Appendix 3
GPI’s explained
Introduction
This appendix describes the functionality of the GPI’s generally used
within the Synapse based products.
General
functionality
The physical contacts of a General Purpose Interface can be assigned by
the user. In our cards the General Purpose Interface contacts (GPI
contacts) will be named as General Purpose Input (GPI) or General
Purpose Output (GPO). The GPI inputs and outputs are assignable to
different preset banks. These preset banks (GPI pools) can be used to
switch multiple settings at once.
Some examples of these functions:
▪
Input selection
▪
Output mode
▪
Up conversion aspect ratio for channel A and B
▪
Down conversion aspect ratio for channel A and B
▪
Cross conversion aspect ratio for channel A and B
▪
Transparent aspect ratio (equal in-output) for channel A and B
▪
Insertion of VI, WSS, AFD (S2016) for channel A and B
▪
Audio shuffling, gain and phase
Contact
assignment
The physical contacts can be assigned as input or output. In the menu of
a card, these will be called
Contact_N
depending on the amount of
contacts available. Contacts could be Inputs, outputs or bi-derictional
I/O. The
Contact_N
menu item will be used to assign this specific
contact to input or output pools. The choices are
