About the Product
This product is a USB2.0-compatible terminal that allows your PC to expand the bidirectional I/O
functionality of digital signals. The terminal comes with 24 channels of non-insulated LVTTL-level
inputs/outputs. Inputs and outputs can be switched in blocks of eight by software. Its compact
appearance makes it suitable for PC a pplicati on. In additi on, no e xternal p ower su pply is r equired , as the
terminal operates on the USB bus power.
Windows driver is bundled with this product.
Possible to be used as a data recording device for LabVIEW, with dedicated libraries.
Features
- Non-insulated LVTTL-level inputs/outputs (Positive)
The product is provided with 24 non-insulated LVTTL-level I/O ports with a response speed of 200 nsec
(positive logic). This allows you to use a total of up to 24 channels of I/O digital signals in three sets of
eight.
- Compatible to USB1.1/USB2.0 and not necessary to power t his prod uct exter nally as t he bus po wer is
used.
Compatible to USB1.1/USB2.0 and capable to achieve high speed transfer at HighSpeed (480 Mbps).
Not necessary to power this product externally as the bus power of USB is used.

3. External Connection
Cable connection
When connecting the product to an external device, you can use the supplied connector plug.
For wiring, strip off approximately 9 - 10mm of the covered part of a wire rod and then insert it to the
opening. After the insertion, secure the wire rod with screws.
Compatible wires are AWG 28 - 16.
CAUTION
Removing the connector plug by grasping the cable can break the wire.

3. External Connection
Connecting I/O Signals
As I/O signals are LVTTL (3.3V) level signals, the total cable length should be within 1.5 m.
The input is provided with an input protective resistor (33Ω).
GND is common to all I/O pins.
Figure 3.5. Input Circuit
Figure 3.6. Output Circuit
If the signal source is affected by noise or distant from the produc t, the produ ct may fail to input ac curate
data depending on the connection.
I/O signals are LVTTL-level active high signals. When the external input signal is LVTTL level, the
Low level represents logic 0 and the High level represents logic 1. When the program outputs 0 and 1,
the product outputs the Low and High level signals, respectively.
