GPI Control
An external customer-supplied GPI device can be connected to the
Control
connector
on the rear of the 5820 module to trigger the GPI inputs by user-defined actions.
Connect the GPI control to the 5820
Control
connector pins as shown below. Each
GPI pushbutton should be wired with closure to ground to trigger a crosspoint. It can
also simultaneously output status to light LEDs that are wired to ground as indicated
in the diagram below.
