        CSP-RS232I

        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.

         
        Key Features
        • Recommended for lengthy or outdoor RS-232 cable runs
        • Protects control systems from lightning strikes and electrical disturbances
        • Supports RS-232 from 300 to 115.2k baud [1]
        • Passes RX, TX, RTS, and CTS signals
        • 4.5 Kilovolt RMS galvanic isolation
        1. Supports RS-232 only; does not support RS-422 or RS-485.
