VISA plp tti power supply

[vince.th]

 Hi everyone, 

I have a reception problem of data of my power supply TTi pl303-P. 

I tested the communication via Ni MAX, and no pb, it works properly when i send *IDN? it answer me right. 

But as soon as i want do the same with a VI, there is no display in the read buffer...

here my code

i tested without "\n", with an open serial VI, change the byte count, ... No display while i haven't message error

I even did a test with the instrument assistant and it worked...

Please help, thanks in advance. 

EDIT: i use the V14.0

What error is returned?

Add one of the Error Handlers to the end of your little VI and tell us what it says.

Hi Arnaud_G

I ran it : http://prntscr.com/atnbph 

ASRL 5 is the port COM where my unit is connected.

I finally choose the facility by using an USB/Ethernet adaptator ...

Thx!
