PROGRAMMING THE DIO-32.PCI, CONTINUED
The following table shows common input resistors and the ranges associated with each.
Input Resistor
The turn-off voltage for all resistors is less than 1V.
Increasing the input resistor accordingly can increase the maximum input voltage. Because
socketed DIP resistors are utilized, they can easily be replaced with a different value. Sealevel can
do this, if necessary.
The input circuits are not intended for monitoring 120-volt AC circuits. In addition to being too high
a voltage for the circuits, it is dangerous to have that high a voltage on the card.
Input Ports Pin Assignments (DB-37 Female)
Inputs are interfaced via the DB-37 female connector on the supplied CA165 cable.
