Connecting Signals
The NI 653 x 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 653
x 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
Custom Wiring Example section.
Figure 4 shows the screw terminal locations on the NI 653 x cable adapter.
