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.

may show all of the possible ports, regardless of what is physically
available on your meter.
