USB Drivers for the CNS Clock II: Version 2.6.2.0 (25-May-2010).

This version eliminates the problem where Windows would detect the CNS Clock II as a mouse which requred special action by the user.

Uncompress this library file to a temporary location and use one of the newly created directories to load the USB driver when Windows detects new hardware or use with the update driver function to change to the latest USB driver. The directory "USB Driver" supports Windows Server 2008, Windows Server 2008 x64, Windows Vista, Windows Vista x64, Windows XP, Windows XP x64, Windows 2000, Windows Server 2003, and Windows Server 2003 x64. The directory "USB Driver Old - Win 98 and ME" supports Windows 98 and Windows ME.

Latest
Version:
2.7.10

Enhancements:

• Improve detection, initialization and mode switching for Synergy SSR-6T receivers.
• Implemented a decoder for the @@Bd message.
• Provide NMEA support for u-blox receivers in the Manual Command dialog window.
• Implemented a checkbox in the GPS Receiver Serial Port Setting dialog box that will minimize the GPS receiver initialization. Use of this capability speed up the program startup and will preserve some special settings that may be in effect before start-up. However, the receiver mode (binary, NMEA, etc.) cannot be changed when this capability is activated.
  

Corrections:

• Correct the management of Motorola and iLotus receivers when switching between binary and NMEA modes.
• Reinitialize the manual command dialog entries when changing GPS receiver modes.
• Set the @@Ci default parameter correctly in the manual command dialog.
• Assure that the Set Reference Location selections work correctly for receivers in the Motorola binary mode. These receivers must be in navigation (3D) mode before the position data is loaded and then must be returned to the selected mode. This is now handled automatically.

Latest
Version:
2.7.9

Enhancements:

• Implement support for the i-Lotus TX Oncore receiver.
• Implemented the new TELNET Get/Set Reference Position command.
• Provide support for the Synergy Systems SSR-6T receiver. This
  receiver has the same footprint as an M12 series Motorola/iLotus
  receiver. The SSR-6T has a uBlox LEA-6T receiver that operates in
  uBox NMEA or Binary mode. A version of this board has
  a processor that permits emulation of M12 series messages as well as
  other modes. Added the @@Wb message to switch the SSR-6T from M12
  to uBlox message mode.Added "@@Wc" to switch to the boot loader.
• Added a new checkbox in the manual reference location dialog box
  titled "Load reference location on program startup." The default
  is off.
• Increase the number of recognized COM ports from 64 to 128.
• Added a mode for CMC Superstar Rx Only.

Corrections:

• Correct an error that impeded correct startup in Motorola Binary if
  the serial port is set to other than 9600 baud.
• Corrected the order of fields in the @@Ha raw data output. Added
  reserved fields for completeness.
• Make Vehicle ID field visible at the end of the @@Ha decoded message
  even if blank by adding quotes
• Changed the sawtooth correction message at the beginning of the
  averaging files to differentiate between software sawtooth corrected
  data, raw data and external TIC data used in the file.
• Stop @@Hb from updating system parameters as it conflicts with @@Ha.
• Changed the manual command dialog box to non-model so that it now
  allows the user to perform other functions outside this dialog box
  while the manual command dialog box is open.
• Corrected an error that caused a program crash when satellite PRN
  numbers greater than 32 were detected. These PRNs are associated
  primarily with augmentation satellites.
• Corrected a number of bugs that will improve the operation and
  stability of Tac32 and Tac32Plus.
• Ensure that all unused rows in the satellite data table are erased.
• Change the default elevation mask for Precision Timing mode to
  10 degrees for all receiver types.
• The TELNET function was not working in the UNICODE version of Tac32Plus.
  This is now fixed.
• Corrected the header and data fields for the Motorola PVT format log
  so that the header correctly describes the log contents. Changed the
  order of some fields for consistancy between entries created by the
  @@Ha and the @@Hb messages from 12 channel receivers such as the
  M12M used by the current generation of CNS Clock II clocks.
• Improve the performance of the Navigation Status and Antenna
  Status panes in the Status Bar.

Version:
2.7.8

Enhancements:

• Implement support for the u-blox LEA-5T.

Corrections:

• Some serial port controllers would not work with the Time Interval Counter. This is fixed.
• Some serial port drivers produced faulty outputs for the 1PPS signal control lines. This is now managed correctly if it occurs.
• Spell out "Motorola" instead of using "Mot" (e.g., "Motorola Binary" replaces "Mot Bin".
• Improved the efficiency of processing certain Motorola Binary messages.
• Eliminate intermittent exception when closing the program.

Version:
2.7.7

Corrections:

• A configuration management error prevented the fix that allows use of any baud rate for any receiver from 2.7.6 to function on some variations of the software. This is now fixed.

Version:
2.7.6

Enhancements:

• Merge Tac32Multi into Tac32Plus
• Updated the CMC hardware-software identification message (#45) decoder to reflect more recent message data specification and to display more information.
• Allow use of any baud rate for any receiver. New models of some receivers are implementing new data rates.

Corrections:

• Correctly display PRN32 on the Satellite Az-El Chart.
• Fixed a memory leak.

Version:
2.7.5

Enhancements:

• Recognize the iLotus built M12M based on the new SiRF copyright notice.

Corrections:

• Change the "Bad Almanac" message to "Cold Start or Bad Almanac" for the M12 series receivers.

Version
2.7.4

Enhancements:

• Added 100PPS support for the CNS Clock II. The CNS Clock II is unique in that it provides a precision 1PPS even when in 100PPS mode so that normal operations can continue in 100PPS mode.

Corrections:

• Correctly identify the new iLotus M12M receiver modules. These modules are designed by Motorola but built by iLotus.
• Added interim support for the SIGNAV TM3-1 receiver which is intended to be a Motorola M12 Timing receiver clone.
• CMC (Marconi) message receive was broken in Version 2.7.3 when converting to unicode and is now fixed.
• The CMC receiver's DGPS Status message was being derived from the wrong message thus giving false indications. Also, the CMC DGPS status tells if DGPS is enabled, not if it is being received, so the display message was changed.
• In decoding the CMC message 33 it was found that the satellite table was incompletely cleared resulting in unused satellites remaining on the screen and occasionally even showing duplicate satellites. This is now fixed.
• Identify CMC Allstar and Superstar receivers separately. Improve CMC receiver initialization, especially disabling undesired messages so that the Superstar correctly displays its data on TAC32's screens.
• Fix the default size of the main window for first time users.
