5-3. KPG-22A description
(PC programming interface cable: Option)
The KPG-22A is required to interface the transceiver to
the computer. It has a circuit in its D-sub connector case
that converts the RS-232C logic level to the TTL level.
The KPG-22A connects the SP/MIC connector of the
transceiver to the RS-232C serial port of the computer.
5-4. KPG-22U description
(USB programming interface cable: Option)
The KPG-22U is a cable which connects to a USB port on
a computer.
When using the KPG-22U, install the supplied CD-ROM
(with driver software) in the computer. The KPG-22U driver
runs under Windows XP, Vista or 7.
5-5. KCT-53U description (USB adapter: Option)
The KCT-53U is a cable which connects the KPG-22A 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).
5-6. Programming software KPG-141D(C) description
The KPG-141D(C) is the programming software for the
transceiver supplied on a CD-ROM. This software runs un-
der Windows XP, Vista or 7 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 allows
the transceiver to be upgraded when new features are re-
leased in the future. (For details on how to obtain the fi rm-
ware, contact Customer Service.)
6-2. Connection procedure
Connect the transceiver to the personal computer using
the interface cable (KPG-22A/22U) and USB adapter (KCT-
53U: when the interface cable is KPG-22A, the KCT-53U can
be used.). (Connection is the same as in the PC Mode.)
6-3. Programming
1. Start up the firmware programming software (Fpro.exe
(ver. 6.0 or later)). The Fpro.exe exists in the KPG-141D(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. Press and hold the [Side1] key while turning the trans-

有驱动程序 )。K C T -53U 驱动程序在 W i n d o w s 2000,X P 或
Vista(32 位 ) 下运行。
5-6. 编程软件 KPG-141D(C) 说明
KPG-141D(C) 是 CD-ROM 附带的用于手持对讲机的编程软件。
该软件在 PC 的 Windows XP, Vista 或 7 下运行。
可在手持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,还可调谐手持
对讲机。
6. 固件编程模式
6-1. 前言
闪存安装在手持对讲机上。将来发布新功能时,可以使手
持对讲机进行升级。( 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-22A/22U) 和 USB 适配器 (KCT-53U: 接口
电缆为 KPG-22A 时,可以使用 KCT-53U) 将手持对讲机连接到
个人电脑。( 连接方式与 PC 模式下相同。)
6-3. 编程
1. 启动固件编程软件 ( F p r o . e x e ( v e r .6.0 或更高版本 ) )。
Fpro.exe 存在于 KPG-141D(C) 安装文件夹内。
2. 在配置项中设置通信速度 ( 通常为 115200 b p s ) 和通信端
口。
3. 通过文件名项目设置要更新的固件。
