4-1. Preface
The NXR-700 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-700 to the personal computer (IBM PC
or compatible) with the RS-232C Cross-cable. (Connection is
the same as in the PC mode.)
Notes:
You can only program fi rmware from the DB-9 COM con-
nector on the front panel. Using the 25-pin logic interface
on the rear panel will not work.
4-3. Programming
1. Start up the programming software (Fpro. exe).
The Fpro. exe exists in the KPG-109D 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 fi le name item.
4. Turn the NXR-700 power on.
5. Check the connection between the NXR-700 and the per-
sonal computer, and make sure that the NXR-700 is in the
program mode.
6. Press write button in the window. A window opens on
the display to indicate progress of writing.
7. If writing ends successfully, the NXR-700 restarts.
8. If you want to continue programming other NXR-700s,
repeat steps 3 to 6.
Notes:
It automatically enters the fi rmware program mode by the
writing request from the programming software (KPG-109D).
4-4. Function
Baud rate is decided automatically with setting of pro-
gramming software.
Note:
Normally, write in the high-speed mode (115200 bps).
