Hi;

I am trying to understand this section from ifi_aliases.h (~ line 50)

"""
Ports 1 & 3 have their inputs duplicated in ports 4 & 2 respectively. The
inputs from ports 1 & 3 may be disabled via the 'Disable' dip switch
located on the Operator Interface. See Users Manual for details.
"""

I looked for further reference in the manual, but I am not sure which
document I should be looking in.

Anyone have a better reference, or can say something more
about what "have their inputs duplicated" means?

What is it used for?
