CNI2 Operating and Installation Guide

"Special Purpose" Output

The CNI2 will use a "special purpose" output to control some operation within the unit assembly,
such as turning a power supply on or off. At this time the "Special Purpose" output only applies
to Line-12, which is the J7 connector. If a unit is shipped with a line programmed as a Special
Purpose output, it should not be changed unless you understand the implications.

Configuration of a "Special Purpose" Output

As a "Special Purpose Output" the signal on the J7 connector will go active shortly before the
cellular radio is powered up to make a call. It will return to the inactive state shortly after the
cellular radio is powered down. The active state (3.3V or to 0V) is defined by the "Active High"
or "Active Low" selections on this screen.
