I am looking for information about special considerations or limitations of the VXI-DIO-128. Where can I find such information? Hardware: VXI/VME/MXI>>VXI Data Acquisition and Instrument Modules>>VXI-DIO-128
Problem: I am in the beginning of developing an application that will use the VXI-DIO-128 and I would like to get started on the correct path. Where can I find information about the limitations or other special issues of the VXI-DIO-128? Solution: There are a few things to consider when developing applications that will use the VXI-DIO-128. Below are some issues presented in the format of a question and answer: 1) Can the VXI-128 be configured to asynchronously report a change in the state of one of its digital input lines? In other words, can it generate an interrupt/signal to report this condition? No, the VXI-DIO-128 does not have this functionality. 2) Can the VXI-DIO-128 be used to perform digital pattern/waveform generation? No. The DIO-128 does not have any counter timer circuitry. 3) Does VXI-DIO-128 support hardware handshaking? Even though the VXI-DIO-128 has a 82c55 chip on it, it does not support handshaking. 4) Are there any compatibility considerations involving VXI controllers? Due to limitations with the NI-VXI and NI-DAQ software, National Instruments VXI data acquisition (DAQ) modules are not supported with the VXIpc-870B or VXIpc-770. These devices include National Instruments modules such as the VXI-MIO-64E-1, VXI-MIO-64XE-10, VXI-DIO-128, and the VXI-AO-48XDC. 5) Can I use all the VXI DAQ modules with a VME interface? VXI-MIO boards require the CLK10, 10 MHz clock for the onboard oscillator. This is phase-locked with the onboard 20MHz clock and will not work with a VME-MXI-2 controller. Related Links: Attachments:
