Signal Connection Descriptions
Analog Input Ground—The pins are
connected to the analog input ground
signal. ACH<0..15> signals should be
referenced to AIGND.
Analog Input Channels 0 through 15—
These channels are single-ended.
Digital Ground—This pin supplies the
reference for the digital signals at the I/O
connector as well as the +5 VDC supply.
-12 VDC Power Supply Output Pin—
The maximum current is 5.0 mA.
+12 VDC Power Supply from the
Computer Bus—This power line has a
0.5 A self-resetting fuse in series.
Digital Input Data Lines—These signals
are TTL-compatible, digital input lines.
DIN7 is the MSB, DIN0 the LSB.
Digital Output Data Lines—These
signals are TTL-compatible, digital
output lines. DOUT7 is the MSB,
DOUT0 the LSB.
Output of Counter 1—This signal
outputs the inverted programmed
waveform of counter 1.
External Interrupt—This pin is used for
input of the external interrupt signal.
