DESCRIPTION OF BLOCK DIAGRAM
1. Video Controller Part.
This part amplifies the level of video signal for the digital conversion and converts from the analog video signal to
the digital video signal using a pixel clock.
The pixel clock for each mode is generated by the PLL.
The range of the pixel clock is from 25MHz to 149MHz.
This part consists of the Scalar, ADC converter, TMDS receiver.
The Scalar gets the video signal converted analog to digital, interpolates input to 1920 x 1080 resolution signal and
outputs 8-bit R, G, B signal to transmitter.
2. Power Part.
This part consists of the one 3.3V regulators to convert power which is provided 12V in Adapter board, 12V is
provided for convert circuit.
3. MICOM Part.
This part is including video controller part. And this part consists of Reset IC and the Micom.
The Micom distinguishes polarity and frequencies of the H/V sync are supplied from signal cable.
The controlled data of each mode is stored in scalar.

1. Parallel port setting
Enter your bios, and do as followings.
a) Integrated peripheral
b) Super IO Device
c) Parallel port mode
you should set the” parallel port mode” to SPP for using the DOS EDID tool surely.
2. EDID Write
1. Connect the signal line of monitor with DDC recorder.
2. Choose the DDC RECORD program, and it shows on the screen, then choose the correct source base on the
monitor.
3. Click “LoadFile”, then key in the manufacturer name, model name, product code, then choose the correct
model name base on the monitor.(as Fig.2)
4. Scan serial No. to DDC recorder by Bar Reader, then read again in the Verify SN.
5. According to the message of DDC program, when the picture as fig.1 appears, it will show DDC record has
finished.

Please check Manufacturer Name, Vendor Assigned Code, Monitor Name, Serial Number：*****[????????*****]
(it must be the same as Bar Code),Week of Manufacture：**,Year of Manufacture：****,Checksum：** (It must be
the same as the last byte of data table, as follows picture shows). Above of all must be right, then if it shows the
green “PASS”, it means record succeeds ,the red “Fail” means record fails; Then check the power supply and
signal line, and ensure they are connected well ,then do DDC record again from the third step.
