H2TU-C-319 LIST 4E CARD-EDGE CONNECTOR
Figure 33 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 page 28. 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.
