Overview

Product overview

Key product information and technical features.

The PC-OPDIO-16 belongs to NI's legacy Plug and Play ISA/PC/AT hardware group. Its digital interface is organized into two fixed-direction, optically isolated 8-bit ports.

Software integration requires attention to the original driver environment. NI identifies this model among devices requiring NI-DAQ 6.9.x or earlier, rather than NI-DAQmx or Traditional NI-DAQ 7.x.

Separate 8-bit digital input and output ports.
Optical isolation on the digital ports.
Programmed I/O transfers without a digital I/O clock.
Digital port operations without hardware handshaking.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Are the digital ports bidirectional?

No. Port 0 is an 8-bit output port, and port 1 is an 8-bit input port.

Can the PC-OPDIO-16 use NI-DAQmx?

No. NI lists it as unsupported by NI-DAQmx 7.x and later and Traditional NI-DAQ 7.x. NI specifies NI-DAQ 6.9.x or earlier for programming this device.

Does the board support digital handshaking?

No. NI's LabVIEW reference identifies the PC-OPDIO-16 as a device without handshaking support and recommends digital port VIs for such devices.
