Recently I bought a communication cable (1761-CBL-PM02) for MicroLogix controllers but there is Caution Tag on the cable package saying "An optical isolator is recommended between the controller and your programming device". I would like to know what this optical isolator is and whether I should use it. Any advice on this would be much appreciated.
