[luli8697]

I bought a NI 9381 device and I thought it is 2 line standard 15 pin RS485/422 serial interface wich can connect to PC. But when I get the devic I find that 3 line 15 pin interface. I just wnat to know is that still standard pin map as 2 line interface for each pin?

I think I made a mistake. I thought NI 9381 can be operating independently, but it looks it mout use in CompactRIO system. right?
