The two computer interface ports on the Interface Expander 
are called Basic ports because they supply simple UPS sig-
naling for On Battery and Low Battery conditions in the 
UPS. For further information see “Simple versus smart sig-
naling: Table 3,” on page 7.

The Interface Expander Configuration DIP switches control 
the shutdown operation of the unit. See “Configuring the 
Interface Expander” on page 19.
