In order to expand your MAC8 to a MAC32, you need to add the following hardware to the 1st stage of your MAC unit:

• One signal conditioning card
• One relay card
• One analog to digital converter

You also need to add a 2nd stage:

• One 2nd stage assembly which includes the chassis, two signal conditioning cards, two relay cards and one slave controller card;
• Two 4RU side panels;
• One 4RU front panel;
• Set of fastening screws;
• One vertical expansion bus connector card;
• Two 5-wire ribbon cables;
• One 4-wire dual ribbon cable (for older MAC front panels); and
• One 6A fuse (to replace the 3A fuse)

All these items form one MAC Expansion Kit (MEXPK) and two MAC Conditioning Card Kits (MCCK).
