Software Licensing

A software activation license is necessary for major new upgrades of Maestro and ATCS firmware.
There is a substantial amount of work that goes into each major upgrade and this effort needs to be
supported through nominal license fees.  This will assure that further future upgrades and continued support are
available for ATCS.

ATCS: New features this release

AtPark cleared with alignment
-----------------------------
Changed ATCS behaviour so that the AtPark flag is cleared with alignment (even if there is no movement).  This is to ease compliance
with the ASCOM Telescope v.3 standard Unpark() method.

ATCS: Bug fixes this release

Hang after some period of time operating
----------------------------------------
Version 4.00.000 will hang after a period of time varying between power-up and several hours after power-up. This has been fixed in version 4.00.001.
