7.5 Execute Multi-Device Acquisition
As a precaution, restart all Time Controllers before you run the multi-device acquisition.
The Time Controller calibration is altered when:
•
It loses its SYNC signal (either because the IN cable is disconnected or when the
Time Controller which provides the SYNC signal is turned off).
•
Its configuration is switched between an external SYNC to the internal SYNC.
•
At this point, the device needs to be restarted to calibrate itself properly again.
With an acquisition configuration file correctly prepared (see Section 7.4 – Set up the Acquisition
Configuration File), the Time Controller software and firmware updated as appropriate (see
Section 7.1
– Up-to-date Software), and the supporting scripts stored on the host computer (see
Section 7.2 – Supporting Scripts) it is now possible to perform multi-device acquisition using the
timestamp_acquisition_multi_tc.py script.
The acquisition is executed through the timestamp_acquisition_multi_tc.py script in a command line
interface. Open any command line console (such as cmd.exe) in the script
’s directory and run the
following command to print the available options, also detailed here below:
python3 timestamp_acquisition_multi_tc.py --help
or
py timestamp_acquisition_multi_tc.py --help
C:\Users\ < user> > cd C:\Users\ < multi-tc script dir>
C:\Users\ < multi-tc script dir> >py timestamp_acquisition_multi_tc.py --help
usage: timestamp_acquisition_multi_tc.py [-h] [--conf file] [--datalink-dir
path] [--output-dir path] [--duration seconds] [--log path] [-v] [-n N]
optional arguments:
-h, --help show this help message and exit
--conf file acquisition description file (default: config.json)
--datalink-dir path DataLinkTargetService.exe folder
--output-dir path output folder
--duration seconds acquisition duration (default: 5)
--log path log file (default: timestamp_acquisition_multi_tc.log)
-v, --verbose
-n N, --repeat N repeat measurements N times }
