12.6. Things to Do after Replacing IC or X'tal
If repairing or replacing EEPROM and X'tal, it is necessary to download the required data such as Programming data or adjustment
data, etc. in memory.
The set doesn't operate if it is not executed.
12.6.1. How to download the data
12.6.1.1. Base Unit
First, operate the PC setting according to
The Setting Method of JIG
(P.46).
Then download the appropriate data according to the following procedures.
Note:
(*1) WW: country code, XXX_YYY: revision number
"WW" and "XXX_YYY" vary depending on the country version. You can find them in the batch file, PNZZ- mentioned in
The
Setting Method of JIG
(P.46).
Items
How to download/Required adjustment
EEPROM (IC611)
Adjusted parameter data is stored in memory.
(country version batch file, default batch file,
etc.)
1) Change the address “0001” of EEPROM to “55” to download
the data.
2) Default batch file: Execute the command “default.bat”.
3) Country version batch file: Execute the command
“TG4111US_WW_RevXXX_YYY.bat”. (*1)
4) Clock adjustment
X'tal (X1)
System clock
Clock adjustment data is in EEPROM, adjust the data again
after replacing it.
1) Apply 5.5V between DCP ad DCM with DC power.
2) Input Command "sendchar sfr", then you can confirm the
current value.
3) Check X'tal Frequency.(13.824 MHz ± 100 Hz).
4) If the frequency is not 13.824 MHz ± 100 Hz, adjust the
frequency of CLK executing the command "sendchar sfr xx xx
(where xx is the value)" so that the reading of the frequency
counter is 13.824000 MHz ± 15 Hz.
