Specifying an I/O port in a module

For detailed information and instructions on configuring Analog and Digital I/O modules, see the ION Reference.

Configure the Digital Output, Digital Input, Analog Output, Pulser, and Calibration Pulser modules to specify which port handles the outgoing or incoming signals. To assign a port to one of these modules, simply modify the Port setup register by picking a port from the enumerated list. This can be done with both ION Setup and the Designer component of Power Monitoring Expert.

The following table describes the ports that can be configured (in the Digital Output, Digital Input, Analog Output, and Calibration Pulser modules) to handle outgoing or incoming signals.

NOTE: You must confirm the meter I/O options (onboard and/or I/O Expander) to determine which of the following apply to your meter.
