Setting the time to reset the digital outputs and the counter
value
Some users will want the capability of clearing each counter and the
isolated digital output when the system (or PC) issues a reset signal on
the PCI bus. Some users will want to clear their counter and digital
output only as part of system power-on.
The PCI-1784 satisfies both these needs by providing jumper JP2.
Depending on the application, this capability may allow counter value
and the isolated digital outputs to be "OFF" without requiring a
complete shutdown of processes controlled by the card.
Complete loss of power to the chip clears the chip memory. Thus, no
matter how JP2 is set, if the power to the PCI-1784 is disconnected, the
counter value and the isolated digital output initial power-on state will
be "OFF".
