RS-485 Bias
You can use the RS-485 bias setting to fine tune communications.
Turn on the RS-485 bias when the meter is acting as a master over RS-485
communications and turn off the RS-485 bias when the meter is acting as a slave. You
can configure RS-485 biasing through the meter’s display or ION Setup.
Configuring serial communications using the display
You can configure your meter’s basic serial communications settings using the display.
Before configuring serial parameters, make sure you have a unique unit ID for your
meter and know the serial network settings (protocol, baud rate, parity and stop bits).
1. Go to Setup Menu > Communications Setup > COM1 Setup.
2. Configure your meter’s serial settings as required.
