2.5 A very brief guide to Gyda mode set-up
All of these settings are covered in much more detail in chapter 3.2. These are just the most
important settings to get started:
Arguably the most important setting is where to take the input from. If the module was
purchased with the electrical input only, this would be a good starting point:
What this means is that the electrical input will be chosen whenever a signal is present, and
if a signal is not present, the output will frame freeze for 500 ms before resorting to an internal
fallback generator. Here this generator is set to produce just black video frames.
If the module was purchased with the optical input option, the setup could either be like above,
or with the Optical input instead of the Electrical input, or one input could serve as a backup
for the other, with a final fallback to generator, as illustrated below:
Once the input source has been decided, it must be decided how this reference should be
handled by the card:
The “Soft (master)” setting ensures that the card will not track variations in the input frequency
instantly, but average them out.
The rest of the settings on the configuration page either deal with setup of the frame
synchronizer, or with the multiple choice selection of formats for the module outputs. See ch
3.2 for more detailed description of all the available options.
2.6 How to get back to factory defaults?
To access the function that will reset the module and reload the factory default settings, the
module must briefly be put into manual mode. The entire procedure is described in chapter
3.1.3.
