There are 3 types of Miran cards. The first two were accessible via AX x etc if the card was installed in a Option 11c system in the main cabinet.
Version 3 was in effect a 32 port media card that had a inbuilt compact flash flash that you could look at on your computer. Best to look for a file called "_keycode.dat". This file contains the keycodes.
If you can access the card OK, then you can select 2 for Pack Administration as shown below
