Connector Pinouts

The following pinout diagrams describe the connection from the PCI CD/CDa board to the cable. The

board uses a high-density 80-pin I/O connector (EDT part number 012-10026), with a straight-shielded

backshell (EDT part number 013-10287) or right-angle backshell (EDT 013-00458).

NOTE Do not connect your own circuits to the unused pins, as they may be internally connected.

Table 3 applies to the PCI CD when loaded with either

pcd_src.bit or pcd_looped.bit, or the PCI

CDa when loaded with

pcda.bit.
