1. Before Using the Product
AIO-121602LN-USB, AIO-120802LN-USB 1
1. Before Using the Product
This chapter provides information you should know before using the product.
About the Unit
This product is a USB2.0-compliant analog I/O unit that extends the analog I/O function of USB port of
PCs.
Compact design not restricting installation location (188.0(W) x 78.0(D) × 30.5(H)) makes it easy to
install the product within the panel or device using DIN rail mounting jigs, or on the floor or wall.
Windows driver library is supplied. Possible to be used as a data recording device for LabVIEW, with
dedicated libraries.
Features
Multi-function
Analog I/O can be implemented in a compact system. The series consists of two different models from
which you can select the best model to suit your application.
The < AIO-121602LN-USB > contains the analog input (12bit, 16ch), analog output (12bit, 2ch).
The < AIO-120802LN-USB > contains the analog input (12bit, 8ch), analog output (12bit, 2ch).
All two models include bi-directional digital inputs / outputs (16points, TTL level) and a counter (32bit
1ch, TTL level). You can select the input/output by the application software in eight signals units.
Analog I/O can be synchronized with an internal timer or external clock.
Analog I/O can both be performed at fixed time intervals and synchronized with an external signal.
- Digital filter function to prevent wrong recognition of external signal chattering is provided.
This product has analog input / output control signal, digital input signal and digital filter function to
prevent it from chattering in counter input signal. (Excluding external clock input signal, counter gate
signal)
Buffer memory available for background processing independent of software
The boards include buffer memory (1K Word each for analog input and output) which can be used in
either FIFO or ring format. This allows analog I/O to be performed independently of the operating state
of the PC or software.
Software-based calibration function
Calibration of analog input/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.
- Compact design not restricting installation location (188.0(W) x 78.0(D) x 30.5(H))
Compact design of 188.0(W) × 78.0(D) × 30.5(H) does not require special installation location.
- Compatible to USB1.1/USB2.0
Compatible to USB1.1/USB2.0 and capable to achieve high speed transfer at HighSpeed (480 Mbps).

1. Before Using the Product
2AIO-121602LN-USB, AIO-120802LN-USB
- Diverse installations such as screw fastening, magnet, DIN rail are possible

Supporting the data logger software [C-LOGGER] that enables the graph display of recorded signal
data, file saving, and dynamic transfer to the spreadsheet software program “Excel”.
Plug-ins for the dedicated libraries, the board also supports MATLAB and LabVIEW.
We offer a dedicated library [ML-DAQ], which allows you to use this product on MATLAB by The
MathWorks as well as another dedicated library [VI-DAQ], which allows you to use the product on
LabVIEW.
These dedicated libraries are available, free of charge (downloadable), on our web site.
