Thank you for your reply.

Yesterday I received welcomed help from NI support and my understanding of things is improving.

The problem I am facing right now is the following:

I want to send to VISA write buffer the command:

V 01 50  with the setting for the box ''normal display''

(not hexa because, when I will be sending controls from front panel, visa will only treat them as ascii characters and will convert them to hexa.) 

this command is transformed by visa write into hexa character by character =>

56 20 30 31 35 30

For the destination to understand the command, 01 and 50 must be taken as one character:

01=01hexa 

50=32hexa

How do I tell VISA write to treat 01 as one character not two and 50 as one character not two?

What kind of sign must I place between V 01 50 to signal beginning and ending of what is to be treated as one character and converted into a single hexa correspondent?

Alright: NI support to the rescue once again:

The instrument that converts numbers to ascii characters that are then transformed into hexa by visa looks like the attached picture.

So thank you Denis from NI Support Romania for this fine example.

now the source is working properly, it is understanding the requests.
