Command Descriptions
INFORMATION REQUEST
Command: 00FH
Function : Requests the information such as model
name and version of the MDS-B5.
Data: None
RETURN command: 08FH
STOP, PAUSE, CUE, STANDBY,
EJECT
Command: 010H
Function : Activates the STOP, PAUSE, CUE,
STANDBY or EJECT function.
• STOP function
Stops the motor and rotation of the disc. The
mechanism becomes completely stationary.
• PAUSE function
The MDS-B5 stores the audio signals in the
buffer memory while in the PAUSE mode,
therefore the audio signals are immediately
played without the time lag when the deck
changes to PLAY mode. Also, while pausing at
the beginning of a track, the silent portion at the
beginning of the track is skipped if the AUTO
CUE function is turned on. This enables the
playback starting exactly from the rising point of
the sound. Note that the AUTO PAUSE
function is automatically turned on when the
AUTO PAUSE function is turned on. For
details, see “AUTO PAUSE, AUTO CUE
SELECT” Command: 030H.
• CUE STANDBY function
When this command is output, the deck locates
the position where the playback started the last
time and pauses at the point. This function is
useful for relocating a certain point in a track
after confirming the point by listening.
• EJECT function
The deck ejects the disc. This command is
active only when the deck is stopped. There is
no command for inserting the disc since the disc
insertion is possible only through manual
operation. Therefore, you cannot insert the disc
once ejected by command operation using an
external remote controller.
