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 (defined 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’ (defined
below) is as follows:
