3.1 Connection of the Inputs

The 8 inputs are used to trigger the playback of folders. An input is activated if it is connected to the ground
of the player. The states of all the inputs are combined to form a binary code identifying the folder to play.
Triggering devices can be connected to these inputs in one of two ways:
Up to 8 triggering devices directly connected to the player inputs. In that case, the associated folders
•
are 001, 002, 004, 008, 016, 032, 064, and 128.
Up to 255 triggering devices connected to the player inputs through a circuit encoding their ID. In
•
that case, the associated folders are 001 to 255. Such an encoding circuit can be made out of
diodes. An optional extension board interfacing up to 15 triggering devices to the player inputs is
available.
