8TK-480 REALIGNMENT1. PC Mode1-1. PrefaceThe TK-480 transceiver is programmed by using a per-sonal computer, programming interface (KPG-36) and pro-gramming software (KPG-49D (M2) ver 6.30 or later).The programming software can be used with an IBM PCor compatible. Figure 1 shows the setup of an IBM PC forprogramming.1-2. Connection procedure1. Connect the TK-480 to the personal computer with theinterface 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 isblinking.When data receiving to transceiver, the green LED isblinking.Notes:• The data stored in the personal computer must matchmodel type, when it is written into the flash memory.• Change the TK-480 to PC mode, then attach the interfacecable.1-3. KPG-36 description(PC programming interface cable: Option)The KPG-36 is required to interface the TK-480 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-36 connects the universal connector of the TK-480 to the computers RS-232C serial port.1-4. Programming software descriptionThe KPG-49D (M2) ver 6.30 or later programming disk issupplied in 3-1/2" disk format. The software on this disk al-lows a user to program TK-480 radio via programming inter-face cable (KPG-36).1-5. Programming with IBM PCIf data is transferred to the transceiver from an IBM PCwith the KPG-49D (M2) ver 6.30 or later, the destination data(basic radio information) for each set can be modified. Nor-mally, it is not necessary to modify the destination data be-cause their values are determined automatically when thefrequency range (frequency type) is set.The values should be modified only if necessary. Datacan be programmed into the flash memory in RS-232C for-mat via the universal connector.KPG-49D (M2) instruction manual parts No. : B62-1358-XX2. Firmware Programming Mode2-1. PrefaceFlash memory is mounted on the TK-480. This allows theTK-480 to be upgraded when new features are released inthe future. (For details on how to obtain the firmware, con-tact Customer Service.)2-2. Connection procedureConnect the TK-480 to the personal computer (IBM PC orcompatible) with the interface cable (KPG-36). (Connectionis the same as in the PC Mode.)2-3. Programming1. Start up the programming software (KPG-49D (M2) ver6.30 or later), select “firmware program” in the “Pro-gram” item, and press the Return key on the personalcomputer. This starts up the firmware programmer.2. The top screen is displayed. Press any key to advance tothe next screen.3. Set the communications speed (normally, 57600 bps)and communications port in the Setup item.4. Set the firmware to be updated by File select (=F1).5. Turn the TK-480 power ON with the [S] switch helddown. Hold the switch down for two seconds until thedisplay changes to “PROG 57600”. When “PROG57600” appears, release your finger from the switch.6. Check the connection between the TK-480 and the per-sonal computer, and make sure that the TK-480 is in theProgram mode.7. Press F10 on the personal computer. A window opens onthe display to indicate progress of writing. When the TK-480 start to receive data. the [P] icon is blinking.8. If writing ends successfully, the LED on the TK-480 lightand the checksum is displayed.9. If you want to continue programming other TK-480, re-peat steps 5 to 8.Fig. 1KPG-36IBM-PCKPG-49D (M2)(ver 6.30 or later)
