2. Laptop pluggable for Debug, dedicated software including test features
Introduction
Simple test DAQ for prototypes :
FPGA for local Readout, simple USB interface, basic test software : Make Debug on Electronics & Detector
Need for single slab / standalone DAQ :
Laptop pluggable for Debug, dedicated software including test features

4. Timing Start on working mi April : 1 Month for first analysis
Needed yet : 1 week for code & 2 for vhdl
First boards back from manufacturers
1 Month for first analysis
Start working on next version in parallel at this point

5. Next Step Thinking to a 70cm x 70cm prototype
Slab based, ~10000 channels
Separated board for Readout
First step towards DIF for DHCAL
Hope to collaborate with UK DAQ groups on interface with LDA to be compatible with
Hope to participate in Testbeam at Fermilab
If so, need soon dedicated Concentrator card

6. Cubic meter module
Need to demonstrate reliability of physics principle project to build 1m3 prototype
(in fact only 70x70x100) ~ Channels
Will to be EUDET like as much as possible
Hope to be integrated in UK DAQ chain
At current developments state we project to achieve this current 2009

7. Conclusion Very tight schedule
First having the readout on this board working
Sharing experience should be interesting for all parties involved
Need to start quickly with mechanical consideration for interfaces to be defined
