2.2.3 PC Mode
2.2.3.1 Preface
The transceiver is programmed by using a personal computer, a
programming interface (KPG-22A/22U) and the FPU (program-
ming 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-22U driver in the computer to
use the USB programming interface cable (KPG-22U).
(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.
When data is transmitting from the transceiver, the red LED
lights.
When data is being received by the transceiver, the green
LED lights.
Note:
• The data stored in the computer must match the "Mod-
el Name and Model Type" when it is written into the
EEPROM.
• Do not press the [PTT] key during data transmission or
reception.

2.2.3.3 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 (KPG-22A: 9-pin)
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.
2.2.3.4 KPG-22U description (USB programming interface
cable: Option)
The KPG-22U is a cable which connects to a USB port on a com-
puter.
When using the KPG-22U, install the supplied CD-ROM (with
driver software) in the computer. The KPG-22U driver runs under
Windows XP, Vista, 7, 8 or 8.1.
The latest version of the USB driver is available for download
from the following URL:

2.2.3.5 Programming software description
The FPU is the programming software for the transceiver sup-
plied on a CD-ROM. This software runs under Windows XP, Vis-
SP
ta, 7, 8 or 8.1 on a PC. The software on this disk allows a user to
program the transceiver via the Programming interface cable
MIC
(KPG-22A/22U).
• Use the FPU that matches the market when you first set the
market code and model name/frequency data to the service
unit. A unit set by mistake cannot be restored.

2.2.3.6 Programming with a PC
If data is transferred to the transceiver from a PC with the FPU,
the data for each set can be modified.
Data can be programmed into the EEPROM in RS-232C format
via the SP/MIC jack.
In this mode, the PTT line operate as TXD and RXD data lines,
respectively.
