3-1. Preface
The transceiver is programmed by using a personal com-
puter, a programming interface (KPG-22A/22U, USB adapter
(KCT-53U)) and programming software (KPG-137D: ver.1.10
or later).
The programming software can be used with a PC. Fig-
ure 1 shows the setup of a PC for programming.
3-2. Connection Procedure
1. Connect the transceiver to the personal computer with
the interface cable and USB adapter (when the interface
cable is KPG-22A, the KCT-53U can be used).
Note:
• You must install the KPG-22U driver in the computer to
use the USB programming interface cable (KPG-22U).
• You must install the KCT-53U driver in the computer to
use the USB adapter (KCT-53U).
• When using the USB adapter (KCT-53U) for the first time,
plug the KCT-53U into a USB port on the computer with
the computer power ON.
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.
When data is read from the transceiver, the red LED
lights.
When data is written to by the transceiver, the green LED
lights.
Note:
• The data stored in the personal computer must match
Model Name and Model Type when it is written into EE-
PROM.
• Do not press the [PTT] key during data transmission or
reception.
3-3. KPG-22A Description
(PC programming interface cable: Option)
The KPG-22A is required to interface the transceiver with
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.
3-4. KPG-22U Description
(USB programming interface cable: Option)
The KPG-22U is a cable which connects to a USB port
on a computer.

4. Clone Mode
Programming data can be transferred from one trans-
ceiver to another by connecting them via their SP/MIC con-
nectors.
Cloning can be performed as described below (the trans-
mit transceiver is the source and the receive transceiver is
the target).
The following data cannot be cloned.
• Tuning data
• Model name data
• ESN data
1. Turn the source transceiver and target transceiver power
OFF.
2. Turn the source transceiver power ON while pressing the
[PTT] and [Side] keys, to enter clone mode.
3. Connect the cloning cable (part No. E30-3410-05) to the
SP/MIC connectors on the source and target transceiv-
ers.
4.Turn the target transceiver power ON.
5. Press the [Side] key on the source transceiver.The data of
the source is sent to the target.While the source is send-
ing data, red LED will light. While the target is receiving
the data, green LED will light. When cloning of data is
completed, the source red LED turned off, and the target
automatically operates in the User mode.
6. Additional targets can be continuously cloned. When
the [Side] key on the source is pressed, the data of the
source is sent to the target again. Repeat steps 3 to 5 to
clone additional transceivers.
