The below table lists the 30-pin connector pinouts used in the Engineering Sample of the below OPNs:
MBF2H512C-AECOT, MBF2H512C-AESOT, MBF2H512C-AEUOT, MBF2H532C-AECOT, MBF2H532C-AESOT, MBF2H516C-CECOT, MBF2H516C-CESOT, MBF2M516C-CECOT, MBF2M516C-CESOT, MBF2H536C-CECOT, MBF2H536C-CESOT, MBF2H536C-CEUOT.
PACK_ID[2:0] signals allow for 8 unique card IDs. The system configurator sets the unique value per card via the connecting harness.
