The powers that be want to emulate a hight speed RS-232 connection to an instrument we are building. We don't want to poll the instrument to see if it has data. They want the instrument to have both master and slave SPI busses so that it can push data to us.
I need to find the PC hardware to do this that is compatable with LabView so I can test it. It doesn't have to be a single device. It could be two as long as one can be master and the other slave. We have the NI USB-8452 but it can't be slave.
