National Instruments USB-6356 Multifunction I/O Device

The NI USB-6356 (Part Numbers: 781444-01, 781444-02, 782261-01) is used for data acquisition. Each terminal of the I/O channels is programmable. Each one of them can be programmed as an input. Each one of them can also be programmed as an output. The digital I/O channels of the USB-6356 provide input voltage protection. The magnitude of this voltage protection is ±20 V on up to 2 pins. The typical magnitude of its resistor is 50 kΩ. The minimum value of the resistor of digital I/O channels is 20 kΩ.

The USB-6356 NI device utilizes Port 0 for the waveform feature. Port 0 is the only terminal used for this purpose. The sample magnitude of measurements is 8-bits. The magnitude of waveform generation is 2,047 samples. The magnitude of waveform acquisition is 255 samples. The waveform characteristics of this USB device are system dependent. These are also dependent on the bus activity. The streaming value from memory is 0 MHz to 10 MHz for the USB-6356.

The NI USB-6356 X Series DAQ Device has 2.2 V as the minimum value of input high voltage. The maximum value of input high voltage is 5.25 Volts. The minimum value for input low voltage is 0 V. The maximum value for input low voltage is 0.8 V. The output high current for P0 is -24 mA maximum. The output high current for PFI/P1/P2 is -16 mA maximum. The value of the positive threshold is 2.2 V maximum. The value of the negative threshold is 0.8 minimum.
