MAC is an acronym for Message Authentication Code. The MAC Master Key provides key protection
during manual entry or downloading of the PIN Working Key. Note: A MAC Master Key will only be used
when it is required by the processor, and has been enabled as a communication configuration option.
If required, obtain the MAC Master Key from the processor. It must be entered before the MAC Working
Key can be downloaded.
The MAC Master Key normally consists of a two part, 64-character Triple DES key (32 characters in both
key parts) . The MAC Master Key can be made up from the hexadecimal character set (the numbers 0- 9 and
the letters A, B, C, D, E, F).
Follow these steps to enter the MAC Master Key:
The first screen to appear asks you to indicate whether this is a “New Key” or “Add Part” to an
existing key that was already entered. Use the
LEAR > button on the keypad to select (highlight)
the key type field. Use the RROW > button on the keypad to alternate between the 2 options. Select
the “N EW K EY ” option when entering the a new key or the first part of a new key. After entering the
first part (32 characters), you will automatically be prompted to enter the second part.
