Hi Akim_10,
This part of the Forum is in English; please refer to this part of the Forum

Concerning your question:
When entering
the VISA resource name input for the VISA Open function or the VISA Serial
Config function, do not use the standard port names (COM1, COM2, LPT1, etc.).
Instead use the VISA resource name for these ports: COM1 is ASRL1::INSTR, etc.
For example:
Place a VISA Open
function on your block diagram and use the wiring tool to right-click on
the VISA resource name input.
Select Create » Control
from the right-click menu.
Go to the front panel
and right-click on the newly created control.
Select Allow Undefined
Names from the right-click menu (if it isn't already selected).
Enter the VISA Resource
Name for your port. The name should look something like
"ASRL1::INSTR". Note: This name can be found in the Measurement
& Automation Explorer (MAX) under Devices and Interfaces » Ports
(Serial & Parallel). For example, click on COM1 and you will see its
VISA Resource Name in the right-hand portion of the MAX window.
