2.2.3 PC Mode
2.2.3.1 Preface
The transceiver is programmed using a personal computer, a
programming interface (KPG-46A/46U) and FPU (programming
software).
The programming software can be used with a PC. Figure 1
shows the setup of a PC for programming.

2.2.3.2 Connection procedure
(1) Connect the transceiver to the computer using the interface
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, you can immediately enter
user mode. When the PC sends a command, the transceiv-
er enters PC mode, and "Pc" is displayed on the LED.
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.
2.2.3.3 KPG-46A description
(PC programming interface cable: Option)
The KPG-46A is required to interface the transceiver to the com-
puter. 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 computer.
2.2.3.4 KPG-46U description
(USB programming interface cable: Option)
The KPG-46U is a cable which connects to a USB port on a com-
puter.
When using the KPG-46U, install the supplied CD (with driver
software) in the computer. The KPG-46U driver runs under Win-
dows XP, Vista, 7 or 8.
The latest version of the USB driver is available for download

2.2.3.5 Programming Software: KPG-175D description
The FPU is the programming software for the transceiver sup-
plied on a CD. This software runs under Windows XP, Vista, 7 or
8 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.
2.2.4 Clone Mode
Programming data can be transferred from one transceiver to an-
other by connecting them via their cloning cable. The operation
is as follows (the transmit transceiver is the source and the re-
ceive transceiver is a target).
Note:
Clone mode should be enabled.
(1) Turn the source transceiver power ON with the [ ] key held
down (2 seconds), "cL" is displayed on the LED.
(2) Power on the target transceiver.
(3) Connect the cloning cable (No. E30-3382-05) to the modu-
lar microphone jacks on the source and target.
(4) Press the [S] key on the source transceiver.
The data of the source is sent to the target. While the
source is sending data, red LED blinked.
While the target is receiving the data, "Pc" is displayed and
green LED blinked. When cloning of data is completed, the
source displays "En", and the source red LED turned off,
and the target automatically operates in the User mode.
The target can then be operated by the same program as
the source.
(5) The other target can be continuously cloned. Carry out the
operation in step 2 to 4.
2.2.4.1 Adding the data password.
If the data password is set in the optional feature menu, you must
enter the password (Source transceiver) to activate a clone
mode.
You can use 0~9 to configure the password. The maximum
length of the password is 6 digits.
(1) [ ]+Power ON.
(2) "PS" is displayed on the LED.
(3) If the [ ] and [ ] keys is pressed while "PS" is displayed,
numbers (0 to 9) are displayed flashing. When you press
the [C>] key, the currently selected number is determined.
If you press the [S] key after entering the password in this
procedure, "cL" is displayed if the entered password is cor-
rect. If the password is incorrect, "PS" is redisplayed.
