TK-480
1. PC Mode
1-1. Preface
The 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 PC
or compatible. Figure 1 shows the setup of an IBM PC for
programming.
1-2. Connection procedure
1. Connect the TK-480 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-480 to PC mode, then attach the interface
cable.
1-3. KPG-36 description
(PC programming interface cable: Option)
The KPG-36 is required to interface the TK-480 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-
480 to the computers RS-232C serial port.
1-4. Programming software description
The KPG-49D (M2) ver 6.30 or later programming disk is
supplied 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 PC
If data is transferred to the transceiver from an IBM PC
with 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 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 for-
mat via the universal connector.

2. Firmware Programming Mode
2-1. Preface
Flash memory is mounted on the TK-480. This allows the
TK-480 to be upgraded when new features are released in
the future. (For details on how to obtain the firmware, con-
tact Customer Service.)
2-2. Connection procedure
Connect the TK-480 to the personal computer (IBM PC or
compatible) with the interface cable (KPG-36). (Connection
is the same as in the PC Mode.)
2-3. Programming
1. Start up the programming software (KPG-49D (M2) ver
6.30 or later), select "firmware program" in the "Pro-
gram" 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-480 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-480 and the per-
sonal computer, and make sure that the TK-480 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-
480 start to receive data. the [P] icon is blinking.
8. If writing ends successfully, the LED on the TK-480 light
and the checksum is displayed.
9. If you want to continue programming other TK-480, re-
peat steps 5 to 8.
