26、e ID is an identification code allocated to each DXM- 6800 mechanism unit. When written to the mechanism unit, the ID is stored in the Flash memory area, managed by the DSP. During servicing of the unit, if and when the mechanism as- sembly is replaced, the Unique ID of the old unit should be writte

27、n to the new mechanism assembly. At the same time, after moving the Unique ID, the ID seal must also be moved. The descriptions herein concern writing Unique ID, using the functions of the DXM-6800 mechanism. It is possible to easily re-write the Unique ID of the mechanism, using this function. * DX

28、M-6800 : X92-5100-00 2. Unique ID The Unique ID is an identification code allocated to each DXM- 6800 mechanism unit. This ID is consisted of 8-digit hexadeci- mal numbers. Example : 9F346D22, 352899AC, etc. The ID number seal is placed on top of the mechanism cabi- net. The 8-digit numbers and char

29、acters are the Unique ID assigned to the mechanism. The Unique ID can be confirmed in the MENU mode. 3. How to write the Unique ID, using the unit In this section, the procedure for writing the Unique ID with the unit is explained. Since this procedure is realized by put- ting the mechanism into a s

30、pecial mode, the unit must first be reset, immediately before conducting the procedure. At the same time, the display mode of the unit must be set to P- Time, prior to shifting into the write mode. Unless set to P- time, 5 seconds after shifting into the write mode, ID digits and ID numbers will be

31、stopped from displaying. 3.1. How to shift into the Unique ID writing mode using the unit Procedure 1. Set the 63pin of the mechanism microcomputer (TMP91CU27) to High. (Connect X32 : IC1 63pin and Back Up 3.3V with a lead.) Procedure 2. Reset the mechanism microcomputer and boot it up again. (Reset

32、ting the mechanism microcomputer and booting it up again can be achieved by cutting off ACC and Back Up power supply once and then re-starting the unit.) Procedure 3. Insert a CD and use it as a source (i.e. let the unit start reading the Disc.) Procedure 4. This completes the start up on Unique ID

33、Write mode. After shifting into the Unique ID Write mode, the display will be as shown in the figure below. (In the Unique ID Write mode, actually, w is displayed first and, after pressing FF key once in the Write mode, q is dis- played.) Figure1. Initial display of the Unique ID Write mode Where, q

34、 Unique ID The contents of what are indicated by x : xx in the time code is the actual contents of the Unique ID. In sections of minutes : seconds, the Unique ID is indicated in decimal numbers. The table below is the correspondence between the decimal and hexadecimal numbers. Decimal numbers0001020

36、s the target Unique ID of the current procedure for writing the ID. The Unique ID in the seconds section indicates the next Unique ID that is to replace the current Unique ID. The digit numbers of the Unique ID will be displayed in the Track Number section of w. w Unique ID digit number : The digit

37、numbers of the Unique ID are numbered 1, 2, 3,. from the left side of the Unique ID. The contents indicated by T-xx in the track number section are the digit number of the Unique ID displayed currently in q. The first digit is the digit number of the Unique ID, which is currently worked upon and dis

38、played in the minute section of the time code. The second digit is the next digit number of the Unique ID, which is indicated in the seconds section of the time code. The values of the T-xx will be changed as the target of the changed Unique ID is moved in the following manner : T-12 T-23 T-34 T-45

39、. T-78 T-81 . The value in the higher digit (i.e. “1” of T-12, for example) is the current target for change in the Unique ID. After the Unique ID has been changed in all of its digits and as the writing takes place, the progress condition of writing is indicated in the w section. The display conten

40、ts are; T-99 : Unique ID writing in progress. T-11 : Unique ID Writing complete (success) T-22 : Unique ID Writing complete (failure) Procedure 5. Changing Unique ID write contents Using Track Up/Down Key, Unique ID contents is changed (In this unit, CONTROL Key is pushed to the left or right.) Usin

41、g FF/FR Key, Unique ID digit to be worked upon is changed. (In this unit, the CONTROL Key is pushed 1 sec- ond or more to the left or right) Procedure 6. Final write contents is determined and written to the mechanism. Using Pause key, the ID is written. (In this unit, the center section of the CONT

42、ROL Key is to be pressed.) Procedure 7. 63pin of the mechanism microcomputer (TMP91CU27) is set back to Low. (Connection lead is removed.) Procedure 8. Reset the mechanism microcomputer, and start it up. (Resetting the mechanism microcomputer and booting it up again can be achieved by cutting off AC

43、C and Back Up power supply once and then re-starting the unit.) Procedure 9. Insert a Compact Disc (CD) and select CD as the source. This determines the type of media to be played. Then, select from the MENU of the unit “ACD Unique ID.” This is done to confirm on the write content of the Unique ID.

44、When re-doing the procedure, start from Procedure 1 again. 3.2. How to change the Unique ID write content: Explana- tion on the Procedures 5-6. When shifting to the Unique ID Write mode, the display will be as shown in Figure 1. This is the beginning of writing. At this point, as has been indicated

45、above, the digit for 10s in the T- xx is the Unique ID digit which is subject for change and its contents is shown in the minutes section of the time code. Then, actual change procedure is as follows : The table below shows the keys to be used. Track Up key Push theUnique ID contents+1 of CONTROL Ke

Note : When in the Unique ID Write mode, the written Unique ID is not displayed. The terminal of the mechanism microcom- puter must be put back to what it was before (63pin to Low). Then, reset the microcomputer and re-boot it for confirming the newly written Unique ID is correc
