4.8.1.2. General Purpose Inputs
As shown in Figure 4-8, the 7700PTX-MVP has 20 general-purpose inputs. Each input has an internal
pull-up resistor.
To enable GPI signal monitoring the protocol associated with the GPIs must be set to GPI. If set to
None, GPI monitoring will not occur. The Virtual Offset field represents the offset added to the physical
GPI pin number when determining the Virtual GPI (VGPI) pin number. The states of the VGPI pin
numbers are transmitted to the MVP.
7700PTX-MVP is required – each with a unique Virtual Offset.
