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.56).
Then download the appropriate data according to the following procedures.
Note:
(*1) XXX_YYY: revision number, ZZZ:Voice prompt, AA: Baud rate(9600/19200/57600/115200)
"XXX_YYY and
"ZZZ" vary depending on the country version. You can find them in the batch file, PNZZ- mentioned in
The
Setting Method of JIG
(P.56).
When adjust the frequency the BT Unit or write the MAC address to the BT Unit.

Items
How to download/Required adjustment
BBIC(IC501)
Programming data is stored in memory.
1) Clock adjustment: Refer to Check Point (H).(*2)
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 “AA” to download
the data.
2) Default batch file: Execute the command “default.bat”.
3) Country version batch file: Execute the command
“TG7621US_US_RevXXX_YYY.bat”. (*1)
4) Clock adjustment
FLASH1 (IC601)
Voice prompt data is stored in memory.
(vary depending on country version)
1) Wait more than 15 seconds after connecting the JIG Cable.
2) Execute the command “VPDL2011 -AA ZZZ.bin” (*1).
(writing time: approx. 1 min (115200 bps).)
FLASH2 (IC502)
Program D/L
1) Make sure to connect the JIG cable and 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
“TG7621US_US_RevXXX_YYY.bat”. (*1)
11) Clock adjustment: Refer to Check Point (H). (*2)
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.(10.368MHz ± 41Hz).
4) If the frequency is not 10.368MHz ±41Hz, 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 10.368MHz ±5Hz.
