Connection Procedure1. Connect the transceiver to the personal computer withthe interface cable.2. When the POWER switch on, user mode can be enteredimmediately. When PC sends command the radio enterPC mode, and “PROGRAM” is displayed on the LCD.When data transmitting from transceiver, the red LED islights.When data receiving to transceiver, the green LED islights.Note: The data stored in the personal computer must matchmodel type, when it is written into the flash memory.5-3. KPG-22 Description(PC programming interface cable: Option)The KPG-22 is required to interface the transceiver to thecomputer. It has a circuit in its D-subconnector (25-pin) casethat converts the RS-232C logic level to the TTL level.The KPG-22 connects the SP/MIC connector of the trans-ceiver to the computers RS-232C serial port.5-4. Programming Software KPG-101D DescriptionThe KPG-101D 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 orcompatible machine.The data can be input to or read from the transceiver andedited on the screen. The programmed or edited data can beprinted out. It is also possible to tune the transceiver.6. Firmware Programming Mode6-1. PrefaceFlash memory is mounted on the transceiver. This allowsthe transceiver to be upgraded when new features are re-leased in the future. (For details on how to obtain the firm-ware, contact Customer Service.)6-2. Connection ProcedureConnect the transceiver to the personal computer (IBMPC or compatible) with the interface cable (KPG-22). (Con-nection is the same as in the PC Mode.)6-3. Programming1. Start up the firmware programming software (Fpro.exe).2. Set the communications speed (normally, 115200 bps)and communications port in the configuration item.3. Set the firmware to be updated by File name item.4. Turn the transceiver power ON with the Side2 key helddown. Then, the orange LED on the transceiver lights and“PROG 1152” is displayed.5. Check the connection between the transceiver and thepersonal computer, and make sure that the transceiver isin the Program mode.6. Press write button in the window. When the transceiverstarts to receive data, the “LOADING” is displayed.7. If writing ends successfully, the checksum is calculatedand a result is displayed.8. If you want to continue programming other transceivers,repeat steps 4 to 7.Notes: This mode cannot be entered if the Firmware Program-ming mode is set to Disable in the Programming software. When programming the firmware, it is recommend tocopy the data from the floppy disk to your hard disk beforeupdate the radio firmware.Directly copying from the floppy disk to the radio may notwork because the access speed is too slow.6-4. Function1. If you press the Side2 key while “PROG 1152” is dis-played, the display changes to “PROG 192” to indicatethat the write speed is low speed (19200 bps). If youpress the Side2 key again while “PROG 192” is dis-played, the display changes to “PROG 384”. If you pressthe Side2 key again while “PROG 384” is displayed, thedisplay changes to “PROG 576”. If you press the Side2key again while “PROG 576” is displayed, the display re-turns to “PROG 1152”.2. If you press the Side1 key while “PROG 1152” is dis-played, the checksum is calculated, and a result is dis-played. If you press the Side1 key again while thechecksum is displayed, “PROG 1152” is redisplayed.Note:Normally, write in the high-speed mode.7. Clone ModeProgramming data can be transferred from one radio toanother by connecting them via their SP/MIC connectors.The operation is as follows (the transmit radio is the masterand the receive radio is a slave).The following data cannot be cloned. Tuning data Embedded message with password Serial numberThe “password” of description by explanation of 1. to 7.are “Read Authorization Password”.1. Turn the master transceiver power ON with the B keyheld down. If the Data password is set to the transceiver,the transceiver displays “CLN LOCK”. If the password isnot set, the transceiver displays “CLONE”.2. When you enter the correct password, and “CLONE” isdisplayed, the transceiver can be used as the cloning mas-ter. The following describes how to enter the password.3. How to enter the password with the keypad;If you press a key while “CLN LOCK” is displayed, thenumber that was pressed is displayed on the transceiver.Each press of the key shifts the display in order to the left.When you enter the password and press the * or S key,“CLONE” is displayed if the entered password is correct.If the password is incorrect, “CLN LOCK” is redisplayed.REALIGNMENTTK-21705How to enter the password with the selector;If the selector is rotated while “CLN LOCK” is displayed,numbers (0 to 9) are displayed flashing. When you pressthe C key, the currently selected number is determined.If you press the S key after entering the password in thisprocedure, “CLONE” is displayed if the entered passwordis correct. If the password is incorrect, “CLN LOCK” isredisplayed.4. Power on the slave transceiver.5. Connect the cloning cable (part No. E30-3410-05) to theSP/MIC connectors on the master and slave.6. Press the S key on the master while the master displays“CLONE”. The data of the master is sent to the slave.While the slave is receiving the data, “PROGRAM” is dis-played. When cloning of data is completed, the masterdisplays “END”, and the slave automatically operates inthe User mode. The slave can then be operated by thesame program as the master.7. The other slave can be continuously cloned. When the Skey on the master is pressed while the master displays“END”, the master displays “CLONE”. Carry out the op-eration in step 4 to 6.Notes:Cannot be cloned if the password (over write password) isprogrammed to the slave.Only the same models can be cloned together.REALIGNMENTCloning cable(E30-3410-05)Fig. 28-2. Adding a Data PasswordIf a data password is set in the optional feature menu, youmust enter the password to activate self-programmingmode.The password can consist of 6 digits, ranging from 09. To enter the password using the keypad:1. Press a key while “SLF.LOCK.R” or “SLF.LOCK.W” isdisplayed. The number that was pressed will appear onthe display.2. Each press of the key shifts the display in order to the left.3. When you have entered the entire password, press the* or S key. “SELF” appears on the display if the en-tered password is correct. If the password is incorrect,“SLF.LOCK.R” or “SLF.LOCK.W” is redisplayed. To enter the password using the selector:1. Rotate the selector while “SLF.LOCK.R” or “SLF.LOCK.W” is displayed. A number (0 to 9) will appear on thedisplay and flash.2. Press the C key. The currently selected number is set.3. When you have entered the entire password, press the Skey. “SELF” appears on the display if the entered pass-word is correct. If the password is incorrect, “SLF.LOCK.R” or “SLF.LOCK.W” is redisplayed.Note: Self-programming mode cannot be set when it has beendisabled by the FPU.Self-programming modeC + Power onFunction settingmodeChannel selectmodeZone selectmodeSide1 Side2AChannel editmodeZone editmodeC C8. Self-Programming ModeThis mode allows you to write the frequency data and sig-naling, etc. to the equipment.
