     Overview and Applications

     NI 6503 devices are 24-bit parallel DIO interfaces for PCI, PCMCIA, and ISA. NI 6508 devices offer 96-bit parallel DIO interfaces for PCI, PXI, and ISA. All NI 650x devices are designed for 5 V TTL/CMOS I/O signals.

     Digital I/O Connector

     Digital connectors for the NI 650x devices are described in Table 2. The eight bits in Port A of each PPI are at xPA7 through xPA0 on the digital I/O connector where x represents which PPI is being used. Ports B and C are at xPB7 through xPB0 and xPC7 through xPC0, respectively. Each port is programmed to be input or output. Power from the computer I/O channel is also available on the DIO connector. See page 381 to learn more about connectivity solutions, including direct connectors, electromechanical relay devices, and other signal conditioning solutions.

     Hardware

     82C55 Parallel Port Interfaces

     NI 650x devices use 82C55 Parallel Port Interfaces (PPIs). NI 6503 devices contain one PPI, and the NI 6508 devices contain four. Each PPI controls 24 bits of DIO and has three 8-bit ports (A, B, and C). You can configure each port as either input or output. Ports A and B are always used for digital data I/O, while port C can be configured for digital data I/O, control, status, or handshake signals.

     Table 2. NI 650x Connector Overview

     Digital I/O Power-Up State Selection

     You can power up the PCI-6503, PC-DIO-24, PC-DIO-96, and PXI-6508 DIO lines in a user-defined state ?C either high or low. On these devices, each line is connected to a 100 k? resistor, and you can use a jumper to select whether the lines of the device power up in the high or low state. The DAQCard-DIO-24 and PCI-DIO-96 have 100 k? resistors that always pull high.

     SCXI ?C High-Performance Modular Signal Conditioning (See Figure 1)

     SCXI is a modular high-performance signal conditioning system that serves as a front end to your DIO device. The SCXI modules for DIO offer isolation, extended voltage ranges (up to 250 Vrms), increased current switching capabilities, and expanded channel counts (up to 3,072 I/O lines). In addition to SCXI modules for DIO, your SCXI signal conditioning system can include modules for analog output and generalpurpose switching when cabled to a DIO device. With SCXI, you can create integrated, flexible high-channel-count measurement systems with signal conditioning components tailored to your needs. See page 270 for details on SCXI signal
