Appendix B: Loading Datacryptor Unit Software
Datacryptors are factory pre-loaded with the required ‘application’ software and protocol data.
However, if a new version of software needs to be loaded into a Datacryptor, the following
procedure describes how to carry out the operation using the Image Loader utility, which will be
provided with the new version of software.
Note: The process of application upgrade can also be used to upgrade the bootstrap of
the unit. If a unit is being upgraded to application software greater then 1.07.04,
then the user is advised to upgrade the bootstrap software to the latest version,
as this is required for the algorithm retention feature.
1. Connect the Datacryptor to the COM port of the PC that has access to the Image Loader
utility (imgload.exe), and power it on.
2. Start the imgload.exe application.
WARNING: Do not power the Datacryptor unit down during a bootstrap
upgrade; this may cause the unit to enter an unrecoverable state. For this
reason, it is recommended that the Datacryptor is connected to an UPS
(Uninterruptible Power Supply) during this process.
