3.2.1 Setting the time to Reset the Digital Outputs

Some users will want the capability of clearing each digital output when

the system (or PC) issues a reset signal on the PCI bus. Other users will

want to clear their digital outputs only as part of system power-on.

PCI-1736UP satisfies both these needs with jumper JP1. Depending on

the application, this capability may allow 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 mat-

ter how JP1 is set, if the power to PCI-1736UP is disconnected, the digital

output channel’s initial power-on state will be "OFF"
