ADJUSTING THE PC INTERFACE (CPCi-0036CE01/03. PC I/F Unit)
1. Initializing the EEPROM
1) Press the S5001 switch to call the process mode. 2) Pick up the item S1 on the SSS menu. (The S1 is used to initialize the PC interface alone. Do not select the item S2 because otherwise the other data than the PC interface will be initialized.)
2. Adjusting the levels
1 Oscilloscope setting Set the range to DC 1 V/div. and 5 µ s/div. 2 Input signal Feed the XGA 1024x768, 60Hz gradation waveform signal and the DTV (720P for example) signal. 3 Level adjustment and checking 1) Press the S5001 switch to call the process mode. 2) Adjust R750 so that the voltage at test point TL119 be 2.6 ±0.05V. 3) Set the BRIGHT data on the A/D menu to 125. 4) Adjust the R-BRIGHT data on the A/D menu so that the voltage at TP3 be 1.7V. 5) Adjust the G-BRIGHT data on the A/D menu so that the voltage at TP2 be 1.7V. 6) Adjust the B-BRIGHT data on the A/D menu so that the voltage at TP1 be 1.7V. 7) Make sure that the GAIN data on the A/D menu is 155. 8) Connect the synchroscope to TP3. Adjust the R-D data on the A/D menu so that the signal�s white peak be 3.6V. (Be also sure that the white and black portions of the gradation are not corrupted.) 9) Connect the synchroscope to TP1. Adjust the B-D data on the A/D menu so that the signal�s white peak be 3.6V. (Be also sure that the white and black portions of the gradation are not corrupted.) 10) Connect the synchroscope to TP2. Adjust the G-D data on the A/D menu so that the signal�s white peak be 3.6V. (Be also sure that the white and black portions of the gradation are not corrupted.) 11) Feed the DTV signal instead. Enter only the Y component, not the Pb and Pr components. 12) Adjust the R-BRIGHT data on the DTV menu so that the voltage at TP3 be 2.65V. 13) Adjust the B-BRIGHT data on the DTV menu so that the voltage at TP1 be 2.65V. 14) Press the S5001 switch to exit the process mode.
