Serial communications
The meter supports serial communication through the RS-485 port.
In an RS-485 network, there is one master device, typically an Ethernet to RS-485
gateway. It provides the means for RS-485 communications with multiple slave
devices (for example, meters). For applications that require only one dedicated
computer to communicate with the slave devices, a USB to RS-485 converter can be
used to connect to the master device.
Up to 32 devices can be connected on a single RS-485 bus.
RS-485 configuration
Before connecting your device to the RS-485 bus, use the meter’s display, webpages
or ION Setup to configure your meter’s default RS-485 settings.
Your meter has one RS-485 connection.
Your meter must have a unique unit identifier (address) and have the following settings
match the rest of the devices on the RS-485 bus:
• Protocol
• Baud rate
• Parity and stop bits
You can configure the following settings to help optimize communications
performance:
• RTS delay
• RS-485 bias
You can use a communications converter (USB to RS-485 or RS-232 to RS-485) or an
Ethernet gateway device to connect to your meter.
Serial protocols and ports
Your meter supports serial communications protocols on its RS-485 port.
