This section explains the PC setting to use command required in Check Point (Handset)(P.40).

<Preparation>

• Serial JIG cable: PQZZ1CD300E*
• PC which runs in DOS mode
• Batch file CD-ROM for setting: PNZZTG6481RU

*: If you have the JIG cable for TCD500 series
(PQZZ1CD505E), change the following values of resis-
tance. Then you can use it as a JIG cable for both TCD300
and TCD500 series. (It is an upper compatible JIG cable.)

Connect the DC Power or Battery to BATT+ and BATT-.

Connect the JIG cable GND (black) to GND.

Connect the JIG cable UTX (yellow) to UTX and URX (red) to URX.

*: COM port names may vary depending on what your PC calls it.

If repairing or replacing BBIC (FLASH type), EEPROM and X'tal, it is necessary  to download the required data such as Program-
ming data or adjustment data, etc in memory.
The set doesn't operate if it is not executed.

First, operate the PC setting according to The Setting Method of JIG (Base Unit)(P.49).
Then download the appropriate data according to the following procedures.

(*1) XX: country code, YY: revision number, ZZ: Voice Prompt
“XX”, “YY” and “ZZ” vary depending on the country version. You can find them in the batch file, PNZZ- mentioned in The Setting
Method of JIG (Base Unit) (P.49).
(*2) Refer to Check Point (Base Unit) (P.36)

Items

How to download/Required adjustment

BBIC (FLASH type)
(IC7)

Programming data is stored in memory.

1) Make sure to connect the JIG cable, then disconnect the DC
Power in order to download the data.
2) Execute the command “flw480 *********.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
“TG6421XXrevYY.bat”. (*1)
11) Clock adjustment: Refer to Check Point (G). (*2)

EEPROM (IC401)

Adjusted parameter data is stored in memory.
(country version batch file, default batch file,
etc.)

1) Change the address “0000” 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
“TG6421XXrevYY.bat”. (*1)
4) Clock adjustment: Refer to Check Point (F). (*2)

FLASH (IC421)

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 "VPDL2009 -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 down-
load is successfully completed. 

X'tal (X1)

System clock

Clock adjustment data is in EEPROM, adjust the data again
after replacing it.
1) Refer to Check Point (F). (*2)
