3-1. Preface
The TK-2207 transceiver is programmed using a personal
computer, a programming interface (KPG-22) and programming
software (KPG-87D).
The programming software can be used with an IBM PC
or compatible. Figure 1 shows the setup of an IBM PC for
programming.
3-2. Connection procedure
1. Connect the TK-2207 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 transmitting from the transceiver, the red
LED lights.
When data is received by the transceiver, the green LED lights.
Notes:
· The data stored in the personal computer must match the
model type when it is written into the EEPROM.
· Change the TK-2207 to PC mode, then attach the interface
cable.
3-3. KPG-22 description
(PC programming interface cable: Option)
The KPG-22 is required to interface the TK-2207 with 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 side panel connector of the TK-
2207 to the computer's RS-232C serial port.
3-4. Programming software description
KPG-87D is the programming software for TK-2207
supplied on a CD-ROM. This software runs under Windows
98, ME, Windows 2000 or XP on an IBM-PC or compatible
machine.
The data can be input to or read from TK-2207 and edited
on the screen. The programmed or edited data can be printed
out. It is also possible to tune the transceiver.

4. Clone Mode
4-1. Outline
"Clone Mode" copies the transceiver data to another
transceiver.
The dealer can copy the transceiver data to another
transceiver even without the use of a personal computer.
4-2. Example
The transceiver can copy the programming data to one or
more transceivers via RF communication.
The clone master and clone slave/s must be in Clone mode.
4-3. Operation
1. To switch the clone slave/s to Clone mode, press and hold
the [PTT] and [side2] keys while turning the transceiver
power ON.
2. Wait for 2 seconds. The LED will light orange and the
transceiver will announce "Clone".
3. Select a channel table number using Side1(increment
channel table) and Side2(decrement channnel table) keys.
4. To switch the clone master to Clone mode, press and hold
the [PTT] and [side2] keys while turning the transceiver
power ON.
5. Wait for 2 seconds. The LED will light orange and the
transceiver will announce "Clone".
6. Select the same channel table number as the clone slave/s.
7. Press [PTT] on the clone master to begin data transmission.
When the clone slave starts to receive data, the LED will
light green.
When the clone master finishes sending data, a
"confirmation" tone will sound.
If data transmission fails while cloning, an "error" tone will
sound from the Slave unit.
