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. 计算机模式

3-1 前言

TK-3207 手持机使用计算机、编程接口（KPG-22）和编程软

件（KPG-87D）进行编程。

IBM 计算机或兼容机可以使用编程软件。图 1 显示 IBM 计算

机编程的设置。

3-2 连接步骤

1. 使用接口电缆将 TK-3207 连接到计算机上。

2. 当电源接通时，立即进入用户模式。当 PC 机发出指令时，手持机进入 PC 模式。当手持机传送数据时，红色指示灯闪动。当手持机传送数据时，绿色指示灯闪动。

注释：

• 当把储存在计算机中的数据写入到 EEPROM 中时, 机型型号

必须相匹配。

• 将 TK-3207 改变为计算机模式，然后连接接口电缆。

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.

3-3 KPG-22 说明(PC 机编程接口电缆∶可选件)

TK-3207 需要通过接口电缆 KPG-22与电脑连接。此接口电缆的D连接器（25 芯）中有一个将 RS-232C 逻辑电平转换为 TTL 电平的电路。

4. Clone Mode

Fig. 1 / 图１

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".

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.

4. 复制模式

4-1 概要

“复制模式”可以将一台手持机的数据复制到其它的手持机。

经销商甚至不使用个人电脑也可以将一台手持机的数据复制

到其它的手持机。

4-2 例:

手持机可以通过 RF 通信复制编程数据到一台或更多的手持

机。

复制主机和复制子机必须处于复制模式。

4-3 操作方法

1. 将子机切换到复制模式，旋转手持机电源的同时，持续按 [PTT] 键和 [侧 2] 键。

2. 等待 2秒。LED将呈橘黄色并且手持机将发出"复制"的声音。

3. 用侧 1 (频道表递增) 键和侧 2 (频道表递减) 键选择频道表号码。

4. 将主机切换到复制模式，旋转手持机电源的同时，持续按 [PTT] 键和 [侧 2] 键。

5. 等待 2秒。LED将呈橘黄色并且手持机将发出"复制"的声音。

6. 选择与复制子机相同的频道表号码。

7. 按复制主机上的 [PTT]，开始数据传输。当复制子机开始接收数据时，LED 将呈绿色。当复制主机完成传送数据时，将发出一个“确认”音。如果在复制过程中数据传输失败，子机将发出一个"错误"音。

8. 如果复制失败，子机回到用户模式时数据随即消失。

9. 当复制成功时，子机的 " 扫描 " 和 " 键锁定 " 功能将回到它们的初始值 (扫描 =OFF, 键锁定 =OFF)

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.

模式组合

注释：

• 经销商可以反复上述过程复制数据到 2 个或更多的手持机。

• 如果手持机复制模式被设置为“无效”，则手持机不能进入

复制模式。

• 下表包含了无线复制用的频率表。

• 当电池处于低电压状态时不能进入复制模式。

• 如果手持机是非编程的它将不能成为主机。如果按[PTT]，将

发出一个 " 错误 " 音。

• 复制时所用的语言是根据 "样机类别 "设置，而不是 FPU 设置，TK-3207 的C，C2，C5 和C6 类别的手持机用中文，其它类别用英文。

• 手持机一旦被设置为主机，数据传送以后，它就不能成为子机。这是为了保护主机里的数据。

• 在无线复制的数据传输过程中，例如在工作台产生的电波或电磁干扰有可能引起传输失败。

• 复制模式可以仅被批准的服务人员使用。

• 在交付给最终用户之前，复制模式设置必须被设置为“无

效”。

• 为了复制，将模拟负载代替主手持机和子手持机的天线。

• 在复制模式，发射功率自动设定为低。
