1. Introduction
USB-DIO6400 board is 32-bit isolated digital input / output boards to be fully compatible with industrial
PC. It is a board that uses the USB interface Full Speed (12MB/s). USB-DIO6400 does not use a
separate external power supply because the operation takes its power from the USB cable. All of the
control functions are designed to FPGA (Field Programmable Gate Array) and it is possible to easily
upgrade to the user's needs.

[Figure 3-5] shows that digital input is isolated by photo-coupler. When applying plus(+) voltage to
“IN_COM0”, and applying minus(-) voltage to digital input(DIN0 ~ DIN7), the current is flowing through
diode in the inside to photo-coupler and an output direction transistor is applied an electric current
according to flow electric current.
There are 4 circuits as above picture to a board. In other words, there is a IN_COM signal each 8
photo-couplers, total IN_COM signals are 4 (IN_COM0 ~ IN_COM3).
If you want completely isolated circuit, it is good to use the external power better than to use the
board power.

OUTPUT can be used by selecting external power or internal power. When using an external power
supply, the J1's jumper must be disconnected before it is fully isolated.
In case of internal power supply, DC-DC converter power can be selected. When DC-DC converter is used,
J7 jumper setting (3-2 short) is done.
When using external 5V power supply, use J7 jumper setting (1-2 shots).

3. CD (Driver/Manual/API/Sample Source etc.)
4.2 Driver Installation
For USB-DIO6400 board installation at PC is as follows. There isn’t a jumper especially to set up
for board installation because USB board is a Hot Plug and Plug & Play device.
User Environment : Windows 2000 SP4 over, Windows XP SP1 over
(1) First, open the box and put the USB-DIO6400 product on safe table.
(2) The USB-DIO6400 board connects to PC through USB A-B cable.
When the cable connect, it will be install automatically drive searching at Windows Operating
system.
(3) The driver installation is as follows. The installation order is as follows, explain Windows XP
basis if there isn’t special explanation.

(4) If new hardware is found, Wizard will ask you to install the corresponding driver. For installation
of the driver, select the item “Install from a list or specific location (Advanced)”and click “Next”
as in the below figure.
After find a driver folder of the CD, press “next”button.
ex) F:\USB-DIO6400\driver
The driver folder includes a file of “usb_dio6400.inf”and “usb_dio6400.sys”that it is
necessary fir driver installation.
A warning message appears during installation here, press “Continue Anyway”button.
If the installation is completely finished, you can show below message window.
