• All the components above the serial hub (device specific below) are generic standard plug-ins.
• Device specific readout system is designed to be modular (equal vertical slices) and easily expandable. This allows developing software, testing and commissioning of the detector much simpler.
• Use of commercially available hardware (serial hub, Aligent DAU, ethernet hub, router/gateway, etc…)
• Data path in the low level should be protected from the outside network traffic, however, the DAQ operation system must be easily accessible.

• Operating System: Linux• Language: c with gnu compiler • network protocol: TCPIP• DCS interface: DIM socket connection• rawdata: input to COCOA for the fast alignment
reconstruction of chambers.• Rawdata Exchange:
• Most of the rawdata are totally internal to the EMU system and no need for data exchange between the subsystems. Only a very small amount of MAB DCOPS sensor rawdata for the barrel system are possibly being read out by the EMU DAQ.

• Basic DAQ design is finished and tested• We have, currently, a set of necessary hardware elements
to test/develop a modular and expandable DAQ system.
• Router/Gateway (1)
• Rocketport Serial Hub (2)
• Agilent DAU (2)
• DCOPS readout electronics (multiple number of DSP cards, Interface cards).
• We have made and successfully tested a simple C program to readout both DCOPS and Agilent DAU. It works under Linux OS using a setup with all the basic readout hardware components listed above.
We have been using above setup to test/debug our FE.
Near Future Plans for DAQ Near Future Plans for DAQ Near Future Plans for DAQ Near Future Plans for DAQ
1. Continue to develop the DAQ software to add more functionalities.
2. Modify RS232 to RS422 readout at the serial hub (at a moment, using RS232).
3. We need to look into more on: making sure this DAQ configuration works with the nominal cms operating conditions, such as magnetic field and radiation.
4. Get ready for the 2004 magnet test. (see more on next page)

• Should be able to read out the full EMU alignment system using the hardware and software components for EMU DAQ described above.
• Some of the ‘nice’ functionalities of DAQ (GUI, DCS connections, Database access, etc.) may not be ready, yet. But that should be ok for this test.
• The software must be developed enough that during the magnet test we can have fast feed-back from the data taken. This means that the interface between raw data and COCOA, and COCOA software must be well established enough that we can get fast feed-back from COCOA output (results of muon alignment reconstruction).
