In the tested NIS Elements version, some but not all of the settings shown in Figure 3 are correctly set and saved in the MS-2000. Check for this issue if the MS-2000 does not behave as expected. For example, if you check Reverse X and click Apply, then the box should still be checked after shutting down and restarting both NIS Elements and the MS-2000.
You can also make and save settings using the ASI Console software. However, some versions of NIS Elements override saved settings when connecting to MS-2000.
Note also that Reverse X and/or Reverse Y work correctly only in MS-2000 model WK2 version 8.8j and later.
