Serial Data - String

Hello,

I have a LVDT connected to my COM1 serial port. This gives me around 7000 readings when I read the COM Port. It outputs a string like "N +0.642...." to signify the flatness of a section. The problem is that I am getting a string (Read Data) like shown in the VI and am not able to convert it into an array of readings in DBL format, which is required for further processing.

I have attached the VI that I am using.

Thanks,

James
