Features
Bus isolated high precision analog input 8 channels / output 2 channels,
each 4 channels for digital I/O, counter 1 channel
This product has analog input (10µsec / channel [100KSPS], 16-bit, 8
channels), analog output (10µsec [100KSPS], 16-bit, 2 channels),
analog I/O control signal (Isolation TTL level 6 channels), digital I/O (4
channels each for Isolation TTL level), counter (32-bit, Isolation TTL
level 1 channel).
Functions and connectors are compatible with PCI compatible board
ADAI16-8/2(LPCI)L
The functions same with PCI compatible board ADAI16-8/2(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.
Bus isolation between PC and external I/O signals by a digital isolator
Isolation between PC and external I/O circuit by a digital isolator
improves noise tolerance.
The start/end of sampling can be controlled by software, comparison of
conversion data, an external trigger, etc.
You can select from software, comparison of conversion data or an
external trigger to control the start of sampling. You can select from
completion of sampling for a specified number of sessions, comparison
of conversion data, an external trigger or software to control the end of
sampling. The sampling cycle can be selected from the internal clock
or an external clock.
Equipped with buffer memory (1K data) that can be used in the FIFO
or RING format
The analog input block contains buffer memory (1K data) that can be
used in the FIFO or RING format. This allows for background analog
I/O that does not depend on the operation status of the software or PC.
Bus isolation between PC and external analog output circuit by a digital
isolator
Isolation between PC and external analog output circuit by a digital
isolator improves noise performance.
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 analog output 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
A digital 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)
Software-based calibration function
Calibration 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.
Data logger software, Windows/Linux compatible driver libraries are
attached.
Using the bundled data logger software “C-LOGGER” allows you to
display recorded signal data in graphs, save files without any special
program. In addition, the driver library API-PAC(W32) which makes it
possible to create applications of Windows/Linux 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.

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.
Analog Input Signal Connection
Single-ended Input
The following figure shows an example of flat cable connection.
Connect separate signal and ground wires for each analog input
channel on CN1.
Single-ended Input Connection (Flat Cable)
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.
Single-ended Input Connection (Shield Cable)
*1 The number of channels depends on each board. The AIO-160802LI-PE has eight channels.
CAUTION
- If the signal source contains over 1MHz signals, the signal may effect the cross-talk noise
between channels.
- If the board and the signal source receive noise or the distance between the board and the
signal source is too long, data may not be input properly.
- An input analog signal should not exceed the maximum input voltage (relate to the board
analog ground). If it exceeds the maximum voltage, the board may be damaged.
- Connect all the unused analog input channels to analog ground.
- The signal connected to an input pin may fluctuate after switching of the multiplexer. If this
occurs, shorten the cable between the signal source and the analog input pin or insert a high-
speed amplifier as a buffer between the two to reduce the fluctuation.
- Analog ground of CN1 is isolated from the ground in the PC.
Analog Output Signal Connection
This section shows how to connect the analog output signal by using a
flat cable or a shielded cable.

and connect the shielding to ground.

*2 The number of channels depends on each board. The AIO-160802LI-PE has two channels.
CAUTION
- When the power supply is turned on, the output voltage of all channels becomes 0V.
- 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.
- 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.
- Analog ground of CN1 is isolated from the ground in the PC.
Digital I/O signals, Counter signals and Control
signals Connection
The following sections show examples of how to connect digital I/O
signals, counter I/O signals, and other control I/O signals (external
trigger input signals, sampling clock input signals, etc.).
All the digital I/O signals and control signals are TTL level signals.

Digital Output Connection
About the counter input control signal
Counter Gate Control Input (refer to the chapter 3 Connector Pin
Assignment) acts as an input that validate or invalidate the input of an
external clock for the counter. This function enables the control of an
external clock input for the counter. The external clock for the counter
is effective when input is "High", and invalid when input is "Low". If
unconnected, it is a pull-up in the board (card) and remains "High".
Therefore the external clock for the counter is effective when the
counter gate control input 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.
- Do not connect a digital output signal to any other d igital output, either on the board or on an
external device, as this may cause a fault on the board.
- Analog ground of CN1 is isolated from the ground in the PC.
