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:
2.7.8

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.
