You can find them in the batch file, PNZZ- mentioned in TheSetting Method of JIG (P.57).When adjust the frequency the BT Unit.Note:: Enter keyItems How to download/Required adjustmentBBIC(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 downloadthe data.2) Default batch file: Execute the command “default.bat”.3) Country version batch file: Execute the command“TG7871US_US_RevXXX_YYY.bat”. (*1)4) Clock adjustmentFLASH1 (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 DCPower 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 thePC 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“TG7871US_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 againafter replacing it.1) Apply 5.5V between DCP ad DCM with DC power.2) Input Command "sendchar sfr", then you can confirm thecurrent value.3) Check X'tal Frequency.(10.368MHz ± 41Hz).4) If the frequency is not 10.368MHz ±41Hz, adjust thefrequency of CLK executing the command "sendchar sfr xx xx(where xx is the value)" so that the reading of the frequencycounter is 10.368MHz ±5Hz.Item Test command DescriptionInput Echo back1 Power on - - Wait 10seconds and connect JIG2 Test mode sendchar XBT 1sendchar #X tsOK#XXTESTEnter"XBT 1" and then "OK" is backwhen it succeeds to enter test mode.3 Confirm a default value sendchar #X nc #XXnc=0x1A Confirm a default value before adjusting thefrequency.4 Adjust the frequency sendchar #X b3 39 19sendchar nc,,#XXTS ch=2441 pwr=19#XXnc=0x,,Adjust the frequency to "2441MHz ± 10kHz" bychanging the value of,Test Point: ANT_BT, refer to Bottom View(P.84)
