Connecting Signals

NI 653x Cable Adapter User Guide
The NI 653x cable adapter provides connectivity to up to 32 of the
single-ended DIO channels of an NI high-speed DIO device. Each DIO,
PFI, and clock channel of the NI high-speed DIO device connects to a
corresponding pin on the NI 653x cable adapter. The 32 DIO channels are
directly connected between the two bulk connectors. PFI <0..5> from the
NI 6535/6536/6537 VHDCI connector are connected to a 6-position screw
terminal. PFI <0..7> from the NI 6533/6534 68-pin DAQ connector are
connected to an 8-position screw terminal.
PFI channels must be manually connected through screw terminals for
flexibility and to ensure correct signal routing. You can make connections
between the PFI channels using 22- to 26-gauge wire.
The NI 6533/6534 devices have specific applications for PFI channels and
thus require custom wiring to be compatible. An example of how to make
these connections is provided in the
Figure 4 shows the screw terminal locations on the NI 653x cable adapter.
