RS-232 Isolator: CSP-RS232I
Introduction
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. 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.
