Configuration File (config)

The configuration file config contains the startup informations about the readout configurations. It contains:

• directories the program is using to locate control block files, detector description files etc.,
• base address of the dsp
• and default detector planes connected to the dsp.

#
#      directories
#
dataDir:        data
detectorDir:    detectors
ctrlBlkDir:     cb
autoPilotDir:   autop
#
#   dsp address
#
dsp:  0x00080000
#
#   detector planes
#
link:  0  kek1_a
link:  1  kek1_b
#
#
#

The key words dataDir:, detectorDir:, ctrlBlkDir and autoPilotDir: specify the directory names the program searches to find files.

dsp: is the base address of the dsp. The dsp address has to be specified.

link: linkNr fileName tells the program that the detector plane with the detector description file fileName is connected to link linkNr.

Detector Description Files

A detector description file contains information about a detector plane. If a detector plane is added to the readout (using the Setup property page), the corresponding detector description file is executed. The following example lists all possible options.

chips: N

number of readout chips (CDP's). The total number of readout channels is 128 * N

counterVal: N

The counter value is the data size in bytes. If the value is not given the counter value is calculated from the number of chips. nChips = 3: counter_value = 54; nChips = 6: counter_value = 105;

loops: n

number of loops an fifo is executed using the doCalibrate command. The maximum number of loops is given by the memory of the dsp, the number of readout triggers within one execution of a control block and the data size (depends on the number of chips) from the detector plane.

calDelay: N

delay of the calibration pulse. N must be between 0 and 255. For most of the ll-cards the full range corresponds to a delay between 0ns and 75ns. The correct value for the delay is obtained by a delay scan measuring the efficiency versus delay.

hit_type: 0/1

The hit type specifies if a 0 or 1 is interpreted as a hit. For most of the newer detectors a 0 is the hit type.

V_ref, v_att, v_cal, v_thres: V

dac settings. v_thres is in [mV] all ohter values are in [V].

CB_cal: file N1 .... N4

Calibration control block file and the channels (modulo 4) the calibration pulse is seen.
CB_cal: cal_0.cb 1calibration signal is seen in the readout channels 1, 5, 9, ....
CB_cal: cal_0.cb 0 3 calibration signal is seen in the readout channels 0, 3, 4, 7, 8, 11, ......
