In MDS, processing way for RS-232C is different b

19、etween during remote ON and during remote OFF. To carry out the request from RS-232C, send off the remote ON command at first to set the MDS itself to remote ON mode. When MDS is not in remote ON mode, it does not reply to a command from RS-232C. 5-2Condition of MDS during remote ON MDS with remote

20、ON is capable of accepting any command via RS-232C. When MDS enters remote ON mode, MDS stops all workings and forcibly enters “STOP, REPEAT OFF and CONTINUE mode”. While MDS is remote ON, it accepts controls from RS-232C only and does not accept followings: Keys of main unit Wireless remote control

21、 Wired remote control Parallel remote input Relay playback/recording input (Do not operate keys of main unit during remote ON to avoid malfunctions.) While MDS is remote ON, INPUT switch and REC mode switch (E52 only) can be changed in main unit only. These switches cannot be changed by remote contr

22、ol. While MDS is remote ON, output for the following operation can be done according to an alternation of inside condition: Parallel remote Relay playback/recording input By sending off remote OFF command, MDS enters remote OFF mode. 5-3Condition of MDS during remote OFF When the power is turned on,

23、 MDS is in this mode. While MDS is remote OFF, it accepts followings: Keys of main unit Wireless remote control Wired remote control Parallel remote input Relay playback/recording input 9 As for the command from RS-232C, only remote ON command is acceptable. When MDS receives a command other than re

24、mote ON, it sends back a message means impossible execution. 5-4Summary To control MDS with RS-232C, it is necessary to send remote ON command after turn- ing on the power to enter remote ON mode. MDS does not accept an input other than the one from RS-232C during remote mode. 10 6Transmission data

25、6.1Structure of this section In this section, details about each command are mentioned. The commands are classified as function, data length, data, details of function and example of transmission packet. Function:General functions of commands are shown. Data length:Data length of commands are shown.

26、 Data:A fixed data is shown in hexadecimal notation. As for a variable value, meaning and range of the value are explained. Details of function:Explanation of the function of commands, notation for command use and etc. are mentioned. Example of transmission packet: Concrete examples of transmission

27、packet are shown. 6.2REMOTE MODE Function:To set the remote mode Data length:2 bytes Data:10H, Status Status:03H = On 04H = Off Details of function:This command changes remote mode of MDS. As MDS does not accept controls from RS-232C when remote mode is not ON, it is necessary to use this command to

28、 enter remote ON mode. When remote mode is OFF, if a packet other than the remote mode on is sent from PC, MDS sends back “CANT EXECUTE”. When MDS receives this command, it forcibly enters stop mode, REPEAT OFF or CONTINUE. In this condition, MDS accepts controls from RS-232C until it enters remote

29、mode OFF. 11 In remote ON mode, MDS does not accept keys of main unit, wire- less/wired remote control, parallel input or Relay Play/Rec. On the other hand, parallel output and relay output are carried out. Change of INPUT switch is acceptable even when remote mode is ON. Refer also to section 5 abo

30、ut details of remote mode. Example of transmission packet: Set remote mode to ON. 7EH, 07H, 05H, 47H, 10H, 03H, FFH 6.3POWER Function:To set the power mode Data length:2 bytes Data:01H, Status Status:02H = On 03H = Off Details of function:As well as the POWER button on the remote control, this comma

31、nd switches STANDBY mode and POWER ON mode. When “POWER Off” command is send during toc reading, MDS is turned off after toc reading is completed. However, “Power” comes back immediately from MDS. When the power mode of MDS is actually changed, MDS sends off “STATUS DATA” automatically. “STATUS DATA

32、” is reliable value to grasp the power condition accurately. Example of transmission packet: Set the power to ON. 7EH, 07H, 05H, 47H, 01H, 02H, FFH 6.4PLAY Function:To start playback. Data length:2 bytes Data:02H, 01H 12 Details of function:This command starts playback. When this command is sent in

33、stop mode, MDS starts playback from top of a disc. When this command is sent in playback pause mode, MDS starts playback again from the point. When this command is sent in recording pause mode, MDS starts recording. Example of transmission packet: Start playback. 7EH, 07H, 05H, 47H, 02H, 01H, FFH 6.

