and Visual C++ for Windows 95
SP0970-CD
DataAcq SDK Software Development Kit
for Windows 95
SP0945-CD
DT-LV Link data acquisition connection
to LabVIEW for Windows 95, on 3.5 in. 1.4 MB disk
SP0810-CL
STATIC DIGITAL I/O
Number of Lines
Two inputs, two
outputs (four out-
puts, DT7102); one
input is shared with
external trigger line
Outputs
TTL levels; fanout:
200mA (100 mA,
DT7102); outputs
are DMOS FETs,
open-drain type
and can be pulled
up to +32 V max
Inputs
Level sensitive; posi-
tive true; TTL levels;
present one LSTTL
load; unused inputs
are pulled high
PACER CLOCKS
Function
Independent A/D
and D/A pacer
clocks initiate A/D
or D/A conversions;
clocks are started by
software trigger or
(A/D only) a single
external trigger
Usable Range
A/D Pacer Clock—
1 Hz to 100 kS/s
single conversion
mode supports rates
below 1Hz
D/A Pacer Clock—
7.84 kS/s to 100 kS/s
Description
Consists of 2 MHz
frequency source and
a divider that can
produce any integer
value from 20 to 255
External Trigger
Function
—
synchronizes A/D
conversions with
outside event
Electrical—
Edge sen-
sitive; negative true;
TTL levels; presents
one LSTTL load; no
termination, unused
input is pulled high
DATA FIFOS
A/D—
A/D data val-
ues pass to the PC
Card Interface via a
512-sample FIFO
(1024-sample,
DT7102). This allows
Email

data transfers to
occur totally asyn-
chronously with A/D
operation
D/A (DT7102 only)—
D/A data values pass
from the PC Card
Interface via a 512-
sample FIFO. This
allows data transfers
to occur totally asyn-
chronously with D/A
operation
OPERATING MODES
A/D
Channel Selection—
single channel
channel scan
Operating Modes—
single conversion;
continuous conver-
sions
Simultaneous
Sampling (DT7102
only)—
the DT7102
supports simultane-
ous sampling on
pairs of input chan-
nels; in this mode,
the board’s two A/D
converters run
simultaneously,
permitting two chan-
nels to be sampled at
the same time (for
example, channels
0 and 1, 2 and 3, ... ,
14 and 15)
Data Transfer—
memory move; A/D
data is buffered by a
512-sample FIFO
(1024-sample,
DT7102) on bus
transfers
D/A (DT7102 only)
Channel Selection—
either DAC singly
or both DACs
simultaneously
Operating Modes—
single event; contin-
uous conversions
Data Transfer—
memory move
Standby
A standby mode is
available that
reduces power
consumption; board
automatically
switches to standby
mode if idle for more
than 25 seconds; in
standby mode,
digital outputs and
registers are still
active
GENERAL
Interface
Type II PC Card;
compliant with
PCMCIA PC Card
Standard Release 2.1;
I/O mapped into
system I/O space;
programmed I/O
with interrupt data
transfer to host
User Connections
All user-accessible
signals are brought
out to a 15-pin
(DT7101) or 32-pin
(DT7102) miniature
connector
Mating Connector—
DT7101: BERG
93540-150000;
DT7102: BERG
93540-3200001
Compatible
Connector Panel—
DT7101: DT783;
DT7102: DT784
