We have an ER-8 with two 50-pin connections. One is for DIO-24 devices, one is for DIO-32 devices and we do not know which to use to connect to the SC-2040, or if we even can. Additionally, our DAQ is a PCI-MIO16-E-1 and we are currently using 14 channels for data acquistion. Is there room to run 4 channels of our ER-8? If not, can we run the 4 channels off of one input effectively making them one switch?
