System compatibility

AT-DIO-32F belongs to NI AT series DAQ board.It works on PC AT compatible ISA systems,supports NI-DAQ driver,widely used in production test,lab measurement and industrial process monitoring.It is spare part for legacy test equipment overhaul.

Function

AT-DIO-32F is a high-speed 32-bit parallel digital I/O interface for ISA bus.It supports DMA,interrupt and programmed I/O data transmission,realizes digital signal input,output and pattern generation.RTSI bus enables trigger synchronization with other AT series DAQ boards.

Installation

Insert AT-DIO-32F into ISA slot of AT compatible computer chassis,secure the bracket.Connect 50-pin I/O cable and RTSI cable.Take ESD protection before power-on.

Interface

‑50-pin I/O connector

‑RTSI trigger bus connector

‑ISA edge connector

‑+5V DC power supply

Feature

AT-DIO-32F classic legacy NI DAQ board.Typical faults:gold finger oxidation,TTL circuit damage,connector pin corrosion.Clean gold finger and test channel before replacement.

Diagnostic

Fault phenomenon:no I/O response,channel read/write failure,RTSI sync error.Check ISA address configuration,clean gold finger,test digital channels and handshake circuit.

Product Brief

AT-DIO-32F is NI ISA high-speed 32-bit parallel digital I/O board with TTL level,450kwords/s transfer rate and RTSI synchronization.Mainly used for maintenance and replacement of old industrial test and measurement equipment.ESD protection must be followed during handling.
