Description
The PCI-1737U is a 24-bit DI/O card with PCI bus, and provides 24 bits of parallel digital input/output. It also emulates mode 0 of the 8255 PPI chip, but the buffered circuits offer a higher driving capability than the 8255. The I/O bits are divided into three 8-bit I/O ports: A0, B0, and C0. You can configure each port as either input or output via software. The interrupt handling capability provides users the flexibility to generate interrupts to a PC. The 1-pin in the connector can output a digital signal simultaneously with the card's generating an interrupt. Other features give the PCI-1737U practical advantages in an industrial setting; when the system is hot reset or powered on, the I/O port settings and output values of PCI-1737U will be determined via switch.
