Display Board interface Flash/ SDRAM The display board interface is on the 16 way FFC flexi IC203 is a 64Mbit (32 bit x 2Meg) SDRAM. It runs at foil connector at location CON202. Power for the 135MHz display also travels on the connector. There are 4 – wires to interface with the VFD driver chip these are IC205 is a 16Mbit (16 bit x 1Meg) intel type flash IC for seen as. program storage (Player software). o XFPDIN - Data to the display board The flash interfaces to the Vaddis V

HDMI output stage Please note: Due to the plug and play nature of the TMDS (Transistion Minimised Differential Signalling) this HDMI/DVI interface, if presented with a reported no consists of a clock signal (TXC+/TXC-) and 3 data HDMI problem it is worth checking all set-up signals (TX0+/TX0-, TX1+/TX1- and TX2+/TX2-). parameters of both the DVD player and the All signals are differential and use current switching Plasma/Projector in use before performing component techniques therefor

Comms and Final video output stage The signals from the main board travel up to the Comms board on connector CON902. The Video signals simply travel via an A-C coupling net before exiting the player via the RCA-phono SKT902 SKT903 sockets at locations and . The RS232 interface is on 9 way “D” type CON900, with IC900 providing the level translation and static protection between the RS232 levels and the 3.3V CON900 CMOS levels required by the VADDIS V, also supplies a +5V Status
