thanks alot for all the help! it's working now.... ending with <CR> worked on hyperterminal, but in labview I needed to add the Cariage_Return to the end of the strings I was writing........ rookie error! now i'm just wondering how to arrange my program. it has to basicaly start the machine running, then take readings of the force etc, then stop the machine. I'm thinking sequence structures are the way to go? cheers again, pete

cheers, but i'm on version 7 or 7.1. any chance you could send it in one of those versions? the help is much apreciated!!

QUOTE(ASTDan @ Sep 10 2007, 02:56 PM) thanks alot, in the instructions it says the command has to be ended with <CR>. so for example, for it to read off the current position of the tester, and the force on the load cell, type RB<CR>. is the basic serial VI putting some more characters on the end? or do I need to add something to the end?cheers, pete oh, and the instrument doesn't do handshaking cheers!

Hi all, i'm realy sorry for only asking, and never answering questions. I'm still learning! and yes, I have looked through the archives I'm trying to control and take data from a hounsfield testing machine through serial. I'm using the basic serial write and read VI. I'm able to control the machine through hyperterminal, but when using labview, sending the same strings results in nothing. i've done loopback tests with the labview VI which prove the port works, and labview is comunicating with it. I've even sent strings through labview through a serial wire to another computer with hyperterminal open with no problem. anyone have any ideas why I can't do it through labview at the moment? any help is greatly apreciated!!

Hi, I'm new to labview/testing/labwork, and would be grateful if anyone could give me some clues on how to do my task. I'm making a VI that is used when using a hounsfield tension testing machine. the Vi needs a few Analog input channels including one to measure the force, and one to measure the distance moved etc. I was just wondering if it would be possible to connect the testing machine to a comuter to comunicate through the serial line, i.e control the motor in the machine, and take data collected by the machines computer (the data is usualy sent straight to a printer). appologies if this doesn't make much sense! cheers, pete
