6. PWM Output: PCIE-1760 can generate PWM (pulse width modulation) signal
which you can configure its logic high time and logic low time as figure below.
Digital Filter for Digital Input Channels
The PCIE-1760 includes a programmable digital filter on each digital input channel to
eliminate the unexpected signal or noise from the card's inputs. When the digital filter
is enabled, the state of the corresponding input channel will not update immediately
until one high/low signal has lasted for a period which is programmed by the user.
Interrupt Function Ensures Faster System Response
The PCIE-1760 provides a “Pattern Match” interrupt function for the digital input
channels. It monitors the state of some or all of the input channels and compares it
with a pre-set pattern. When the received state matches the pre-set pattern, PCIE-
1760 will generate an interrupt signal to the system. The “Change of Input State”
interrupt function means PCIE-1760 monitors the state of the input channels. When
any input changes its state, the card interrupts the system to handle this event.
Note! For detailed specifications of the PCIE-1760, refer to Appendix A, Spec-
ifications.
