DENON CD PROTOCOL DRIVER

Introduction:

The Denon CD driver is selectable from the Configuration dialogs in the
MP4000 software under the ICM4020 and SEM4020.  The driver provides
translation for a selected subset of the MPCL cue statements into the
message set for the Denon player.  The driver was written for and tested
on the Denon DN-961FA and DN-951FA CD players.

MPCL Cue Statements

Note: 'DenonCD' is an alias for a rack/slot/port for which the Denon CD
driver has been selected:

STOP 'DenonCD' ;

	transmits 'W', causes player to stop

SEEK 'DenonCD' TRACK t ;

	transmits 'QT', where T is a BCD packing of the specified track t;
      the player ques up at track t.

SEEK 'DenonCD' TO f ;

	transmits 'TMSF', where M, S, and F are BCD packings of the
      specified minutes, seconds, and frames.  Note that the frames
      value is calculated base on the assumption that f in the statement
      has been entered as 00:mm:ss.ff, where ff is the desired frame at
      a 30 f/s rate (i.e., ff is 0 to 29).  In the absence of a preceding
      SET FRAME command (see next paragraph), then, the frame number from
      the cue statement is multiplied by 2.5 to achieve the 75 f/s
      operation used by the Denon player.  Thus, the actual frame numbers
      transmitted to the player will be 0,2,5,7,10,12,15,17,20,22,25,27,
      30,32,35,37,40,42,45,47,50,52,55,57,60,62,65,67,70, and 72.

SET 'DenonCD' FRAME f ;

      In the event that the user requires specification of frames not
      reachable by this 'multiply by 2.5' operation, described above, a
      SET FRAME command can be used to recover the full precision of the
      player.  The SET FRAME command should immediately precede the SEEK
      TO command in the cue, with a frame number f from 0 to 74.  With
      this 'notification', the SEEK TO command described above will use
      this value for the frames value transmitted to the Denon player.

PLAY 'DenonCD' ;

      transmits 'P' to player, causes the player to play from the currently
      cued position.

SEND 'DenonCD' "anystring" ;

      transmits 'anystring' to player.  This command permits the user to
      send arbitrary messages to the player, to cover any aspects of
      control not supported directly in the driver.
