Annette, i am still working on the hardware side at the moment but i will be interfacing my IR TX n RX through the parallel port of the computer. i think i will then, when i get onto it, let labview look for a change in signal in the data ports of the parellel port. this should be enough to allow LabView to start and stop a timer. im not exactly sure how this is done yet as i am new to labview but when i find out i will be posting so VI's for people to assist me if they can. thanks Hatim

Bob, thanks for the reply, i am actually working on a major project at the University of london and i was encouraged to use labView by my project supervisor. i was going to use java but he said that it may be good to learn to use Labview. however i am a complete beginner! so, i would be greatful if you could help with any code etc as although this is just a part of my project i wont be including it in the final report. my main aim is timing competitive swimmers and creating a pacing system. however in the meantime i need to prove the concept on land. thanks for your previous post , i'll read up on the things you mentioned. kind regards Hatz

hi there all , i need to perform a simple test for the first part of my project. i need to be able to pass my hand through a Transmitter/reciever of some sort and Labview has to recognise that i have interupted the beam. can anyone help me with regards to of any code that can register this on LABview. ideally i would like to have a TIMER start..then STOP when an IR or Laser beam is Interrupted. any help or advice is appreciated regards Hatz London
