What are Connection Parameters?
The Connection Parameters are the communication settings needed to connect between the host computer and the
recorder(s) and meter(s). These settings are an essential part of the E-Mon Energy™ application. This section will
show you how to set up the E-Mon Energy connection parameters and communicate with the actual hardware.
This all begins after you install the data communication device(s) and E-Mon Energy. Setting up these connection
parameters is done on the Connection panel of the Database Group. On the connection panel, there are several Data
Links to choose from, a Direct COM Port connection by way of a RS-485/RS-232 converter, a TCP/IP
(Transmission Control Protocol/Internet Protocol) via an Ethernet connection, or a Modem via a phone-line.
Direct COM Port
The Direct COM Port connection is primarily a single point connection using a RS-232 from the computer
into a multi-point communication network using a RS-485 converter (E-Mon Energy Key). The RS-485
converter allows connection to the recorder(s) and meter(s). The RS-232/RS-485 connection is used for an
On-Site connection. The following illustrates the Direct COM Port connection.
