2.4.4 Security Settings
The security settings provide some measure of protection against access to your image information by
unauthorized individuals, as well as a programmable limit to the number of device which can be programmed
from the image.
The Read Protect option prevents the ability to upload the image from the programmer and save it to a file
(i.e., the Image/Save Image to File option is not available for this image). Selecting this option has no effect on
the use of the image for programming devices, it simply cannot be read out of the programmer for storage on the
host PC.
The Restricted Count option allows you to limit the total number of devices which can be programmed
with this image. If this option is selected, the number of cycles indicated in the "Count" field will be the total
number of devices which may be successfully programmed with the image. Once the count is exhausted, subse-
quent attempts to program with this image will fail, and a new copy of the image must be loaded from the host to
authorize additional programming cycles. Note that, when the "Restricted Count" option is selected, the "Read
Protect" option will automatically be selected as well.
NOTE: Only the Read Protect option is available on older MPQ (V1) programmers. Both Read Protect
and Restricted Count functionality is available on V2 and later programmers.
The security settings for each image, as well as the number of cycles remaining for restricted-count images,
are shown in the Image Manager.
2.4.5 Serialization
Some MPQ programmers support serialization of the programmed devices. This feature allows the opera-
