2IntroductionThis is the read-me file for the documentation of the Mac-based Cabernet rework(version 1.1) software. This documentation should be used in conjunction with the ADICabernet service manual. Refer to the appendix A for descriptions on the availablesoftware features and functions in this rework software.Hardware Requirements1. Power PC with PCI slot and serial ports.2. ADS USB card.3. Quantum 801GF with Mac serial cable connected to serial printer port.4. Minolta CA100 with Mac serial cable connected to serial modem port.5. 28V DC power brick with ADC to VGA/USB adapter board.6. Multi-meter7. Helmholtz cage.8. Hand degausser.9. Insulated alignment tools.Hardware Setup Mac CPUPower Brick 801 GFMinolta CA100RS232RS232USBVGA
3CA100 Equipment Setup1. Check that the CA100 has been set to FL.2. Check that the baud rate has been set to 2400.3. Connect the DB25 connector of the serial cable to the CA100 RS232 terminal and theDIN 8 to the Mac serial modem port.4. The Minolta color analyzer CA100 must be calibrated with a high accuracycolorimeter (e.g. LMT) or photometer for the following color temperature in thememory channels:· Channel 1 = 4100.· Channel 2 = 5000.· Channel 3 = 6500.· Channel 5 = 9300.· Channel 6 = Red.· Channel 7 = Green.· Channel 8 = Blue.Software Requirements1. Mac OS 8.6 or above.2. USB card support drivers version 1.1 drivers or above.3. Apple monitors (version 2.0.3) - Tobiko software.4. Apple Mac Cabernet rework software.Alignment Condition Requirements1. Unit-under-test (UUT) must be in burn-in with full white pattern (generated frompower brick when no external video signal is sensed) for a minimum of 30 minutes.2. UUT must be properly degaussed before any alignment.3. Alignment must be done in the helmholtz cage.
4Alignment ProceduresTurning ON the unit1. Click on “Preset & read” to ensure that the Cabernet can be found on the USB.Message should show “UUT found”, if not check the connection. Also ensure that thecheck box “Preset Contrast” is ticked.2. Click on the button “UUT ON” to power ON the UUT. Important note: Must clickon the button “UUT OFF” to power OFF the UUT after adjustment. Failure to click“UUT OFF” will result in higher power consumption in sleep mode and abnormalpower ON operation (i.e. degauss activated before powering ON the Mac) whenconnected to a Mac CPU.Data Upload1. Equipment: Mac with USB.2. Condition:(a) UUT must be able to communicate through the USB.3. Select [Rework>Factory Data>Upload All] to upload the EEPROM contents from abad video board.4. The EEPROM contents from the bad video will be stored in a factory data file format.The EEPROM data in this file can be transferred to the new video board by using thedownload function described next.5. If the contents from the bad video board cannot be uploaded, then the alternative is touse the factory backup files available at Apple’s ftp site for Cabernet. The address forthe ftp site will be made known later. Use the unit serial number to search for theunit’s factory backup file.Data Download1. Equipment: Mac with USB.2. Condition:(a) UUT must be able to communicate through the USB.3. Select [Rework>Factory Data>Download All] to download the EEPROM contentsfrom a video or a factory backup file to the new video board. Use this function toreduce the amount of adjustment needed after a change of the video board .bysearching it using the UUT serial number.4. Power OFF and ON the DC power supply to the UUT for the download EEPROMdata to take effect.5. Check through all the adjustments against the specifications to ensure that thedownloaded EEPROM data work with the new video board.6. Re-adjust when necessary.B+ voltage check and adjustment1. Equipment and adjustment procedure is the same as detailed in the service manual.2. Condition:(a) Timing mode is 1024x768@99Hz – select [Quantum Data>801 Formats>Cab 3 =1024x768@99Hz](b) Pattern is White – select [Quantum Data>801 Patterns>White Page].
