For my final year mechanical project, I will be using my college's tensile test machine. The machine has a digital load meter that displays the load that the machine applies onto the specimen.
At the the back of the load meter is RS 232 port. I was planning on connecting an Arduino to this port through a MAX232 in order to read the load values and save them to a SD card.The machine is a TecQuipment SM100-E102.
How would I go about getting the data from the load meter, will it be continuously outputting the data, or will it have to be requested.There is a system from the manufacturer of the machine that allows the data to be viewed on a PC, but it is very expensive .
Any help would be appreciated as I am only a hobbyist and have no experience in serial communication.
