how to configure visa to adquire dat from serial port and then converted to numeric value from a home embedded device

[geral2004]

I already stablish communication with my serial port using VISA, selecting COM1 as the resoure name.
After that, I tried to read the data from the port (as we know the data was in string format )but I need to convert the data to numeric value to hadle it (no arrays).
Another main thing is that I'm develoing a new based Embedded design and tthe info that will trhow out from the device to the PC is binary.
How can I solved the problem, and if I want to make bidirectional communication with my system how can I do it? The VISA intructions as *IDN? and so forthetc can be recognize by the external system if the COM1 port is recognized by NI Max as ADSRL1::I
NSTR1?

Hello,

For an example of bidirectional serial communication in LabVIEW, please see the shipping example LabVIEW <-> Serial.vi. This can be found from LabVIEW by going to Help >> Find Examples. From the example finder, select Hardware Input and Output >> Serial >> LabVIEW <-> Serial.vi.
Once you are able to read the string data in, you can use the VIs in the String/Number Conversion palette to convert the data to numeric format. To access these, right-click on the block diagram >> All Functions >> String >> String/Number Conversion.

Let me know if this does not help.
