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 Hexadecimal (“Hex”) characters A-F. If a MAC authentication
attempt on a message fails, the message will not be processed. 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 being entered, the key must entered twice to make
sure it was entered properly.
To enter a digit 0-9, simply press the key that has the desired digit, and a ‘*’ will appear. To enter
a Hex character (A through F), first press and hold down the key. While holding down
the key, press the numbered key (1-6) that corresponds to the character you want to enter,
as listed in the table on-screen (1=A, 2=B, 3=C, 4=D, 5=E, 6=F). A ‘*’ character will appear.
Release the key. Repeat for each character in the key. Press the key to clear
the entry and start over. Press the 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 and enter the next key
part until all parts are entered.
