3. Software Installation
3.1
Application software and USB driver installation
Insert the CD to PC and run FTezDAQ-setup-2.0.exe. The following window will pop up.
Select the folder which you want to install.
Click “Next”, then select “Install this driver software anyway”
4
After the driver installation completed, click “Finish” and close the following windows.
The USB driver and application software has been installed.
**Note: For DAQ-1X11 and DAQ-0311A, PC may show the following message,
5
Please ignore this error message and close this window.
3.2
Windows Vista/XP/2000 USB driver installation
For Windows® Vista/XP/2000 operation system, sometimes, when first time the device is connected to
PC USB port, PC will show “Found New Hardware”.
Select “No, not this time”, then click “Next”.
Select “Install the software automatically”, then”Next”
6
Select “Continue Anyway”
Click “Finish” to complete the driver installation.
Sometimes, PC will show “Found New Hardware” again, just repeat above steps.

4.3
Device Type Selection
Pull down the Device Type selection window and select the device type which user purchased.
9
After select the Device Type, the dedicate window with functions which that device has will show up.
The detailed functions for each device will describe later.
4.4
Analog Input Setting and Display
From “Settings””Range” window, user can select the analog input voltage ranges.
Check “Select” to select this channel will be measured. Input the Sampling Rate to set the data sampling
rate for this channel. ( ** Max sampling rate is difference for different device. The max value of
Sampling Rate is limited by the device).
In the “Display” section, check “Graph”, will display the test result plot.
10
In the Y-axis window, if select “Voltage”, the window will display the plot for input voltage vs time.
If select “Function Y”, the window will display the plot with the function of input voltage, user can
input the coefficients base on the measured voltage to display the physical characters.
4.5
Digital Input Setting and Display
Digital input channel setting and display are similar as analog, just set the sampling rate and check
“select” to select the channel which will be measured.
4.6
Analog Output Channels Setting
The analog output channel has different output mode:
11
It can output user defined voltage at “Voltage Value” mode. It also can output fixed amplitude Sin,
Triangle and Sawtooth waveform, the frequency can be changed, normally the max frequency is 1KHz.
4.7
Counters Input
Some device has digital input counters, they count the input voltage falling edges.
4.8
Digital Output Channels Settings
Digital output channels can output TTL level digital signal or PWM waveform.
When select output mode as “Status Value”, it will output the TTL signal High or Low. When select
output mode as PWM Wave, it will output PWM waveform, user can input the frequency and duty ratio.
4.9
Data Acquisition Starting Methods
There are several ways to start data acquisition.
The “Start Trigger” can be:

Manual

Raising Edge

Falling Edge
12
Except “Manual”, the trigger signal comes from Digital Input Channel 1.
The “Stop Trigger” can be

Manual

Raising Edge

Falling Edge

Time Out
If choose stop trigger mode as “Time Out”, user can define the test duration.
If choose the Start Trigger and Stop Trigger are both Manual, when click “Start” icon
the test; when click “Stop” icon
will stop the test.
13
, will start
If choose the Start Trigger is not Manual, after click “Start” icon
trigger signal occurs.
, the test will not start until the
4.10 Data Graph Print
After the testing, if the “Graph” has been checked, the graph can be printed by click “Print”.
4.11 Timer
User can use Digital Input Channel 1 as Start and Stop Trigger to measure external event timing.
