When written to the me

40、chanism 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 seal must a

41、lso 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 each DXM- 6

42、800 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 the MENU mod

43、e. 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. At the same

44、 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. 3.1. How to shift into the Unique ID writing mode using the unit Procedure

45、 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. (Resetting the mechanism microcomputer and booting it up again can be achieved by cutting off ACC and Bac

46、k 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 mode. After shifting into the Unique ID Write mode, the display will be as shown in the figur

47、e 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.)
