== Introduction ==
STIX uses dynamic time binning onboard to ensure that onboard storage and telemetry is not wasted by having time bins that only have background counts. This scheme relies on 3 parameters:
* Minimum integration time
* Maximum integration time
* Maximum counts per bin.
As STIX accumulated counts, the time bin is closed IF:
* The minimum integration time is exceeded
AND
* Maximum integration time OR maximum counts is reached.
Once a time bin is closed, a new one is started automatically and counts continue to be accumulated.

To customise this scheme therefore, we need to alter these parameters in the ASW (onboard application software).

== Procedure ==
Once Starlet has been open and an IOR or PDOR has been set up, do the following:
* Change STIX into Configuration mode. Be sure to truncate the calibration run if switching from Nominal mode.
* Click "Add Sequence" and select command sequence AIXF414A Load ASW Parameter v02. This enables you to change an application software parameter. In the pop-up window that appears set the following parameters:
** Parameter ID = 312 (minimum integration time) or 313 (maximum integration time) or 314 (maximum counts)
** Parameter subID = 0. This means you are changing the value of the parameters rather the min and max allowed values which have different subprocess numbers.
** Integration times are given in units of 0.1s - 1. For example, 1s == 9 (1s / 0.1s - 1)
* Change back to Nominal Mode.
