Input/output ION modules, ports and labels

You can configure the Digital Output, Digital Input, Analog Input, Analog Output, Pulser and Calibration Pulser ION modules to specify which port handles the outgoing or incoming signals.

To assign a port to one of these modules, modify the Port setup register by picking a port from the enumerated list.

NOTE: If the port you want to use does not appear in the Port setup register list, that port is in use by another module. Edit the Port setup register of the module using that port and set it to Not Used. The port is then available to other modules.
