Hi LAVA, I am using HBM MGCplus ML01 amplifier http://www.hbm.com/en/menu/products/measurement-electronics-software/laboratory-test-stand/mgcplus/?geoip_cn=2.. I am using Hall sensor to measure the voltage values as the magnetic field varies. So i have connected output of the hall sensor to the input port of the DAQ and my daq is connected to my laptop through rs232 to USB (rs232 in daq and usb in laptop) when i inserted this cabel, it showed New hardware found and I installed the drive and i installed. In device manager i am able to see COM5... Since it is USB - RS232 cabel, will this acts as serial communication? I have attached my program, pls tell whether i shud use VISA Flush I/O buffer, else this program will work properly. Thanqserial.vi
