NI PCI‑7813R Reconfigurable Digital RIO Board Product Description

Overview

NI PCI‑7813R is a digital reconfigurable I/O board of the NI R‑Series RIO family, built on standard PCI bus for industrial PC installation. This NI reconfigurable digital board carries a user‑programmable Virtex‑II XC2V3000 FPGA and 160 bidirectional digital I/O lines, programmed via LabVIEW FPGA. PCI‑7813R executes hardware‑timed high‑speed digital control, signal generation and custom protocol processing independent of the CPU. It is a mature legacy NI board, widely used for HIL simulation, test bench renovation and spare‑part replacement of existing R‑Series digital RIO systems.

Features

NI PCI‑7813R reconfigurable digital RIO board supports individual configuration of each DIO channel as input, output, counter, timer, PWM or encoder interface. This NI RIO board uses FPGA hardware logic to run deterministic timing tasks without operating system latency. PCI‑7813R is equipped with three 68‑pin VHDCI connectors for field wiring expansion. The NI reconfigurable board supports custom digital communication interfaces, pattern generation and high‑speed bit‑stream capture. It works with LabVIEW FPGA, NI‑RIO driver and compatible SCB‑68 terminal blocks and SHC68‑68‑RDIO shielded cables.

Principle

NI PCI‑7813R reconfigurable digital RIO board receives FPGA bitfile from the host PC during initialization. The FPGA implements user‑defined hardware logic to sample input digital signals, generate output patterns, count pulses and decode encoder signals. All timing and decision logic runs directly on FPGA hardware for low jitter and deterministic response. Host PC exchanges setpoints, recipe data and measurement results with the FPGA via PCI bus. The digital channels connect to external sensors, actuators and communication transceivers through VHDCI cables and terminal blocks.

Applications

NI PCI‑7813R reconfigurable digital RIO board is widely deployed in hardware‑in‑the‑loop simulation, automotive test benches, aerospace component verification, custom communication protocol test, encoder simulation and high‑speed digital pattern generation. This NI RIO board is used for production test systems, semiconductor inspection equipment and industrial control loop simulation. PCI‑7813R fits legacy test system maintenance and spare replacement for existing R‑Series digital RIO setups.

Installation & Maintenance Notes

Follow official NI R‑Series hardware manuals during installation of NI PCI‑7813R reconfigurable digital RIO board. Use anti‑static protection before handling the board. Install the matching NI‑RIO driver and LabVIEW FPGA runtime, and verify the bitfile compatibility after replacement. Inspect VHDCI connectors and cable shielding regularly, especially in high‑EMI test environments. Back up the FPGA bitfile and host project before board replacement. Confirm exact part number PCI‑7813R before spare‑part swap‑out to verify FPGA resource and channel count matching.
