2. Tracker DAQ with EPICS
By the last week, DAQ using DATE with EPICS has been checked to work correctly by the following procedures.
Installation of DATE package
Write test code
Rebuild trigger logic
Take data of C1-4 counters with DATE
Check data
Take data of C1-4 and 8 VLSBs
Check data with that taken by EXCEL
Replace code of AFE with EPICS one

3. R8 cosmic-ray test stand
In R8, cosmic-ray test for Tracker#1 is running, and Tracker DAQ has been tested this time.

7. Notes on v6.28 Few codes were needed to fix to start readout process.
Path to readout exe. file is changed as below.

9. Responsibility of DATE and EPICS in Tracker DAQ
Readout data from VLSB
Enable/Disable trigger of VLSB
Clear VLSB buffer
EPICS
Configure AFEIIt boards
Enable/Disable trigger of AFE
Read temp./heater values of cassette

11. Embedding EPICS code in DATE
EPICS - wrapped with C++
DATE - written by C
Compile equipmentList file by g++, then linked with other DATE object files to make readout exe. file.
~10 lines in “infoLogger.h” were changed as below.
- extern void infoLog  extern “C” void inforLog
#ifdef __cplusplus
#endif __cplusplus

12. Start run ArmAFE() 1. Check if AFEIIt boards are configured
If no, run stop, and
User configures boards using EPICS ConfigurationUI.
2. Enabling trigger of AFE boards by EPICS

14. Data taking
Latest run(#323) is currently taking data, now it has 2k events.
Trigger rate is about Hz (1 event/min)

15. Decoding There 3 equipments to record data
V792N: ADC of trigger counters (4 channels)
AFE: Temp/Heater of 4 cassettes (32 channels)
VLSBSlave: ADC/TDC of 8 VLSBs (4096 channels)
