5-3. KPG-46/KPG-46A description
(PC programming interface cable: Option)
The KPG-46/46A is required to interface the transceiver
to the computer. It has a circuit in its D-sub connector (KPG-
46: 25-pin, KPG-46A: 9-pin) case that converts the RS-232C
logic level to the TTL level.
The KPG-46/46A connects the 8-pin microphone connec-
tor of the transceiver to the RS-232C serial port of the com-
puter.
5-4. KCT-53U description (USB adapter: Option)
The KCT-53U is a cable which connects the KPG-46A to
a USB port on a computer.
When using the KCT-53U, install the supplied CD-ROM
(with driver software) in the computer. The KCT-53U driver
runs under Windows 2000, XP or Vista (32-bit).
5-5. Programming software KPG-111D(C) description
The KPG-111D(C) is the programming software for the
transceiver supplied on a CD-ROM. This software runs un-
der Windows 2000, XP or Vista (32-bit) on a PC.
The data can be input to or read from the transceiver and
edited on the screen. The programmed or edited data can
be printed out. It is also possible to tune the transceiver.
6. Firmware Programming Mode
6-1. Preface
Flash memory is mounted on the transceiver. This al-
lows the transceiver to be upgraded when new features
are released in the future. (For details on how to obtain the
fi rmware, contact Customer Service.)
6-2. Connection procedure
Connect the transceiver to the personal computer using
the interface cable (KPG-46/46A) and USB adapter (KCT-53U:
when the interface cable is KPG-46A, the KCT-53U can be
used.). (Connection is the same as in the PC Mode.)
Note:
You can only program firmware from the 8-pin micro-
phone connector on the front panel. Using the 25-pin logic
interface on the rear panel will not work.
6-3. Programming
1. Start up the firmware programming software (Fpro.
exe (ver. 4.0 or later)). The Fpro.exe exists in the KPG-
111D(C) installed folder.
2. Set the communications speed (normally, 115200 bps)
and communications port in the confi guration item.
3. Set the fi rmware to be updated by File name item.
4. Turn the transceiver power ON with the [ ] key held
down. Then, the orange LED on the transceiver lights
and "PROGRAM 115200" is displayed.
5. Check the connection between the transceiver and the
personal computer, and make sure that the transceiver is
in the Program mode.
6. Press "write" button in the window. When the trans-
ceiver starts to receive data, the [LOADING] display
lights.

5-3. KPG-46/KPG-46A 说明
(PC 编程接口电缆 : 选购件 )
将 车 载 对 讲 机 连 接 到 电 脑 需 要 K P G -46/46A。 该 电 缆 的
D-sub 连接器 (KPG-46:25 针，KPG-46A:9 针 ) 盒具有将 RS-
232C 逻辑电平转换为 TTL 电平的电路。
K P G -46/46A 将车载对讲机的 8 针麦克风连接器连接到电脑
的 RS-232C 串行端口。
5-4. KCT-53U 说明 (USB 适配器 : 选购件 )
KCT-53U 是将 KPG-46A 连接到电脑 USB 端口的电缆。
使用 K C T -53U 时，请在电脑上安装附带的 C D - R O M ( 带有
驱动程序软件 )。KCT-53U 驱动程序在 Windows 2000、XP 或
Vista(32 位 ) 下运行。
5-5. 编程软件 KPG-111D(C) 说明
KPG-111D(C) 是 CD-ROM 附带的用于车载对讲机的编程软件。
该软件在 PC 的 Windows 2000、 XP 或 Vista(32 位 ) 下运行。
可在车载对讲机上写入或读取数据，并可在电脑屏幕上进
行编辑。可以打印编程或编辑的数据。此外，还可调谐车载
对讲机。
6. 固件编程模式
6-1. 前言
闪存安装在车载对讲机上。将来发布新功能时，可以使车
载对讲机进行升级。( 有关如何获得固件的详情，请洽询客户
服务机构。)
6-2. 连接操作
用接口电缆 (KPG-46/46A) 和 USB 适配器 (KCT-53U: 接口电
缆为 KPG-46A 时，可以使用 KCT-53U) 将车载对讲机连接到个
人电脑。( 连接方式与 PC 模式下相同。)
注意 ：
您只能通过前面板的 8 针麦克风连接器对固件进行编程。
使用后面板的 25 针逻辑接口进行编程时不起作用。
6-3. 编程
1. 启动固件编程软件 (Fpro.exe(ver.4.0 或更高版本 ))。
Fpro.exe 存在于 KPG-111D(C) 安装文件夹内。
2. 在配置项中设置通信速度 ( 通常为 115200 bps) 和通信端
口。
3. 通过文件名项目设置要更新的固件。
4. 打开车载对讲机电源时，按住 [ ] 键。然后，车载对讲机
上的橙色 LED 点亮，并显示"PROGRAM 115200" 。
5. 检查车载对讲机与个人电脑之间的连接，确认车载对讲机
处于编程模式。
6. 按窗口中的"w r i t e"按钮。车载对讲机开始接收数据时，
显示 [LOADING]。
