I'm just trying to test a SCB-100 terminal block with a PCI-6515 card, and i have no idea where my grounds are. the manual for this device, as found on-line, doesn't explain the pin-out at all. can anyone help?
The SCB-100 is just a generic straight-through connector block assembly and the pin out is whatever the DAQ device you have connected to it. Pin 1 of the ribbon cable connector is connected to screw terminal 1, pin 2 to screw terminal 2, etc. You need to look at the pin out of the 6515 to determine which pins are your signals and grounds.
