Data Processing Certain adjustment items require the microprocessor data to be read out or the displayed data (hexadecimal numbers) on jigs or adjusting remote commander to be calculated to get adjustment data. In such a case, convert hexadecimal numbers into decimal numbers once, then make calculation, and convert its result into hexadecimal number as adjustment data.
  • Page 22 6. Power ON Procedure for Adjustment (1) Connect an extension cable to the adjusting remote commander. (2) After making sure that the HOLD switch on the adjusting remote commander is not turned on (not at left (NOR) position), supply 9.0 Vdc to the DC IN (J301).
  • Page 23 [Preset Data Writing] Connection: (1) Connect the adjusting remote commander to the CN902 on YM-11P board. Data Writing Procedure (1) Set data: 01 to page: 1, address: 00. (2) Enter the data given in the table below. Note: To write the data to the EEPROM, press the PAUSE button on the adjusting remote commander each time the data is set. (3) After writing all data, set data: 00 to page: 1, address: 00.
