Hello,We are trying to communicate to a ROD-4 (instrument) by using an rs232 link. We have a program from rod-4 on pc and this communicates with the instrument(--> rs232link is OK I suppose) but we can't program everything we want. Therefore we will use Labview to communicate with the instrument(Rod-4). We have made a VI to communicate with the ROD-4 but it doesn't work. Do you want to check the VI I have made to communicate by rs232. Check also the rod-4 maual.pdf on pg 8 and 9, there is standing which program language the rod-4 knows (ascii protocol). The machine(rod-4) answers in the string read with:'' ?\n\r ''what dus this means? (Using win98se with Labview 5.1)Thanks.

LabVIEW

I intend to buy a tachometer with a RS232 interface. Should I connect it with a serial port or a 6025E Daq card?
