Protected program encryption and decryption allow you to encrypt a
protected program so that it is unreadable when it is uploaded. Protected
programs in encrypted form can only be uploaded or downloaded by using
the Upload and Download utilities of ODS or the Mini DNC package.
Use the {NCRYPT MODE} softkey to enable the protected program
encryption option. If the control displays the {NCRYPT MODE} softkey
in reverse video, the encryption option is enabled. When the encryption
option is enabled, protected programs are encrypted when they are
uploaded to ODS or the Mini DNC package. When downloading
encrypted protected programs to the control, they are decrypted and loaded
into the protected program directory.
Protected programs are encrypted or decrypted through a translation
process that reads in a program and translates the characters one at a time
to another character. Character translation is based on a character
encryption/decryption table that you must set-up before programs can be
encrypted or decrypted.
Important: If the encryption/decryption table is modified after a protected
program is uploaded to ODS or the Mini DNC package, the program can
no longer be decrypted when it is downloaded to the control.
To set-up the character encryption/decryption table:
1. Select the protected part program directory.
2. Press the {SET-UP NCRYPT} softkey.
