- IMPROVEMENT - Added a button to copy and save the mount's current latitude/longitude to the current Site.

V5.10.00 - 2017-Jul-06  Release

Note: This is the minimum required version for APCC v1.6 and later.

- BUG FIX - Increase RA/Dec/Alt/Az precision (only) for GTOCP4-equipped mounts with P01-04 or later firmware.  Mounts with GTOCP3 cannot use high-precision commands because input commands to the GTOCP3 are limited to 16 characters or less.

V5.09.08 - 2017-Jan-31  Release

- BUG FIX - Park status was not always reported correctly.

 

V5.09.07 - 2017-Jan-23  Release

 

- BUG FIX -  if APCC sequence numbers get out of sync, a the response to a possibly different command could be wrongly get used. Fixed by clearing the response string when the sequence number is incorrect, so the response cannot be used. Also, cleared the internal send/receive buffers to empty all older sequence number responses. The following commands should then have the correct sequence number..

V5.09.06 - 2017-Jan-19  Private Beta

- IMPROVEMENT - the Time Zone offset in the user interface now reflects the generally accepted time zone polarity instead of the value returned from the mount.

V5.09.05 - 2017-Jan-01  Private Beta

V5.09.02 - 2016-Oct-31  Beta

- IMPROVEMENT - the controller type is now shown in the main window (slight user interface changes).
- IMPROVEMENT - If the controller is a GTOCP4 then hide the backlash setting controls, since backlash is not used.
- IMPROVEMENT - When connected to APCC, the "keep time synced" feature is now delegated to APCC. If APCC has its own "keep time sync" feature enabled, it will override the same setting in the driver. If APCC has "keep time synced" disabled then the driver will be able to override APCC and enable "keep time sync" until the next time that APCC is run.
- BUG FIX - Time Zones less than -12 were not being handled correctly.
- BUG FIX - Getting ASCOM DeclinationRate no longer throws an exception when tracking is disabled.
- BUG FIX - AP1100 was missing from mount types.
- BUG FIX - Fixed several ASCOM Conformance bugs when running driver through APCC.
 
- EXPERIMENTAL - When used with APCC 1.5.0.15 and later, the driver will now use a different COM port for the user and administrator accounts, allowing two instances of the driver to connect simultaneously to APCC. This will allow a mix of applications running under the user account and "as administrator" to connect to the mount through APCC.

V5.09.01 - 2016-July-19  Release

- BUG FIX - GetAllValues was pulling entries from the old AP.INI .file instead of Settings.apdb (this is a fix for proper operation with APCC).

- IMPROVEMENT - Improved robustness of the driver starting APCC and auto-configuring the COM port.
- IMPROVEMENT - Improved robustness of the driver opening the correct APCC virtual port.
- BUG FIX - Site latitude/longitude was not matching the mount if leading zeros were not used. The driver now autoformats the latitude and longitude with leading zeros if needed.
- BUG FIX - Under certain circumstances when parking from a counterweight up position the driver was not able to stop the initial slew to a counterweight down position, resulting in a potential equipment collision.
- BUG FIX - Force Meridian Delay to 0 before unparking (Rev S or later).

V5.08.09 - 2016-May-22  Release

-  BUG FIX -  Throw error immediately if COM port does not exist.

V5.08.08 - 2016-April-24  Release

-  BUG FIX  - Time synchronization was not working.

V5.08.05 - 2016-February-06  Beta

-  BUG FIX -  RA/DEC Bookmarks were not being displayed  if no previous bookmarks were set in the AP.INI when moving settings to the new database settings storage.
-  BUG FIX -  In the setup window the site settings values  could get out of sync with the database if values were changed but not saved. The driver now will now not allow the settings window to close until site settings have been saved or canceled.
-  The driver defaults have been changed to now show the driver when an application connects.

V5.08.04 - 2016-January-18  Beta

-  BUG FIX - GTOCP4 mount type was not defined properly and this ultimately caused an Error 380 in the setup window.

