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:

Select the protected part program directory.

Press the

{SET-UP NCRYPT}

softkey.
