New interface for old paper readers

A Swedish company has developed an interface that allows old paper tape readers based on numerical control machines, to be upgraded instead of been characterised as obsolete.
New interface for old paper readers
The rapid computer and electronics technology expansion has led tools and devices that have been used for certain applications, to become obsolete within a few years. Paper tape readers is one of these cases. A specialised computer is incorporated into various manufacturing machines that executes a program that controls the parameters of the machines' functions. Older machines, which did not have memory capacities, used paper tape readers that fed the numerical controls (NC) to the machine.

Modern CAD/CAM systems do not support the paper reading facility and the old NC machines with paper punch devices cannot be useful any more. However, a Swedish company; Industrial Microelectronic Centre AB, has developed an interface that continues to make these old devices useful. The interface connects the readers through a bi-directional RS 232 communication link to CAD/CAM systems. The interface upgrades old paper tape readers and provides capabilities that were not available previously such as the on-line data transfer.

The benefit of using this interface is that the owners of old paper tapes do not have to spend money in order to be compatible with the new technologies. In addition the users do not have to alter their way of working by adopting new methods.