V5.08.03 - 2016-January-17  Beta

-  BUG FIX - in the driver setup window, when entering a decimal site latitude or longitude value, if the decimal value had all zeros (e,g "28.00") the minutes and seconds fields would not get filled in. Also a carriage return was not being accepted to force the conversion from decimal to hours, minutes, and seconds.

V5.08.02 - 2015-December-29  Beta

-  Installer - Changed installation location to a sub-directory under Telescope (e.g. "C:\Program Files\Common Files\ASCOM\Telescope\Astro-Physics")

- Started digitally signing the driver, each executable application, and the installer for greater security.

V5.08.01 - 2015-December-22  Beta

-  Changed order of text in a few controls to Latitude/Longitude instead of Longitude/latitude.

V5.08.00 - 2015-November-23  Beta

- SIGNIFICANT CHANGE -> Settings now saved to local shared (with APCC) database file (Settings.apdb)  instead of AP.INI. Old settings will be automatically copied to the new database ("settings.apdb") the first time the driver runs.

-  Site configuration now uses a single drop down list box for site names.

-  Sites are now common between APCC and the driver.

-  RA/Dec and Alt/Az Bookmarks are now saved and shared with APCC.

-  Eliminated "Send Longitude/Latitude to Mount" buttons because this can cause the mount to be unexpectedly re-oriented.

-  IMPROVEMENT - Added Site name to Virtual Hand box window. It will be highlighted if the site's lat/long coordinates do not match the mount's. Clicking the site name will open the driver page up to view the difference.

-  BUG FIX - Longitude/Latitude can no longer be changed after the mount has been initialized. If set from the ASCOM driver the changes will take effect the next fiull initialization.

-  BUG FIX - retical brightness was not being saved.

-  BUG FIX - Some settings were saved multiple times needlessly.

V5.07.02 - 2015-October-31  Release

-  BUG FIX - Safe Slewing did not operate correctly always when parking the mount.

-  Added option to not show the Park 1 warning any more.

V5.07.01 - 2015-August-30  Beta

-  BUG FIX - When decimal and comma are swapped because of regional settings the driver was sometimes passing improperly formatted commands to APCC.

V5.07.00 - 2015-August-08  Beta

-  BUG FIX - After a slew completes set to Sidereal so driver does not set tracking rate to custom rates.  This was causing the driver to send custom rates to APCC by accident.

V5.06.05 - 2015-April-25  Release

- Replaced "Allow connect when mount not present" with a timeout value in seconds. The new field is in the Advanced page of the driver's Initial Setup dialog window. A value of "0"  is an infinite timeout. Values from 1-600 seconds are also accepted. When a timeout occurs during an ASCOM Client's connect attempt control is returned to the ASCOM client application. Previously, if the "Allow connect when mount not present" was enabled, control might not ever be returned to the driver if the mount is not connected.

- Added a new variable "SafeSlewRaDec" that can be used in AP.INI. The default if it is not present is that Safe Slews are enabled (SafeSlewRaDec=1). To disable  safe slews set SafeSlewRaDec=0 in AP.INI.

- On connecting to the mount the driver will now query the mount type and if  a fork mount only do raw RA/Dec slews (no safety slews even if "SafeSlewRaDec=0" in AP.INI.

- Updated Windows version checking (in top of log files) to properly display the Windows version through Windows 10

V5.06.04 - 2015-March-25  Release

- Added a variable to enable old button down behavior found in 5.05.16 and earlier drivers, which while being more responsive might not register button up or down events when using remote desktop-like software..

This option is off  by default. Add this line to AP.INI to enable it:

   UseOldButtonBehavior=1

- Improved "Allow connection when mount not present". If not enabled and the COM port not present or mount does not respond the driver will report failure to connect. If present the driver keeps trying to connect.

V5.06.03 - 2015-March-13  Release

- BUG FIX - Tracking sometimes stopped when connected in 05.06.02.
- ENHANCEMENT - ASCOM driver call to DoesRefraction call now reflects APCC's refraction enabled check box.

