Collecting HEX data from a GPS receiver interface box

[caunchman]

  We are currently running a passive tap box inline with a GPS receiver.   I am looking to use LABVIEW to collect and scale the data the box is feeding out.  It's output is a RS232 serial connection.  Will I need a GPIB to handle this data before aquiring it in LABVIEW? I am more fimiliar on the analog collection while using multiDAQ hardware.  Looking to get this to see my options using LABVIEW.

Thanks,

Chris

GPIB and RS-232 are completely different. However, you use the same functions in LabVIEW to communicate with both types of devices. This is called VISA. There are a couple of shipping examples that use VISA to communicate to serial port devices. Open the example finder, go to the search tab and enter serial.

Hi caunchman,

To add to what Dennis said, try the Basic Serial Write and Read VI to get you started. To find it, open the example finder and under the browse tab, navigate to Hardware Input and Output>>Serial.
The link below also has some good information on getting started with Serial sommunication:

Hope it helps. Thanks
