2. When the POWER switch on, user mode can be entered
immediately. When PC sends command the transceiver
enter PC mode, and "PROGRAM" is displayed on the
LCD.
When data transmitting from transceiver, the red LED is
lights.
When data receiving to transceiver, the green LED is
lights.
Note:
The data stored in the computer must match the "Model
Name" when it is written into the fl ash memory.
5-3. KPG-46/KPG-46A description
(PC programming interface cable: Option)
The KPG-46/46A is required to interface the transceiver
to the computer. It has a circuit in its D-sub connector (KPG-
46: 25-pin, KPG-46A: 9-pin) case that converts the RS-232C
logic level to the TTL level.
The KPG-46/46A connects the 8-pin microphone connec-
tor of the transceiver to the RS-232C serial port of the com-
puter.
5-4. KCT-53U description (USB adapter: Option)
The KCT-53U is a cable which connects the KPG-46A 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.
5-5. Programming software KPG-92D description
The KPG-92D is the programming software for the trans-
ceiver supplied on a CD-ROM. This software runs under
MS-Windows 98, Me, Windows 2000, XP or Vista (32-bit)
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.
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 rmware, contact Customer Service.)
6-2. Connection procedure
Connect the transceiver to the personal computer (IBM
PC or compatible) using the interface cable (KPG-46/46A)
and USB adapter (KCT-53U: when the interface cable is
KPG-46A, the KCT-53U can be used.). (Connection is the
same as in the PC Mode.)
Note:
You can only program firmware from the 8-pin micro-
phone connector on the front panel. Using the 25-pin logic
interface on the rear panel will not work.
REALIGNMENT
6-3. Programming
1. Start up the fi rmware programming software (Fpro.exe
(ver. 4.02 or later)). The Fpro.exe exists in the KPG-92D
installed 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. Turn the transceiver power ON with the [S] key held
down. Then, the orange LED on the transceiver lights
and "PROG 115200" 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 [PG] display is blinking.
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.
Note:
This mode cannot be entered if the Firmware Program-
ming mode is set to Disable in the Programming soft-
ware.
6-4. Function
1. If you press the [ ■] key while "PROG 115200" is dis-
played, the display changes to "PROG 19200" (The
LED blinks green) to indicate that the write speed is
low speed (19200 bps). If you press the [■] key again
while "PROG 19200" is displayed, the display changes
to "PROG 38400" (The LED lights red and orange alter-
natively). If you press the [■] key again while "PROG
38400" is displayed, the display changes to "PROG
57600" (The LED blinks orange). If you press the [■]
key again while "PROG 57600" is displayed, the display
returns to "PROG 115200" (The LED lights orange).
2. If you press the [ ] key while "PROG 115200" is dis-
played, the checksum is calculated, and a result is dis-
played. If you press the [ ] key again while the check-
sum is displayed, "PROG 115200" is redisplayed.
Note:
Normally, write in the high-speed mode.
7. Clone Mode
Programming data can be transferred from one trans-
ceiver to another by connecting them via their 8-pin micro-
phone connectors. The operation is as follows (the transmit
transceiver is the source and the receive transceiver is a
target).
The following data cannot be cloned.
• Tuning data
• Embedded message with password
• Model name data
