VMIC

Hi,

I am using LabVIEW 2013 on a desktop PC and a LabVIEW RT 2013 in a PXI chassis. A GE VMIC 5565 which is placed on the PXI chassis is used to communicate via VMIC interface. I use VMIC both writing and reading data. 

My problem is related with the reading data from VMIC interface. When I write a code which will write a 300 byte data in VMIC, the function is completed about 20-30 usec. However, when I want to read 300 byte from the VMIC, it is completed nearly 580 usec. Is it normal that there is a huge time difference between completion time of data read and writing vis?

Thanks
