Serial communications

The meter supports serial communications through its onboard RS-485 ports. Your meter supports the 4-wire RS-485 option module through use of the existing Com1 port.

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.
