General assembly parts list CD62 (text) Circuit Description Summary Remote Control/PIC Micro The main Motherboard/Display PCBs for the Diva CD players Remote control data is received from the IREye on the display may be assembled as three different versions: PCB and buffered by TR300 and TR301. The Programmable Interrupt Controller converts the RC-5 format data into the NEC ! DiVA CD62 (text) - With alternate components fitted format required by the Sony micro. and the 92DAC upgrade connections omitted (L933AY). ! DiVA CD72 (text) - With the standard set of Motor Driver components fitted (L899AY). ! DiVA CD92 (text) - With analogue components and The status of the drawer is indicated to the micro by two micro connectors omitted, for use as a host motherboard for switches `INSW' and `OUTSW' on SK205. The micro controls the plug-in 92DAC (L934AY). the drawer motor via driver IC303. All systems are based on a Sony kit, comprising CDM14BL- 5BD25 CD transport / loader / laser mechanism, micro-controller Clock Buffering and fluorescent display. The clock and data signals LRCK, ADATA and BCLK from the mechanism connector SK300 are double buffered by IC300 Power Supplies before being delivered to the DAC. The CD62 may be fitted with any of the following transformers dependant on supply voltage required:- Power-On/Reset ! 230VAC only - part number L849TX ! 115VAC only - part number L850TX The power-on reset signal XRST (or RESET) is generated by ! 100VAC only - part number L851TX R409, C410 and IC404. When the power is turned on, C410 is initially uncharged and pin 11 of IC404 is at high voltage, and Later models are fitted with L867TX which is a 230/115VAC thus the output is low. After a short time, C410 is charged via transformer. R409; IC404 pin 11 is then low, and the output switches high (RESET is de
