Product Introduction

HiTechnic NXT IRLink Sensor for LEGO Mindstorms NXT

Introduction

The NXT IRLink Sensor allows communication between the NXT and other LEGO models that utilize

infrared communications.

The new LEGO R/C trains

and sets using Power Functions motors and controllers such as the Technic

Bulldozer and the Monster Dino can all be easily controlled with the NXT using an IRLink.

Programming

Mindstorms NXT-G

The IRLink Sensor can be programmed using LEGO Mindstorms NXT-G Software by importing one of the

available IRLink Sensor Block. There are three blocks available for the IRLink,

• PF IRLink Block - Controls Power Functions motors with IR Control unit

• Train IRLink Block - Controls LEGO R/C trains

• RCX IRLink Block - Transmits commands to a Mindstorms RCX and receives RCX sensor

readings

These and other HiTechnic sensor programming blocks are available from the downloads

page.

PF IRLink Block

The Power Functions IRLink Block allows you to select the channel (1 - 4) to match the channel selected

on the Power Functions Controller.

Each motor may be controlled independently by setting the command to Stop, Forward or Reverse.
