5-2. Connection procedure
1. Connect the transceiver to the computer using the inter-
face cable.
Note:
• You must install the KPG-46U driver in the computer to
use the USB programming interface cable (KPG-46U).
2. When the Power is switched on, user mode can be en-
tered immediately. When the PC sends a command, the
transceiver enters PC mode, and “PROGRAM” is dis-
played on the LCD.
When data is transmitting from the transceiver, the red
LED blinks.
When data is receiving by the transceiver, the green LED
blinks.
Note:
The data stored in the computer must match the “Model
Name” when it is written into the EEPROM.
5-3. KPG-46A description
(PC programming interface cable: Option)
The KPG-46A is required to interface the transceiver to
the computer. It has a circuit in its D-sub connector (KPG-46A:
9-pin) case that converts the RS-232C logic level to the TTL
level.
The KPG-46A connects the 8-pin microphone connector
of the transceiver to the RS-232C serial port of the comput-
er.
5-4. KPG-46U description
(USB programming interface cable: Option)
The KPG-46U is a cable which connects to a USB port
on a computer.
When using the KPG-46U, install the supplied CD-ROM
(with driver software) in the computer. The KPG-46U driver
runs under Windows XP, Vista or 7.
The latest version of the USB driver is available for down-
load from the following URL:
http//www.kenwood.com/usb-com/
(This URL may change without notice.)
5-5. Programming Software : KPG-141D
(ver.3.00 or later) description
The FPU is the programming software for the transceiver
supplied on a CD-ROM. This software runs under 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 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 in-
stalled holder.
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.
