Optical Isolation & Surge Protection

Optical isolation and surge protection are supported by the USB-COM-SI-M.

The RS-232 port is optically isolated with 2000 volt DC optical isolation. The optical isolation protects your PC or notebook from spikes and surges on the RS-232 network by converting the elctrical pulse into an optical signal and then changing it back to an electical pulse. Your computer is well protected, since the surges and spikes cannot cross the optical link.

The RS-232 port is protected by a surge protector to withstand electrostatic discharges and power surges up to 25KV ESD. Surge suppression on all signals prevents damage caused by lightning or high voltages.
