PCI-1762 User Manual 10
the system (or PC) issues a reset signal on the PCI bus. Some users
will want to clear their relays only as part of system power-on.
The PCI-1762 satisfies both these needs by providing jumper JP2.
Depending on the application, this capability may allow relay 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-1762 is disconnected, the
relay initial power-on state will be “OFF” (NC or NO, depending on the
user’s settings).
