Table 4-1 shows the I/O connector signal descriptions for the 6034E and
6035E.
Table 4-1. I/O Connector Signal Descriptions
Signal Name Reference Direction Description
AIGND — — Analog Input Ground—These pins are the reference point
for single-ended measurements in RSE configuration and
the bias current return point for differential measurements.
All three ground references—AIGND, AOGND, and
DGND—are connected together on your device.
ACH<0..15> AIGND Input 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.
AISENSE AIGND Input Analog Input Sense—This pin serves as the reference node
for any of channels ACH <0..15> in NRSE configuration.
DAC0OUT
1
AOGND Output Analog Channel 0 Output—This pin supplies the voltage
output of analog output channel 0.
DAC1OUT
1
AOGND Output Analog Channel 1 Output—This pin supplies the voltage
output of analog output channel 1.
AOGND — — 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 device.
DGND — — 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 device.
DIO<0..7> DGND Input or
Output
Digital I/O signals—DIO6 and 7 can control the up/down
signal of general-purpose counters 0 and 1, respectively.
+5 V DGND Output +5 VDC Source—These pins are fused for up to 1 A of
+5 V supply. The fuse is self-resetting.
SCANCLK DGND Output Scan Clock—This pin pulses once for each A/D conversion
in scanning mode when enabled. The low-to-high edge
indicates when the input signal can be removed from the
input or switched to another signal.
EXTSTROBE* DGND Output External Strobe—This output can be toggled under software
control to latch signals or trigger events on external devices.