34、5STOP Function:To stop playback Data length:2 bytes Data:02H, 02H Details of function:This command stops playback. When this command is sent in playback mode, MDS stops playback. When playback is started again after the above, MDS starts playback from top of a disc. To start playback again from the

35、previous stopping point, “PAUSE ON/OFF” command must be used instead of this “STOP” command. Example of transmission packet: Stop playback. 7EH, 07H, 05H, 47H, 02H, 02H, FFH 6.6PAUSE ON/OFF Function:To pause playback/to cancel pause Data length:2 bytes Data:02H, 03H Details of function:This command

36、has the same function as the PAUSE key in the main unit or the remote control. 13 In short, this command changes playback mode to playback pause mode, and playback pause mode to playback mode. It changes recording pause mode to recording mode, and recording mode to recording pause mode. When this co

37、mmand is sent in stop mode, MDS enters playback pause mode at the top of a disc. Example of transmission packet: Start playback again in playback pause mode. 7EH, 07H, 05H, 47H, 02H, 03H, FFH 6.7PAUSE ON Function:To pause Data length:2 bytes Data:02H, 06H Details of function:This command changes pla

38、yback and recording mode to pause mode. Different from “PAUSE ON/OFF” command, this command does not cancel pause mode. So, if this command is sent during playback pause mode, playback does not start. The similar condition is applied to recording. Example of transmission packet: Pause playback durin

39、g playback mode. 7EH, 07H, 05H, 47H, 02H, 06H, FFH 6.8FF/REW OFF Function:To cancel FF/REW Data length:1 byte Data:00H Details of function:This command stops FF or REW operations during each operations due to FF or REW command. 14 As FF or REW is the command to start operation of FF or REW, the oper

40、ation will carried out to the end of a disc if only these commands are given. “Stop operation during FF or REW”, that is similar condition to the one of when FF or REW key in the main unit is released. Example of transmission packet: Stop FF during FF operation. 7EH, 06H, 05H, 47H, 00H, FFH 6.9REW F

41、unction:To start rewinding Data length:2 bytes Data:02H, 13H Details of function:This command has the same function when REW key in the main unit is pressed. To stop REW, send “FF/REW OFF” command. When this command is sent in playback pause mode, playback start- ing point goes back until “FF/REW OF

42、F” command is given or starting point reaches to the top of the disc. No sound is heard during this period. When this command is sent in playback mode, as well as in playback pause mode, playback starting point goes back until “FF/REW OFF” command is given or starting point reaches to the top of the

43、 disc. Sound is heard in this case. Example of transmission packet: Start REW operation. 7EH, 07H, 05H, 47H, 02H, 13H, FFH 6.10FF Function:To start fast forward Data length:2 bytes Data:02H, 14H 15 Details of function:This command has the same function when FF key in the main unit is pressed. To sto

44、p FF, send “FF/REW OFF” command. When this command is sent in playback pause mode, playback start- ing point goes forward until “FF/REW OFF” command is given or starting point reaches to the end of the disc. No sound is heard during this period. When this command is sent in playback mode, as well as

45、 in playback pause mode, playback starting point goes forward until “FF/REW OFF” command is given or starting point reaches to the end of the disc. Sound is heard in this case. Example of transmission packet: Start FF operation. 7EH, 07H, 05H, 47H, 02H, 14H, FFH 6.11PREV TRACK Function:To skip back

46、to a previous track Data length:2 bytes Data:02H, 15H Details of function:This command has the same function when AMS- key in the main unit is pressed. When this command is sent in the top of a track in playback pause mode, playback starting point goes back to the top of the previous track, and play

47、back pause mode is remained. When this command is sent in the middle of a track in playback pause mode, starting point goes back to the top of the current track, and playback pause mode is remained. When this command is sent during playback, playback starts from the top of the current track. Example

48、 of transmission packet: Start playback from the top of the current track. 7EH, 07H, 05H, 47H, 02H, 15H, FFH 16 6.12NEXT TRACK Function:To skip forward to the next track Data length:2 bytes Data:02H, 16H Details of function:This command has the same function when AMS+ key in the main unit is pressed

49、. When this command is sent during playback, playback starts from the next track. When this command is sent in playback pause mode, starting point goes forward to the top of the next track, and playback pause mode is remained. Example of transmission packet: Start playback from the top of the next track. 7EH, 07H, 05H, 47H, 02H, 16H, FFH 6.13REC Function:To prepare for recording Data length:2 bytes Data:02H, 21H Details of function:This command has the same function when REC button in the main unit is pressed.
