Crestron® RS-232 Isolator

Provides protection of a Crestron RS-232 COM port against lightning surges and other electrical disturbances.

The CSP-RS232I is an accessory designed to protect a Crestron® control system's COM ports from lightning surges and other electrical disturbances brought through the RS-232 control line [1]. By electrically isolating any distant, outdoor device such as a pool & spa controller or irrigation system, the CSP-RS232I can prevent damage to the control system in the event of a near lightning strike, ground-loop, or short from a high voltage line.
