5-1. Preface
The TK-280 transceiver is programmed by using a personal
computer, programming interface (KPG-36) and programming
software (KPG-49D).
The programming software can be used with an IBM PC or
compatible. Figure 1 shows the setup of an IBM PC for
programming.
5-2. Connection procedure
1. Connect the TK-280 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 radio enter PC
mode, and "PROGRAM" is displayed on the LCD.
When data transmitting from transceiver, the red LED is
blinking.
When data receiving to transceiver, the green LED is blinking.
Notes:
• The data stored in the personal computer must match model
type, when it is written into the flash memory.
• Change the TK-280 to PC mode, then attach the interface
cable.
5-3. KPG-36 description
(PC programming interface cable: Option)
The KPG-36 is required to interface the TK-280 to the
computer. It has a circuit in its D-subconnector (25-pin) case
that converts the RS-232C logic level to the TTL level.
The KPG-36 connects the universal connector of the TK-
280 to the computers RS-232C serial port.
5-4. Programming software description
The KPG-49D programming disk is supplied in 3-1/2" disk
format. The software on this disk allows a user to program TK-
280 radios via programming interface cable (KPG-36).

5-5. Programming with IBM PC
If data is transferred to the transceiver from an IBM PC with
the KPG-49D, the destination data (basic radio information)
for each set can be modified. Normally, it is not necessary to
modify the destination data because their values are
determined automatically when the frequency range (frequency
type) is set.
The values should be modified only if necessary. Data can
be programmed into the flash memory in RS-232C format via
the universal connector.

6. Firmware Programming Mode
6-1. Preface
Flash memory is mounted on the TK-280. This allows the
TK-280 to be upgraded when new features are released in the
future. (For details on how to obtain the firmware, contact
Customer Service.)
6-2. Connection procedure
Connect the TK-280 to the personal computer (IBM PC or
compatible) with the interface cable (KPG-36). (Connection is
the same as in the PC Mode.)
6-3. Programming
1. Start up the programming software (KPG-49D), select
"firmware program" in the "Program" item, and press the
Return key on the personal computer. This starts up the
firmware programmer.
2. The top screen is displayed. Press any key to advance to
the 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-280 power ON with the [S] switch held down.
Hold the switch down for two seconds until the display
changes to "PROG 57600". When "PROG 57600" appears,
release your finger from the switch.
6. Check the connection between the TK-280 and the personal
computer, and make sure that the TK-280 Is in the Program
mode.
7. Press F10 on the personal computer. A window opens on
the display to indicate progress of writing. When the TK-
