5. PC Mode
5-1. Preface
The TK-272G transceiver is programmed using a personal
computer, a programming interface (KPG-22) and
programming software (KPG-56D).
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-272G to the personal computer with the
interface cable.
2. When the POWER is switched on, user mode can be
entered immediately. When the PC sends a command,
the radio enters PC mode.
When data is transmitted from transceiver, the red LED blinks.
When data is received by the transceiver, the green LED blinks.
Notes:
•
The data stored in the personal computer must match the
model type when it is written into the flash memory.
•
Change the TK-272G to PC mode, then attach the interface
cable.

REALIGNMENT
5-3. KPG-22 description
(PC programming interface cable: Option)
The KPG-22 is required to interface the TK-272G 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-22 connects the SP/MIC connector of the TK-
272G to the computers RS-232C serial port.
5-4. Programming software description
The KPG-56D programming disk is supplied in 3-1/2” disk
format. The software on this disk allows a user to program the TK-
272G radios via a programming interface cable (KPG-22).
5-5. Programming with IBM PC
If data is transferred to the transceiver from an IBM PC
with the KPG-56D, 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-272G. This allows the
TK-272G 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-272G to the personal computer (IBM PC
or compatible) with the interface cable (KPG-22). (Connection
is the same as in the PC Mode.)
6-3. Programming
1. Start up the programming software (KPG-56D), select
"firmware program" in the "Program" item, and press the
Return key on your 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. Hold down the [Side1] and [Side2] switches on the TK-272G,
and press the power switch.
When the [Side1] and [Side2] switches are held down for
two seconds, "PROG576" appears on the display and
the LED lights orange. When "PROG576" is displayed,
release the switches .
6. Check the connection between the TK-272G and the
personal computer, and make sure the TK-272G is in
Program mode.
7. Press F10 on the personal computer. A window opens on
the display to indicate the writing progress. When the TK-
272G begins to receive data, the LED lights green.
8. When data is received successfully, a checksum appears
on the display.
9. If you want to continue programming other TK-272Gs,
repeat steps 5 to 8.
