AISENSE
AIGND
Input
Analog Input Sense—This terminal
serves as the reference node for any
of channels ACH <0..15> in NRSE
configuration.
DAC0OUT
AOGND
Output
Analog Channel 0 Output—This
terminal supplies the voltage output
of analog output channel 0.
DAC1OUT
AOGND
Output
Analog Channel 1 Output—This
terminal supplies the voltage output
of analog output channel 1.
EXTREF
AOGND
Input
External Reference—This terminal
is the external reference input for the
analog output circuitry.
AOGND
—
—
Analog Output Ground—The analog
output voltages are referenced to these
terminals. All three ground
references—AIGND, AOGND, and
DGND—are connected together on
your E Series device.
DGND
—
—
Digital Ground—These pins supply
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 E Series device.
DIO<0..7>
DGND
Input or
Output
Digital I/O Signals—DIO 6 and 7
can control the up/down signal of
general-purpose counters 0 and 1,
respectively.
+5 V
DGND
Output
+5 VDC Source—These terminals are
fused for up to 1 A of +5 V supply.
The fuse is self-resetting.
