ESCRIPTION
:
MAC is an acronym for Message Authentication Code. The MAC WORKING KEY is used to
verify messages to and from the terminal. The MAC WORKING KEY is a 16-character string,
consisting of the digits 0-9 and the letters A-F. Your processor must provide you with the MAC
WORKING KEY. If a MAC authentication attempt on a message fails, the message will fail. This
is a security precaution.
For security reasons, when entering this key, a ‘*’ is displayed in place of the actual character.
Since it is not possible to view the key while it is entered, the key must entered in twice to make
sure it was entered properly.
To enter a digit 0-9, simply press the key that has that digit, and a ‘*’ will appear. To enter the
letters A-F, first press the <BLUE> key, then press the key that has the letter you want on it. The
first press of the key will display the first character above the number. Subsequent presses will
display the characters in sequence. When the character you want is displayed, press the <RIGHT
ARROW> key to ‘lock in’ the letter. If your next character is a letter, you must press the <BLUE>
key again. Press the <CHANGE> key to clear the entry and start over. Press the <LEFT ARROW>
key to back up and erase a character.
Normally, the MAC WORKING KEY contains only one part. However, some keys may contain
multiple parts. If this is the case, separate individuals will hold the parts. If your key has multiple
parts you must answer the question “ANOTHER KEY PART?”, with a YES until all parts are
entered.
