New to Labview need help Reading from GPS receiver

[adrianoqq]

Hi,

I am new to labview, i want to ask about how to acquire GPS coordinates through a GPS receiver such as (GPS Receiver -GP20U7 (this can be changed if there are better options)). Is it possible to do it through a NI USB 6211 DAQ and Labview? how will the connection work?

Thanks for the help.

Jodanjj,

There are a few different connections that will need to be made. First, you will have to look into your GPS receiver. I am not very familiar with the receiver itself, but you will need to match up its outputs with the inputs on the NI USB-6211. The manual or specification sheet for the GPS receiver should give you more information on how to wire it. Here is a link to the manual for the USB-6211 which includes the pinouts: https://www.ni.com/docs/en-US/bundle/usb-621x-manual/resource/usb-621x-manual.pdf .

You will also need to connect your DAQ device to LabVIEW, which you can do by downloading the DAQmx driver from our downloads page that works with your device and your version of LabVIEW. Here is some very general documentation on getting started with DAQmx: https://www.ni.com/en/support/documentation/supplemental/06/getting-started-with-ni-daqmx--main-page.... We always recommend starting from an example and building on that!

Ultimately, it really depends on your application and on your GPS receiver device.

I hope that helps!

It has a serial port so why don't you use that?

Sorry i am quite new to this field and i am not quite sure how to connect the 3 pin from the GPS module. I researched about the RS232 to USB adapter. Is there a better option to connect to the computer using USB and using VISA in labview to read the the data, or is there a way to read the output from the NI daq??

hi,

i just found this USB to Serial cable

ADAFRUIT INDUSTRIES  954  USB-TO-TTL SERIAL CABLE

willl this work it i connect the pins and read from VISA?

I don't know.

First check the manual on the voltages of the GPS receiver and be real sure.

I believe adafruit is not bad, but maybe you need 3.3 volt instead of ttl
