Analog Input Channels 0 through 3 ground—These pins are
the bias current return point for differential measurements.
ACH <2..3> GND signals are no connects on the
PCI-6111E.
Analog Input Channels 0 through 3 (+)—These pins are
routed to the (+) terminal of the respective channel's
amplifier. ACH <2..3> + signals are no connects on the
PCI-6111E.
Analog Input Channels 0 through 3 (–)—These pins are
routed to the (–) terminal of the respective channel's
amplifier. ACH <2..3> – signals are no connects on the
PCI-6111E.
Analog Channel 0 Output—This pin supplies the voltage
output of analog output channel 0.
Analog Channel 1 Output—This pin supplies the voltage
output of analog output channel 1.
Analog Output Ground—The analog output voltages are
referenced to this node.
Digital Ground—This pin supplies the reference for the
digital signals at the I/O connector as well as the +5 VDC
supply.
Digital I/O signals—DIO6 and 7 can control the up/down
signal of general-purpose counters 0 and 1, respectively.
+5 VDC Source—These pins are fused for up to 1 A of
+5 V supply. The fuse is self-resetting.
Scan Clock—This pin pulses once for each A/D conversion
when enabled. The low-to-high edge indicates when the
input signal can be removed from the input or switched to
another signal.
External Strobe—This output can be toggled under software
control to latch signals or trigger events on external devices.
