RS232 on pxie-8100 RT


Recommended Posts



I wrote a write/read code on labview:

1. connected an external loopback to PXI  and it worked fine.

2. connected cable to my development board - didn't work at all. I checked logic voltage levels: the PXI outputs 12V Pk-Pk, while my development board outputs 5V Pk-Pk.

That must be the issue. what do you recommend?
