Amodule exchange procedure

23、 will be set up for this purpose. The module can be removed from the product by removing 4screws and the transformer and loosing the connectors.This module is the complete CD recorder, it contains the following parts:CD Mechanism (CDM4009). Underneath this mechanism a PCB is mounted which is adjuste

24、d to the mechanism (lasercurrent settings are stored in EEPROM).Loader Assy. This mechanical assy takes care for the tray control.Main PCB. This PCB takes care that the (analog or digital) signal to be recorded is converted into a suitable signal whichcan be recorded on the disc.Digital signals with

25、 an other sampling frequency then 44.1kHz will be converted in the sample rate converter (DASP) to44.1kHz.Analog signals will be first converted into a digital converter by the AD converter.This PCB also takes care that the signal from the CD (playback) is converted into a suitable digital signal (o

26、r analog viathe DA converter).The main microprocessor controls the several functions of this PCB. 1.2.2 Power Supply PCB.This PCB contains the Power SW, which is jointed the Power bottom on the front panel. This PCB consists of power supply part. The power suppluy part delivers the several voltages

27、for the diffrent PCB in the DR2100. On this power supply one fuse (primary side) is mounted on this PCB. All parts are available as spare parts. 1.2.3 Terminal PCB.This PCB coutaius input and output terminals. All parts are available as spare parts.1.2.4 Display Board.This PCB contains the Display,

28、which informs the user about the status of the recording/playback process and it also takescare for scanning the keys on the front panel. The information from the keys is fed via a I C connection to the mainmicroprocessor on the CDR loader module. Information which needs to be displayed is also fed

29、via this I C line from themain microprocessor on the CDR loader module to the display controller.The parts for this PCB are available as service parts so this PCB can be repairable up to component level.22IMPORTANTIn case of replace the CD-R module MAR775, the initialization is necessary.Please init

30、ialize the CD-R module with following orders.1. Press the POWER button (POWER ON) while depressing FINALIZE button and RECTYPE button together.2. LCD Display shows;WAIT PGM PROTOCOL PGM PORT END3.
