Description
Analog Input Ground—These pins are the reference point
for single-ended measurements and the bias current return
point for differential measurements. All three ground
references—AIGND, AOGND, and DGND—are connected
together on your VXI-MIO Series module.
Analog Input Channels 0 through 15—Each channel pair,
ACH<i, i+8> (i = 0..7), can be configured as either one
differential input or two single-ended inputs.
Analog Input Channels 16 through 63—Each channel pair,
ACH<i, i+8> (i = 16..23, 32..39, 48..55), can be configured
as either one differential input or two single-ended inputs.
Analog Input Sense—This pin serves as the reference node
for any of channels ACH <0..15> in NRSE configuration.
Analog Input Sense—This pin serves as the reference node
for any of channels ACH <16..63> in NRSE configuration.
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.
External Reference—This is the external reference input for
the analog output circuitry. This pin is not available on the
VXI-MIO-64XE-10.
Analog Output Ground—The analog output voltages are
referenced to this node. All three ground references—
AIGND, AOGND, and DGND—are connected together on
your VXI-MIO Series module.
Digital Ground—This pin supplies the reference for the
digital signals at the I/O connector as well as the +5 VDC
supply. All three ground references—AIGND, AOGND,
and DGND—are connected together on your
VXI-MIO Series module.
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 circuit breaker is self-resetting.
