+Analog Input Channel 0 through 3—The PCI-4453 uses
+ACH<0..1> and the PCI-4454 uses +ACH<0..3>. Analog
Input Ground (AIGND) is the reference point for
single-ended measurements.
Analog input shield—Each of these pins is tethered to
AIGND through a common-mode choke.
Chassis Ground—These pins are connected to the chassis
ground of your computer through the metal mounting
bracket of the PCI-4453/4454. All ground
references—AIGND, AOGND, CGND, and DGND—are
connected together on your PCI-4453/4454, but each serves
a separate purpose.
+Analog Output Channel 0—This pin supplies the analog
non-inverting output channel 0. This pin is available only on
the PCI-4453. Analog Output Ground (AOGND) is the
reference point for the analog output voltage.
+Analog Output Channel 1—This pin supplies the analog
non-inverting output channel 1. This pin is only available on
the PCI-4453. Analog Output Ground (AOGND) is the
reference point for the analog output voltage.
Analog output shield—Each of these pins is tethered to
AOGND through a common-mode choke.
+5 VDC Source—These pins are fused for up to 1 A and
supply power to the DSA signal conditioning accessories.
The fuse is self resetting.
Digital Ground—This pin supplies the reference for the
+5 VDC supply. All ground references—AIGND, AOGND,
CGND, and DGND—are connected together on your
PCI-4453/4454, but each serves a separate purpose.
