NX-30045-2. Connection procedure1. Connect the transceiver to the computer using the inter-face cable and USB adapter (When the interface cable isKPG-36A, the KCT-53U can be used.).Notes:• You must install the KCT-53U driver in the computer touse the USB adapter (KCT-53U).• When using the USB adapter (KCT-53U) for the first time,plug the KCT-53U into a USB port on the computer withthe computer power ON.2. When the POWER switch on, user mode can be enteredimmediately. When PC sends command the transceiverenter PC mode, and “PROGRAM” is displayed on 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 computer must match the "ModelName" when it is written into the flash memory.5-3. KPG-36/KPG-36A description(PC programming interface cable: Option)The KPG-36/36A is required to interface the transceiver tothe computer. It has a circuit in its D-sub connector (KPG-36: 25-pin, KPG-36A : 9-pin) case that converts the RS-232Clogic level to the TTL level.The KPG-36/36A connects the universal connector of thetransceiver to the RS-232C serial port of the computer.5-4. KCT-53U description (USB adapter : Option)The KCT-53U is a cable which connects the KPG-36A to aUSB port on a computer.When using the KCT-53U, install the supplied CD-ROM(with driver software) in the computer. The KCT-53U driverruns under Windows 2000 or XP.5-5. Programming software KPG-111D descriptionThe KPG-111D is the programming software for the trans-ceiver supplied on a CD-ROM. This software runs under MS-Windows 2000 or XP on an IBM-PC or compatible 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) using the interface cable (KPG-36/36A) andUSB adapter (KCT-53U : when the interface cable is KPG-36A, the KCT-53U can be used.). (Connection is the same asin the PC Mode.)6-3. Programming1. Start up the firmware programming software (Fpro.exe(version 4.0 or later))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. Press and hold the [ ] key while turning the transceiverpower ON. Then, the orange LED on the transceiver lightsand “PROGRAM 115200” 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 trans-ceiver starts to receive data, the [LOADING] display lights.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.Note:This mode cannot be entered if the Firmware Program-ming mode is set to Disable in the Programming software.6-4. Function1. If you press the [Side2] key while “PROGRAM 115200” isdisplayed, the display changes to “PROGRAM 19200”(The LED blinks green) to indicate that the write speed islow speed (19200 bps). If you press the [Side2] key againwhile “PROGRAM 19200” is displayed, the displaychanges to “PROGRAM 38400” (The LED lights red andorange alternatively). If you press the [Side2] key againwhile “PROGRAM 38400” is displayed, the displaychanges to “PROGRAM 57600” (The LED blinks orange).If you press the [Side2] key again while “PROGRAM57600” is displayed, the display returns to “PROGRAM115200” (The LED lights orange).2. If you press the [Side1] key while “PROGRAM 115200” isdisplayed, the checksum is calculated, and a result is dis-played. If you press the [Side1] key again while thechecksum is displayed, “PROGRAM 115200” isredisplayed.Note:Normally, write in the high-speed mode.7. Clone ModeProgramming data can be transferred from one transceiverto another by connecting them via their external universal con-nectors. The operation is as follows (the transmit transceiver isthe source and the receive transceiver is a target).The following data cannot be cloned.• Tuning data• Embedded message with password• Model name data• ESN (Electronic Serial Number) dataREALIGNMENT
