I. Basic Information

Model: PCI-DIO-32HS

Original Model: NI PCI-6533

Bus: Standard 32-bit PCI bus, not compatible with PCI-E slots

Channels: 32 bidirectional high-speed digital I/O

Level Standard: 5V TTL/CMOS level

Product Status: Fully discontinued, only in stock as second-hand

Companion Driver: Traditional NI-DAQ driver, does not support DAQmx

II. Core Performance Parameters

Transmission Rate

Mode I/O: Maximum 2 MHz, Handshake I/O: Maximum 1 MHz

Port Division

Divided into 4 independent 8-bit ports, which can be freely combined for 8-bit/16-bit/32-bit usage. Electrical parameters

Single-channel output drive current 24mA, input compatible with standard TTL signals

Synchronization function

Built-in RTSI real-time synchronous bus, supporting precise synchronization triggering of multiple boards

Communication mode

Supports various hardware handshake timing sequences, suitable for instrument parallel data interaction

Interface form

68-pin SCSI-II high-density interface, providing all digital channels and control signals

Insulation characteristics

No electrical isolation, only applicable to indoor low-voltage clean industrial environments

III. Main features

High-speed parallel digital input/output, suitable for batch digital signal acquisition and output

Power-on IO state can be software-configured

Equipped with DMA high-speed transmission, significantly reducing CPU usage of the computer

Perfectly compatible with old measurement and control equipment, automated test benches, logic timing control systems

Supports continuous occurrence of digital patterns, external trigger acquisition

IV. Compatible systems and software

Supported systems: Windows 2000, XP, Windows 7 32-bit

Not supported: Win10, Win11 and mainstream 64-bit systems of the latest version

Development software: Old versions of LabVIEW, CVI, VC++ and other traditional industrial control development programs

V. Hardware installation steps

Turn off the host power supply and disconnect the power, then open the case

Insert the board card into an idle standard PCI slot and fix it

Connect an 68-pin connection cable to interface with external TTL digital devices

Power on and install the NI-DAQ classic version driver, restart to complete identification

Confirm that the digital board card is properly loaded in the device manager to use it

VI. Application scenarios

Digital signal control for old automated production lines

Parallel high-speed data transmission of instruments

Logic timing control test, batch output acquisition of pulse signals

Replacement and repair of the original same model equipment

VII. Precautions

Do not connect high-voltage signals, to avoid burning out the board card channels

In industrial strong interference sites, it is recommended to add an optical isolation module

Only old PCI motherboards are available, new full PCI-E motherboards cannot be installed

The new version system cannot be perfectly compatible, new projects should directly select the upgraded version

VIII. Alternative models

Upgrade general model: PCI-6534 / PCIe-6534

Isolated industrial model: PCI-6527
