4-1. Preface
The transceiver is programmed using a personal computer,
a programming interface (KPG-22/22A), USB adapter (KCT-53U)
and programming software (KPG-90D).
The programming software can be used with an IBM PC
or compatible. Figure 1 shows the setup of an IBM PC for
programming.
4-2. 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.).
Notes:
•
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
entered immediately. When the PC sends a command,
the transceiver enters PC mode.
When data is transmitting from the transceiver, the red
LED lights.
When data is received by the transceiver, the green LED
lights.
Notes:
• The data stored in the computer must match the model
type when it is written into the EEPROM.
• Change the transceiver to PC mode, then attach the
interface cable.
4-3. KPG-22/KPG-22A description
(PC programming interface cable: Option)
The KPG-22/22A is required to interface the transceiver with
the computer. It has a circuit in its D-sub connector (KPG-22 :
25-pin, KPG-22A : 9-pin) case that converts the RS-232C logic
level to the TTL level.
The KPG-22/22A connects the SP/MIC connector of the
transceiver to the RS-232C serial port of the computer.

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 or XP.

KPG-90D is the programming software for the transceiver
supplied on a CD-ROM. This software runs under Windows
98, ME, Windows 2000 or XP on an IBM-PC or compatible
machine.
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.

CIRCUIT DESCRIPTION
TK-3201
1. Control Circuit
The control circuit consists of a microprocessor (IC405) and
its peripheral circuits. It controls the TX-RX unit. IC405 mainly
performs the following:
(1) Switching between transmission and reception by the
PTT signal input.
(2) Reading system, group, frequency, and program data
from the memory circuit.
(3) Sending frequency program data to the PLL.
(4) Controlling squelch on/off by the DC voltage from the
squelch circuit.
(5) Controlling the audio mute circuit by the decode data
input.
(6) Transmitting tone and encode data.
1) Frequency Shift Circuit
The microprocessor (IC405) operates at a clock of
7.3728MHz. This oscillator has a circuit that shifts the
frequency by BEAT SHIFT SW (Q407,Q408).
A beat sound may be able to be evaded from generation if
“Beat Shift” is set to ON when it is generated in the internal
spurious transmission modulated sound of a transceiver.

(2) The transceiver immediately stops transmission when
the battery voltage falls below the voltage (2) shown in
the table. The warning tone sounds while the PTT
switch is pressed.

2) Memory Circuit
Memory circuit consists of the CPU (IC405) and an EEPROM
(IC406). An EEPROM has a capacity of 8k bits that contains
the transceiver control program for the CPU and data such
as transceiver channels and operating features.

3) Low Battery Warning
The battery voltage is checked using by the microprocessor.
The transceiver generates a warning tone when the battery
voltage falls below the warning voltage (2) shown in the table.
(1) The red LED blinks when the battery voltage falls below
the voltage (1) shown in the table during transmission.
Note:
During reception, transceiver constantly checks the battery
level. When the battery level drops near to 5.9V, the red
LED blinks and low battery warning tone is generated.
