IO421

IO421 — The IO421 is an LVDT/RVDT and Synchro/Resolver converter I/O module

Introduction

The IO421 and IO422 are multi-functional I/O modules supported by Speedgoat for the use with Simulink Real-Time.

The IO421 I/O module is a PCI device and has three independent plug-in slots. Each slot can be populated with a function-specific I/O sub-module listed in the table below.

The IO422 I/O module is a cPCI device and has three independent plug-in slots. Slot 1 and slot 2 can be populated with any function-specific I/O sub-module listed in the table below. Slot 3 can only be populated with a Reference/Excitation sub-module (IO422-5).

This manual provides I/O pin mapping information for LVDT/RVDT simulation (NAII 5* plug-in), and instructions on how to use the provided Speedgoat Simulink Real-Time drivers.

Note that screenshots of the driver block dialogs are for IO421 but are the same for IO422.
