V. Loading of Programs into the Device
Place YDNB.CFG file with the program into the root directory of a MicroSD card with a FAT or FAT32 file
system. Insert the MicroSD card into the Device. After a few seconds, you should observe three LED flashes:
1. Three red flashes
indicates that the card cannot be read.
2. A green followed by two red flashes
indicates that the YDNB.CFG file cannot be found
on the memory card and the current Device configuration was saved to the YDNBSAVE.CFG file.
3. A red followed by a green and another red flash indicates that the YDNB.CFG file contains
errors and was not accepted by the Device. The text file YDNBERR.TXT was created in the root
directory of the memory card, comprising an error log.
4. Three green flashes indicates that the file has successfully been loaded into the Device. The text
file YDNBSAVE.CFG was created in the root directory of the card, comprising the current program
and used settings.
The Device performs compilation of the program text into bytecode. Before the Device saves a program
in the YDNBSAVE.CFG file, it decompiles the bytecode to text. This is why the contents of the YDNB.CFG
and YDNBSAVE.CFG files can differ from each other.
The YDNB.CFG file must contain at least one interpretable line of code (a setting, filter etc.) without errors,
in order to be loaded into the Device.
To modify the current program, insert a memory card into the Device that does not contain a YDNB.CFG
file. The LED of the Device will flash green, red, red. This inidcates that a YDNBSAVE.CFG file, comprising
the current program, was saved onto the card. This program can be modified, saved as YDNB.CFG, and
loaded back into the Device.
