AOX files

AOX files containing channel parameters can be generated from the eDAQXR (not the eDAQXR-lite) Test control page while a test is running. An AOX file can include networked CPUs and connected channels. The AOX file may be viewed as text.

Test setup information shows at the top of the text file.

  • SetupFile: This is the name of the associated Test setup file, with the suffix .sxr.
  • RunNumber: This is the number appended to the particular test run from which the AOX file was generated while using the Test setup file.
  • NumXdcrChs: This is the number of channels in the test.

Channel descriptions show in a tab-delimited table in the text file.

  • ID: This is the CPU type, serial number, the layer and the channel connector number for a channel.
  • Units: This is the unit for the recorded values on a channel, for example, V, mV/V, °C etc.
  • NodeName: This repeats the ID but only for the CPU.
  • Connector: This repeats the ID but only for the connector, such as brg_2_c1, which is the number of the layer in a stack and the connector number on the layer for the channel.
  • Eng_FSMin: This is the engineering units full scale minimum for the channel. See Generic parameters Range min/max in Input channels.
  • Eng_FSMax: This is the engineering units full scale maximum for the channel. See Generic parameters Range min/max in Input channels.
  • Scale: This is the scaling factor or slope scaling parameter applied to a channel. See Slope in Input channel scaling parameters. In the AOX file, the scale is normally near 1. Changes from 1 in the Slope will only be visible as Scale in the AOX file if the Range min/max is also changed to allow a slope/scale greater than 1 to show.
  • Offset: This is the offset or intercept scaling parameter applied to a channel. See Intercept in Input channel scaling parameters. In the AOX file, the offset is normally near 0 (zero).
  • Volts_FSMin: This is the full scale voltage minimum for the channel.
  • Volts_FSMax: This is the full scale voltage maximum for the channel.
