The Jinf communicates with the various slow control boards through a LeCroy bus. Commands can be directly sent to a selected bus, or the Jinf can execute macro commands to determine the status of all slow control boards: so-called AMSWire "sub-detector specific" commands have been implemented to perform checks and readout of all the slow control devices with simple calls.

AMS Tracker slow control

The Jinf communicates with the various slow control boards through a LeCroy bus. Commands can be directly sent to a selected bus, or the Jinf can execute macro commands to determine the status of all slow control boards: so-called AMSWire "sub-detector specific" commands have been implemented to perform checks and readout of all the slow control devices with simple calls.

  • 2E14 1001: Read the slow-control state, compare with pre-defined values, and give the list of discrepancies. The output format is as follows:
Word # Content
0 Provided by mainframe
1 Provided by mainframe
2 Provided by mainframe
3 Actel mask
4 Number n of discrepancies
5 Discr. #1 (var. name)
6 Discr. #1 (var. content)
... ...
4+(2n-1) Discr. #n (var. name)
4+2n Discr. #n (var. content)

For the discrepancies, the variable content is the actual setting, the one seen by the Jinf when reading out the slow control devices.

  • 2E14 1012: After having executed a 2E14 1001 command, you can also get the list of currents and voltages read out from the Jinf: 2E14 1012. Please note that the output will have a valid meaning only if you have previously executed a 2E14 1001 command. The output format is as follows:

Word #

Sorted ascending
Content

... ...
0 Error word 1 of TBS 5
1 Voltage of LR0 Hot, TBS 5
16 Current of channel 11, TBS 5
17 Error word 1 of TBS 15
18 Voltage of LR0 Hot, TBS 15
2 Voltage of LR0 Cold, TBS 5
3 Voltage of LR1 Hot, TBS 5
33 Current of channel 11, TBS 5
4 Voltage of LR1 Cold, TBS 5
5 Current of channel 0, TBS 5

The ADC to voltage and current value is done as follows:

  1. Voltage conversion (in V): V=2+(ADC-270.4)/41.45
  2. Current conversion (in uA): I=(a - 0.0735*ADC) constant 'a' is actually specific to every ADC channel. The following link gives you the parameter list.