V5.06.02 - 2015-January-16  Release

- BUG FIX - Throw exception immediately if COM Port not available

V5.06.01 - 2014-December-30  Release

- BUG FIX - Custom RA/Dec rates was always being set after a slew completed.

V5.06.00 - 2014-October-05  Release

- Validate range of custom rate to -99.9999x to 99.9999x sidereal.
-  Adjusted Park 4 location.

V5.05.41 - 2014-September-27  BETA

- Prevent use of Tracking via PulseGuide if mount has a GTOCP3 controller.
- Stop popping up unpark dialog whenever user clicks "Don't Unpark"  when mount is unintialized.

V5.05.40 - 2014-August-18  BETA

- Change behavior of AbortSlew() so that TheSkyX's jog buttons work correctly. When releasing a button SkyX calls AbortSlew() but technically a "slew" is a move to a specific RA/Dec or Alt/Az coordinates, not a move of unspecified duration as is the case when the user presses a move button in SkyX. This change will send a command to return the mount to sidereal if a slew was not in progress. The case where a slew actually is in progress is much more complicated and  behavior is not (and doesn't need to be) unchanged.

V5.05.39 - 2014-August-14  BETA

- Bug Fix - when using the driver through APCC sometimes the slewing active flag was not being set quickly enough causing fast polling ASCOM applications to think the slew was done even though it had only just started.

V5.05.38 - 2014-July-20  BETA

- Added extra checking for detecting power loss and making sure initialization occurs after power is restored.

V5.05.37 - 2014-July-12  BETA

- Bug fix -- after power cycle the driver was not initializing the mount when it should.
- Added new option in the driver's advanced settings to allow MoveAxis compatibility with most ASCOM clients. That is when the option is NOT checked (the default) and an ASCOM client sets the RA MoveAxis rate to 0 tracking will be returned to sidereal rate instead of stopped. Checking the option (NOT th e default) will produce the old behavior where RA MoveAxis = 0 stops RA tracking.

V5.05.36 - 2014-July-11  BETA

- Fixed mixed up flashing text when slewing.
- Made sure Latitude/Longitude are in order.
- Add item link to driver's start menu items for Release Notes Notes (this document).

V5.05.35 - 2014-July-10  BETA

- When "Allow connect if mount isn't present" is checked in the AP driver's advanced settings the driver will, when initially connecting to the mount, continually try checking for a connection at 200 msec intervals.

V5.05.34 - 2014-June-27  BETA

- Changed initial serial port receive timeout from 150ms back to value read from settings file.

V5.05.33 - 2014-June-23  BETA

- Improved  robustness when driver needs to start APCC. Sometimes a second instance of APCC would start.
- Improved power-loss/restart handling of commands. Sometimes the commands were sent out of order and the mount could lose position.
- Added a new property to the driver, ReceiveTimeoutMS, that allows  a client to change the read timeout.
- Fixed the max command retry count, which wasn't actually being used.
- Set initial serial timeout to 150 msecs. After connection is still gets set to the value read from the settings file.

V5.05.32 - 2014-May-05  BETA

-  When parked through APCC sometimes the Park request would not seem to complete.

V5.05.31 - 2014-February-03  BETA

-  If Synchronization to APCC is lost, when re-established, re-query APCC for various mount information.
-  "Pause logging when parked" sometimes shut off logging too soon.
-  Use LST from mount instead of calculating it when firmware is Rev S or later.

V5.05.30 - 2014-January-25  BETA

-  When parking the ASCOM driver sometimes returned control to an ASCOM client before parking was complete.

V5.05.29 - 2014-January-25  BETA

-  When slewing through APCC  the driver did not always indicate slew was active.

V5.05.28 - 2014-January-25  BETA

-  Removed the command that was turning off APCC's pointing and tracking correction when parking the mount.

V5.05.27 - 2014-January-20  BETA

-  To keep log file from growing automatically pause logging while parked for 3+ minutes.
-  Slightly redefined Park 1, 2, and 4 Park Positions.
-  Counterweight up park now handled by driver when used with APCC (requires APCC 0.99.99.54 or later)

V5.05.26 - 2014-January-9  BETA

-------------------------------------------------------------------

-  New Brightness command needs to accept a "1" response.

