We have a cnc grinder with a control made by Andron. The connection between the control and the operating panel is via a hybrid fiber optic cable. The connectors attach via a 9 pin serial port and convert the electric signal to an optical signal and back again to an electric signal. Cable we have is defective and we can't seem to find anyone that has even heard of this kind of set up. I have pictures of the originals if anyone thinks they can help.
I have an old one I took off a machine but unfortunately I cannot find the fire optic.
But the company is still in operation and the one I have is Black Box Corporation.
They should be able to fit you up.
