I'm using v280 and reading MI memory from computer(using LabVIEW) via port1 with USB to serial. My problem is the fastest reading loop rate on the computer is 350ms, but I tried to change the baud rate to maximum value(57600) but nothing better. Has anybody can do for more faster than 350ms(I need 100ms)?

Thank you.

You will have a hard time getting a 0.1 second update serially - most of the overhead affecting communication time has to do with putting the data frames together.  I'd put an Ethernet card in the V280 and reconfigure your LabView driver to do Modbus TCP.
