CSC-1 Software Revision History

The table below shows the CSC-1 software revision history. Later revisions will always have a higher revision number but the numbers are not necessarily consecutive. The column labelled Importance provides (on a scale of 1 to 3) an indication of how important it is to upgrade from an earlier revision to the new revision. The grades are as follows:

A minor functional improvement or trivial bug fix has occurred - probably not worth upgrading.
A major functional improvement has been introduced or a significant, but not safety critical, bug has been fixed - upgrade recommended.
A safety critical bug has been identified and fixed - upgrade strongly recommended.

Revision	Date	Importance	Description of Changes
694	14/07/2009	2	Added "Takeoff Mode". Fixed small glitch that occurred when PWM acceleration was enabled.
646	12/09/2008	1	Further improvements to feathering. Can now cycle through parameters either forwards or backwards.
638	20/07/2008	1	Now compatible with GT feathering propellers.
606	24/06/2008	2	Fixed bug that made feathering stop prematurely if initiated in CRS/CLM modes. Now inhibits PWM acceleration if RPM is changing as required. New "smart" RPM sampling code that minimises overshooting when changing pitch.
583	05/01/2008	2	Fixed ancient bug that caused crash after editing CLM RPM parameter. RPM display now to nearest 10 rather than 50. Further CSC-1/G PWM and feathering Improvements.
546	24/02/2007	2	CSC-1/G PWM Improvements.
488	06/11/2006	2	CSC-1/G now supports feathering with Woodcomp SR3000.
468	04/10/2006	1 (2 for Jabiru engines)	Implemented %power display for Jabiru 3300 engine. New software revision numbering scheme.
1.162 (aka 455)	19/06/2006	1	Various mods required to support latest CSC hardware revision. Eliminated RPM display jitter.
1.159	12/01/2006	1	Now supports ignition lead tacho pickup. When used with a fuel injected engine, can display percentage power or approximate fuel flow. CSC-1/G now supports PWM to reduce speed of pitch motor (required for Woodcomp SR3000).
1.155	25/05/2005	1 (3 for Jabiru engines)	Fixed bug in RPM measurement for Jabiru engines. Improved reliablity of CSC-1/G motor current measuring at low currents. Various minor improvements.
1.152	04/04/2005	1	Now inhibits pitch reduction in manual mode when RPM reaches 100 below the limit RPM.
1.151	09/07/2004	1	Added Coarse Pitch Limit.
1.150	06/03/2004	1	Added support for PV55.
1.148	22/12/2003	1	Generic version of CSC-1 introduced. Added parameter to explicitly specify whether a Pitch Sensor is fitted. Added parameter to allow tacho signal frequency to be divided (for non-Rotax engines). Added feature to suppress pitch reduction when throttle closed in cruise mode.
1.146	10/6/2003	1	Fixed bug that made controller erroneously enter cruise mode after leaving setup mode.
1.145	24/5/2003	1	Added ability to modify stored tacho time through new parameters. Reduced default value of 'Tacho Level' parameter to 100 to cope with loading effect of Rotax analogue tacho. Reduced default values of 'MAP 1' and 'MAP 3' to slightly extend the lower limit of the MAP sensor. Added parameter to explicitly specify whether a MAP sensor is fitted or not. Reduced default climb mode target RPM to 5600.
1.142	1/3/2003	N/A	Initial revision.

To upgrade the software in your CSC-1, the unit must be returned to Smart Avionics.

The upgrade itself is free but a small charge is made to cover the cost of returning the unit to you securely.

It is the owner's responsibility to ensure that the controller is suitably packed and a secure method of carriage used to send the controller to Smart Avionics. In the UK, Royal Mail special delivery is a good service. This is an inexpensive, insured, next day delivery service direct from your local post office.

Upgrading is very quick and units will normally be returned within 24 hours.

If you wish to upgrade your controller please contact support@smartavionics.com. If you do not have access to email, please contact the supplier of the controller.
