I am new with the concept of hardware interface.
My requrement is, suppose one weighing machine is there. We have multiple LT terminals that are connected to PC. Each has own IP adress. Each terminal sends the weighing data string(containing net weight and gross weight).

Means I have to pull that net weight and gross weight reading data in to my software.

So for that what are the thing to be require for that harware interface. And is some coding required plz send me.

Plz explain me step by step.

Thanks and Regards
Harish
