Preface The transceiver is programmed by using a personal com- puter, programming interface (KPG-46) and programming software (KPG-102D). The programming software can be used with an IBM PC or compatible. Figure 1

26、 shows the setup of an IBM PC for programming. 5-2. Connection procedure 1. Connect the transceiver to the personal computer with the interface cable. 2. When the POWER switch on, user mode can be entered immediately. When PC sends command the transceiver enter PC mode, and “PROGRAM” is displayed on

27、 the LCD. When data transmitting from transceiver, the red LED is lights. When data receiving to transceiver, the green LED is lights. Note: The data stored in the personal computer must match model type, when it is written into the EEPROM. 5-3. KPG-46 description (PC programming interface cable: Op

28、tion) The KPG-46 is required to interface the transceiver to the computer. It has a circuit in its D-sub connector (25-pin) case that converts the RS-232C logic level to the TTL level. The KPG-46 connects the MIC connector of the trans- ceiver to the computers RS-232C serial port. 5-4. Programming s

29、oftware KPG-102D description The KPG-102D is the programming software for the trans- ceiver supplied on a CD-ROM. This software runs under MS- Windows 98, ME, Windows 2000 or XP on an IBM-PC or compatible machine. The data can be input to or read from the transceiver and edited on the screen. The pr

30、ogrammed or edited data can be printed out. It is also possible to tune the transceiver. KPG-102D TK-90 IBM-PC IBM计算机 KPG-46 Fig. 1 / ?N RK=? ! RJNK=? ? !#$%& ()*+=EhmdJQSF=? !

Summary The flash memory within the microcomputer of the trans- ceiver can be upgraded when new features are added or ex- isting specifications are modified. 6-2. Connection Use the KPG-46 interface cable to connec

33、t the micro- phone terminal of the transceiver and the COM terminal of the PC. 6-3. Programming 1. Run the PC firmware programming software (Fpro.exe). 2. Set the communication baud rate to 19,200 bps. (Do not use other baud rates, as they cannot be used for commu- nications.) 3. Select the new firm

34、ware file. 4. While press the key, turn the transceiver power on. “PROG 19200” will appear on the transceiver display. 5. Confirm the connection between the transceiver and the PC. 6. Press the “Write” button on the PC screen. “PG” will appear on the transceiver display when data reception be- gins.

35、 7. When data reception has completed, the transceiver will calculate the checksum and indicate the results. 8. To repeat the data writing process on additional transceiv- ers, repeat steps 4 to 7. Notes: The TK-90 hardware can use only a baud rate of 19,200 bps for communications. The transceiver b

36、aud rate cannot be changed. A communication error where occur and programming cannot be performed if the firmware programming soft- ware (Fpro.exe) is set to a baud rate other than 19,200 bps. It takes approximately 2 1/2 minutes to reprogram a single transceiver. 6-4. Function 1. While “PROG 19200”

37、 appears on the display, you can cal- culate the checksum by pressing the key. The results will be indicated on the display. 2. While the checksum results are displayed, press the key again to return the display to “PROG 19200”. 7. Clone Mode Memory channel data can be transferred from one radio to

38、another by connecting them via their MIC connectors. The operation is as follows (the transmit radio is the source and the receive radio is a target). The “password” of description by explanation of 1. to 6. are “Read Authorization Password”. 1. Turn the source transceiver power ON with the key held

39、 down. The transceiver displays “CLONE”. 2. Power on the target transceiver. 3. Connect the cloning cable (part No. E30-3382-05) to the MIC connectors on the source and target.

42、ss the key on the source while the source displays “CLONE”. The data of the source is sent to the target. While the target is receiving the data, “PROGRAM” is dis- played. When cloning of data is completed, the source displays “END”, and the target automatically operates in the User mode. The target

43、 can then be operated by the same memory channel as the source. 5. The other target can be continuously cloned. When the key on the source is pressed while the source displays “END”, the source displays “CLONE”. Carry out the op- eration in step 2 to 4. Note: Cannot be cloned if the password (over w

44、rite password) is programmed to the target. 8. Dealer Mode This mode allows you to write the memory channel data and functions to the equipment. This mode is to be used ONLY by authorized service personnel who are maintaining the users equipment. After programming, reset the FPU to disable “Channel

45、setting” and “Function setting”. Transceiv- ers CANNOT be delivered to the end-user with dealer mode enabled. 8-1. Entering dealer mode 1. Press and hold the key while turning the power on. 2. When dealer mode is enabled, “DEALER MODE” appears on the display. Note: Dealer mode (Channel setting and F

46、unction setting) can- not be set when it has been disabled by the FPU. 8-2.
