Problem: What is size of the pull-up resistor in the NI 6703/6704 analog output devices? Solution: The NI 6703/6704 devices do not have pull-up or pull-down resistors. An FPGA drives the digital lines instead of the STC Chipset. The STC Chipset uses a pull-up resistor, but the NI 6703/6704 devices do not. However, both devices power on their digital lines to a high-impedance state, so if you want a pull-up or pull-down resistor on the digital lines, you can wire one externally.
