GPI SETUP
Gpi Encoding
gpi enc:none
gpi enc:standard
gpi enc:hex
gpi enc:afv hex
The GPIs can be configured to operate in one of 3 Encoded modes. In
these modes, many of the GPI inputs are pre-assigned to a function. The
unused inputs are still available for the user to assign to a particular function
using the Program Gpi’s menu item.
When the GPI Encoding is set to none, all 14 inputs are available for the
user to assign to particular functions using the Program GPI menu item for
the particular GPI. Section 3.12.5 describes how to program individual GPI
functions.
Sections 3.12.3.1 to 3.12.3.3 describe how each of the GPI encoding modes
works and which inputs are available for user assignment.
3.12.3.1. Standard GPI Encoding
Standard GPI encoding is designed to allow simple select an ‘Audio follow Video’ switch of one of the
input groups to one of the output busses. There are twelve GPIs to select each input and two GPIs to
perform the switch either the AFV1 or AFV2 output busses.

3.12.3.2. HEX GPI Encoding
HEX GPI encoding is designed to audio follow video or breakaway switch selection. Four inputs are
encoded to select one of the 12 inputs. Eight GPI inputs perform the switch to one of the video or audio
busses or one of the AFV groups. There are two GPI inputs available for user defined functions.
