This Astrometric Telescope Control System (ATCS) upgrade is for the PrimeTCS-Ui ATCS controller.

The minimum Maestro4 version which works with this version of ATCS firmware is 0.09.000. Assure that Maestro4 is upgraded to at least this version before upgrading PrimeTCS-Ui firmware.

Installation instructions

1. Assure PrimeTCS-Ui that the controller is attached via USB to the Windows PC.
2. Using the Device Manager on the Windows PC, determine the COM port number for the PrimeTCS-Ui controller connection.
3. Run the ATCS_FirmwareM_NN_RRR.exe file where N is major version, NN is minor version and RRR is revision.
4. The "Astrometric Firmware Upgrader" will run. Follow the steps in the user interface. Step #1 will be pre-completed for you. Step #2 is to select the COM port number for the attached controller and click "Connect". Finally, step #3 is to click "Upgrade Firmware". The upgrade will commence and status on progress will be provided.
   
5. Power-cycle PrimeTCS-Ui and it should now boot into using the new firmware and connect to Maestro.

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

- Added or updated support for the following ATCL commands in PrimeTCS-U
	- HGam	GetMAC_Address: returns the 48-bit network MAC address in hexadecimal format
	- HGsd	GetSkyWalkerDeviceSignature: returns the 32-bit device signature in hexadecimal format
	- HGsn	GetSkyWalkerSerialNumber: returns the device serial number
	- HGpx	GetAxEncFW_Ver: returns the firmware version of the AxialEncoder processors

ATCS: Bug fixes this release

- Field derotation for AltAz telescopes would not update the Position Angle provided to RotatorProU.
- TCS devices (e.g., HPJ, RotatorProU, FocusProU) would show presence (from Maestro's View --> Common --> System Information dialog) but
	when removed they would continue to show as present instead of showing as absent.
- The PrimeTCS-U Stat LED would power-up in the "there is Com" state (for a few seconds) even if there is no Com.
- Fixed various Static Status Change Notification problems including redundant PGrp and PGrt (refraction pressure and temperature) and lack
	of SSCN firing for TCS peripherals being removed.
