PCI-1753

PCI-1753 is a 96-bit digital I/O card for the PCI bus, which can be extended to 192 digital I/O channels by connecting its extension board - PCI-1753E. The card emulates mode 0 of the 8255 PPI chip, but the buffered circuits offer a higher driving capability than the 8255. The 96 I/O lines are divided into twelve 8-bit I/O ports: A0, B0, C0, A1, B1, C1, A2, B2,C2, A3, B3 and C3. You can configure each port as input or output via software.

• Up to 192 (96 + 96) TTL digital I/O lines
• Emulates mode 0 of 8255 PPI
• Buffered circuits for higher driving capacity than 8255
• Multiple-source interrupt handling
• Interrupt output pin for simultaneously triggering external devices with the interrupt
• Output status read-back
• “Pattern match” and “Change of state” interrupt functions for critical I/O monitoring
• Keeps I/O setting and digital output values when hot system reset
• Supports dry contact and wet contact
• High-density 100-pin SCSI connector
