This prevents electrical surges from interfering with data integrity or damaging the attached RS-232 or RS-422 equipment. The RS-232/RS-422 Optical Isolator receives power from the attached interfaces. The RS-232 port receives power from the RS-232 interface. The RS-422 port receives power from the RS-422 interface. Transmitting data between buildings? You'd better guard against damaging ground loops. Ground loops occur when you link devices powered by separately grounded AC power sources. But a BLACK BOX(R) Opto-Isolator stops them by internally transforming electrical signals into fiber optic light pulses. This "air gap" breaks the copper connection between the two AC systems, preventing potential equipment damage while enabling data to flow uninterrupted. I have 4 unused RS232-422's. Place a Bid!
