Successful entry of both passwords will grant access to the Key Management screen.
From the moment the Key Management area is entered, a 5 minute timer begins. At the end of 5
minutes, regardless of what you are doing (entering a master key for example) the Key
Management area times out and you will be taken back to the Host Setup menu. Making a
mistake during this process can start a 30 second reset timer.
If you are ever forced to wait for the 30 second retry timer, back all the way out of the menus and
wait a full 30 seconds before retrying or the timer will not reset.
KEY MODE
This option sets the type of master key you will be loading (TDES, DES, MAC etc.) Refer to
Addendum C for Key Mode descriptions and instructions.
MASTER KEY INDEX
The ATM will hold up to 16 individual Master Keys. Check with your processor to find if they are
expected to be at a certain location. For example Coredata is always installed at index #9, most
other processors are installed at index #0 or #1. The ATM will only use the key that the index is
set to regardless of how many keys are installed. To set the index simply press the button
labeled Master Key Index and then enter the number you want it set to (enter as a 2 digit number
... 00, 01, 02, 10, 11 etc.) press Enter when done. Press Check Master Key to see a list of
currently installed keys.
CHECK MASTER KEY
This will show the list of available master keys and their appropriate checksums. The checksum
is a 4 digit number calculated from the two 16-digit numbers of your master key that provides a
means to verify the master key is correct. When your processor provides your Master Keys, they
will also give you the 4 digit checksum. If after entering your Master Key this checksum does not
match, try reentering your master keys or contact the processor.
EDIT MASTER KEY
This is where you enter your two 16-digit Master Keys (provided by your processor). After
pressing Edit Master Key, you will be prompted to enter an index where you want this key stored.
If you do not know which index to use, contact your dealer or processor. Generally, you should
use index 0 or 1 unless otherwise instructed.
