Appendix 2 GPI’s explained
GPI pools
This card has 5 GPI contacts. Since there are several functions you
can control by using GPI’s (for instance: outmode and
up/down/cross-presets and audio presets) you can add each
individual GPI contact to certain GPI pools. Each pool can then be
assigned to control a specific setting.
binary mode or
priority mode
In the
GPI_1
till
GPI_5
settings you can appoint each GPI
contact to one of the 3 available pools. The way these contacts act
together depends on whether the pool works in binary or in
priority mode.
Example 1
If we would like to control the up converter presets using Pool A
(
Up_CtrlA
set to
GPI-A
) and the outmode setting using Pool B
(
Out-mode-Ctrl
set to
GPI-B
). Both pools working in
priority mode. We could do the following:
 Set
GPI_1
to
GPI Prio A
 Set
GPI_2
to
GPI Prio A
 Set
GPI_3
to
GPI Prio A
 Set
GPI_4
to
GPI Prio A

Set
GPI_5
to
GPI Prio B
Pool A now consists of GPI 1, GPI 2, GPI 3 and GPI 4 in a
priority mode, controlling the Up converter preset. Pool B consists
only of GPI 5 (also in a priority mode), controlling the Output
mode setting.
Pool A now works as follows:
GPI_1
status
GPI_2

GPI_2

GPI_4

Set value
0 0 0 0 Up-conv Preset 1
1 0 0 0 Up-conv Preset 2
0 1 0 0 Up-conv Preset 3
0 0 1 0 Up-conv Preset 4
0 0 0 1 Up-conv Preset 5
0 1 1 0 Up-conv Preset 4
(because highest gets
priority)
1 1 1 1 Up-conv Preset 5
(because highest gets
priority)
Pool B now works as follows:
GPI_5 status Set value
0 A out only
1 B out only
