This chapter describes the connectors of the DAQ/PXI-20XX, and
the signal connection between the DAQ/PXI-20XX and external
devices.
3.1 Connectors Pin Assignment
The DAQ/PXI-20XX is equipped with one 68-pin VHDCI-type con-
nector (AMP-787254-1). It is used for digital input/output, analog
input / output, and timer/counter signals, etc. One 20-pin ribbon
male connector is used for SSI (System Synchronous Interface) in
DAQ-20XX. The pin assign-ments of the connectors are defined in
Table 3-1 and Table 3-2.
