SRTD-FLT Configuration Files

The SRTD-FLT configuration file is read via a symbolic link from:

/zeus/transputer/online/vxx.y/bin/host/hwconfig/srtd_flt.zeus

for physics runs and from

/zeus/transputer/online/vxx.y/bin/host/hwconfig/srtd_flt.qinj

for other runs.

The actual files can be found in directory $\:\tilde{}$calec_rc/defaults/hwconf. A tool is available to create these configuration files (refer to the SRTD-FLT experts...).

An SRTD-FLT configuration file contains 5 structures: 4 for each sector and 1 for the EVB/FLT-Card. Each sector structure consists of 3 structures for the sector's 3 Trigger Cards. Each Trigger Card structure has 80 bytes of data. The EVB/FLT-Card structure has 272 bytes of data.

The Trigger Card structure is as follows:

$\underline{{\bf Byte}}$		 $\underline{{\bf Contents}}$		 $\underline{{\bf Remarks}}$ 


0-3 		 address 		 card's VME-address 


4-51 		 threshold chan 0-23 		 bits 0-7=low, 8-15=high 


52-53 		 enable chan 0-15 		 bitpattern for 16 channels 


54-55 		 enable chan 16-23 		 bitpattern for 16 channels 


56-67 		 delays 		 6-bit delays, stored on byte boundaries 


68-69 		 status 		 for status register 


70-75 		 fifo 		 for FIFO control registers 


76-79 		 pad bytes 		 

The EVB/FLT-Card structure is as follows:

$\underline{{\bf Byte}}$ $\underline{{\bf Contents}}$ $\underline{{\bf Remarks}}$ 


0-3 		 address 		 card's VME-address 


4-5 		 offsets 		 for offset registers 


6-15 		 control 		 EVB/FLT control signals 


16-143 		 linear chan 0-63 		 timing lookup tables sectors 0,1


144-271 		 linear chan 0-63 		 timing lookup tables sectors 2,3

And the full structure of card configurations:
