3-1. Preface
The TK-2212/2217 transceivers are programmed using a
personal computer, a programming interface (KPG-22) and
programming software (KPG-100D).
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-2212/2217 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 transceiver enters PC mode. In the PC mode,
"PROGRAM" is displayed on the LCD.
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-2212/2217 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-2212/2217 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 SP/MIC connector of the TK-2212/
2217 to the computer’s RS-232C serial port.
3-4. Programming software description
KPG-100D is the programming software for TK-2212/2217
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-2212/2217 and
edited on the screen. The programmed or edited data can be
printed out. It is also possible to tune the transceiver.

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 [<B] key while turning the transceiver power ON.
2. Wait for 2 seconds. “CLONE” appears on the LCD, followed
by “FRQTBL 1”.
3. Select a channel table number using the [Selector] knob.
4. To switch the clone master to Clone mode, press and hold
the [<B] key while turning the transceiver power ON.
5. Wait for 2 seconds. “CLONE” appears on the LCD, followed
by “FRQTBL 1”.
6.
Select the same channel table number as the clone slave/s.
7. Press the [S] key on the clone master to begin data
transmission. When the clone slave starts to receive data,
the green LED will light and “CLONING” will appear on
the LCD. The master unit will display “MASTER”.
8. When the clone master finishes sending data, a
“confirmation” tone will sound and “COMPLETE” will
appear on the LCD. If data transmission failed while cloning,
the Slave unit will produced an error tone and “CLONE
NG” will appear on the LCD.
9. If the cloning fails, no data will be available in the Slave unit
when it is returned to User mode.
10.When the cloning is successful, the Slave unit's "Scan" and
"Key lock" functions will return to their default values (Scan
= OFF, Key lock = OFF).
11.The master will remain in clone mode after cloning. The
slave unit will return to user mode after a successful cloning.
Notes:
•The dealer can clone data to two or more transceivers by
repeating the above procedures.
•If the transceivers Clone Mode is configured as "Disabled",
the transceiver cannot enter Clone mode.
•The table shown below will cover the frequency tables used
for wireless cloning.
•Clone mode cannot be entered in battery low state.
•Aunit cannot be a "Master Unit" if it is unprogrammed. If
the [S] key is pressed, an "error" tone will sound.
•Once a unit is set to be the Master, it cannot be a slave
after the data has been transmitted. This protects the data
in the Master unit.
•MSK signaling is used in cloning.
•Electronic interface may cause a failure in data transfer
during Wireless Clone, such as when waveforms or
electromagnetics are being performed at the workbench.
•Clone mode can be used ONLY by the authorized service
personnel.
•The Clone mode setting must be configured as "Disable"
before being delivered to the end-user.
•To clone, replace the antenna from both the master
transceiver and the slave transceiver with a dummy
load.
•The transmit output power is automatically set to Low
in Clone mode.
