factory-installed communications options are also available. These
options make is possible for a user to select Powermonitor 3000 units

communications option supports bi-directional data transfer with
external devices or applications. Metering measurement, logging,
configuration and status data may be accessed via communications.
Communications options are set in the Master Module. You may
