Factory power on defaults for the CDI-S100 are to set all volume controls to -
∞,
all microphone channels
to 'Open' and the music source to Line 1. Music level data format is set to ASCII character format. The
system reset command reverts the module to the factory default settings and reasserts all the factory
defaults as the power-on defaults. The unit will then behave as it did when it was fresh from the box.
5.7 Table of Commands
5.8 Response Messages
Response messages are returned by the CDI-S100 to help system programmers in debugging the
system, to provide a means of error checking for the system and to supply feedback to controllers that
need to update their display based on the unit settings. Response messages always return the resulting
parameter value if successfully executed. For system, mute and open commands, this will be a lower
case mirror of the message sent to the module; for level and source commands a lower-case absolute
message type is always returned.
5.9 Example commands
1.
Absolute Music Level
We would like to set the music level on a unit to 0dBu. In order to do this we need to recognise the units
highest output level, for this example 20dBu, so we need to decrease the level by 20dB to achieve the
desired output. This gives us 40 ½-dB steps. Since 00 corresponds to the maximum value, we set the
level value to 40. The command required to do this is:
ASCII:
<MU,LA40/>
Byte:
<MU,LA(/>
The modules response should then be:
ASCII:
<mu,la40/>
Byte:
<mu,la(/>
