When you press the
{UPDATE & EXIT}
softkey, the control does a
compile/check of the encryption/decryption table to determine that
no duplicate characters exist and that no characters were left blank.
If a character is: the control displays: and moves the cursor:
entered twice “CHARACTERS CAN ONLY
BE ENTERED ONCE”
to the first occurrence of that character
in the encryption/decryption table
left blank “NO LOCATIONS CAN BE
LEFT EMPTY”
to the first blank location in the
encryption/decryption table
Once the encryption/decryption table is created and you press the
{NCRYPT MODE}
softkey, 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.
To prevent the encryption/decryption table from being lost during system
power failures and battery-backup failures, store it in the control’s backup
memory by using these steps:
1. Select the protected part program directory.
2. Press the
{SET-UP NCRYPT}
softkey.