V5.05.25 - 2014-January-6  BETA

-  Fixed Unpark 4.

V5.05.24 - 2013-December-22  BETA

-  Restored the option to use Park 1 but with a warning message if you select it.
- IMPORTANT: please confirm that your park and unpark positions are still correct as this version reorganized the order of the park positions. To check, open the driver's Telescope Setup. and confirm your settings.
- Made improvements to the RAW command processing of the SetParkPosition, SetUnparkPosition. In addition to passing an index into the list to use you can specify the name of the park position(e.g,CommandString("RAW,SetParkPosition,Park 4", True)). A warning message will not pop up if Park 1 is selected in this way.

V5.05.23 - 2013-December-15  BETA

-  Added new option in the Telescope Setup on the Advanced page, "Other Options" group box. This option, which is enabled by default, will force a N/S/E/W calibration immediately before the first time a slew is done whenever the driver is run. The calibration takes less than a second so it should not cause any noticeable slowdown in telescope operations.
-  Added a new script command "AutoCalibrateNSEW", to allow a script or application perform the N/S/E/W calibration.
-  ApJog: Added a "Calibrate N/S/E/W" button to ApJog to allow manual N/S/E/W calibration.

NOTE: the Calibrate N/S/E/W routine is not needed when using APCC. In fact, it may not reliably calculate direction because APCC caches RA/Dec values., which are critical for determining direction.

V5.05.22 - 2013-December-11  BETA

-  The Swap N/S and Swap E/W buttons now will have a yellow background if  Rev U or later firmware is installed and the corresponding direction is reversed. IMPORTANT: If RA or Dec movements are reversed via the Swap N/S  orSwap E/W this will cause some autoguider calibration routines to fail, when autoguiding through the driver. Each button will show a tool tip warning message when its background is yellow.

If you are running an earlier firmware version than "U" (released December 2013)  and experience runaway guiding in RA or Dec you should click the appropriate swap button (Swap N/S or Swap E/W corresponding to the problematic axis) and follow your software's Autoguider recalibration procedure. This should make autoguiding to work correctly.

V5.05.21 - 2013-December-7  BETA

-  Added "Cancel" button to bookmark Alt/Az and RA/Dec goto's. Rebuilt APSetup.exe with .Net (it was built in VB6) to allow it to run as a regular user. Also added check boxes to installer to optionally install desktop icons for the utility programs installed by the driver.

V5.05.20 - 2013-November-13  BETA

-  Indicate that the driver is configured to use APCC by appending "(APCC)" after the COM port in the Mount Information control frame.

V5.05.19 - 2013-November-10  BETA

- When Rev U or later is installed use new reticle brightness command instead of sending a stream of B+ and B- commands.

V5.05.18 - 2013-September-27  BETA

- Fixed  Setup Wrong Slew Speeds for 1200 and 3600
- Clicking RA/Dec fields will immediately stop a slew or park instead of popping up a dialog asking the user to confirm.

V5.05.17 - 2013-September-22  BETA

- Expanded processing of version string returned from the control boxes.
- Improved internal abort slew implementation.
- When APCC is present commands for slew and park are now passed to APCC  to be handled by APCC instead of the driver. This behavior can be overridden by setting ApccHandlesSlews=0 in AP.INI.
-  Button presses were purposely ignored when the driver was in a timer. Changed behavior so that those button preses are no longer ignored. This affected the Part, Unpark, Set Alt/Az Park, Slew To RA, Slew To Dec,  Swap N/S, and Swap E/W buttons.
- Attempted to make the move buttons operate more robustly for those with wireless mice. This safety comes at a cost of the move buttons not always being as responsive as before.
- When a button move is active the appropriate RA and Dec field on the hand box will highlight.
- Removed multiple attempts to reslew to parked position.

