Configuring serial communications settings using ION Setup

Use ION Setup to configure the meter’s serial communications settings.

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. Start ION Setup.
  2. Open the Setup Assistant for your device.
  3. Select Communications > Serial Settings.
  4. Select Com1 or Com4 tab, depending on which hardware serial port you are configuring.
  5. Select a setting and then click Edit to configure the setting to match your communications system.
