3-1. Preface
The TK-3207 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-3207 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-3207 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-3207 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.

REALIGNMENT /
The KPG-22 connects the side panel connector of the TK3207 to the computer’s RS-232C serial port.
3-4. Programming software description
KPG-87D is the programming software for TK-3207 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-3207 and edited on the screen. The programmed or edited data can be printed
out. It is also possible to tune the transceiver.

|
transceiver. |
|
“ ” |
The dealer can copy the transceiver data to another |
|
|
transceiver even without the use of a personal computer. |
|
|
4-2. Example |
|
4-2 : |
The transceiver can copy the programming data to one or |
RF |
|
more transceivers via RF communication. |
|
|
The clone master and clone slave/s must be in Clone mode. |
|
|
4-3. Operation |
|
4-3 |
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.

REALIGNMENT /
8.If the cloning fails, no data will be available in the Slave unit when it is returned to User mode.
9.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).
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.
•A unit cannot be a "Master Unit" if it is unprogrammed. If [PTT] is pressed, an "error" tone will sound.
•The language used in cloning depends on the "Model type" setting, not the FPU setting. C, C2, C5 and C6 type TK-3207 transceivers will use Chinese. Other types English.
•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.
•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.
