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 and battery-backup failures, store it in the control’s backup memory
by using these steps:

Select the protected part program directory.

Press the

{SET-UP NCRYPT}

softkey.
