12.8. Things to Do after Replacing IC or X'tal

If repairing or replacing EEPROM or 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.
12.8.1. How to download the data
12.8.1.1. Base Unit
First, operate the PC setting according to The Setting Method of JIG (P.51).
Then download the appropriate data according to the following procedures.
FLASH (IC502)
EEPROM (IC611)
FLASH(IC601)
X'tal (X501)
Note:
(*1) XXX_YYY: revision number, ZZ: Voice Prompt
"XXX_YYY" and "ZZ" vary depending on the country version. You can find them in the batch file, PNZZ- mentioned in The
Setting Method of JIG (P.51).
Items
Programming data is stored in memory.
Adjusted parameter data is stored in memory.
(country version batch file, default batch file,
etc.)
Voice prompt data is stored in memory.
(vary depending on country version)
System clock
How to download/Required adjustment
1) Make sure to connect the JIG cable, then disconnect the DC
Power in order to download the data.
2) Execute the command "flw441 *********.hex".
3) Connect the DC Power.
4) Press the PC Enter key once.
5) After a few minutes, "Successful upgrade" is displayed on the
PC indicating downloading has finished.
6) Detach the JIG cable, then disconnect the DC Power.
7) Connect the DC Power.
8) Connect the JIG cable again, and execute the command
"getchk", then confirm the checksum value is correct. If the
downloading fails, start again from step 1).
9) Default batch file: Execute the command "default.bat".
10) Country version batch file: Execute the command
"TG3721_BX_RevXXX_YYY.bat". (*1)
11) Bandgap voltage & frequency adjustment: Refer to
Adjustment of Base Unit (P.55).
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
"TG3721_BX_RevXXX_YYY.bat".
4) Bandgap voltage & frequency adjustment: Refer to
Adjustment of Base Unit (P.55).
1) Wait more than 15 seconds after connecting the JIG Cable.
2) Execute the command "VPDL2011 -57600 ZZ.bin" (*1).
3) Wait until "VP file transfer complete." is displayed on the
P.C. (writing time: aprox. About 1 min)
4) Detach the JIG cable to disconnect DC Power. Then
reconnect the DC Power and confirm whether the download is
successfully completed.
Clock adjustment data is in EEPROM, adjust the data again
after replacing it.
1) Frequency adjustment: Refer to Adjustment of Base Unit
(P.55).
