I have started working on a development system that has had a NI PCIe-6536B digital I/O card installed. Also installed is the NI-DAQmx 16.0 driver software. However, I am unable to find my NI PCIe-6536B card under Windows 7 or Windows 10 (both x64, both with NI-DAQmx 16.0) in the Device Manager: nothing jumps out at me as being that card. On Windows 10 (x32, with both Traditional NI-DAQ and NI-DAQmx 16.0 installed) I see a device called "PCI Data Acquisition and Signal Processing Controller" and I can even install the PCIe-6536B driver for it and see it in NI-MAX, but it doesn't work. NI-MAX shows error -50150 / Software is in a bad state, and reset/self test/configure all give the same error.
From the manual it sounds like the card was supposed to have auto-detected in Windows after installation of the physical media. (a) How should the card show up in Device Manager if appropriate drivers haven't been associated with it yet? (b) Could what I'm seen be caused by an incompatibility between my card and my system, damage to the card or improper installation, etc.? For what it's worth: there is a solid lit green LED on the card.
