Page 7: Analog Input
AOGND Analog Input The NI USB-7845R OEM device provides connections for eight AI channels. Each channel has an AI+ pin, AI- pin, and AIGND pin to which you can connect both single-ended or differential voltage signals. Use the AISENSE pin to connect non-referenced single-ended signals. - Page 8 NI USB-7845R OEM Connecting Differential Voltage Signals You can connect grounded or floating differential signal sources to the NI USB-7845R OEM device. Connect the positive voltage signal to the AI+ and the negative voltage signal to AI-. To connect grounded differential signals to the NI USB-7845R OEM device, you must also connect the signal reference to AI GND.
