Hi,
I want comunicate with my microcontroller AT90s2313, i create a block diagram but doesn't work. I've some question
1) The CP2102 must be add in Measurement & Automation tool?
2) Is block diagram good?
P.S for example i want send the char '1' via serial by USB to UART converter and i use LABVIEW 2010
best regards
Solved! Go to Solution.

Hello bombernigno,
When do you say that it does not work, what happens exactly? Do you have an error? You do not receive the desired result?
Have you tried to execute the Basic Serial Write and Read.vi that you can find under the Examples?

Hi,
the error is "Property Node (arg 1) in VISA Configure Serial Port (Instr).vi->R_W_seriale.vi" when i run it; do you have some idea?
I think that problem is in the port configuration, becouse i don't have any device in MAX, share?

Either include the entire error message or provide the error code.
When you plug it in, if you don't see a new com port in windows device manager and in MAX, then you cannot use VISA.

Ok, I see the device in window manager but i don't see in MAX!!

Why should MAX see the device? It already shows the port.
Serial instruments don't have a standard identification command so MAX is not able to check for the device.
In GPIB there is such a command *IDN? but even there some instruments don't have that command and either send nothing, an errormsg or other info like a reading.

Do you have the CP210x drivers installed?
CP2102 will show up in MAX as a COM port.
It will show up in Device Manager as a COM port under "Ports" as well.
I have a device using a CP2102 that echoes commands sent to it, used for error rate testing. Works fine with the code...

Code sends a "1", remote device echoes it, VISA Serial reads in the reply.

Very good reply!! But I don't see any device in MAX should I reinstall LabView?
