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, XP or Vista (32-bit).
5-5. Programming software KPG-111D description
The KPG-111D is the programming software for the
transceiver supplied on a CD-ROM. This software runs un-
der Windows XP, Vista or 7 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.
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 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.
6-3. Programming
1. Start up the fi rmware programming software (Fpro.exe
(ver. 6.0 or later)). The Fpro.exe exists in the KPG-111D
installed folder.
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 [ ] key held
down. Then, the orange LED on the transceiver lights
and "PROGRAM 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 [LOADING] display lights.

REALIGNMENT
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 "PROGRAM 115200" is
displayed, the display changes to "PROGRAM 19200"
(The LED blinks green) to indicate that the write speed
is low speed (19200 bps). If you press the [ ] key again
while "PROGRAM 19200" is displayed, the display
changes to "PROGRAM 38400" (The LED lights red and
orange alternatively). If you press the [ ] key again while
"PROGRAM 38400" is displayed, the display changes
to "PROGRAM 57600" (The LED blinks orange). If you
press the [ ] key again while "PROGRAM 57600" is dis-
played, the display returns to "PROGRAM 115200" (The
LED lights orange).
2. If you press the [ ] key while "PROGRAM 115200" is
displayed, the checksum is calculated, and a result is dis-
played. If you press the [ ] key again while the check-
sum is displayed, "PROGRAM 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 master and the receive transceiver is a
slave).
The following data cannot be cloned.
• Tuning data
• Embedded message with password
• ESN (Electronic Serial Number) data
Note:
The following data can be cloned.
• Fleet (own)/ID (own) for FleetSync
• Unit ID (own) for NXDN
1. Turn the master transceiver power ON with the [ ] key
held down. If the read authorization password is set to
the transceiver, the transceiver displays "CLONE LOCK"
If the password is not set, the transceiver displays
"CLONE MODE".
2. When you enter the correct password, and "CLONE
MODE" is displayed, the transceiver can be used as the
cloning master. The following describes how to enter
the password.
