5-5. Programming With IBM PC

If data is transferred to the transceiver from an IBM PC
with the KPG-60D, the destination data (basic radio informa-
tion) for each set can be modified. Normally, it is not neces-
sary to modify the destination data because their values are
determined automatically when the frequency range (fre-
quency type) is set.
The values should be modified only if necessary.
Data can be programmed into the flash memory in RS-
232C format via the modular microphone jack.
KPG-60D instruction manual parts No. : B62-1315-XX.

6. Firmware Programming Mode

6-1. Preface
Flash memory is mounted on the TK-880. This allows the
TK-880 to be upgraded when new features are released in
the future. (For details on how to obtain the firmware, con-
tact Customer Service.)
6-2. Connection Procedure
Connect the TK-880 to the personal computer (IBM PC or
compatible) with the interface cable (KPG-46). (Connection
is the same as in the PC Mode.)
6-3. Programming
1. Start up the programming software (Fpro. exe).
2. Set the communications speed (normally, 57600 bps)
and communications port in the configuration item.
3. Set the firmware to be updated by File name item.
4. Turn the TK-880 Power ON with the [A] switch held
down. Hold the switch down until the display changes to
"PROG 57600". When "PROG 57600" appears, release
your finger from the switch.
5. Check the connection between the TK-880 and the per-
sonal computer, and make sure that the TK-880 is in the
Program mode.
6. Press write button in the window. A window opens on
the display to indicate progress of writing. When the TK-
880 starts to receive data, the [P] icon is blinking.
7. If writing ends successfully, the LED on the TK-880 lights
and the checksum is displayed.
8. If you want to continue programming other TK-880, re-
peat steps 4 to 7.
Notes :
• This mode cannot be entered if the Firmware program-
ming mode is set to Disable in the Programming soft-
ware (KPG-60D).
• When programming the firmware, it is recommend to
copy the data from the floppy disk to your hard disk be-
fore update the radio firmware.
Directly copying from the floppy disk to the radio may not
work because the access speed is too slow.
6-4. Function
1. If you press the [ ] switch while "PROG 57600" is dis-
played, the version is displayed. If you press the [ ]
switch again while the version is displayed, "PROG
57600" is redisplayed.
REALIGNMENT
2. If you press the [D] switch while "PROG 57600" is dis-
played, the display changes to "PROG 19200" to indicate
that the write speed is low speed (19200 bps). If you
press the [D] switch again while "PROG 19200" is dis-
played, the display changes to "PROG 38400", and the
write speed becomes the middle speed (38400 bps). If
you press the [D] switch again while "PROG 38400" is dis-
played, the display returns to "PROG 57600".
3. If you press the [D] switch while the version is displayed,
the checksum is displayed. If you press the [D] switch
again while the checksum is displayed, the version is
redisplayed.
Note :
Normally, write in the high-speed mode.
7. Self Programming Mode
Write mode for frequency data and signalling etc. Mainly
used by the person maintaining the user equipment.
7-1. Enter to the Self Programming Mode
Delete R614 (Figure 2) in the TX-RX unit and turn the
power switch on while pressing the [CALL] key. When en-
ter the self programming mode, "SELF PROG" is displayed.
Note :
This mode (self programming mode) cannot be set when
it has been disabled with the KPG-60D.
