Appendix 1: GPIs Explained
Introduction
This appendix describes the functionality of the GPIs that are generally used within 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 are:
•
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-
directional I/O. The Contact_N menu item will be used to assign this specific contact to input or output
pools. The choices are Off, GPI_A, GPI_B, GPI_C, etc. to GPI_N, GPO_A, GPO_B, GPO_C, etc. to GPO_N,
depending on the amount of contacts and pools.
