3-3. KPG-46/KPG-46A Description

(PC programming interface cable: Option)
The KPG-46/46A is required to interface the NXR-710 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 NXR-710 to the RS-232C serial port of the com-
puter.

3-4. 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).

3-5. Programming Software KPG-129D Description

The KPG-129D 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 NXR-710 and
edited on the screen. The programmed or edited data can
be printed out. It is also possible to tune the NXR-710.

4. Firmware Programming Mode

4-1. Preface
The NXR-710 uses fl ash memory to allow it to be easily
upgraded when new features are released in the future.
4-2. Connection Procedure
Connect the NXR-710 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.
4-3. Programming
1. Start up the fi rmware programming software (Fpro.exe
(ver. 4.1 or later)). The Fpro.exe exists in the KPG-129D
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 NXR-710 power ON with the [PF1] key held
down. Then, "P.G." is displayed.
5. Check the connection between the NXR-710 and the
personal computer, and make sure that the NXR-710 is in
the Program mode.
6. Press write button in the window. When the NXR-710
starts to receive data.
7. If writing ends successfully, the TX LED on the NXR-710
lights.
8. If you want to continue programming other NXR-710s,
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.
4-4. Function
If you press the [PF6] key while "P.G." is displayed, the
display changes to "P G" to indicate that the write speed
is low speed (38400 bps). If you press the [PF6] key again
while "P G" is displayed, the display changes to "P G." to
indicate that the write speed is mid speed (57600 bps). If
you press the [PF6] key again while "P G." is displayed, the
display changes to "P.G." to indicate that the write speed is
high speed (115200 bps).
Note:
Normally, write in the high-speed mode.
