The GPIO (General Purpose Input/Output) interfaces allow different console
functions being controlled by external control signals as well as generating
control signals depending on the current status of different console functions.
Assignment of functions and control signals to the GPIO connector pins as
well as the behavior of the I/O signals can be freely configured.
Please note that in I/O sharing applications, a GP input may also control a
function of a neighboring system, and a GP output may be controlled from a
function of a neighboring system without additional wiring; refer to
6.5.22.1.
Systems with the Compact SCore can consist of the internal plus up to five
external frames. Since SW V2.2, one additional frame with GPIO cards only
may be used.
Only 16 internal GPIOs, plus one GPIO card with 16 GPIOs in an optional,
external D21m I/O frame supported.
Remote GPIO is a powerful building brick of the Studer RELINK concept.
In order to make GPIO ready to be used for internal Custom Logic as well as
to allow access to remote systems, GPInputs and GPOutputs have been split
up into GPInputs/GPOutputs (physical control inputs/outputs) and GPInput/
GPOutput functions.
GPInputs and GPOutputs are handled as producers and consumers in the
sense of I/O Sharing. A GPInput function can be compared to a LogicalInput,
where a GPOutput function is the counterpart of a LogicalOutput.
GPInput A GPInput consists of a control input on a D21m GPIO or Ethersound card
and the appropriate input logic.
Physical
Input
FixedLabel is defined by the system and remains 'read only'. It contains a
text specifying the location of the physical input, such as 'Int, Slot 3, In 2'.
Label is initialized by the software as 'GPInput N' by default. It can be
changed by the user.
For further details on the parameters and the 'Level' term, refer to
6.5.29.2.1.
The number of GPInputs is configured in the D21m.xml file. It has to match
the number of available physical GP inputs in the D21m system.
GPInputs are either producers or net sources that also may be accessed from
remote systems.
