3.2 Connection to the PHI

The AMC131M03EVM board communicates with the PHI through a shrouded, 60-pin connector, J6. There are two round standoffs next to J6 with Phillips-head screws. To connect the PHI to the EVM, remove the screws, attach the PHI to the EVM, and replace the screws into the standoffs. The screws secure the EVM to the PHI and verifies the connection between the boards.

Table 3-1 lists the different PHI connection and their functions.
