4    CX462 Configuration

To install the CDI-S100 in the CX462, the CX462 needs to be correctly configured.  To allow the module
to have full control of the unit there is a set of internal jumpers which need to be checked and set.  In all
configurations the module will have control over the master microphone level.

4.1 Microphone Access controls

To allow the CDI-S100 to mute individual microphone channels, internal jumpers J1-4 in the CX462 need
to be present and connecting the header pins.  If one of these jumpers is disconnected it will mute the
correspondingly numbered channel until the access pin is pulled to 0V.

4.2 Music source select and volume

In order for the CDI-S100 to control the music source select and volume controls, internal jumpers J7-10
in the CX462 need to be in the 'SW' position.  This allows control of the signals to be switched by the
'ANALOGUE/DIGITAL' switch on the rear panel (SW1).

Jumpers J7 and 8 switch the music controls between front panel and switchable control, ‘FR’ and ‘SW’
positions respectively.  Jumpers J9 and 10 switch the music controls between forced analogue and
switchable controls, ‘AN’ and ‘SW’ positions respectively.  The controls must be switchable to allow the
CDI-S100 to control them, as any other setting will effectively disable CDI-S100 control over that
particular function.

Location of Jumpers J1- 4 and J7- 10

5    Cloud SP v1: Communications protocol

Messages are sent to the CDI-S100 using the Cloud SP1 protocol.  The protocol is designed to be human
readable where possible, to enable easy debugging and to allow system testing by typing commands into
a terminal emulator program such as HyperTerminal.

5.1 Message Structure

All messages 

to

the CDI-S100 use upper case letters, all messages 

from

the CDI-S100 are in lower case.

Commands are enclosed within a header character (“<”) and a terminator sequence ("/>"). The CDI-S100
will reset its message decoding software upon reception of a header character, discarding any previously
un-decoded partial messages. The CDI-S100 will decode a message upon reception of the terminator
sequence. If the decoded message is valid it is executed and a response message returned.  The
message has two fields separated by a comma, the destination field and the command field.
