Hello,
We have an old spectrophotometer which contains an outlet saying "printer/computer", and until now a dot-matrix printer has been attached to it. However, the printer is no longer functional, and I am thinking of interfacing an old PC to the spectrometer.
The printer was attached via serial connection (COM2), by a RS-232 cable of 9-pin "female" and 25-pin "male". I can use the same cable for interfacing, but how can I detect signals? Thing is, when the spectrometer finishes its task, we can push a button like "print graph" and the graph is sent to the printer. Can the same thing be done to a computer, but just taking the necessary values to draw a chart in Microsoft Excel, for example?
Thank you for your interest.
