Acquiring Hexadecimal data, VISA communication

$

0

Hello,

 

I would like to receive hexadecimal data sent from a Pyrometer.

I've written a very simple VI, and I used the scan from sting vi, and set it to scan a Hexadecimal integer. I 've tried too many options, commands types  and so on, but I am receiving  all the time the error :

 

----------------

 

Possible reason(s):

LabVIEW: An input parameter is invalid. For example if the input is a path, the path might contain a character not allowed by the OS such as ? or @.
=========================
Command requires GPIB Controller to be Controller-In-Charge.

 

 

-------------------------

I cannot till now find what could be the problem, since even when using the probe to check the data at every line nothing seems to be working even to set up the serial parameters or send the command...

 

Any hints will be very appreciated.

 

Thank you in advance

 

Tania
