Version:
2.7.8 |
Version 2.7.8, Jul 26, 2009
Corrections:
- Some serial port drivers produce 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 |
Version 2.7.7, May 08, 2009
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 |
Version 2.7.6, Jul 22, 2008
Enhancements:
-
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 |
Version 2.7.5, Nov 11, 2007
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 |
Version 2.7.4, Aug 23, 2007
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.
