H2TU-C-319 LIST 4E CARD-EDGE CONNECTOR

Figure33 shows the pin assignments of the card-edge connector on the H2TU-C-319 List 4E card. The function

of its segments (S1, S2, and S3) are described beginning with “Test Access” on page28. Note that only the set of

Standard 3192 alphanumeric connector pins to Segment 3 (A through L and 1 through 10) are labeled on the

backplane of the HMS-358 shelf. The outer set of pin numbers are for reference only and do not appear on the

backplane. The AUX DSX-1 Segment 1 port can be accessed either by its wire wrapped pins or from mass

connector P11 (TX) and P10 (RX) on the HMS-358 backplane.
