The TCC-82 is a signal isolator that provides bi-directional serial communication with full electrical isolation between two RS-232 devices. It isolates both sides of the connection optically to provide protection from lightning surges, accidental high voltage shorts and removes the problems associated with ground loops.

In addition to the Tx and Rx data lines, the TCC-82 also protects the RTS/CTS handshake lines. If you are suffering spurious data errors on your serial connection, the TCF-82 may well be the solution to your problem.
