corresponding programming image when the date is on or between the dates specified. The
Cyclone has an onboard battery and clock which keeps a clock running even when power to the
Cyclone is removed. This clock date is the one used for comparison to the UTD Date specified in
the image. The ability to limit programming to a date is useful for making sure that an image will
stop working after a period of time. This could be for security purposes, or to make sure that a new
and updated image will need to be uploaded to the Cyclone after a period of time (for instance, to
not allow a firmware more than a year old to be programmed onto a target).
6.1.8.2.2 Limit Number of Programs Allowed
When “Limit Number of Programs Allowed” is checked and a number is specified in the
corresponding box (minimum = 1), the Cyclone operator will only be able to execute a number of
successful programming operations of this programming image less than or equal to the number
specified. The current programming count can be displayed on the main screen of the Cyclone or it
can be seen on the image's statistics page (see
Section 6.1.8.2.4 - Image Restriction
).
6.1.8.2.3 Limit Number of Failures Allowed
When “Limit Number of Failures Allowed” is checked and a number is specified in the
corresponding box (minimum = 1), the Cyclone operator will only be able to execute programming
operations on the current image until the maximum number of errors specified has been reached.
This restriction exists largely to prevent an operator from intentionally generating an error as part
of the programming process in an attempt to circumvent the count restrictions. A recommended
limit on this number would be on the order of 5% of the allowed programming counts.
6.1.8.2.4 Image Restriction Statistics
Statistics related to any specified restrictions for the currently selected programming image may
viewed by navigating in the touchscreen menu to
Current Image Operations - Show Current Image
Stats.
For more information on viewing programming image stats, see
Image Restriction Stats (Requires FX or ProCryption Security License Activation)
In addition, the statistics for Number of Programs & Maximum Allowed can be set to display on the
home screen by navigating in the touchscreen menu to
Configure Cyclone Settings -> Configure
Screen -> Configure Home Screen
. For more information on how to configure the Cyclone’s home

Store Image To Cyclone
“Store Image to Cyclone” allows the current configuration to be programmed into the Cyclone. The
Cyclone will then be ready for operations. After you click “Store Image To Cyclone,” the Cyclone
Control GUI will pop up so that you can choose the Cyclone onto which you wish to save the SAP
image.

The Cyclone Control GUI drop-down list allows the user to select from all the Cyclones available.
