Hex String to Remote TCPIP Server

[DaveVoigts]

Hi.

I am in the final stages of a project. The aim is to take a GPRMC ASCII string from my GPS enabled radio, convert it to HEX and send to my remote GPS tracking server.

The remote server is from a third party and only accepts HEX. I am new to LabView but have successfully got to the stage of converting the string to HEX. Please find below an example

HEX:

32302C3031303930373030303030302C31332C30322C31382C31362E3831363636372C39362E3136363636372C313330362C532C002A32380D0A0D0A

ASCII:

20,010907000000,13,02,18,16.816667,96.166667,1306,S,28

I have spent the last few days trawling the internet and support forums but have not been able to find (and not sure if its possible) how to send the HEX over a TCPIP: PORT  connection. If anyone could kindly point me in the right direction while I still have hair left it would be greatly appreciated.

Regards

Hi Dave,

how to send the HEX over a TCPIP: PORT  connection.

TCP functions accept strings for data input.

I guess your "HEX" data also is a plain string?

[DaveVoigts]

Hi GerdW.

Yes the HEX is currently a plain string.

When you say "hex", what exactly do you mean?

If you are just referring to the raw data, then it sounds like you are just a little confused by the display on the indicator.  For example, an ASCII "2" is represented by a byte with a value of 0x32.  So your data is the same at the byte level.

Hi Crossrulz

I am taking an "Array To Spreadsheet String" and passing it through a "Number to Hexadecimal String"

Output of "Array to SpreadSheet String" =

20,010907000000,13,02,18,16.816667,96.166667,1306,S,28

Output of "Number to Hexadecimal String" =

32302C3031303930373030303030302C31332C30322C31382C31362E3831363636372C39362E3136363636372C313330362C532C002A32380D0A0D0A

I hope this helps some. I ave only been using LabVIEW for about a week.

ArrayToSpreadsheetString outputs a string, NumberToHexString expects a numeric value at its input.

How did you connect those two functions???

Hi GerdW

The project has been a learning process and fun but have probably scurried up a number of wrong paths. However the end result appears to be near my goal. Happy for direction change if needed.

I used the following jpg to convert the CSV to HEX (If my terms are correct).

Hi Dave,

I used the following jpg to convert the CSV to HEX (If my terms are correct).

So you used some more function than you have described earlier.

See the effect of providing more information?

Some changes to your code:

(You really should learn to clean up your block diagrams!)

So is your problem solved?

Is your GPS tracker receiving the data it needs/expects?

[DaveVoigts]

Noted on the tidy up. It is my plan once I have finished the continuous changes to make it good.

I now need to send that information over a TCP connection to my GPS server located offshore. This is my final headache.

Hi Dave,

looks quite easy:

(LabVIEW comes with a huge library of example VIs. There are also examples for those TCP functions…)
