Serial communications
The meter supports serial communications through its onboard RS-485 ports.
RS-485
In an RS-485 network, there is one client device, typically an Ethernet to RS-485 gateway. It
provides the means for RS-485 communications with multiple server devices, such as meters. For
applications that require only one dedicated computer to communicate with the server devices, a
USB to RS-485 converter can be used to connect to the server device.
Up to 32 devices can be connected on a single RS-485 bus.
RS-485 wiring
Connect the devices on the RS-485 bus in a point-to-point configuration, with the (+) and (-)
terminals from one device connected to the corresponding (+) and (-) terminals on the next
device.