V5.05.16 - 2013-August-17 BETA

- IMPORTANT change for PARK and UNPARK Operations: Replaced Park 1 with Park 4, which places the scope on the East side of the mount instead of the West side. This was done because when the mount started tracking from Park 1 and the user waited too long (maybe about 10 minutes) the mount could end up with the counterweight higher than the scope. When initialed in that position the scope would dive underneath the mount if commands to slew to a visible  object in the sky.

V5.05.15 - 2013-July-21 BETA

- "Admin"  will appear in the ASCOM logo when the user is running "As Administrator". Admin status also gets logged in the log file.
- Added new option in the Advanced settings to auto-enable tracking when ASCOM clients send certain commands with tracking disabled (e.g. ACP, CCDAP, TheSky). A user reported that ACP in particular sometimes sends a command when tracking is disabled so enabling this option should allow ACP to function more harmoniously with the driver.

V5.05.14 - 2013-May-15 BETA

-  Added Windows Process priority option to Setup (advanced section) and the virtual hand box. Default priority is set to "Above Normal".

V5.05.13 - 2013-Apr-20 BETA

-  Check for latest driver version is now also done in setup dialog window.
-  Added new internal commands to:
-  Allow reading/writing of AP.INI file values for automated setup of the driver by APCC.
-  Return the full path of AP.INI
-  Return a comma separated string of all values in AP.INI
-  Return the log directory and current Log File name

V5.05.12 - 2013-Mar-30 BETA

-  Added new Mount Types: Ap1100GTO and AP1600GTO
-  Added automatic check for updates (can be disabled in setup dialog in advanced settings).
-  Added new RAW commands for compatibility with APCC Horizons

V5.05.11 - 2012-Dec-31 BETA

-  For Rev >= S chips when setting meridian delay first read the current meridian delay value from the mount and only change if different.

V5.05.10 - 2012-Dec-02 BETA

-  Fixed "Clear Meridian Delay" when controller revision >=  "S".

V5.05.09 - 2012-Nov-26 BETA

-  Fixed an issue with the Meridian delay and chips with revisions >="S" .

V5.05.08 - 2012-Oct-24 BETA

-  AP RAPAS Fix for zoomed Southern hemisphere. Improved graphics.
- Fixed issue with Tracking Rate implementation for GTOCP2.

V5.05.07 - 2012-Sep-09 BETA

-  Minor fixes to Right Angle Polar Alignment Scope Utility
-  Pass through APCC timeouts to the driver.

V5.05.06 - 2012-Sep-03 BETA

-  Unchecking "Keep Synced to PC" now should work correctly.
-  Added new Right Angle Polar Alignment Scope Utility. Accessed through the menu, system tray, or a button on the ASCOM driver panel..

V5.05.05 - 2012-Aug-30 BETA

-  Fixed Park 3 in Southern Hemisphere when "Convert Alt/Az to RA/Dec" is checked.
-  Added PEC Record button.
-  Don't allow set time to PC time within 2 minutes of midnight.
- Added new GOS state "Auto-Park enabled". An asterisk identifies when autopark is enabled and unparked  (i.e., status will be: "Unparked*").

V5.05.04 - 2012-Jul-07 BETA

-  Clear Slew Abort Flag whenever a new slew is issued.
-  If APCC is in use disable Pointing Corrector and Tracking Rate Correction when a Park command is issued.

V5.05.03 - 2012-Jun-19 BETA

- Fixed  driver exceptions that would happen if parked and user tries to GOTO a  bookmark.
- Add a pop up dialog box to  stop accidental movements and tracking rate changes when the mount is parked.

V5.05.02 - 2012-Apr-04 BETA

- Swapped position of Alt/Az labels for consistent ordering of read back values.

V5.05.01 - 2012-Mar-15 BETA

- Fix to the Slew East before park (but only slews East when West/above pole, East/below pole)
- Fixed flickering of CwUp at park 1 position.
- Safe Slews should now be invoked when parking if "Convert Alt/Az to RA/Dec slews" is checked
- When mount tracking is stopped Alt/Az is queried instead of calculated so that the Alt/Az doesn't appear to be changing.
