Dimension Information for the Custom PC Board Area
Utilization of the empty space within the 34959A breadboard module is left
entirely up to the user. However, assuming you want to most fully utilize the space
provided, output signals through the Dsub ports, and connect your board securely
to the supplied ribbon cable headers, four detailed dimension drawings are
provided in this section to assist with your PC board fabrication.
The figure on
page 25 illustrates the external dimensions of the largest PC board
that will fit into the space provided, and provides distances on the plane of that
board from the datum to the following locations:
– The 15 PC board mounting holes in the sheet metal base.
– Pin 1 of the board mounting position for the 26-pin ribbon cable connector
carrying digital I/O signals and control power to/from header P102.
– Pin 1 of the board mounting position for the 40-pin ribbon cable connector
carrying relay drive signals and control power from header P101.
– The center of the two user-supplied Dsub output connectors.
– The mounting holes for the two Dsub connectors. Note that this dimension,
labelled “Dimension A” on the drawing, varies with the selection of Dsub
connector used (e.g., DB50, DB78M, DB78F).
The figure on page 26 shows the mounting footprints for the recommended
DB50(M/F) connectors. The two figures on page 27 show the footprints for the
recommended DB78M and DB78F connectors, respectively. The part numbers for
the recommended connectors are listed in the following table:
