CSC DAQ Test System

The system includes one DDU (Device Dependent Unit),  one DAQMB (DAQ Mother Board), one or several CFEB (Cathode Front-End Board), one FTC (Fake Trigger Card), and one JTAG driver.  The following connection instructions applies to DAQMB pcb version 2, and CFEB pcb version 2.

The DDU is plugged into a computer PCI slot, DAQMB may be plugged in VME crate or just +5V power supply, The CFEB needs +5V power supply for digital part and +6V for BUCKEYE amplifier (if +6V is not available, the digital +5V can be used by setting a jumper on CFEB), the FTC needs +5V power supply, the JTAG driver needs +9V power supply.

Cable connections between the boards:
1. One two-way optical fiber between  DDU and DAQMB;
2. One 50-pin round shielded cable for control signals and one 14-pin skew clear cable for channel link between each CFEB and DAQMB;
3. Three  26-pin flat cables, one for fake ALCT data, one for fake CLCT data, one for fake TMB data, and one 20-pin flat cable for fake CCB data between DAQMB and FTC;
4. One 25-pin flat cable between computer parallel port and JTAG driver, and one 14-pin flat cable for LVDS JTAG signal between JTAG driver and DAQMB;
5. Six 34-pin cables between each CFEB and the chamber;
6. One BNC cable (TTL level) for LCT, and one BNC cable (TTL level) for L1ACC to FTC, if the signals are available;
7.1. If CCB is available, connect the 20-pin flat cable between DAQMB and CCB, instead of FTC;
7.2. If CLCT is available, connect the 26-pin flat cable between DAQMB and CLCT, instead of FTC, and connect one 26-pin skew clear cable between CFEB and CLCT.
7.3. If ALCT is available, connect the 26-pin flat cable between DAQMB and ALCT, instead of FTC;
7.4. If TMB is available, connect the 26-pin flat cable between DAQMB and TMB, instead of FTC.

Jumpers and Switches on the boards:
DDU: Set switch on the front panel to 'FIBER';
DAQMB: Set J5, J6, J7 to match the available CFEBs;
FTC: set S1, S2 switch according to LCT and L1ACC signal source;
Set all other switches and jumpers on the boards to default position.

For a more detailed cable connections, switches and jumper setting, refer to CFEB setting, DAQMB setting and FTC setting respectively.

Software setting:
Modify the configure files at ~fast/data/daqmb_config/daqmb_config_000X to match the hardware, available CFEBs, FPGA programming files, and programmable delay setting etc.

On power-up:
manually reset the FTC FPGA, and run the 'FULL SETUP' in CFEB_CONTROL to load DAQMB, CFEB FPGA program files and other settings.  If the DAQMB is powered off, set DDU switch to LOOPEN to avoid overheat of GLINK chips.
