82C55 based
General Description
The PCI-DIO24/LP is a 24-bit, logic level digital I/O board for low profile/half height PCI bus compatible computers. The board is compatible with both 5 Volt and 3.3 Volt PCI buses.
The PCI-DIO24/LP is based on the industry standard 82C55 chip, and the 82C55 I/O pins are brought directly to the board's I/O connector. The 82C55 is a powerful 24 bit chip and functions as two 8-bit ports, (Ports A and B) and a third 8-bit port (Port C) that may be further divided into two 4-bit ports (Port C-HI and C-LO). The CMOS outputs of the 82C55 are suitable for driving a wide array of logic devices, though the chips ±2.5 mA drive capability may not be enough in some applications.
Connections to the PCI-DIO24/LP are made through a DB68, ultra-micro SCSI type connector. The board uses the C68MMS-x series cable and the CIO-MINI68 screw terminal board.
The PCI-DIO24/LP is completely plug-and-play. There are no switches, or jumpers on the board. All board addresses, interrupt channels etc. are set by your computers plug-and-play software.
