Introduction The Unique ID is an identification code allocated to each DXM- 6800 mechanism unit. When written

36、 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 written to the new mechanism assembly. At the same time, after moving the Unique ID, the ID s

37、eal 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. * DXM-6800 : X92-5100-00 2. Unique ID The Unique ID is an identification code allocated to

38、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 characters are the Unique ID assigned to the mechanism. The Unique ID can be confirmed in t

39、he 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 special mode, the unit must first be reset, immediately before conducting the procedure.

40、 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 stopped from displaying. (Please refer to the instruction manual as for the setting met

41、hod for P-Time.) 3-1. How to shift into the Unique ID writing mode using the unit Procedure 1. Set the 63pin of the mechanism microcomputer (91CU27UG5UR8) 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. (Resetting

42、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 Write

43、 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.) Figure1Initial display of the Unique ID Write mode Where, q Unique

44、 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.

46、inutes section is 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 num

47、ber : The digit 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 wor

48、ked upon and displayed 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 tar- get of the changed Unique ID is moved in the following man- ner :

49、T-12 T-23 T-34 T-45 . 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 contents are; T-99 : Unique ID writing in progress. T-11 : Unique ID Writing complete (success) T-22 : Unique ID Writing complete (failure) Procedure 5.
