I am new to using the NI-PCI 8532 card. I am trying to attach a solenoid valve manifold to this card. On the PCI 8532 card pinout, pin 2 is called "V- (CAN reference ground)". I am confused as to why this pin is called V- but the description is that it is the reference ground. Is there a voltage associated with this pin? What does this pin do?
The solenoid manifold pinout is as follows
2. V+ (power supply)
3. V- (power supply)
Do I connect the V- of the solenoid manifold to the V- (Pin2) on the PCI card? (The pinout for the card is attached).
