The two sides of the isolator are
powered from a 12VDC power
supply and maintain isolation. This
powering configuration allows the
device to be run in any system with
only a single supply, regardless of the
power levels on the RS-232 ports.

In order to maintain the required
isolation, use the recommended
power supply. Using an unregulated
power supply may negate the
isolation.
