GW Instek GPT-9800 Series Drivers?

[rolfk]

In NI-MAX try to do a Refresh. Menu View->Refresh or F5.

As long as the serial port is not visible in NI-MAX you can try whatever you like but it won't work in LabVIEW either.

Also you are saying the serial port is visible in the Device Manager. As what and do you see any question mark or other symbol on that device entry?

Hi,

There is no error or any highlight. The device comport name is very clear in device manager.

Hi,

This is newly created vi.

Below is the error.

Under NI-Max

I am connected USB cable from Instrument to PC.

I don't know why it is not detecting in NI-MAX software.

You (re)post quite a bit of pictures, but as far as the Device Manager goes, all we have is your word that your port is visible in there. Why not post a pic of that too?

As long as the port is not visible in NI-MAX, you can jump high, low, forward and backward, but LabVIEW will not be able to access it!!! Did you do F5 or View->Refresh in NI-MAX?

First thing I would check is to ensure you have NI-Serial installed.  You should see it in NI-MAX if you expand the Software section.

Hi,

I installed again NI-Visa software and after that it detected. 

I have 4 different type of test Vi's. I want to create common program. Steps of program as below.

1) When I click on Start, comport address should read from config file. Config.ini (From path)

2) Once initialization is ok, Operator need to enter the name.

4) Select the model type in LabVIEW as per data base file. Global_Data.xls. From define path.

5) As per define test parameter, it should start testing. Example Global_Data.xls, 

variable_name

Part/name

Voltage_In_Kv

Maximum_Current_Is_Set_At_mA

Test_Time

RAMP_Second_Testing_Time

6) Once test is complete (pass/Fail) , the test result needs to write into excel. (18-07-2024 example).

Please advice.

Hey there,

You'll need to install the GPT-9800 USB driver first before it can enumerate as a serial port and be visible in both Device Manager and NI-MAX. You can download it here

Once that's installed, you should see it available. If you still don't, you can try physically cycling the USB connection. 

You can try then a *IDN? in NI-MAX to see if you get simple communication. 

Note that you may also need to configure the port on the Hipot front panel to switch from RS232 to USB. Default baud rate in USB mode for this series device is 115,200.

Best of Luck.

Hello All,

This is VI, i want to add user information such User name or operator name, and after testing complete the data needs to be captured into excel/csv file.

Such as date & time, operator name, Model name/Number, DCV voltage, Timer, Rise time and results (pass/fail). Advice 

[NIquist]

If you have the hardware communicating and you're ready to write the top-level program, the pattern is obvious.  State Machine.

You want to run a program that:

Initializes hardware

Loads configuration file

Setup the hardware and variables from the config

Idle while waiting for operator choice

Execute one of several tests

Display data

Stores data

Shutdown hardware

Quit program

Maybe have and ERROR state to jump to if there's a problem.

Search for LabVIEW state machine tutorial and check out the built-in template.  This is the most popular coding pattern and is very important to learn.
