AO-1608L-LPE 1
100KSPS 16-bit 8ch Analog Output Board
for PCI Express(Low Profile)
AO-1608L-LPE
*Specifications, color and design of the products are subject to
change without notice.
This product is a Low Profile PCI Express bus-compliant
interface board used to provide an analog signal output function
on a PC.
This product is multifunction type with 16-bit analog output 8
channels, digital I/O and counter function.
This product carries buffer memory for 1K of data, allowing
sampling to be performed in a variety of trigger / clock conditions.
Windows/Linux driver is bundled with this product.
Possible to be used as a data recording device for MATLAB and
LabVIEW, with dedicated libraries.
High precision analog output 8 channels, each 4 channels
for digital I/O, counter 1 channel
This product has analog output (10sec, 16-bit, 8 channels),
analog output control signal (LVTTL level 3 channels), digital I/O
(each 4 channels for LVTTL level), counter (32-bit, LVTTL level 1
channel).
The start/end of sampling can be controlled by software, an
external trigger, etc.
You can select from software, an external trigger to control the
start of sampling. You can select from completion of sampling for
a specified number of sessions, an external trigger or software to
control forcibly the end of sampling. The sampling cycle can be
selected from the internal clock or an external clock.
Safety design to adjust output voltage to 0V when power
supply is turned on
To prevent the unstable voltage and the connected device of D/A
converter from fault and malfunctions when the power supply is
turned on, the circuit is designed to adjust output voltage of the
analog output to 0V.
Equipped with buffer memory (1K data) that can be used in
the FIFO or RING format
The block contains buffer memory (1K data) that can be used in
the FIFO or RING format. This allows for background analog
output that does not depend on the operation status of the
software or PC.
Digital filter function included to prevent misdetection due to
chattering on external signals
Adigital filter is included to prevent misdetection due to chattering
on the control signal (external trigger input signal, sampling clock
input signal, etc.), digital input signal and counter input signal.
(Except from external clock input signal and counter gate signal)
Functions and connectors are compatible with PCI
compatible board DA16-8(LPCI)L
The functions same with PCI compatible board DA16-8(LPCI)L
are provided.
In addition, as there is compatibility in terms of connector shape
and pin assignments, it is easy to migrate from the existing
system.
Support for both of low-profile and standard PCI slots
(interchangeable with a bundled bracket)
This product has each bracket for both low-profile size slot and
standard size slot. If you wish to mount this product in a
standard size slot, replace this with the standard size bracket.
Software-based calibration function
Calibration of analog output can be all performed by software.
Apart from the adjustment information prepared before shipment,
additional adjustment information can be stored according to the
use environment.
Windows/Linux compatible driver libraries are attached.
Using the attached driver libraryAPI-PAC(W32) makes it possible
to create applications ofWindow/Linux. In addition, a diagnostic
program by which the operations of hardware can be checked is
provided.
MATLAB and LabVIEW is supported by a plug-in of
dedicated library VI-DAQ.
Using the dedicated library MATLAB and VI-DAQ makes it
possible to make a LabVIEW application.

N.C.
No connection to this pin.
CAUTION
Do not connect any of the outputs and power outputs to the
analog or digital ground. Neither connect outputs to each
other. Doing either can result in a fault.
If analog and digital ground are shorted together, noise on
the digital signals may affect the analog signals.
Accordingly, analog and digital ground should be separated.
Leave "Reserved" pins unconnected. Connecting these
pins may cause a fault in the board.
This section shows how to connect the analog output signal by
using a flat cable or a shielded cable.
The following figure shows an example of flat cable connection.
Connect the signal source and ground to the CN1 analog output.

BOARD CN1 Cable Target
The following figure shows an example of shield cable
connection. Use shielded cable if the distance between the
signal source and board is long or if you want to provide better
protection from noise. For each analog input channel on CN1,
connect the core wire to the signal line and connect the shielding
to ground.

BOARD CN1 Target
*1 The number of channels depends on each board.
The AO-1608L-LPE has 8 channels.
CAUTION
When the power supply is turned on, the output voltage of all
channels becomes 0 V.
If the board or the connected wire receives noise, or the
distance between the board and the target is long, data may
not be outputted properly.
For analog output signal, the current capacity is ±3mA (Max.).
Check the specification of the connected device before
connecting the board.
Do not short the analog output signal to analog ground,
digital ground, and/or power line. Doing so may damage
the board.
Do not connect an analog output signal to any other analog
output, either on the board or on an external device, as this
may cause a fault on the board.

About the counter input signal control
Counter Gate Control Input (see page 3, Connector Pin
Assignment”) allows the input of the external clock for the counter
to be enabled and disabled. This function can be used to
control the input of the external clock for the counter. When the
input level is “High”, the input of the external clock for the counter
is enabled. It is, on the other hand, disabled, when the input
level is “Low”. Note that when it is not connected, the input level
is set to “High” as the board (card) pins are pulled up. Therefore,
the input of the external clock for the counter is enabled when it is
not connected.
CAUTION
Do not short the output signals to analog ground, digital
ground, and/or power line. Doing so may damage the
board.
