SUMMARY

The Main/Display PCB for the new FMJ CD23.it will only the Accept 9 CD Ring Dac
Module(L816) FMJ Changes Will Not Power up existing 8SE Dac Modules.

This Board is Based on the ALPHA 7SE CD Board used without DAC Circuitry

This Board Is designed to accept a second transformer which supplys the analogue
Supply instaed of the frame (as in the standard 9CD Version)

The system is based on a Sony kit, comprising CDM14-5BD10 laser mechanism &
loader, micro-controller and fluorescent display.

CIRCUIT DESCRIPTION

Power Supplies & Reset/Mute

Selection of 230V or 115V mains operation is made by inserting a fuse into the
appropriate position and placing in the correct mains frame transformer . The
mains transformer has three secondary windings:

1. Provides a unregulated +19 and -19V supplies for the 9 DAC discrete
regulators

2. This produces the digital, motor drive and fluorescent display grid
supplies:

+7.3V (Z206) Mechanism and motor driver supply
+5V (Z208) General digital logic supply
+5V (DAC) (Z207) Supply to DAC
+5V (CLK) (Z203) Supply to system clock generator
-30V (Z209) Display grid voltage.

3. Provides an AC supply for the display filament.

The power-on reset signal XRST is generated by R17 and C29. When the power
switch is turned off one of its poles discharges C29 quickly. This, along with the
AMUTE signal from the micro, controls the output mute transistors via level
shifter Q3.

Remote Control/PIC Micro

The remote control receiver is mounted on a separate PCB, joined to the main
PCB by a 4-way ribbon cable. The PIC micro controller converts the RC-5 format
data into the NEC format required by the Sony micro. The PIC also controls the
configuration of the digital filter/DAC on the DAC board.

Micro controller & Display Board

The system micro controller Z212 has the following functions:

! Control of the mechanism & decoder on the CDM14
! Control of mute, attenuation and de-emphasise for the DAC
! Direct drive of the fluorescent display
! Remote control decoding
! Keyboard scanning

The keyboard scanning works by connecting the keys to a resistor ladder on an
ADC input to the micro. Pressing a key presents a unique voltage to this input.

The remote control data contains a `
Customer Code' that identifies this as an
Arcam product. The diode network D291 to D297 configures the micro to accept
this code.

Motor Driver

The status of the drawer is indicated to the micro by two micro switches `
INSW'
and `OUTSW'on SK205. The micro controls the drawer motor via driver Z210.

Digital Output

SPDIF format digital output signal is generated by the decoder on the mechanism
assembly. This is passed through isolating transformer T202 to a single phono
socket SK5.

Optical digital output via Z2 is also tapped off the digital output signal. Power is
supplied to Z2 via Z3 a 78L05 regulator.

TEST METHOD

The test procedure for the FMJ CD23 is essentially the same as for the Alpha 9
CD with reductions in the digital and analogue supply voltages

Test in the same way as is usual for Alpha 8/8se/9CD but with Following Changes.
