FCC Class A
This equipment has been tested and found to comply with
the limits for a Class A digital device, pursuant to part 15 of
the FCC Rules. These limits are designed to provide reason-
able protection against harmful interference when the
equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residen-
tial area is likely to cause interference in which case the
user is required to correct interference at his own expense.
CE
This product has passed the CE test for environmental spec-
ifications when shielded cables are used for external wiring.
We recommend the use of shielded cables. This kind of
cable is available from Advantech. Please contact your local
supplier for ordering information.

Software Installation
Hardware Installation
1. Turn off your computer and unplug the power cord
and cables.Turn off your computer before install-
ing or removing any components.
2. Remove the cover of your computer.
3. Remove the slot cover on the back panel of your
computer.
4. Touch the metal part on the surface of your computer
to neutralize any static electricity that might be in
your body.
5. Insert the PCI-1742U card into a PCI slot. Hold the
card only by its edges and carefully align it with the
slot. Insert the card firmly into place. Use of exces-
sive force must be avoided; or the card might be
damaged.
6. Fasten the bracket of the PCI card on the back panel
rail of the computer with screws.
7. Connect appropriate accessories (68-pin cable, wir-
ing terminals, etc. if necessary) to the PCI card.
8. Replace the cover of your computer chassis. Re-con-
nect the cables you removed in step 2.
9. Plug in the power cord and turn on the computer.

Signal Name ReferenceDirection Description
AI<0…15> AIGND Input Analog Input Channels 0
through 15. Each channel
pair, AI<i, i+1> (i = 0, 2,
4...14), can be configured
as either two single-ended
inputs or one differential
input.
AIGND - - Analog Input Ground. The
three ground references
(AIGND, AOGND, and
DGND) are connected
together.
AO0_REF
AO1_REF AOGND Input Analog Output Channel 0/ 1 External Reference.
AO0_OUT

AOGND - - Analog Output Ground.
The analog output volt-
ages are referenced to
these nodes. The three
ground references
(AIGND, AOGND, and
DGND) are connected
together.
DI<0..15> DGND Input Digital Input channels.
DO<0..15> DGND Output Digital Output channels.
DGND - - Digital Ground. This pin
supplies the reference for
the digital channels at the
I/O connector as well as
the +5VDC supply. The
three ground references
(AIGND, AOGND, and

together.
CNT0_CLK DGND Input Counter 0 Clock Input. The
clock input of counter 0
can be either external or
internal , as set by soft-
ware.

CNT0_GATE DGND Input Counter 0 Gate Control.
PACER_OUT DGND Output Pacer Clock Output. This
pin pulses once for each
pacer clock when turned
on. If A/D conversion is in
the pacer trigger mode,
users can use this signal
as a synchronous signal
for other applications.
TRG_GATE DGND Input A/D External Trigger Gate.
When TRG _GATE is con-
nected to DGND, it will dis-
able the external trigger
signal to input.
EXT_TRG DGND Input A/D External Trigger. This
pin is external trigger sig-
nal input for the A/D con-
version. A low-to-high
edge triggers A/D conver-
sion to start.
+12V DGND Output +12 VDC Source.
+5V DGND Output +5 VDC Source.

Analog Input Connections
Single-ended Channel Connections
The single-ended input configuration has only one sig-
nal wire for each channel, and the measured voltage
(Vm) is the voltage of the wire as referenced against the
common ground.
Figure 1: Single-ended Channel Connections
Differential Channel Connections
The differential input channels operate with two signal
wires for each channel, and the voltage difference
between both signal wires is measured. On PCI-1742U,
when all channels are configured to differential input,
up to 8 analog channels are available.
Figure 2: Differential Connection - Ground Signalt
Figure 3: Differential Connection - Floating Signal
Analog Output Connections
The PCI-1742U provides two D/A output channels,
AO0 and AO1. You may use the PCI-1742U internally-
provided precision -5V (-10V) reference to generate 0
to +5 V (+10 V) D/A output range. You may also create
a D/A output range through the external reference,
AO0_REF. The external reference input range is +/-10
V. For example, connecting with an external reference
of -7 V will generate 0 ~ +7 V D/A output.
Figure 4: Analog Output Connections
Trigger Source Connections
Internal Pacer Trigger Connection
PCI-1742U includes one 82C54 compatible program-
mable Timer/Counter chip which provides three 16-bit
counters connected to a 10 MHz clock, each designated
specifically as Counter 0, Counter 1 and Counter 2.
Counter 0 is a counter which counts events from an
input channel or outputting pulse. Counter 1 and
Counter 2 are cascaded to create a 32-bit timer for pacer
triggering. A low-to-high edge from the Counter 2 out-
put (PACER_OUT) will trigger an A/D conversion on
the PCI-1742U. At the same time, you can also use this
signal as a synchronous signal for other applications.
External Trigger Source Connection
In addition to pacer triggering, the PCI-1742U also
allows external triggering for A/D conversions. A low-
to-high edge coming from EXT_TRG will trigger an
A/D conversion on the PCI-1742U. When DGND is
connected to TRG_GATE, the external trigger function
is thereby disabled.
