unexposed or shielded areas
