HD-D-sub 15 Connector
This connector has the same size shell as a DE-9 (D-sub 9)
connector, but has a high-density pin configuration that permits 15 pins
to be included by using three rows. Here's a good set of figures for
HD-D-sub-15 male and female connectors, as viewed from the pin side (not
the solder side).
