Hi,
I'm using NI USB 6501using that i'm controlling the relays.
After wiring my hardware, once i power up all relays are by default in ON condition.
I want the DO signals of NI USB 6501should Low by default.
But my case is all DO signals are HIGH state.
I opened MAX and check the test panels there i saw it configured HIGH state.
How to change Digital Output lines as LOW ?
if you need more information to understand my questing feel free to reply me
thanks.
