NX-820
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 rm-
ware, contact Customer Service.)
6-2. Connection procedure
Connect the transceiver to the personal computer using
the interface cable (KPG-46A/46U). (Connection is the same
as in the PC Mode.)
6-3. Programming
1. Start up the fi rmware programming software (Fpro.exe (ver.
6.1 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 [ ] key while turning the transceiver
power ON. Then, the orange LED on the transceiver
lights and "FIRM PRG" 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 transceiver
starts to receive data, the "LOADING" display lights.
7. If writing ends successfully, the checksum is calculated
and a result is displayed.
8. If you want to continue programming other transceivers,
repeat steps 4 to 7.
6-4. Function
If you press the [
]
the checksum is calculated, and a result is displayed.If you
press the [ key again while the checksum is displayed,
]
"FIRM PRG" is redisplayed.
Note:
• This mode cannot be entered if the Firmware Program-
ming mode is set to Disable in the Programming soft-
ware.
• Normally, write in the high-speed mode.

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 ( KP G-46A/46U ) 将车载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 (Fpro.exe (ver.6.1 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 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 [
机上的橙色 LED 点亮，并显示"FIRM PRG" 。
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"write"按钮。车载对讲机开始接收数据时，
显示"LOADING" 。
7. 如果写入操作成功完成，则计算校验和并显示结果。
8. 若要继续为其他车载对讲机编程，请重复步骤 4 至 7。
6-4. 功能
如果在显示"FIRM PRG"时按 [
显示结果。如果在显示校验和时再次按 [
"FIRM PRG" 。
注意 :
· 如果车载对讲机的固件编程模式设为禁用，则无法进入此
模式。
· 通常以高速模式写入。
