Command format and answer format
The host shall be designed to send block
The DN-C635 uses commands each of which consists of a data row (some commands no need PC) composed of command codes (CC) and parameter codes (PC).
check characters (BCC) following ETX, with the data row enclosed in STX (text start: 0x02) and ETX (text termination: 0x03). The DN-C635 shall complete command receive with correct BCC codes.
Here are the formats. Commands <STX> <CC> <PC0> <PC1> <PC2> <.> <PCn> <ETX> <BCCH><BCCL>
STX (Start of TeXt) CC (Command Code) PC (Parameter Code) ETX (End of TeXt) BCC (Block Check Character) 0x02 Command code Numbers of parameters are defined for each command. 0x03 CC + PC0 + PC1 + PC2 + + PCn + ETX = XY (hex) Each of X and Y is 4 bit long, X, Y=0,1,2,3,4,5,6,7,8,9,A, B, C, D, E, F BCCH is an ASCII code converted from X (higher 4 bits of sum) and BCCL is converted from Y (lower 4 bit of sum). BCCH and BCCL are ASCII coded data.
Answers<STX> <RC> <AC> <PC0> <PC1> <PC2> <> <PCn> <ETX><BCCH><BCCL>
STX (Start of TeXt) RC (Reply Code) AC (Answer Code) PC (Parameter Code) ETX (End of TeXt) BCC (Block Check Character) 0x02 Reply code (=Command code) Answer code Numbers of parameters are defined for each command. 0x03 RC+AC + PC0 + PC1 + PC2 + + PCn + ETX = XY (hex) Each of X and Y is 4 bit long, X, Y=0,1,2,3,4,5,6,7,8,9,A, B, C, D, E, F BCCH is an ASCII code converted from X (higher 4 bits of sum) and BCCL is converted from Y (lower 4 bit of sum). BCCH and BCCL are ASCII coded data.

For BCC; 1) Add from command through STX. 2) Take two lowest digits in BCC sum. (tens & ones place) 3) Convert tens & ones place numbers in to hex. Examples: BCC=337 BCC=107 BCC= 45 BCC= AC BCCH=33, BCCL=37 (discard hundredths place 3) BCCH=30, BCCL=37 (discard hundredths place 1) BCCH=34, BCCL=35 (convert directly) BCCH=41, BCCL=43 (convert directly)

2.1 Protocol for data transmission and reception
This devices serial protocol is based on half-duplex communication. Therefore the host shall transmit commands and receive answers according to the following procedure.
Basic procedure 1) The host selects a prefer command and transmit codes to device. The host shall not send each byte within 40sec because the device cannot receive within 40sec after previous byte. 2) The host shall wait devices answer before transmit next command. Reading RC, AC and PC bytes, the host can get acknowledge whether the device received previous command correctly or not. 3) When transmit the command which causes some functions, the host shall get devices status that the device becomes ready. The Read Status command is used for this purpose. 4) The host shall complete the transmission of one command within 40 msec. 5) The device shall return answer within 5 seconds. 6) The device cannot receive any command within 2 second after power turned on.
Communication errors 1) In case of communication error such as overrun, framing, or parity error occurred, the device returns NAK (15h) code within 80msec from the start of command transmission. When received NAK (0x15) code, the host shall transmit previous command again immediately. 2) If the host detects communication error while receiving the answer, the host shall send NAK (0x15) code within 80msec from beginning of receipt. The device sends same answer again after received NAK code within 80msec. 3) The host shall send previous command when there is no answer from device.

Professional CD Player

DN-C635

DESCRIPTION

The Denon DN-C635 is a professional CD player housed in a single 2RU rack-mount chassis. It is the successor to the popular DN-C630 and includes many new feature enhancements for professional applications such as CD-RW playback, shock memory and CD text support. Auto Cue to music and instant start insures there are no blank spots at the beginning of the track to be played. A new D-Sub 9 pin port can be configured for either RS-232C or RS-422A communication. An Infra-red sensor has been added behind the front panel for wireless control. Designed for use in a wide range of applications the DN-C635 will satisfy the needs of demanding installations. Radio station, pre-production, post production, studio and theater are just some of the examples where the DN-C635's features will provide solid performance when quality sound is required. For background music applications, the DN-C635 supports MP3 decoding for hours of music playback. Functions on this CD player include a variable pitch of 12% (approximately 2 octaves) and a Single/Continuous Playback mode. The 1x/10x wrap-around track select knob allows for quick track access. A digital SPDIF port is located on the back panel for connecting to digital systems along with sync and cascade connectors for use with multiple DN-C635 units or the DN-780R tape recorder. Digital servo adjustment has been automated so that the optimum setting is always obtained for the type of CD being played, compensating for any changes occurring in the pickup over years of use.

( range is 0 to 60 sec., 7 steps.) Power-On Playback 1) Play the entire disc from the first track of the disc. 2) Play the program sequence from the beginning. Next-Track Reserve Turning the track select knob during playback reserves thenext track to be played back. After the current track has finished playing back, the unit continues by playing back the reserved track. Parallel (D-sub 25-pin) (GPI Control) Allows DN-C635 users to use play, pause and other simple functions easily by contact closure control. Fader Start via D-Sub 25 pin connector Start Only - Player starts when fader switch is turned on. Start, Pause - Player starts when fader switch is turned on. - Player pauses when fader switch is turned off. Sleep function for extended transport life 3 Function Preset groups for multiple users. Cascade Function (CASCADE IN/OUT) ports of multiple DN-C635 units can be linked to enable continuous relay playback among the units. Synchronized Recording The port (EXT. SYNC OUT) of DN-C635 unit can be linked to other Denon recorders (DN-780R etc.) to enable simultaneous recording. (MAX 20 Units) Display of Playback Location by bar graph Elapsed or Remaining Time Mono Playback (L & R channels mixed) Next Track Standby Pressing the STDBY/CUE button during play stops play back and makes the unit enter a standby at the beginning of the next track for quick track review.
