AO GND
—
—
Analog Output Ground—AO GND is the reference for
AO <0..3>. All three ground references—AI GND, AO GND,
and D GND—are connected on the device.
Note: AI GND, AO GND, and D GND are isolated from earth
ground and chassis ground.
D GND
—
—
Digital Ground—D GND supplies the reference for input
PFI <0..5>/P0.<0..5> and output PFI <6..9>/P1.<0..3>. All
three ground references—AI GND, AO GND, and
D GND—are connected on the device.
Note: AI GND, AO GND, and D GND are isolated from earth
ground and chassis ground.
PFI <0..5>/P0.<0..5>
D GND
Input
Programmable Function Interface or Static Digital Input
Channels 0 to 5—Each of these terminals can be individually
configured as a PFI terminal or a digital input terminal.
As an input, each PFI terminal can be used to supply an
external source for AI or AO timing signals or counter/timer
inputs.
Note: PFI <0..5>/P0.<0..5> are isolated from earth ground
and chassis ground.
PFI <6..9>/P1.<0..3>
D GND
Output
Programmable Function Interface or Static Digital
Output Channels 6 to 9—Each of these terminals can be
individually configured as a PFI terminal or a digital output
terminal.
As a PFI output, you can route many different internal AI or
AO timing signals to each PFI terminal. You also can route the
counter/timer outputs to each PFI terminal.
Note: PFI <6..9>/P1.<0..3> are isolated from earth ground
and chassis ground.
NC
—
—
No connect—Do not connect signals to these terminals.
CAL+
—
—
External Calibration Positive Reference—CAL+ supplies
the positive reference during external calibration of the
NI 6236.
CAL–
—
—
External Calibration Negative Reference—CAL– supplies
the negative reference during external calibration of the
NI 6236.
