Unless detailed otherwise, the data returned is valid only when the answer code is ‘Status update’ or
‘Command accepted, and complete’. When ‘Command accepted, currently processing’ is returned, the
data returned is the data which is currently being processed.
Status changes
Note that Solo Movie shall transmit messages whenever its status changes. These messages shall be
transmitted by Solo Movie at asynchronous intervals.
State changes as a result of other inputs
It is possible that the state of Solo Movie may be changed as a result of user input via the front panel
buttons or via the IR remote control. Changes resulting from these inputs shall be relayed to the RC
(using the appropriate message type) as they occur.
For example, if the user changed the front panel display brightness using the DISP button on the remote
control, a display message (dened below) would be sent to the RC. A similar action would be taken for
all other state changes.
Unless stated, all RS232 commands have an associated status message.
Example command and response sequence
As an example, the command to set the front-panel display of the Solo Movie to ‘full brightness’ (dened
below) is as follows:
STR Zone CC DL Data ETR
0x21 0x01 0x0A 0x01 0x04 0x0D
Assuming that the command was accepted by the DVD player and is being processed, the DVD player
responds to this command with the following sequence:
STR Zone CC AC DL Data ETR
0x21 0x01 0x0A 0x02 0x01 0x04 0x0D
Note: RS232 control is disabled if the iPod option is enabled.
