time delay of gps receiver in labview

[innovator81]

hello every1,

I have a superstar 2 GPS receiver..I am trying to get the gps signals into basic serial read .vi but the time delay i am using is not right..the data chunk that gets into labview is not always the entire set ....i am using time delay option in a while loop for that..is there any other way to do it....the time delay between 2 signals is 550 milliseconds as specified by the gps guyz....any help would be appreicated

How many bytes make up a complete message?? You can use a VISA property node and wait until the bytes at port value is equal to or greater than a complete message.

Why are you unable to use the VISA Bytes at Serial Port?
