VISA string ordering

[labstew]

I am trying to read data from a device using a com port and visa read write in LV.  I get back a string that is:

0000 6753 1002 0000 4008 0016 16C0 6C62 6D6A 6D28 98B4 9776 6D02 C5FF 81A4 060A

when it is supposed to be:

81ff 6a4 a 6700 1053 2 4000 8 1616 6cc0 6d62 6d6a 9828 97b4 6d76 c502 (I have to find out if this is padded with zeros or not)

I have tried different ways of arranging this  and have had little success.

Any suggestions?

The string is padded.  It is:

81FF 06A4 000A 6700 1053 0002 4000 0008 1616 6CC0 6D62 6D6A 9828 97B4 6D76 C502

Hi labstew;

this is the string you get:
0000 6753 1002 0000 4008 0016 16C0 6C62 6D6A 6D28 98B4 9776 6D02 C5FF 81A4 060A

and this the padded:
81FF 06A4 000A 6700 1053 0002 4000 0008 1616 6CC0 6D62 6D6A 9828 97B4 6D76 C502

Is this the information you need?

Yes, I need to re-arrange the string that comes from the visa read function

(0000 6753 1002 0000 4008 0016 16C0 6C62 6D6A 6D28 98B4 9776 6D02 C5FF 81A4 060A)  

so that it looks like the padded version 

(81FF 06A4 000A 6700 1053 0002 4000 0008 1616 6CC0 6D62 6D6A 9828 97B4 6D76 C502)

labstew,

Are you reading data that is being constantly transmitted from some sort of instrument?

Hi labstew,

here is a function to convert it.
