This section is applicable to National Instruments card PC-DIO96 and PC-DIO96PnP. The cards are identical except for the Plug-andPlay capability of the PC-DIO96PnP. For the sake of this help file and the I/O driver itself, references to PC-DIO96 shall apply to the PC-DIO96PnP as well.
The PC-DIO96 is a member of the National Instruments PC Series of I/O channel expansion cards for ISA computers. These cards are designed for high-performance data acquisition and control for many types of applications. The PC-DIO96 is a 96 bit, parallel, digital I/O interface for ISA computers. Four 82C55A programmable peripheral interface (PPI) chips control the 96 bits of digital I/O. The 82C55A can operate in either input or output mode. All digital I/O communication is through a standard , 100 pin, male connector.
The V+/National Instruments I/O Driver provides the interface software between V+ and the PC-DIO96. The user is able to configure the PC-DIO96 in a number of input/output combinations and have those inputs and outputs automatically available as I/O ports in a V+ design.
Port Naming Convention
The default port names for the PC-DIO96 align with the naming convention used in the PC-DIO96/PnP User Manual. The following illustration shows the pinout of the 100 pin external connector of the card. The names that are assigned to each pin are the same names that will be assigned to the I/O ports on the V+ design worksheet. For example, the digital line connected to pin 15 of the 100 pin connector will correspond to the I/O port labeled "APC0". If you are using the breakout cable assembly, refer to the pinout diagram for the PC-DIO96 cable assembly.
