4.3 Energy Analyser D550
4.3.1 Connections to computer
Example 1 (RS232-RS485 connection):
The PC has an RS232 interface and the Energy Analyser D550 an RS485 interface. An interface converter is
required.
Example 2 (direct Ethernet connection):
The PC and the Energy Analyser D550 have an Ethernet interface. Because there is a direct connection, a
“twisted” patch cable must be used.
Example 3 (Ethernet connection):
The PC and the Energy Analyser D550 have an Ethernet interface. The connection is established in a net-
work via a switch or a hub.
Example 4 (BACnet gateway connection):
The Energy Analyser D550 is used as a BACnet gateway with which to connect RS485 devices (e.g. Energy
Meter D370). The Energy Analyser D550 is the Modbus master (RS485) and the Energy Meter D370 the
Modbus slave, whereby the BACnet shows the Energy Meter D370 as the Energy Analyser D550 virtual de-
vice. A Jasic program queries the measurement values for the connected devices and provides the values to
the BACnet.
Example 5 (Modbus gateway connection):
The Energy Analyser D550 is used as a gateway with which to connect RS485 devices (e.g. Energy Meter
D370). The Energy Analyser D550 is the Modbus master (RS485) and the Energy Meter D370 the Modbus
slave, whereby the baud rate to be set for both devices must concur. A Jasic program queries the measure-
ment values for the connected Energy Meter D370 and makes them available for further processing.

- Ethernet interface (option) with the connection types TCP/IP and Modbus via Ethernet
- RS485 interface with the connection type Modbus RTU (RS485)
Connection types
• TCP/IP connection
• A “twisted” patch cable is required in order to establish adirect connection between a PC and a Energy
Analyser D550 via the Ethernet interface. A normal patch cable is used when establishing a connection in
a network (a hub/switch is present).
